Electric vehicles (EVs) significantly cut lifecycle greenhouse gas emissions in almost all circumstances and are the key technology for decarbonising road transport.

While not having a car has even larger climate benefits, many peoples’ ability to go car-free is limited by their circumstances and the availability of alternatives.

This means EVs are “likely crucial” for tackling transport emissions, according to the Intergovernmental Panel on Climate Change (IPCC).

EV sales are growing fast, accounting for one in every seven cars sold globally in 2022 – up from one-in-70 just five years earlier.

Yet EVs are also being subjected to relentless hostile reporting across mainstream media in many major economies, including the UK.

Here, Carbon Brief factchecks 21 of the most common – and persistent – myths about EVs.

FALSE: ‘An EV has to travel 50,000+ miles to break even’

One of the most common false claims made against EVs is that they offer little or no climate benefit over conventional cars, due to the emissions associated with making their battery.

In a Twitter post promoting his anti-EV comment article for the Daily Mail, for example, the climate-sceptic former Conservative peer Matt Ridley claimed:

“An EV has to travel 50,000+ miles to break even with an ICE [internal combustion engine] car. That number is growing, not shrinking.”

This is doubly false. As Carbon Brief showed in its 2019 factcheck, it takes less than two years for a typical EV to pay off the “carbon debt” from its battery. Over the full vehicle lifecycle, carbon dioxide (CO2) emissions from an EV are around three times lower than an average petrol car.

In reality, therefore, an EV in Europe will pay off its carbon debt after around 11,000 miles (18,000km), according to the International Council on Clean Transportation (ICCT).

Moreover, the lifecycle benefits of EVs are increasing over time as electricity grids get cleaner.

In a 2021 lifecycle analysis, the ICCT found that an EV bought in Europe would cut emissions by 66-69%, relative to a conventional car. By 2030, this emissions saving would rise to 74-77%, the ICCT said, “as the electricity mix continues to decarbonise”.

New Carbon Brief analysis shows that a Tesla Model Y, the world’s best-selling EV, would pay off its “carbon debt” after around 13,000 miles in the UK (21,000km), as shown in the figure below.

This would take less than two years for the average UK driver.

Typically, claims to the contrary argue that the higher emissions created during production of an EV are only very slowly paid off, or perhaps not at all, during the vehicles’ full lifecycle.

Yet these claims almost always make the same three key mistakes, which serve to underplay the emissions from combustion-engine cars and overestimate those from EVs.

First, these claims routinely overstate the emissions associated with manufacturing EV batteries, often cherrypicking older studies with the highest estimates.

Second, they usually take fuel-efficiency figures at face value, ignoring the long-standing issue that vehicle test cycles are unrealistic – with real-world efficiency around 40% worse than stated.

(Combustion-engine car test cycles were the subject of deliberate manipulation exposed by the “dieselgate” scandal. While real-world EV mileage is also lower than in test cycles and some electricity is lost during charging, this only adds around 19% to energy use, according to the ICCT.)

Third, they generally ignore the significant amount of CO2 associated with fuel production, including refining, which adds at least 20% – or more – to that emitted from the car’s tailpipe.

Taking these together, the ICCT concludes that combustion-engine cars have lifecycle emissions that are “twice as high as official tailpipe CO2 values”.

FALSE: ‘VW’s e-Golf becomes more environmentally friendly only after 77,000 miles’

In order to support their false claims about the climate benefits of EVs, many articles refer to figures published several years ago by carmaker VW.

These studies have an air of credibility – after all, surely the manufacturers know best about their own supply chains? Yet both have been comprehensively – and repeatedly – corrected.

A few days before publishing Ridley’s false claims in July 2023 (see above), the Daily Mail published a news article including almost identical inaccuracies about the emissions benefits of EVs:

“The environmental benefit of electric cars may never be felt – with their production creating up to 70% more emissions than their petrol equivalent. Electric cars need to be used for tens of thousands of miles before they offset the higher releases, with VW’s e-Golf becoming more environmentally friendly only after 77,000 miles, according to the manufacturer’s own figures.”

There are several issues with these figures, including the fact that the e-Golf was discontinued three years ago. More substantively, the figures behind the VW analysis – shared with Carbon Brief in 2020 – show that the company makes the same key errors identified above. (See: FALSE: ‘An EV has to travel 50,000+ miles to break even’.)

Specifically: VW overestimates the emissions associated with making batteries; VW fails to account for the real-world fuel economy of its diesel Golf; VW underestimates the emissions associated with diesel fuel production; and VW overestimates the emissions in EU electricity.

Correcting for these errors shows that the e-Golf – if it were still being produced – would pay off its carbon debt after closer to 14,000 miles, or less than two years of UK average mileage.

The discontinued e-Golf would be better for the climate than a diesel_br_within 14,000 miles – not 77,000 miles as claimed by VW (1)

Carbon Brief and others corrected these figures from VW at the time – and they no longer appear on the VW website – yet they continue to be repeated in media attacks on EVs.

FALSE: ‘The electric Volvo C40 needs to be driven around 68,400 miles to cut carbon’

Newspapers have also continued to reuse estimates of the climate impact of Volvo’s EVs, published in 2021, which, as with those from VW, have been repeatedly corrected.

For example, a July 2023 article in the Daily Mail wrote:

“Volvo revealed in 2021 that the emissions from the production of electric cars can be up to 70% higher than petrol models and said it would require between 30,000 and 68,400 miles for an EV to become greener overall.”

This is recycled wording from the newspaper’s 2021 article, which had said:

“Volvo estimated that an electric Volvo C40 needs to be driven around 68,400 miles to have a lower total carbon footprint than its petrol equivalent, if the former is powered by the current global electricity mix.”

The Daily Mail’s repetition ignores a 2021 correction from Auke Hoekstra, a researcher at Eindhoven University of Technology (TU Eindhoven).

Hoekstra said Volvo overestimated the emissions in electricity generation, overestimated the fuel efficiency of its petrol car and underestimated the emissions associated with fuel production.

Overall, Hoekstra estimated that the Volvo C40 EV would pay off its “carbon debt” relative to a petrol XC40 after 16,000 miles, rather than the top-end 68,400 miles quoted by the Daily Mail.

@AukeHoekstra on X: British media and @VolvoCarUK are resuscitating an erroneous study I corrected before in #Astongate.

Interestingly, Volvo itself says in its 2021 report that – even with its disputed figures – its C40 EV shows a “great reduction” in emissions compared with a petrol equivalent:

“The carbon footprint [of an electric C40 Recharge] shows a great reduction in greenhouse gas emissions compared to that of an internal combustion engine (ICE) vehicle.”

Elsewhere in the report, Volvo notes that its assumptions are “conservative” and that, for example, it is “highly probable” that the carbon intensity of electricity generation will improve rapidly during the lifetime of an EV, meaning its results are “likely to overestimate the total carbon footprint”.

The manufacturer also says: “Volvo Cars has committed to only sell fully electric cars by 2030.”

FALSE: ‘Electric vehicles have little or no CO2 advantage over the car you already drive’

Some newspapers have gone a step further in their attacks on EVs, falsely suggesting that they may not benefit the climate at all compared with combustion-engine cars.

The Daily Express gave climate-sceptic motoring lobbyist Howard Cox a July 2023 comment slot to argue: “Electric vehicles have little or no CO2 advantage over the car you already drive.”

As explained above, EVs cut lifecycle emissions relative to combustion-engine cars by around two-thirds in Europe – and this figure is expected to climb.

After an average petrol car has been driven for 14 years – the UK-average age at scrappage – its carbon footprint would be 45 tonnes of CO2 (tCO2), illustrated by the black line in the chart below.

In contrast, an electric Tesla Model Y would emit 14tCO2 – a saving of 30tCO2 or 68%. This is shown by the curved red line, with the Tesla’s annual impact falling as the grid is decarbonised.

Indeed, a petrol car driven a UK annual-average of 7,400 miles emits nearly 3tCO2 every year thanks to the emissions from burning its fuel. (This is based on 2019 average mileage, as driving distances have yet to recover to pre-Covid levels.)

For comparison, global CO2 emissions are an average of 4.7t per person per year, 5.1tCO2 in the UK and 14.9tCO2 in the US. The average for Africa is 1.0tCO2 per person per year.

In support of his false claim that EVs do not have an emissions advantage over combustion-engine cars, Cox cites a self-published report that his organisation, FairFuel UK, funded with the Alliance of British Drivers and the Motorcycle Action Group. No authors are listed.

The report’s references include the notorious climate-sceptic blogs Watts Up With That? and JunkScience, an article in the Jaguar Drivers’ Club in-house magazine, and the climate-sceptic lobby group the Global Warming Policy Foundation and its campaigning arm Net Zero Watch.

The report’s false assertions are at odds with analysis published by the IPCC, the ICCT, the British and US governments and many others.

FALSE: ‘Climate change is accelerating because of the ban on combustion-engines’

German magazine Der Spiegel has published even more outlandish claims about EVs.

In an August 2023 article, it quotes the former head of the ifo institute Hans-Werner Sinn saying that “climate change is accelerating because of the ban on combustion-engines”.

The quote comes from an interview Sinn gave to German tabloid Bild. He argued that while EVs might reduce oil demand and emissions in one country, this is simply displaced elsewhere.

Notably, Sinn is contradicted not only by the expected climate benefits of EVs in the future, but also by the evidence of their emissions impact in the recent past.

@DrSimEvans on X: Global CO2 emissions will grow by less than 1% (300MtCO2) this year, according to new @IEA analysis

In an October 2022 analysis, the International Energy Agency (IEA) said that EVs and renewable energy sources had prevented some 600m tonnes of CO2 (MtCO2) emissions last year. It said:

“The rise in global CO2 emissions this year [2022] would be much larger – more than tripling to reach close to 1bn tonnes – were it not for the major deployments of renewable energy technologies and electric vehicles (EVs) around the world.”

In separate analysis published in April 2023 and covered by Carbon Brief, the IEA said that the EVs sold in 2022 alone had cut global emissions by 80MtCO2.

The IEA added that, by the end of the decade, EV sales were on track to displace 5m barrels of oil demand per day – some 5% of the current total – and to cut annual global emissions by 700MtCO2, roughly the current yearly output of Germany or Saudi Arabia.

FALSE: ‘Old bangers are the green motorist’s choice’

Another common argument against the adoption of EVs is that keeping older cars – colloquially known in the UK as “bangers” – would be more environmentally friendly than buying a new model.

Writing in the Guardian in June 2023, for example, comedian Rowan Atkinson said that “keeping your old petrol car may be better than buying an EV”.

(The Guardian subsequently published a factcheck of Atkinson’s claims, including this one.)

Atkinson’s argument was supported by letter-writers to the Sunday Times, which published their missives under the headline: “Old bangers are the green motorist’s choice.”

A 2021 comment for the Daily Telegraph by assistant editor Jeremy Warner was more definitive:

“If you want to do your bit for the planet, forget Tesla and other super expensive electric vehicles; just carry on driving the same old gas-guzzling banger you’ve always had. As much if not more carbon tends to be expended producing a new car as actually driving it.”

Avoiding the premature scrapping of functioning vehicles makes financial sense. Indeed, this is embedded in government plans to ban the sale of new combustion-engine cars by 2035 or before.

(The UK government had pledged to ban new combustion-engine car sales from 2030, with hybrid vehicle sales allowed to continue until 2035. It has since pushed back the ban to 2035.)

Given a lifetime of around 15 years, a 2035 ban would ensure that combustion-engine cars are off the road by 2050, when CO2 emissions need to reach net-zero to limit warming to 1.5C.

Yet, perhaps counterintuitively, it would still be a net benefit for the atmosphere to retire an “old banger” early in favour of an EV, Carbon Brief analysis shows.

Despite the bump in CO2 from manufacturing an electric car and its battery, a new EV would start cutting emissions after 20,000-32,000 miles in the UK (32,000-50,000km), per the chart below.

This means that an average UK driver replacing an “old banger” would pay off the carbon debt from buying a new EV within around four years, with the exact timelines depending on the fuel efficiency of the car being scrapped, annual mileage and the battery size of the new EV.

(The Sunday Times letter-writer driving a 36-year old Mercedes only 5,000 miles a year would start cutting emissions with a new Tesla Model Y after five years.)

FALSE: ‘EVs simply displace carbon emissions from roads to distant power stations’

A common refrain from those arguing that EVs are “nowhere near as green as you think”, in the words of climate-sceptic columnist Ross Clark in the Daily Mail, is that “driving an electric car simply displaces carbon emissions from roads to distant power stations”.

This argument is often misleadingly used to suggest that EVs are powered wholly or mainly on fossil fuels – with the implication that they are, therefore, unlikely to cut emissions. Clark says:

“If all the electricity used to power a car comes from coal – China and Poland, for example, have large numbers of coal power stations – you would need to drive 78,700 miles before your electric car’s carbon ‘budget’ broke even.”

First, there are no countries in the world that generate all of their electricity from coal. In China, the share of coal power was 61% in 2022, down 14 percentage points in a decade, with the equivalent figures in Poland being 69% and a reduction of 15 points.

Second, Carbon Brief analysis shows EVs would pay off their carbon debt in China and Poland after 22,000 miles (35,000km) and 18,000 miles (28,000km), respectively.

An academic analysis of EVs in China found they already cut carbon emissions by 40% relative to combustion-engine cars in 2020, with a further 43% reduction possible by 2030.

In general, EVs cut carbon emissions significantly, even if they mainly run on coal- or gas-fired electricity, as the chart below shows. In coal-heavy Poland, an EV would cut lifecycle emissions by two-fifths, Carbon Brief analysis shows, rising to two-thirds in the UK and four-fifths in Norway.

EVs cut carbon significantly, even when they mainly run on coal power

In its latest assessment report, the Intergovernmental Panel on Climate Change (IPCC) spelled this out, but added that EVs already cut emissions in almost all cases. It said:

“The extent to which EV deployment can decrease emissions by replacing internal combustion engine-based vehicles depends on the generation mix of the electric grid although, even with current grids, EVs reduce emissions in almost all cases.”

The IPCC went on to note that investments in EVs are “convertible” into low-carbon assets, even in countries with very carbon-intensive electricity:

“Today’s investments in electric vehicles in settings where electricity is produced with fossil fuels is an example of convertible investments – they will be decarbonised once electricity production has switched to renewable energies.”

The reason that EVs can cut emissions, even when running on fossil-heavy electricity, is that they are roughly four times more energy efficient than combustion-engine cars.

MOSTLY FALSE: ‘Electric cars are not green machines’

As noted above, many attacks on the climate benefits of EVs are completely false. Yet it is also the case that there is a non-trivial carbon footprint associated with the production and use of EVs.

For some commentators, this is an opportunity to make the perfect the enemy of the good, with a recent Daily Mail headline stating: “Electric cars are NOT green machines.”

When an EV bought in the UK today would cut emissions by two-thirds, relative to a combustion-engine car, it is obvious which is the “greener” choice.

Yet with a lifecycle carbon footprint of 20 or even 30tCO2, depending on lifetime mileage, location and the size of the EV battery, there is clearly scope for EVs to become lower-carbon in the future.

Ragout_Daily mail – why electric cars are not green machines

This is already expected to happen to some extent – as already noted – as electricity grids are decarbonised around the world. But mining, battery manufacturing and the production of steel, aluminium and other components all add to EVs’ footprint overall.

The IPCC says, with high confidence, that EVs running on low-carbon electricity “offer the largest decarbonisation potential for land-based transport, on a lifecycle basis”. But it also notes:

“Further efforts to reduce the GHG footprint of battery production…are essential for maximising the mitigation potential of BEVs [battery EVs].”

In other words, EVs are central to decarbonising road transport, but more needs to be done to ensure their production and use has the lowest-possible emissions.

The Daily Mail draws a different conclusion, continuing its headline by stating falsely:

“The environmental benefit of EVs may never be felt as their production creates up to 70% more emissions than petrol equivalents.”

While it is true that the production of EVs creates more CO2 than petrol equivalents – the US Argonne National Laboratory puts manufacturing-phase emissions at some 30-100% higher, depending on battery size – this carbon debt is paid off quickly. (See: FALSE: ‘An EV has to travel 50,000+ miles to break even.’) As a result, EVs still cut carbon significantly overall.

Moreover, the Argonne analysis says EVs’ production-phase disadvantage will shrink significantly by 2030-2035, falling to 5-50%, as supply chains become lower-carbon and more efficient.

It also notes the potential for steel decarbonisation to be a “major source of opportunity for emissions reduction” in the future – for example, using “green steel” produced without burning coal.

INCOMPLETE: ‘Electric vehicles alone can’t solve climate change’

Among all the myths about EVs, it can be easy to lose sight of one important point, summarised in the headline of a recent Bloomberg editorial: “Electric vehicles alone can’t solve climate change.”

On the one hand, this statement is trivially true, in the sense that it could equally be applied to any individual climate solution. On the other hand, this statement is also incomplete.

No serious strategy for decarbonising road transport – let alone the entire global economy – could rely on EVs alone. But this is hardly a reason to push back on the adoption of EVs.

On the contrary, the IPCC concludes that EVs are “likely crucial”. Its latest report says:

“Widespread electrification of the transport sector is likely crucial for reducing transport emissions.”

Indeed, the IPCC finds that EVs – along with other zero-carbon fuels – likely have the single-largest potential to cut transport emissions. Moreover, it puts the carbon-cutting potential of these technologies ahead of changes to urban infrastructure and behaviour.

The IPCC says EVs and other technological changes can contribute an estimated 50% of emissions cuts in the land transport sector by 2050, with a range of 30-70%. It says:

“Technology adoption, particularly banning combustion and diesel engines and 100% EV targets (and other zero-carbon fuels, especially in freight) and efficient lightweight cars, can contribute to between 30% and 70% of GHG emissions reduction from land transport in 2050, with 50% as our central estimate.”

This is well ahead of the potential from changes in urban infrastructure (30%, range 20-50%), behavioural change (5%, range up to 15%) and active travel (2-10%), according to the IPCC.

As a result, the IPCC concludes with high confidence that:

“Several end uses, such as passenger transportation (light-duty electric vehicles, two and three wheelers, buses, rail)…are likely to be electrified in net-zero energy systems.”

Nevertheless, the IPCC makes clear that other options for cutting transport emissions are an important part of the solution for reaching net-zero emissions globally.

On urban infrastructure, the IPCC says:

“Infrastructure use (specifically urban planning and shared pooled mobility) has about 20-50% (on average) potential in land transport GHG emissions reduction, especially via redirecting the ongoing design of existing infrastructures in developing countries, and with 30% as our central estimate.”

On behaviour change, the IPCC says:

“[S]ocio-cultural factors can contribute up to 15% to land transport GHG emissions reduction by 2050, with 5% as our central estimate. Active mobility, such as walking and cycling, has 2-10% potential in GHG emissions reduction.”

(At a household level, the IPCC cites findings showing that “liv[ing] car-free” is the single-most effective individual action, with the potential to cut emissions by around 2tCO2 per person per year. Shifting from a combustion-engine car to an EV would have a similar impact, it notes.)

Overall, it is clear from the IPCC report that EVs are “crucial” to decarbonising transport, but also that they cannot do the job alone. In addition, EVs will only reach their full carbon-cutting potential if electricity systems and manufacturing supply chains are also decarbonised.

FALSE: ‘EVs are [low-mileage] runabouts…[that] take a long time to pay off their carbon debt’

In a July 2023 article for the Daily Mail, climate-sceptic columnist Ross Clark falsely claims that EVs will take a long time to pay off their “carbon debt” of manufacturing, because they are mostly “used as runabouts in towns and cities”.

He asserts, without evidence, that the mileage of EVs is low due to “their limited range”. A cursory glance at real-world data shows these claims to be false.

New EVs in the UK drive an average of 9,435 miles per year in the first three years of their life, according to analysis of MOT data from the RAC Foundation. This is well above the average for UK cars overall and 26% further than the average new petrol car, the analysis finds.

(The figures also show new diesels covering 12,496 miles per year. However, diesel cars are rapidly becoming less popular, accounting for less than 4% of sales in 2023 to date.)

Figures from Norway paint a similar picture. EVs now drive more miles each year, on average, than petrol or diesel cars, according to the latest official figures discussed by BloombergNEF head of transport Colin McKerracher in an article for Bloomberg. He writes:

“This effect shouldn’t be surprising; people like to use more of things that are cheaper. But it wasn’t always received wisdom in the market. A few years ago, some oil energy outlooks assumed not only that EV adoption would be muted, but that each EV would on average travel less than a comparable internal combustion vehicle. This now looks like a very shaky assumption…at BNEF, we’re expecting this same effect to start showing up in the data of more countries in the years ahead.”

FALSE: ‘Synthetic petrol could displace electric vehicles’

In early 2023, an EU rule banning the sale of new combustion-engine cars from 2035 was delayed by several weeks after Germany insisted on an exemption for cars running on “e-fuels”.

Sometimes referred to as “synthetic fuels”, they are made by combining CO2 with hydrogen and can be used in existing combustion-engines. If they are made with low-carbon hydrogen, synthetic fuels can have a low carbon footprint overall.

These apparent advantages have persuaded some politicians and commentators to argue for their widespread use, with some going so far as to suggest they could “stop electric cars in their tracks”.

For example, in a since-corrected comment for the Guardian, comedian Rowan Atkinson argued that “a sensible thing to do would be to speed up the development of synthetic fuel”.

In March 2023, the UK parliamentary select committee on transport also argued in favour of using synthetic fuels, in a report that received positive media coverage, stating:

“[D]rop-in sustainable fuels enables us to address the existing fleet and minimise cost (and carbon emissions) through the use of existing infrastructure. It would also enable more socially equitable access to carbon reduction technologies for everyday transport as it would not be necessary to buy a new electric car and have access to charging infrastructure.”

The recent interest in synthetic fuels has been co-opted by those seeking to delay the UK government’s pledged ban on sales of new combustion-engine cars.

Such calls, including lobbying from the UK’s fuel producers, were rejected by the government on the basis that synthetic fuels are “expensive”, “not proven” and contribute to air pollution.

Synthetic fuels are indeed costly. They are ”up to three times more expensive than conventional fossil fuels”, according to the IPCC, and “expensive…even in the long run”, says the IEA.

They are also very inefficient to produce. Carbon Brief analysis shows it would take at least five times as much electricity to run cars on e-fuels as for EVs.

@DrSimEvans on X: Running all of the UK's cars on synthetic 'e-fuels' would take FIVE TIMES as much electricity as for EVS.

EVs running on renewables also have significantly lower CO2 emissions than cars burning e-fuels made from the same source of power, according to lifecycle analysis for the UK government.

(According to NGO Transport & Environment, lifecycle emissions from an EV in 2030 would be 53% lower than for a combustion-engine car running on e-fuels.)

These issues make it vanishingly unlikely that synthetic fuels will “displace” EVs, let alone “stop electric cars in their tracks”. The IPCC explains that synthetic fuels will be relatively scarce and expensive, with their use focused on harder-to-abate sectors such as aviation. It says:

“Given these high costs and limited scales, the adoption of synthetic fuels will likely focus on the aviation, shipping and long-distance road transport segments, where decarbonisation by electrification is more challenging.”

Indeed, the head of German airline Lufthansa recently pushed back against the use of synthetic fuels for cars. Referring to moves by luxury carmaker Porsche to get exemptions from combustion engine bans based on e-fuels, he said:

“With no technology in sight to replace fuels, we really need all the sustainable aviation fuel in the world…[Porsche chief executive] Oliver [Blume] can maybe have some for his 911, but we really need the volumes.”

Mercedes-Benz chief executive Ola Källenius, at least, has acknowledged this reality, stating: “As for carbon-reduced fuels…aviation will need them.”

A 2021 briefing from Transport and Environment concluded bluntly: “E-fools: why e-fuels in cars make no economic or environmental sense.”

A June 2023 article for the Evening Standard was titled, “Synthetic petrol could displace electric vehicles” – but went on to undermine its own headline. The piece asked: “Could e-fuels completely derail attempts to phase out the internal combustion engine?” It then answered: “[T]here’s no suggestion e-fuels are a credible like-for-like replacement for today’s petrol use.”

FALSE: ‘Hydrogen cars are more sustainable than EVs’

Hydrogen cars are another favourite of those disputing the benefits of EVs. In his Guardian article criticising EVs, for example, Rowan Atkinson said hydrogen was an “interesting alternative fuel”.

Elsewhere, a recent feature in the Times is titled: “Hydrogen cars were the future once – might they be again?” Going a step further is an article from “sustainable living” website the Ethos, which claims falsely that “hydrogen cars are more sustainable than EVs”

In a since-deleted article for the Daily Express, the founder of a firm hoping to make hydrogen from waste plastic writes glowingly of its potential and says that EVs are “destined to go the way of the dodo”.

The evidence, however, paints a very different picture, both in terms of the prospects for hydrogen versus electrified transport and when it comes to their relative sustainability.

There were only 72,000 hydrogen fuel-cell vehicles on the planet at the end of 2022, against 26m EVs, according to the IEA. This means there were already 360 times more EVs than hydrogen vehicles at the end of 2022, as shown in the figure below.

With EV sales set to climb by 40% to 14m units in 2023 and hydrogen vehicle sales falling, this chasm is set to widen even further.

Hydrogen vehicles are a 'rounding error' compared with EV sales

According to Colin McKerracher, head of advanced transport for BloombergNEF, fuel-cell vehicle sales are “a rounding error” relative to sales of EVs, despite the fact that governments have “bent over backwards to make their support as technology-neutral as possible”. He writes:

“A dearth of government support isn’t the issue for alternatives to battery EVs – the problem is the product. Fuel cell vehicles are failing because they’re not proving compelling enough.”

As to the false idea that hydrogen cars are more sustainable than EVs, this is at odds with the findings of a lifecycle analysis for the UK government.

This analysis found that EVs are “much more efficient” than hydrogen cars, using only a third of the energy. It also said lifecycle emissions from hydrogen cars would be 60-70% higher than EVs, even assuming that the hydrogen was from low-carbon sources.

The latest IPCC report concluded that EVs are “the most attractive” option for cars, whereas hydrogen vehicles could “complement” EVs in heavy-duty transport.

FALSE: ‘Sales of electric vehicles appear to be slowing’

One bizarrely persistent myth is that consumer appetites are turning away from EVs. An October 2022 article in the Times, for example, said that “sales of electric vehicles appear to be slowing”.

This is false: indeed, EVs sales are surging in the UK and globally. Yet a September 2023 Times article said the “popularity of electric cars (EVs) continues to wane”.

The Daily Telegraph’s climate-sceptic columnist Matthew Lynn may have marked the apogee of this trend with a comment headlined: “Nobody wants an electric car”. (Lynn also wrote in a 2007 article for the New Zealand Herald that the iPhone “won’t make a long-term mark on the industry”.)

It is easy to see why some newspapers and columnists have been blindsided by the pace of change. In 2017, only one in every 70 new cars sold was an EV (1.4%). Just five years later, in 2022, this had risen to one in seven (14.4%), according to figures from the IEA.

In April 2023, the IEA said “explosive” growth would see EVs making up 18% of global car sales in 2023, just two years after saying that threshold would not be crossed until after 2030.

@DrSimEvans on X: 'Explosive' growth means 1-in-3 new cars will be electric by 2030, new @IEA report says

A slow initial phase followed by increasingly rapid growth is characteristic of the “S-curve” of technology adoption, which has been followed by mobile phones and now EVs.

In the UK, EV sales grew 88% in July 2023 compared with the same month a year earlier and 72% in August. Some 16.4% of sales in the first eight months of 2023 were “pure” EVs with no combustion engine, up from 14.0% in the same period of 2022.

The UK has also seen rapid expansion in the second-hand market for EVs, which grew by 81% in the second quarter of 2023, albeit from a low base.

Forecasts from industry group the Society of Motor Manufacturers and Traders (SMMT) show pure electric cars and vans roughly doubling and tripling their shares of sales, to 22.6% and 11.2%, respectively, between 2021 and 2024. This would put them on track to meet the requirements of the UK’s recently confirmed “zero emissions vehicle” (ZEV) mandate, which enters force in 2024.

The world’s top 10 markets for EVs all saw double-digit growth in sales during the second quarter of 2023, Bloomberg reports, including China, the US, Germany and France.

@tsrandall on X: If anyone tries to tell you EV sales are plateauing, just look at the latest growth rates of the 10 biggest markets.

While there is a wide range of views over how quickly the shift to EVs will happen, even oil producers’ cartel OPEC agrees that their sales and market share will grow rapidly.

The IEA says EVs will make up a third of global car sales by 2030, with BloombergNEF saying 45%. The most aggressive recent forecasts for EVs come from the Rocky Mountain Institute (RMI) and use S-curves to predict a global EV share of 60-80% by 2030.

For context, some 37% of car sales in China in August 2023 were EVs or “plug-in” hybrids, BloombergNEF says.

FALSE: ‘Electric cars could soon be more expensive to drive than their petrol equivalents’

One of the most obvious advantages of electric cars is their much lower running costs, relative to combustion-engine equivalents. This is largely a result of their far greater efficiency.

In an October 2023 article, the UK’s Climate Change Committee (CCC) says EVs “will be significantly cheaper than petrol and diesel vehicles to own and operate over their lifetimes”.

Indeed, Carbon Brief analysis shows that EV drivers would make significant savings over using a petrol car in all countries considered, from Australia to Argentina and from China to India, the US, or the UK. Annual EV savings, for a selection of these countries, are shown in the figure below.

Yet a number of newspaper articles have sought to paint a different picture.

In August 2022, for example, the Daily Telegraph reported: “Electric cars could soon be more expensive to drive than their petrol equivalents amid soaring energy prices.”

This supposed future – when EVs “could soon be more expensive to drive” – never came to pass.

The chart below illustrates the lower fuel costs of EVs in a varied range of countries, including COP28 host the UAE, as well as the US, China, India, UK and EV frontrunner Norway.

For each country, the chart shows annual fuel costs for an EV in red, based on standard domestic electricity prices as of mid- to late-2023, depending on data availability. This is compared with the equivalent annual cost for a petrol car in grey, based on pump prices in October 2023.

More recently, in July 2023, the Daily Mail published a similar article questioning the cost savings of EVs. However, it made a narrower and much more carefully worded claim. It said: “Recharging electric cars at public points can now prove more expensive than a petrol refill.”
In the UK at least, this can be true, depending on the fuel efficiency of the petrol and electric cars, the prevailing price of fuel and the type of public charge point used, given fast chargers are more expensive than home charging. Nevertheless, the statement is incomplete – and, therefore, potentially misleading.

@KatyDuke on X: Latest BEV V ICE fuel costs. ICE = 19.8p per mile, diesel 17.2p pm.

Crucially, the majority of UK homes have access to off-street parking and owners usually charge their EVs overnight, using off-peak tariffs that are cheaper than standard home electricity prices.

While EVs cost significantly less to drive than petrol cars, they generally remain more expensive to buy. This is despite rapid declines in the cost of batteries over the past decade.

The IPCC’s latest report said that EV costs “are decreasing”. In its latest 2023 EV outlook, research firm BloombergNEF said price parity with combustion-engine cars “is getting closer”.

The outlook explained:

“EV price parity is getting closer, but progress varies by segment and country. Prices for lithium-ion batteries increased for the first time in 2022 and are likely to remain elevated in 2023. This delays the upfront price parity of battery electric vehicles with combustion cars. Despite the near-term increase, EVs still reach up-front price parity with comparable combustion vehicles, without subsidies, by the end of the decade in most segments.”

The outlook shows EVs reaching up-front price parity with combustion vehicles in the SUV and large car segments in Europe by 2025, with small and medium cars following by 2028.

(According to data firm Benchmark Mineral Intelligence, lithium-ion battery prices dipped below $100 per kilowatt hour in August 2023 for the first time since two years earlier.)

While they have yet to reach up-front price parity, the total cost of ownership of EVs reached parity with combustion-engine cars “in leading markets outside the US in the early 2020s”, according to RMI, thanks to lower running costs. Similarly, a recent analysis for the German government found “clear advantages for electric cars”, when looking at the total cost of ownership.

More recently, Bloomberg published a chart, below, showing that Tesla’s Model 3 and Model Y are now cheaper than the average selling price of a new car in the US.

@tsrandall on X: At the start of the year Tesla's base Model Y cost $20,000 more than the average selling price of a new car in the US.

(In October 2022, the Sun was among newspapers giving coverage to a woefully wrong analysis of the costs of the shift to EVs, commissioned from motoring campaign group Fair Fuel UK from economic consultancy the Centre for Economics and Business Research. In order to reach its paid-for conclusions, the consultancy incorrectly claimed that EVs cost more to run than petrol cars and makes the “simply perverse” assumption that the upfront cost of EVs would never change.)

FALSE: ‘There are insufficient raw materials…for all vehicles to be EVs’

Another common line of attack against the widespread adoption of EVs relates to the metals needed to make lithium-ion batteries.

In a March 2023 report, for example, the transport select committee of MPs in the UK parliament claimed – falsely – that “there are insufficient raw materials…for all vehicles to be EVs”.

This assertion does not appear to be supported by any evidence in the committee’s report. It also stands in stark contrast to the findings of the Energy Transitions Commission (ETC), which said in a July 2023 report that there was “no fundamental shortage” of any key materials. It said:

“There is no fundamental shortage of any of the raw materials to support a global transition to a net-zero economy: geological resources exceed the total projected cumulative demand from 2022-50 for all key materials, whether arising from the energy transition or other sectors.”

Writing in the Financial Times on the launch of the report, ETC chair Adair Turner said “myths” were “clouding the reality of our sustainable energy future”. He said it was important to separate those myths from genuine concerns and added:

“One thing we don’t need to worry about is long-term supply: for all the key minerals, known resources easily exceed total future requirements.”

It is clear that the shift to EVs will significantly increase demand for a number of “critical minerals”, including lithium, but also nickel, cobalt and others.

The IEA, for example, says that demand for critical minerals would grow by three-and-a-half times between 2023 and 2030 to reach 30m tonnes a year, if countries get on track to limit warming to 1.5C. It adds that EVs and batteries would be the main drivers of this demand growth.

In its July 2023 critical minerals market review, the IEA highlights the need to address mining environmental impacts, as the shift towards net-zero drives demand for minerals. It says:

“The mining industry has been associated with a host of negative environmental, social and governance (ESG) impacts, including human rights violations, contribution to armed conflict, environmental contamination, deforestation and other harms. Failure to manage these impacts could have profound implications for clean energy transitions as well as damage the environment and communities in the vicinity of mining deposits.”

These issues have prompted a torrent of media coverage, with headlines including one in the Daily Telegraph saying: “The green revolution is fuelling environmental destruction.” Elsewhere, the Washington Post ran a series of articles in early 2023 with the tagline “clean cars, hidden toll”.

Such coverage generally fails to offer perspective on the scale of resource extraction needed to support the world’s current fossil-fueled economy.

@DrSimEvans on X: Factcheck (true): Mining causes environmental problems

Some 15bn tonnes of fossil fuels are extracted and burnt each year. Under a 1.5C pathway, critical mineral needs would be 500 times lower, reaching 30m tonnes a year by 2030.

Making a similar point, Turner writes in his Financial Times article:

“Mineral supply challenges must be clearly faced and managed. But we must also welcome the sustainable nature of the new energy system. In today’s energy system, each year we burn 8bn tons of coal, 35bn barrels of oil, and 4tn cubic metres of gas, producing around 40bn tonnes of CO2 equivalent. In the new system, we extract far smaller quantities of key minerals and place them in structures that generate, store and use clean electrical energy; and the materials are then ready to do the same again next year or to be recycled over and over again. This is an inherently renewable system and the faster we build it the better.”

Turner also says that, setting aside the “myths”, there are “three key challenges” around critical minerals. These include scaling up supply fast enough to meet rising demand and diversifying supply chains, which are currently concentrated in a small number of countries.

His third challenge is the environmental impacts of mining:

“[N]ew developments can have adverse local environmental effects. In aggregate, the adverse effects will be more than offset by putting a stop to coal mining but that won’t be true for some local communities. Best mining and refining practices can dramatically reduce harm – and must be required by regulation imposed on mineral producers and users.”

FALSE: The lifetime of EV batteries is ‘horribly uncertain’

Over the years, many newspaper articles have raised questions over the longevity of EV batteries. Back in 2010, a Daily Telegraph article said the lifetime of batteries was “horribly uncertain” and predicted that this would make EVs “financially disastrous”.

In fact, most manufacturers offer battery warranties of at least eight years – and EVs do not depreciate any faster than conventional cars.

Still, even carmakers acknowledge that – perhaps not surprisingly – consumers remain uncertain about battery life, with Chinese-owned UK brand MG stating on its website: “Electric car battery life is one of the main factors that makes drivers reluctant to switch to an electric vehicle.”

UK motoring website Autocar notes that there are many “rumours and anecdotes” circulating about EV batteries failing “after a relatively short space of time”. It points to peoples’ experience with mobile phone batteries as one reason why such ideas persist.

However, Autocar goes on to say that most batteries will last the lifetime of the car. (Tesla says its batteries are “designed to outlast the vehicle”.) Autocar says:

“[T]he more electric cars that are out there and the longer they are run for, the more evidence is produced to show that the power pack will often last the lifetime of the car.”

A study of 15,000 EVs by Seattle-based battery analysis firm Recurrent Motors found that only 1.5% of batteries had been replaced. According to coverage of the study in the Globe and Mail, 90% of the cars that had covered over 100,000 miles still had at least 90% of their original range.

In a 2022 interview with Forbes, Nissan UK marketing director Nic Thomas is quoted saying:

“Almost all of the [electric car] batteries we’ve ever made are still in cars…And we’ve been selling electric cars for 12 years…It’s the complete opposite of what people feared when we first launched EVs – that the batteries would only last a short time”

UK roadside assistance firm RAC says: “For all intents and purposes, the lifespan of EV batteries…is broadly comparable to that of a traditional combustion car.”

FALSE: ‘Electric vehicles can explode – petrol ones only do it in movies’

In a July 2023 article for the Sun, climate-sceptic motoring journalist Jeremy Clarkson wrote that EVs were “bloody dangerous”, as part of a lengthy and familiar list of their supposed issues.

His comment piece ran under the false and – presumably – tongue-in-cheek headline: “Electric vehicles can explode – petrol ones only do it in movies.”

If this was meant as a joke, it fell flat. It was also flat-out wrong. Indeed, the evidence does not support Clarkson’s viewpoint at all – quite the opposite.

Figures from Norway, where more than a fifth of cars on the road are electric, show that standard combustion engine vehicles catch fire around five or six times more often than EVs.

Emergency services were called to around 30 fires per 100,000 standard cars on the road per year during 2018-2022, compared with around five EV fires per 100,000 vehicles, according to the data compiled by Robbie Andrew of the Cicero climate research institute in Oslo, using figures from the Norwegian Directorate for Civil Protection and Emergency Planning (DSB) and Statistics Norway.

@robbie andrew on X: Norway is known for having a large share of electric cars on its roads, currently over 21%.

In a Twitter thread, Andrew translates reporting from Norway saying that EV fires rarely involve the battery and that, asked by a journalist how much people should “fear” fires in electric cars, the senior engineer at DSB says: “To a very, very small extent.”

(Andrew notes that the discrepancy could be partly down to the EV fleet being relatively new on average. He has previously pointed to major flaws in a widely shared study, from price comparison website AutoinsuranceEZ, which claimed to show that EVs suffer fewer fires than other cars.)

Several other sources confirm that EVs are much less likely to catch fire than combustion-engine vehicles. For example, Australian EV news site the Driven cited figures from the Swedish Civil Contingencies Agency: “Petrol and diesel cars 20 times more likely to catch fire than EVs.”

Such is the interest in supposedly widespread EV fires, however, that certain media outlets have ended up falsely blaming the vehicles for fires they did not cause.

For example, the Daily Telegraph was one of several publications reporting a cargo ship fire in July 2023 as being “linked” to electric cars on board. On the day of the fire, on the Fremantle Highway car transporter ship in the North Sea, website electrek spoke to the Dutch coastguard and reported that – in contrast to widespread finger-pointing at EVs – the cause of the fire was unknown.

One month later, German trade publication Automobilwoche went further and reported that the fire had not been caused by exploding electric cars, “contrary to much media speculation”.

In a post on LinkedIn summarising its reporting, the outlet says: “The investigations indicate that the electric cars on board were not the cause of the fire, contrary to much media speculation.”

In July 2023, an EU-funded research programme on reducing the risk of fires on ships, known as LASH FIRE, released information on “facts and myths about fires in battery electric vehicles”.

There are fewer fires in EVs than in combustion engine cars, it says, adding that those fires that do occur in EVs do not burn more intensely or at higher temperatures than for combustion engines.

In summary, EVs are “not more hazardous” than conventional cars, the document says, but the risks they present are different. It explains:

“New technologies naturally raise a large interest in the public and as new energy carriers make their way into the market, some misconceptions will naturally also make their way to the public. BEVs are not more hazardous than internal combustion engine vehicles (ICEVs), but the risks of Li-ion batteries differ to those of conventional fuels.”

An August 2023 press release from the International Union of Marine Insurers comments on the Fremantle Highway fire and says: “to date, no fire onboard a ‘roro’ or pure car and truck carrier (PCTC) has been proven to have been caused by a factory-new EV”.

It reiterates the LASH FIRE findings and notes that while batteries exposed to fire can result in “thermal runaway”, which can be harder to put out, the resulting risks can be managed. It adds:

“Traditional fuels such as petrol and diesel are potentially extremely dangerous but we, as a maritime industry, have learnt to understand and mitigate the associated risks. Lithium-ion batteries are still relatively new but have already become a major part of everyday life. The maritime industry is still learning and needs to adapt to these new sets of risks and mitigate them accordingly.”

In another recent incident, social media users – and some media outlets – pointed the finger at EVs after a huge fire broke out in a car park at Luton airport in the UK.

Even after the local fire service “confirm[ed] the initial vehicle involved in the fire was a diesel car” and CCTV footage emerged of the car itself, showing it to be a 2014 diesel Range Rover, many social media users continued to insist that EVs must have been to blame.

Armchair experts argued that it is hard to get diesel to burn and that it must have been an electric hybrid, even though Range Rover did not sell hybrids in 2014. (An error-strewn 18 October comment by Daily Telegraph columnist Allison Pearson repeated this false claim.)

Meanwhile, the Daily Mail reported that there had been previous fires involving Range Rovers and Land Rovers. It said:

“The Range Rover fire which sparked last night’s Luton airport car park inferno comes six years after a Land Rover went up in flames at Liverpool’s Echo Arena’s car park. The blaze at Luton airport yesterday also comes six months after Land Rover recalled several models of the Range Rover and Range Rover Sport to address issues that could potentially lead to fires.”

FALSE: ‘Under Biden’s electric vehicle mandate, 40% of US auto jobs will disappear’

Another angle of attack on EVs is that the transition towards electrified transport will cause problems for the manufacturing industry in general and for its workers in particular.

In remarks reported by the Economist, for example, former US president Donald Trump said the shift to electric cars is a “transition to hell” that will destroy “your beautiful way of life”.

Yet, as a September 2023 article from CNN notes, the US car industry has announced more than $100bn of investment in the transition to EVs, creating “more than 100,000 American jobs”.

In further recent remarks, Trump falsely claimed that “under Biden’s electric vehicle mandate, 40% of US auto jobs will disappear”. FactCheck.org “found no support” for this claim.

A New York Times factcheck also says Trump’s claim “lacks evidence” – but it repeats the idea that “electric vehicles can be made with fewer workers than gasoline vehicles”.

An article for Heatmap challenges this argument, saying that, while it seems to be “conventional wisdom”, research uncovered for the article “suggested the opposite”. It says:

“Trump may be exaggerating, but the underlying idea, that electric vehicles require less labour to manufacture than internal combustion engine cars, is the conventional wisdom. It has been circulated for years by automakers, autoworkers, politicians, and journalists. EVs contain fewer parts, the thinking goes, so naturally they will require fewer workers.

“That logic seems obvious, which might be why it hasn’t received much scrutiny. But when I tried to find any research supporting it, what I found instead suggested the opposite. A number of analyses showed that electric vehicles could actually require more labour to build than gas-powered cars in the US, at least for the foreseeable future.”

A 2020 report from the Boston Consulting Group (BCG) supports Heatmap, stating:

“The common wisdom that BEVs are less labour intensive in assembly stages than traditional vehicles is inaccurate. In fact, the labour requirements for ­assembling BEVs and ICEVs are comparable.”

In its latest report on how to limit global warming to 1.5C, the International Energy Agency (IEA) says that a shift towards net-zero emissions would see 30m new clean energy jobs created by 2030 in industries including low-carbon power and electric vehicles.

These new jobs would outweigh losses in coal, oil and gas extraction, as well as in the production of combustion-engine vehicles, by two to one overall, the IEA says. In the car industry specifically, the IEA suggests new jobs making EVs and batteries would roughly balance losses elsewhere.

Evidence from the UK suggests the shift to EVs could create 80,000-100,000 new jobs. However, these jobs are contingent on attracting manufacturers to make EVs and their batteries in the UK.

In a May 2023 report, government advisory body the CCC highlights the conditionality on these jobs:

“The UK has taken steps to capture market shares and some car manufacturers are investing in electric vehicle manufacturing in the UK. However, there have been challenges and there is a risk manufacturing will find more favourable conditions elsewhere. Subsidies in places such as the US and the EU are likely to attract investment and secure jobs outside of the UK.”

What is not in doubt is that the transition to electrified transport will be disruptive. The rise of Chinese manufacturers of EVs – and the batteries that power them – is a case in point.

Another BCG report, looking at the car industry in Europe out to 2030, notes that it expects the shift to EVs to have a “minor net impact” on job numbers overall. However, it adds that this “obscures massive changes” in the type and distribution of jobs in the sector.

In the US, the argument over EV jobs has coincided with – and is partially tied up in – a dispute between carmakers and unionised labour. In October 2023, the Financial Times reported:

“General Motors has agreed to include battery manufacturing plants in its overarching contract with the United Auto Workers [UAW], the union said, meeting a crucial demand for employees anxious over the industry’s shift to electric vehicles…The UAW has been pushing for higher wages and other concessions in a new contract…It has also sought to extend contract protections at the plants that will provide many of the batteries for a wave of EVs hitting the market in the next several years.”

FALSE: ‘Electric car revolution at crisis point’ due to ‘charging point shortage’

In early 2023, the Daily Mail reported that the “electric car revolution [is] at crisis point” in the UK due to a “charging point shortage”. Around the same time, the Times said a “lack of [charging] infrastructure” was “threatening the EV revolution”.

Since then, UK EV sales have continued to surge, growing 36% year-on-year in the first nine months of 2023. Global EV sales grew 40% in the first half of the year.

While the headlines are clearly false, it is clear that a rapid transition to EVs will require a similarly fast rollout of charging infrastructure – and there are bound to be teething troubles along the way.

In its sixth assessment report, the IPCC emphasises the need for investment in charging infrastructure and the electricity networks it connects too. It says with high confidence:

“The continued growth of electromobility for land transport would require investments in electric charging and related grid infrastructure.”

Returning to the case of the UK, the number of public charging points reached the milestone of 50,000 in early October 2023, according to charging services provider Zapmap. It said this represented year-on-year growth of 43%, with the number of “ultra-rapid” chargers up 68%.

Zapmap says the number of public chargers will reach 100,000 in 2025, if current rates of installation continue, against a government target of 300,000 by 2030.

@zap map on X: We're very pleased to confirm that the UK has hit a major milestone of 50,000 charge points.

While the number of chargers remains highest in London, recent growth has largely been outside the capital city, according to figures released in July 2023 by the Department for Transport.

In August 2023, the Association for Renewable Energy and Clean Technology (REA) and several other groups wrote to UK transport minister Jesse Norman, calling for charge points to be given priority in the queue for connections to the electricity grid, among other changes. They wrote:

“By adopting the recommendations in this report, the government can achieve its target of reaching 300,000 charge points by 2030, creating new jobs and driving economic growth.”

Nevertheless, a July 2023 editorial in the Times said: “The rollout of charging infrastructure is going too slowly.”

That month, the Financial Times reported industry fears the shift to EVs was being “held up” by the “painfully slow” process for connecting new chargers to the grid.

Looking at the global picture, some $1tn of investment in the charging network is needed over the next three decades, according to BloombergNEF. It explains:

“Over $1tn in cumulative investment in EV charging infrastructure is required globally over this period [to 2050]…The required charger investment is still small compared to overall auto sales. For example, China requires $453bn of cumulative investment in charging infrastructure to 2040, compared to automotive sales revenue from domestic car sales and exports of $750bn in 2022 alone.”

The number of public charge points more than doubled in several European countries over the past year, according to figures assembled by consultancy Cornwall Insight. Growth in the UK was in the middle of the pack, at 57%, ahead of Germany (35%) but behind Poland (81%).

In its 2023 global EV outlook, the IEA notes that most charging is done at home, but that public infrastructure remains important. It says:

“While most of the charging demand is currently met by home-charging, publicly accessible chargers are increasingly needed in order to provide the same level of convenience and accessibility as for refuelling conventional vehicles.”

In a launch presentation for the report, the agency says that charging infrastructure “kept pace” with the growth of EVs in 2022, with the stock of charging stations rising by 55%.

ragout-4_iea

There were 2.7m public charging points worldwide at the end of 2022, the IEA says. It adds that 60% of slow charging points were added in 2022 – and almost 90% of fast chargers – were in China.

FALSE: ‘Britain’s creaking power grid cannot cope with charging electric cars’

During the summer of 2023, the Sun newspaper made a series of false arguments against EVs as part of its “give us a brake” campaign “to protect drivers from a rush to net-zero”.

In one August 2023 article, for example, the Sun claimed falsely that “Britain’s creaking power grid cannot cope with charging electric cars”. This is described as a “myth” by National Grid, the company that owns and operates the UK’s electricity network.

A January 2023 comment for the Sun by the climate-sceptic motoring lobbyist Howard Cox also claimed that the UK’s grid would have problems meeting demand for EVs. He wrote:

“Unless the capacity of the national grid is expanded by tens of gigawatts, there will be insufficient power to meet the proposed growth in battery-powered electric vehicle ownership and maintain anything like our current treasured freedom of motoring movement.”

While the specifics have shifted, the spirit of the Sun’s false claims recall a series of 2017 articles – which Carbon Brief factchecked at the time – that incorrectly and implausibly said the UK would need 20 new nuclear plants to meet the demand for electricity from EVs.

(The Sunday Times later removed this wildly overstated figure, issuing a print correction that acknowledged a “significant miscalculation based on a confusion of energy and power”. The false claim remains, more than six years later, in the article’s web address.)

Of course, there is no question that the transition from combustion engine cars to EVs will dramatically reconfigure global energy demand – as well as cutting emissions. It will cut demand for oil, reducing imports and energy security in countries such as the UK and China.

At the same time, EVs will become a significant new source of electricity demand. In its latest report, the IPCC states: “Decarbonising the transport sector will require significant growth in low-carbon electricity to power EVs.”

(The IPCC notes that decarbonising transport with “energy-intensive fuels, such as hydrogen, ammonia and synthetic fuels” would require even larger increases in electricity generation.)

EVs already used an estimated 110 terawatt hours (TWh) of electricity in 2022, according to the IEA, equivalent to the entire annual consumption of the Netherlands – or 0.5% of global demand.

This could rise tenfold, to 1,150TWh in 2030, if countries meet their climate pledges, the IEA estimates, equivalent to nearly 4% of global electricity demand. These EVs would cut global oil use by nearly 6m barrels per day, around 6% of current demand.

According to BloombergNEF, EVs will add 12-14% to global electricity demand in 2050.

In the UK, EVs would increase electricity demand by up to 38TWh in 2030 and 88TWh in 2035, according to the latest scenarios from the National Grid Electricity System Operator (ESO). This would cut cars’ demand for petrol and diesel in 2030 to 27-45% below current levels.

In addition to raising annual demand for electricity, there have also been fears that uncontrolled EV charging could increase the peak load on electricity grids.

UK newspapers such as the Daily Telegraph were once again quick to highlight these supposedly insurmountable problems, with a 2017 article saying plans to ban petrol and diesel car sales by 2040 were “unravel[ling] as 10 new power stations needed to cope with electric revolution”.

Once again, however, the company that actually runs the UK’s electricity network sees things differently. National Grid ESO says EVs could, in fact, support the network by storing excess generation from renewable sources and “giv[ing] [it] back to the grid in times of high demand”.

It says the country’s grid could “capably handle” an overnight switch to EVs, thanks to reductions in peak demand over the past two decade:

“Do the electricity grid’s wires have enough capacity for charging EVs? The simple answer is yes. The highest peak electricity demand in the UK in recent years was 62GW [gigawatts] in 2002. Since then, the nation’s peak demand has fallen by roughly 16% due to improvements in energy efficiency. Even if we all switched to EVs overnight, we estimate demand would only increase by around 10%. So we’d still be using less power as a nation than we did in 2002, and this is well within the range the grid can capably handle.”

The firm adds that it is, nevertheless, working with electricity distribution companies, government and others to ensure that “the wires, the connections to charge points” are in place to support EVs.

The IPCC says EVs “provide several opportunities for supporting electricity grids if appropriately integrated”, whereas they could “negatively affect the grid” if there is a lack of integration. It points to the use of “smart-charging” – where EVs are mostly charged during periods of low demand – which it says can cut the impact on peak electricity demand by 60%.

FALSE: ‘How your super heavy EV produces MORE pollution than petrol and diesel cars’

A July 2023 article from the Sun claimed falsely that EVs “actually end up producing MORE pollution than petrol and diesel motors”.

The article’s headline statement is false because it is framed very broadly, implying that EVs produce more “pollution” in general than combustion engine cars.

In fact, although it mistakenly refers to “milligrammes of carbon dioxide per kilometre from [an EV’s] four new tyres”, the article focuses more specifically on fine particulates (PM2.5) from tyre wear.

Even on this narrower point, the article is at best incomplete. Tyre wear is only one source of particulate matter from vehicles, along with exhaust emissions, brake wear and road abrasion.

In contrast to the impression created by the Sun article, the UK government stated unequivocally that the shift to EVs would have the co-benefit of “cleaner air”.

ragout-3_air_quality_benefits

The government document, published in early 2023, contradicts earlier statements from then-UK environment secretary George Eustice. Giving evidence to MPs in 2022, he raised questions over the air quality impact of shifting to EVs, saying:

“The unknown thing at the moment is how far switching from diesel and petrol to electric vehicles will get us. There is scepticism. Some say that just wear and tear on the roads and the fact that these vehicles are heavier means that the gains may be less than some people hope, but it is slightly unknown at the moment.”

The 2023 document notes that EVs have “no exhaust emissions of particulate matter (PM) or NOx [nitrogen oxides, which are emitted by petrol and diesel engines and which contribute to poor air quality”. It puts the net economic benefits of cleaner air from EVs at £1bn in present value terms.

The document refers to a report from the government’s air quality expert group and says that the non-exhaust emissions of EVs compared with conventional cars are assumed to be equal.

The expert group says that EVs “should” have lower brake wear emissions due to using “regenerative braking” rather than brake pads, but adds that tyre and road wear emissions increase with vehicle weight. The “net balance” between these effects “remains unquantified”.

The Sun article reports findings from independent testing firm Emissions Analytics that EVs are, on average, heavier than their combustion-engine equivalents, resulting in “20% more pollution”.

Motoring organisation RAC moved to quickly “set the record straight” over Eustice’s remarks, commissioning a brief report from Dr Euan McTurk, a consultant battery electrochemist.

McTurk also notes reduced brake wear in EVs, pointing to the experience of a taxi firm in Dundee, among others. Summarising McTurk’s conclusions on tyre wear, the RAC states: “[EV] tyre wear is similar for the non-driven wheels and only slightly worse for driven wheels.”

While the Sun article presented a false and misleading picture of the pollution impacts of EVs, it is the case that they currently tend to be heavier than equivalent combustion-engine cars.

Along with the much broader shift in consumer preferences towards larger, heavier SUVs, this does present problems for transport infrastructure.

An August 2023 article in the Guardian reported on SUVs being too large to fit in car parking spaces, a phenomenon it referred to as “autobesity”:

“More than 150 car models are now too big to fit in average car parking spaces, according to analysis conducted by Which?. While the size of the standard parking bay has remained static for decades, cars have been growing longer and wider in a phenomenon known as ‘autobesity’…All three of the widest cars are sports utility vehicles (SUVs).”

Other newspapers have chosen to focus their reporting on EVs, with an April 2023 article in the Daily Telegraph saying: “Car parks could collapse under the weight of electric cars.” Another Daily Telegraph  article was titled: “Sheer weight of electric vehicles could sink our bridges.”

ragout-2_the_Sunday_Telegraph

In June 2023, US factchecking site Politifact faulted claims by Republican presidential hopeful Nikki Haley, who had said: “Electric vehicles are so heavy that our roads and bridges aren’t capable of handling that.” The site concluded:

“Electric vehicles generally weigh more than gasoline-powered cars…But infrastructure experts said that by far, more damage to roads and bridges is caused by weightier vehicles such as semitrucks [articulated lorries].”

Similarly, the claim in a frontpage Daily Telegraph story that EVs cause “double” the pothole damage of petrol cars, was branded “rubbish” by TU Eindhoven’s Auke Hoekstra.

Hoekstra also points to the “disproportionate impact” of the heaviest vehicles, such as trucks and vans. He goes on to argue that batteries are getting twice as light per unit of capacity per decade, meaning that: “By the time most vehicles sold will be EVs…they will NOT be heavier.”

(The Daily Telegraph article cites “analysis led by the University of Leeds”, however, the university’s press office notes that its research does not say anything about potholes.)

Analysis: China’s new carbon metric leaves Germany-sized gap in its emissions

Published

on

A major change in the way that China measures its core climate goal has effectively halved the growth in the country’s carbon dioxide (CO2) emissions over the past five years.

The revised measure of “carbon intensity”, the amount of CO2 per unit of economic output, implies that China’s emissions have only gone up by 7% from 2020-2025.

This is just half of the 14% rise indicated by previous official statistics.

On paper, the revision creates a gap of 700m tonnes of CO2 (MtCO2) per year, equivalent to the total emissions of Germany or South Korea.

While China has never officially defined how it measures carbon intensity, it has now made what appears to be a retrospective change, with the effect of making targets easier to meet.

The shift means that China officially came close to meeting its carbon-intensity target for 2020-2025, whereas official statistics had previously pointed towards falling well short.

The new definition of carbon intensity has not been made public, but plausible approaches to calculating the metric do not seem to be sufficient to explain the Germany-sized gap.

The apparent gaps or inconsistencies in China’s new carbon accounting also mean that China could meet its international climate pledges for 2030, even if its emissions go up, whereas the previous measure would have required them to fall.

This article explains how the metric appears to have shifted, what changes might potentially explain the revision and what the revised measure implies for China’s climate goals.

Measuring carbon intensity

Reducing carbon intensity – CO2 emissions per unit of GDP – has been China’s key climate commitment since the Copenhagen climate conference in 2009.

At that time, the country pledged to cut its carbon intensity to 48% below 2005 levels by 2020. This was followed up by a 2030 target of a 60-65% reduction, announced in 2014, which was then upgraded to more than 65% in 2021.

Since carbon intensity was made a key progress indicator in China’s 14th five-year plan for 2021-25, the country has reported reductions in carbon intensity every year in its statistical communique, issued at the end of February.

Neither China’s international climate pledges (its nationally determined contributions, NDCs) nor other official documents have ever set out a definition of carbon intensity, despite it being a cornerstone of the country’s climate commitments.

However, until this year, it was possible to closely reproduce the reported numbers, based on a straightforward interpretation of what carbon intensity means.

But the types of emissions that are included in the carbon-intensity metric have now changed.

Previously, it was possible to reproduce the reported carbon-intensity data by combining official GDP data with estimates of emissions from the use of fossil fuels. The latter could be estimated based on the officially reported consumption of coal, oil and gas, multiplied by China’s official emissions factors for the CO2 per unit of energy from each fuel.

The previous carbon-intensity measure apparently included emissions from the use of fossil fuels to generate energy, as well as their use as chemical feedstocks, so-called “non-energy uses”. However, it did not include non-fossil fuel CO2 emissions from industrial processes, such as the production of cement, as shown by the “old scope” in the figure below left.

Chart showing that China has changed the scope of its carbon-intensity metric
Old and new scopes of China’s CO2 emission reporting from fossil-fuel use and industrial processes. Source: Analysis for Carbon Brief by Lauri Myllyvirta. See “about the data” for further details.

Based on the annually reported progress against this old scope, China’s carbon intensity had fallen by a total of 12.4% from 2020-2025.

This was well short of the 18% target set for these years under the 14th five-year plan.

In September 2025, Huang Runqiu, head of the Ministry of Ecology and Environment, acknowledged this gap, saying that meeting China’s carbon-intensity targets had become “more challenging” due to the effects of the Covid-19 pandemic and trade tensions.

Yet the 15th five-year plan, published in March 2026, reported that China had cut its carbon intensity by 17.7% over the same period – just shy of the 18% target.

As such, it is clear that there has been a major shift in the way that China measures its carbon intensity, specifically in terms of which types of emissions are included.

Moreover, the revised numbers imply that – rather than missing it by a large margin – China officially came close to meeting its carbon-intensity target for the 14th five-year plan.

A footnote in China’s latest statistical communique offers a brief description of carbon intensity as relating to the CO2 emissions from “energy activities and industrial production”.

This indicates that the carbon-intensity calculation now includes industrial process emissions and excludes non-energy uses of fossil fuels, shown by the “new scope” in the figure above.

In comments sought by Carbon Brief, Ryna Cui, associate research professor at the University of Maryland School of Public Policy, who was not involved in the analysis, agrees that the changes to the carbon-intensity methodology are “unclear”. However, she notes that “limited data” makes it challenging to fully verify the nature and impact of the changes.

The revision mirrors a recent change made to the way that China measures its “energy intensity”, the energy use per unit of economic output. In 2024, energy intensity was changed to exclude non-energy use of fossil fuels and energy use from non-fossil fuels.

This exclusion also created a major incentive for expanding the chemical industry and the non-energy use of fossil fuels.

As for the change in carbon-intensity metric, this follows the highly energy-intensive pattern of economic growth during and after the Covid-19 pandemic and China’s “zero-Covid” policy.

Germany-sized gap

The shift in the way that China is measuring its carbon intensity has implications for estimates of the country’s emissions, which are only reported officially some years later.

Changes in carbon intensity and GDP are reported far more quickly – and can be used to estimate changes in China’s CO2 emissions.

China’s total emissions from energy and industrial processes were 11.2bn tonnes of CO2 (GtCO2) in 2020. Based on the originally reported changes in carbon intensity and GDP, its fossil-fuel CO2 emissions had grown 14% by 2024, an increase of 1,430m tonnes (MtCO2).

In contrast, the newly reported carbon-intensity figures imply that China’s CO2 emissions only grew by 7% between 2020 and 2025, up just 690MtCO2, as shown by the figure below.

The gap between these figures amounts to 730m tonnes of CO2 (MtCO2), equivalent to the annual emissions of Germany or South Korea.

Chart showing that China's new carbon metric leaves Germany-sized gap in emissions

On paper, therefore, the change in the carbon-intensity metric effectively halves the rate of growth in China’s CO2 emissions over the past five years.

Decoding the new carbon-intensity methodology

The change in the carbon-intensity metric could have other significant implications, explored below, making it important to understand how it is being calculated.

Yet, while there are some indications of what the new approach entails, these changes do not seem to account for the magnitude of the revision.

The new scope includes industrial-process emissions. One of the largest sources of these emissions, the cement industry, has been contracting due to a slowdown in real estate and infrastructure construction.

This reduction in emissions is one reason why China’s carbon intensity has improved more quickly under the new scope than under the old one.

In addition, the new scope excludes non-energy use of fossil fuels – largely relating to the chemicals industry – where there has been rapid growth over the past five years.

This is another factor in carbon intensity improving faster under the new scope.

Indeed, China’s chemicals industry drove more than half of the growth in its total fossil-fuel use in the past five years, including 40% of coal use and all of oil use. As a result, non-energy use reached 13% of the total consumption of fossil fuels in 2025, up from 7% in 2020, after growing at an average annual rate of 13%.

The figure below illustrates the impact of these changes in scope. It shows the change in China’s emissions from 2020-2025 due to the use of fossil fuels for energy, its industrial-process emissions and non-energy use of fossil fuels.

The first few rows show changes based on the consumption of fossil fuels overall, amounting to a combined 1,430MtCO2 rise in emissions.

This compares with the 690MtCO2 rise implied by the new carbon-intensity metric, leaving that Germany-sized 730MtcO2 gap in emissions. The new scope explains some of this gap.

In terms of industrial processes, the 30% fall in cement production could account for a 300MtCO2 fall in China’s CO2 emissions. In addition, the amount of carbon stored in products, such as plastics, asphalt and rubber, could account for an estimated 100MtCO2 fall in emissions.

On the other hand, emissions from the incineration of plastics increased by an estimated 40% and from metals industry processes by 10%, with aluminium production having expanded by 21%. Together, these would have increased emissions by an estimated 60MtCO2.

In total, the changes in emissions from fossil-fuel use, industrial processes, carbon retained in products and waste incineration add up to a combined 1,070MtCO2 rise from 2020-2025, shown in the penultimate row of the figure below.

Again, this revised total – based on the change in scope of the carbon-intensity metric – goes some way to explaining the Germany-sized gap in China’s CO2 emissions.

However, the new carbon-intensity figures imply that China’s CO2 emissions only increased by 690MtCO2, as shown in the final row of the figure below. This leaves a residual gap of around 380MtCO2, which does not appear to be accounted for by the data available.

Chart decoding China's new carbon-intensity metric

One way to make the numbers add up would be to assume that the amount of carbon embedded in chemical-industry products has increased by the equivalent of 500MtCO2.

However, the reported output of major chemical-industry products cannot account for this level of embedded carbon. The figure below shows that the increase in output of major chemical products only explains around a 110MtCO2 increase in retained carbon.

Much of the increase in the production of plastics was cancelled out by a contraction in the use of bitumen for asphalt, due to lower road-building activity.

Chart showing that a growing number of carbon is being stored in manufactured products
The amount of carbon retained in products from 2005-2025, MtCO2. Source: Analysis for Carbon Brief by Lauri Myllyvirta. See “about the data” for further details.

Furthermore, the 14th five-year plan for 2021-25 had a target of raising the share of waste incineration to 65% of urban residential waste treatment capacity, up from 45% in 2020.

So, while plastics production did go up, resulting in increased amounts of retained carbon, a larger share of this retained carbon was being incinerated, meaning its carbon would quickly be released back into the atmosphere.

One reason why carbon retained in products has grown more slowly than the amount of fossil fuels used in chemicals production is that the fastest growth has been in the coal-based chemicals industry.

Coal-based processes have a much lower conversion efficiency than oil- and gas-based production, with process emissions that are typically multiple times as high.

For example, these emissions are 10 times as high for the production of olefins – a key plastics feedstock – from coal as compared with oil or gas. The process is reported to require 3.75 tonnes of standard coal per tonne of product. This implies that only 30% of the carbon in the coal is retained in the product, with the other 70% being emitted in the process.

There are also chemical processes that use fossil fuels as a feedstock, but where the end product does not contain carbon. One example is ammonia, a key building block for fertiliser, where production grew by 52% from 2020 to 2025.

Neither the change in scope of the carbon-intensity calculation, nor the change in the amount of carbon retained in products, is sufficient to explain the size of the revision in the newly reported numbers. There must be another explanation.

There are two options. Either the new scope broadly aligns with what is outlined above, but also excludes a subset of the CO2 emissions. Or the scope does not exclude any of the CO2, but there are gaps in the monitoring of some energy or industrial-process emissions.

Either explanation would mean that China is not accounting for some of its CO2 emissions. It would also mean that the improvement in carbon intensity for 2020-2025 is over-reported.

China’s latest officially reported emissions inventories reinforce the second of the two options above, namely, that there are gaps in emissions reporting from the chemical industry.

From 2018 to 2021, the latest year for which China has reported on its emissions, the CO2 output of chemical-industry processes only increased by 13%. Over the same period, non-energy use of fossil fuels increased by 29%, according to data reported to the International Energy Agency by the Chinese government.

One factor in these apparent gaps could be that China’s National Bureau of Statistics (NBS) is required to publish data on carbon intensity very quickly, since it is a key indicator in the country’s five-year plans.

On the other hand, detailed greenhouse gas emissions inventories and energy statistics are only published years later, by the environment ministry and NBS, respectively.

What the change means for China’s targets

The change in the definition of carbon intensity has the effect of weakening China’s climate targets and introducing more uncertainty into tracking progress.

On the basis of China’s new numbers, it will require less effort to hit the 2030 target for a 65% reduction in carbon intensity on 2005 levels, as per China’s Paris pledge.

This target can now be met even if CO2 emissions go up between 2025 and 2030, whereas the previous metric would have required a reduction.

It will also require less effort to hit the 17% target in the 15th five-year plan.

The apparent gaps in the CO2 emissions numbers for 2025 could affect the delivery of China’s other key climate pledges, such as the commitment to peak CO2 emissions before 2030. They could also allow the chemical industry’s CO2 emissions to continue climbing rapidly, while still officially meeting the 2030 goals for CO2 intensity.

Moreover, the apparent gaps or inconsistencies in China’s new carbon accounting also mean that China would be able to officially meet its target to peak its CO2 emissions by 2030, even if its overall CO2 emissions do not actually reach a peak.

The apparent gaps could also affect the delivery of China’s newer target to cut its greenhouse gas emissions to 7-10% below peak levels by 2035 and beyond.

Nevertheless, researchers and analysts can still monitor progress by calculating China’s CO2 emissions independently.

China’s reporting on fossil-fuel consumption, the output of plastics and other carbon-containing products, as well as manufacturing of commodities with substantial process emissions, provides a basis for tracking emissions under the new scope.

While under the UN’s climate framework China is free to use any definition it wants to meet its own nationally determined climate pledges, retrospective changes to methodology or inconsistent accounting could erode the value of the country’s commitments.

Moreover, it will, ultimately, have to close any gaps in its emissions data and reporting, under the transparency rules of the Paris Agreement.

China’s next transparency report to the UN, due by the end of this year, should also provide more clarity on the methodology and data underlying the revised numbers.

This underscores the importance of monitoring, reporting and verification for industrial process emissions. “Mass balances” based on fossil-fuel consumption and product output could be used as a check on CO2 emissions reporting. Finally, China’s emissions data could also be made more granular and clearly defined.

Carbon Brief has approached the National Bureau of Statistics and Ministry of Ecology and Environment for comment.

The University of Maryland’s Cui tells Carbon Brief that in general, China’s climate goals are “improv[ing]” in terms of their coverage and scope. However, she adds:

“The issue is…the ambiguity and inconsistency in the coverage, definition and method between target setting and progress tracking, which can lead to large uncertainties and room for manipulation. It highlights the importance of transparency in national climate targets, following the UNFCCC’s international transparency framework, which should also be applied as best practices for domestic targets.”

About the data

The calculations in this analysis are based on China’s total coal, oil and gas consumption from energy statistical yearbooks covering the years until 2023, with data for 2024 and 2025 taken from the latest statistical communiques.

“Originally reported” CO2 emissions were back-calculated from carbon-intensity reductions and GDP growth given in annual statistical communiques. The revised emissions for 2020, 2024 and 2025 are similarly back-calculated from the reductions in carbon intensity from 2020 to 2025 and from 2024 to 2025, as reported in the 15th five-year plan outline and the 2025 statistical communique, respectively, combined with annually reported GDP growth.

Cement process emissions up to 2024 are from Robbie Andrews’ estimates, scaled to 2025 based on year-on-year change in total cement output.

Process emissions from the metals industry are based on calculating emissions for aluminium, silicon, lead, zinc and crude steel from the bottom-up, using industrial output data and IPCC default emission factors scaled to the reported total in 2021. For steel, the calculations are based on typical quicklime use in basic-oxygen and electric-arc furnaces.

Emissions from the incineration of plastics are based on a peer-reviewed estimate of plastics incineration in 2022, combined with growth rates in the overall power generation from waste-to-energy plants. The analysis assumes that the share of plastics in the energy content of the incinerated waste stayed constant over this period, which is a conservative assumption given the rapid rise in plastics production.

Total non-energy use of fossil fuels in 2020, 2024 and 2025 is available from an NEA data release, with data for 2021-2023 found in the China energy statistical yearbook 2025.

The mix of coal, oil and gas within non-energy use is based on the energy statistical yearbook data up to 2023, with the increase in coal in 2024 and 2025 based on Wind Financial Terminal data on coal consumption in the chemical industry. Gas use, which is relatively minor, is assumed to have grown on trend and oil is calculated as the residual.

Primary plastics, rubber, and urea output data are from NBS industrial statistics. The production of solvents, lubricants and waxes, as well as the use of bitumen in construction, is from energy statistical yearbooks. The analysis assumes no change in output from 2023 to 2025, given the lack of clear trends.

Revealed: Floods have forced at least 67 closures at NHS hospitals since 2021

Published

on

At least 67 NHS hospital wards, departments and other sites across the UK have been forced to temporarily close or relocate due to weather-related flooding over the past five years, a Carbon Brief investigation reveals.

Maternity centres, surgical theatres, a neonatal intensive-care unit and even entire hospital buildings have been disrupted by heavy rainfall or encroaching floodwaters.

Carbon Brief submitted freedom-of-information (FOI) requests to 162 NHS trusts, which show that while many flood-related shutdowns were brief, some lasted for weeks or months.

In total, 148 trusts responded to these requests with reports of 67 flood-related shutdowns, giving detailed data for 30 incidents that resulted in a total of 3,000 days of closures.

Reports of flooding at NHS sites have been on the rise, according to NHS England data.

This comes as the UK experiences wetter winters, with periods of extreme rainfall that are increasingly linked to human-caused climate change.

These floods can exacerbate existing problems in a healthcare system that is already struggling with insufficient funding, old hospital buildings and a backlog of maintenance work.

Indeed, while there have been efforts to make UK hospitals more resilient to extreme weather, one expert tells Carbon Brief that such measures are difficult to implement when these institutions are struggling to keep their “heads above water”.

Rising floods

Floods pose a threat to people’s health, but they also threaten the UK’s healthcare infrastructure. Water can enter hospitals, paralyse ambulance services and damage equipment, placing strain on an already stretched NHS.

NHS records show that the number of flood incidents “caused by external weather events” in facilities across England has doubled since 2021, reaching nearly 400 in 2024-25.

Equivalent data is not available for Scotland, Wales and Northern Ireland, although there have been reports of floods disrupting services across the whole UK.

As global temperatures rise and the atmosphere holds more moisture, UK winters are getting wetter. Attribution studies show climate change has increased the severity of recent rainfall and flooding events – including Storm Eunice in 2022 and Storm Babet in 2023.

There is also a risk of increased flooding when heavy rain hits after periods of intense drought, of the kind seen in recent years.

Environment Agency modelling suggests that a rising share of medical facilities in England will be at risk of flooding due to climate change. It says the share of sites at risk will increase from a quarter in 2024 to a third by the middle of the century.

Despite this apparent threat facing the UK’s healthcare system, there is limited information about the extent to which these floods are already disrupting NHS services.

Closed services

To build a fuller picture of NHS-wide flooding, Carbon Brief sent FOI requests to 162 trusts and health boards – the organisations in charge of health services – across England, Scotland, Wales and Northern Ireland.

They were asked for details of wards, departments or services that had been temporarily or permanently closed due to weather-related flooding, such as river floods or heavy rainfall, between 2021-22 and the start of 2026.

In total, 148 of these bodies responded with details of 67 incidents in which weather-related floods have triggered closures. The map below shows where these incidents were located, from hospital wards in Scotland to an eye unit on the south coast of England.

The 67 flooding-related disruptions reported by NHS trusts and health boards is likely an underestimate. Many trusts told Carbon Brief they did not record such detailed information or that collating it would be too time-consuming.

Nevertheless, the results provide an insight into the kind of risks facing NHS services as weather gets more extreme.

Among the closures were 13 accident and emergency (A&E) departments, urgent treatment centres and minor injuries units. There were also 10 hospital wards, 10 surgical theatres, five maternity units and a neonatal intensive-care unit affected by flooding.

Many trusts did not provide information about how long each closure lasted. However, the 30 incidents where timespans were provided add up to the equivalent of more than 3,000 days – or eight years – of closures across NHS sites.

The infographic below provides a snapshot of some notable closures from the dataset.

The entire Buckland Hospital site in Dover closed for two days in 2025 amid “exceptional rainfall” and flash floods. People seeking radiology, maternity and urgent-care services were told not to visit over the weekend and various clinical services were delayed or cancelled.

The NHS declared a “major incident” in 2021 when flood waters “caused power outages impacting multiple areas” at Whipps Cross Hospital in north-east London – including its maternity service – for four days. Neighbouring hospitals also flooded.

Some closures lasted far longer. In Stroud General Hospital, a surgical theatre was closed for two weeks and an X-ray facility for around two months after storm water overflowed into the building in 2023.

Several NHS trusts stressed that the flooding incidents they reported were localised – often resulting from roof leaks exacerbated by heavy rain – and resulted in minimal disruption. Sometimes, as with a cardiology suite in Cannock Chase Hospital, the service was moved and the trust says patient care was not disrupted.

However, the responses also showed the breadth of damage such events can cause, including rainwater “pouring onto expensive equipment” and floods triggering the long-term relocation of services.

For example, Orchard Cottage, a site that provided care for adults with learning disabilities in Derbyshire, experienced major flooding during Storm Babet in 2023 and was permanently shut down as a result.

Adaptation needs

The UK Health Alliance on Climate Change, a group of UK health organisations, concluded in a report in 2025 that, with flood risks projected to grow, there is an “urgent need for adaptation measures” across the nation’s healthcare facilities.

Government advisors at the Climate Change Committee have highlighted the need for flood resilience in UK hospitals, including flood barriers, waterproofed electricals and built-in redundancy for critical areas, such as theatres, labs and IT equipment.

There have been various measures at both government and NHS level intended to improve the resilience of medical facilities to climate-related hazards.

The UK’s national adaptation programme sets out expectations for NHS England to “adapt NHS infrastructure to extreme weather events”. All trusts must have “green plans” in place, which require climate change to be factored into infrastructure decisions, for example, through the creation of drainage systems or green spaces.

Yet, as it stands, three-quarters of UK doctors say their workplaces are not prepared for the impact of extreme weather and nearly half of healthcare workers report that extreme weather has disrupted NHS services in the past five years.

Many hospitals have outdated infrastructure – often predating the founding of the NHS – which was not designed to cope with climate change. Prof Hugh Montgomery, chair of intensive-care medicine at University College London, tells Carbon Brief:

“The hospitals themselves weren’t built for this weather any more than anything else is really – and of course it’s going to get worse, in an exponential function.”

Many of the FOI responses provided to Carbon Brief identified specific building defects, such as roof leaks, which led to the flooding incidents during periods of heavy rainfall. There is a huge – and growing – backlog of maintenance work at NHS hospitals that was estimated in 2024-25 to need repairs costing £15.9bn.

Chris Naylor, a senior fellow at the King’s Fund, a thinktank focusing on health policy, tells Carbon Brief:

“Dealing with some of the backlog maintenance would probably help with climate adaptation as well, because of leaky roofs and all the rest of it. But we do also need to be thinking specifically about climate adaptation within the NHS and making sure there is funding for that.”

Montgomery points out that with trusts “mostly bankrupt” and most hospitals running a deficit, the question remains how to fund such interventions. “They’re struggling to keep their heads above water and they’re losing money,” he says.

Dr Mark Harber, a consultant nephrologist and special adviser on climate change at the Royal College of Physicians, tells Carbon Brief that hospitals at least need to make plans for extreme weather. This is particularly important for patients in need of time-dependent and life-saving treatments, such as kidney dialysis and chemotherapy.

Harber notes that hospitals, supply chains and transport could all be disrupted by floods:

“You have to have plans in place to deal with that, even if the NHS can’t deal with the flooding risk per se.”

Carbon Brief asked NHS England – which is responsible for the majority of the trusts that reported flooding disruption – for comment, but had not received a response at the time of publication.

Methodology

The list of incidents reported by trusts can be viewed here.

Carbon Brief sent FOI requests to 120 English NHS trusts that have reported any incidents of flooding since 2021 in NHS England’s Estates Returns Information Collection (ERIC) dataset. This covers around 60% of all English NHS trusts.

Carbon Brief also filed FOI requests with all 42 of the health boards and trusts in Scotland, Wales and Northern Ireland, which are equivalent to English NHS trusts.

All trusts and health boards were asked for details of wards, departments or services that have been temporarily or permanently closed due to weather-related flooding, such as river flooding or heavy rainfall.

This matches the wording used to describe a flooding event in the ERIC system, which requires the reporting of all flood events “caused by external weather events” that trigger a risk assessment by staff. Such external events are distinct from floods caused by other issues that are not related to the weather, such as burst pipes.

In total, 14 trusts did not respond and many more said they did not hold the data requested. Some trusts provided data, but on further questioning stated that the data they provided covered all flooding events and it was not possible to say which were related to weather conditions. These cases have not been included in the final dataset.

Nature cannot be ignored by Europe’s next big budget

Published

on

Adeline Rochet is a programme manager for the Corporate Leaders Group Europe, a business coalition driving the transition to a sustainable, competitive, and resilient economy convened by the University of Cambridge Institute for Sustainability Leadership (CISL).

Europe’s economy depends on the natural world functioning as it should, but the effects of climate change risk undermining increasingly delicate ecosystems. Talks about the European Union’s next long-term budget miss this fact.

Climate-related losses in the EU have already reached €822 billion since 1980, with a quarter of that damage concentrated in just the past four years. Ecosystems are under increasing pressure: more than 80% of protected habitats are in poor condition, soils are degrading and water stress is rising across the continent.

The latest state of the climate report by the EU’s Earth monitoring service Copernicus confirms this worrying state of affairs: 95% of Europe experienced above-average temperatures in 2025.

Economic exposure to nature-related risk is also growing. Businesses, banks and insurers are beginning to reflect this in their risk assessments.

So, will the policymakers in charge of developing the European Union’s next big budget integrate this vision? We are in the midst of finding out.

    Every seven years, the EU must negotiate a new budget that will help fund priorities over a seven-year-long period. The current one, which runs out next year, is worth more than a trillion euros.

    Talks about the next multiannual financial framework (MFF) for 2028-2034 are now getting serious and the initial outline of this new budget shows it will focus on competitiveness, resilience and prosperity.

    But, as the European Parliament adopted its negotiating position for the crunch budget talks and EU member states shape their approach ahead of a Council meeting on May 26, it is clear that the positioning of nature within this framework is strategically underestimated.

    Why nature impacts economic growth 

    Back in 2022, France’s nuclear power output was severely affected when heatwaves drove up the temperature of the rivers used to cool atomic reactors, impacting other European countries too. This was particularly poor timing given the energy price crisis triggered earlier that year by Russia’s illegal invasion of Ukraine.

    Low river levels caused by drought have also heavily impacted economic activity and growth in countries like Germany, due to the negative effect on inland trade, while degraded fields in the Netherlands combined with heavy rainfall have ruined potato harvests.

    These examples show that we cannot detach the health of the European economy from the good functioning of nature.

    Nearly three-quarters of businesses in the eurozone rely directly on ecosystem services such as clean water, fertile soils and pollination. That dependency extends into the financial system, where around 75% of bank lending is exposed to companies dependent on these natural assets.

    They entirely underpin supply chains and financial stability across the European economy. If load-bearing ecosystems collapse, businesses not only face disruption in their own operations, but they will also be exposed to failures from suppliers and customers.

    This is not just a risk for individual companies, it is a threat for the whole system.

    A budget that looks greener than it is

    According to the latest proposals for the next MFF, a single 35% climate and environmental target will replace priorities that used to have distinct funding. As it stands, biodiversity has a 10% target, yet spending has struggled to reach even 8%, already showing how easily it is put to one side in practice.

    In the new framework, biodiversity is absorbed into a broader category with no separate tracking or visibility. Dedicated instruments are folded into larger funding envelopes, and nature-based investments are placed in direct and distorted competition with industrial projects.

    These are often faster to deploy and easier to measure, making them more attractive.

    Headline figures reinforce some appearance of ambition, with €587–635 billion allocated to climate and environmental objectives. But since these are aggregated numbers, they do not show how much will reach ecosystem conservation or restoration.

    Less visibility, weaker accountability

    Biodiversity funding also remains structurally fragile, with around 80% concentrated in agriculture policy rather than supported by a diversified investment strategy.

    This shift is structural: nature has been relegated from a defined priority to a mere discretionary allocation, and the governance model reinforces this dynamic.

    Greater reliance on National and Regional Partnership Plans (NRPPs) moves decision-making into national spending choices, where fiscal and domestic political pressure will likely mean long-term ecosystem investments struggle to compete with short-term economic demands.

    The current MFF paints a worrying picture of structural triple risk for nature: reduced visibility, increased competition for funding and weaker accountability.

    Nature is critical infrastructure

    It is a point worth reiterating: investment in nature offers clear economic returns. Healthy ecosystems drive resilience by reducing exposure to climate damage and supporting local economic activity.

    Public finance plays a decisive role in enabling these investments at scale, making budget design a question of risk management and capital allocation.

    Nature-based solutions already perform essential economic functions. They regulate water systems, restore carbon sinks, provide a buffer against extreme weather events and support agricultural productivity.

    These are characteristics of infrastructure. Energy systems, transport networks and digital capacity are treated as strategic investments because they underpin competitiveness.

    Natural systems play the exact same role, so why does the current budget plan not reflect this?

    The next EU budget will shape investment for the decade ahead. Its structure will determine how risks are managed and where capital flows. Nature cannot be erased in favour of competing short-term priorities.

    In the upcoming negotiations, European leaders still have the option to treat nature as a structural objective and a core asset, supporting Europe’s resilience and long-term competitiveness. But they must act now, before it’s too late.
