The UK’s greenhouse gas emissions fell by 3.6% in 2024 as coal use dropped to the lowest level since 1666, the year of the Great Fire of London, according to new Carbon Brief analysis.
Major contributions came from the closure of the UK’s last coal-fired power station in Nottinghamshire and one of its last blast furnaces at the Port Talbot steelworks in Wales.
Other factors include a nearly 40% rise in the number of electric vehicles (EVs) on the road, above-average temperatures and the UK’s electricity being the “cleanest ever” in 2024.
Carbon Brief’s analysis, based on preliminary government energy data, shows emissions fell to just 371m tonnes of carbon dioxide equivalent (MtCO2e) in 2024, the lowest level since 1872.
Other key findings from the analysis include:
- The UK’s emissions are now 54% below 1990 levels, while GDP has grown by 84%.
- About half of the drop in emissions in 2024 was due to a 54% reduction in UK coal demand, which fell to just 2m tonnes – the lowest level since 1666.
- Another third of the drop in 2024 emissions was due to falling demand for oil and gas, with the remainder down to ongoing reductions in non-CO2 greenhouse gases.
- UK coal demand fell at power stations (one-third of the reduction overall) and at industrial sites (two-thirds). In 2024, the UK closed its last coal-fired power station, as well as the final blast furnace at the Port Talbot steelworks. Furnaces at Scunthorpe paused operations. Both sites are due to convert to electric-arc furnaces that do not rely on coal.
- Oil demand fell 1.4% despite increased road traffic, largely due to the rise in the number of EVs. The UK’s 1.4m EVs, 0.8m plug-in hybrids and 76,000 electric vans cut oil-related emissions by at least 5.9MtCO2e, Carbon Brief analysis finds, only slightly offset by around 0.5MtCO2e from higher electricity demand.
- The UK’s EV motorists each saved around £800, on average, in 2024 – some £1.7bn in total – relative to the cost of driving petrol or diesel vehicles.
- Gas demand for heating increased, despite warmer average temperatures than in 2023, as prices eased from the peaks seen after the global energy crisis.
- However, gas demand fell overall due to lower gas-fired electricity generation, thanks to higher electricity imports and increased output from low-carbon sources.
The UK would need to cut its emissions by a larger amount each year than it did in 2024, to reach its international climate goal for 2035, as well as its national target to reach net-zero by 2050.
The analysis is the latest in a decade-long series of annual estimates from Carbon Brief, covering emissions during 2023, 2022, 2020, 2019, 2018, 2017, 2016, 2015 and 2014.
Lowest since 1872
The UK’s territorial greenhouse gas emissions – those that occur within the country’s borders – have now fallen in 26 of the 35 years since 1990.
(Consumption-based emissions, including CO2 embedded in imported goods and services, were increasing until 2007, but have since fallen at a similar rate to territorial emissions.)
Apart from brief rebounds after the global financial crisis and the Covid-19 lockdowns, UK emissions have fallen every year for the past two decades.
The latest 14MtCO2e (3.6%) reduction takes UK emissions down to 371MtCO2e, according to Carbon Brief’s new analysis.
This is the lowest since 1872 and on par with 1926, when there was a general strike, as shown in the figure below. In 1872, Queen Victoria was on the throne and Wanderers beat Royal Engineers in the first-ever FA Cup final, held at Kennington Oval in south London.
The UK’s emissions are now definitively below the level reached only temporarily during the height of Covid in 2020, having fallen steadily in each of the past three years.
They are now at levels not seen consistently since Victorian times.
Coal collapse
The largest factor in emissions falling last year, accounting for around 7MtCO2e or two-thirds of the reduction overall, was a massive 54% drop in UK coal demand.
In percentage terms, this was the fastest annual reduction in UK coal demand on record, in figures going back to the 16th century. (In absolute terms, the 2.4Mt fall in coal use in 2024 is easily eclipsed by the 34Mt reduction seen during the 1984 miners’ strike.)
The UK used just 2.1Mt of coal in 2024. As shown in the figure below, this is the lowest amount since 1666, when the UK’s capital city was engulfed in the Great Fire of London.
Roughly one-third of the drop in coal use overall last year was due to the closure of the UK’s last coal-fired power station, at Ratcliffe-on-Soar in Nottinghamshire. (For more on how the UK became the first G7 country to phase out coal power, see Carbon Brief’s in-depth interactive feature.)
The plant supplied power to the grid for the last time in September 2024, bringing to an end a 142-year era of using coal to generate electricity in the UK.
The shift away from coal power towards low-carbon sources has been one of the driving forces of UK emissions cuts in recent years.
Indeed, in the period since the UK’s Climate Change Act was passed, the amount of coal used to generate electricity has dropped by 99%, from 48Mt in 2008 to less than 1Mt in 2024. This accounts for the large majority (84%) of the total reduction in coal use over the same period.
Steel slide
In 2024, however, two-thirds of the drop in UK coal consumption – and one-third of the drop in emissions overall – came from lower coal use by heavy industry.
This was largely due to lower steel production, which fell from 5.6Mt in 2023 to 4.0Mt in 2024, a reduction of 29%. This 1.6Mt drop in production was mostly offset by a 1.3Mt increase in imports.
The Port Talbot steelworks in Wales shut down its last two blast furnaces in April and September, with owner Tata blaming losses of £1m a day for the closures.
Since the site last made a profit in 2022, UK and global steel prices have fallen sharply, as shown in the figure below. US credit rating agency Fitch Ratings says the decline in prices, down to weak demand and high exports from China, is “putting pressure on producers’ margins”.
Many commentators have tried to blame climate policy or electricity prices for the steel sector’s problems. However, energy only makes up a tiny fraction of coal-based steel production costs.
Moreover, steelmakers around the world – from China to South Africa – are facing similar challenges, with prices falling as a result of supply being significantly greater than demand.
Industry group Eurofer says the European market is being “flooded by cheap foreign steel”. It adds that economic headwinds in China, including its real-estate slowdown, have seen “around 100m tonnes of Chinese steel…flooding major markets at dumping prices”.
As such, it is not at all clear that the UK steel sector would have fared differently – or that the Port Talbot blast furnaces would have remained open – in the absence of climate policy.
For example, the sector is part of the UK emissions trading scheme (UKETS), meaning it nominally faces a carbon price that imports from outside the EU would not have to pay.
Yet UK (and EU) steelmakers continue to receive free allowances to shield them from the risk of “leakage” due to competition from abroad. The Port Talbot steelworks received more than 21m free allowances to cover its emissions in the period 2021-2025, worth roughly £1bn. Similarly, the Scunthorpe steelworks received nearly 17m allowances worth around £0.8bn.
From 2027, the UK plans to follow the EU in shifting from free allowances to a carbon border adjustment mechanism (CBAM), under which importers must pay an equivalent carbon price.
The closure of the UK’s blast furnaces is not the end of the story for steelmaking in the country. Indeed, Tata has pledged an investment worth £1.25bn to reopen its Welsh site with electric arc furnaces, which do not rely on coal. This includes up to £0.5bn from the government. Tata says it will have the capacity to produce 3Mt of steel per year from late 2027 or early 2028.
Production also paused in 2024 at the Scunthorpe steelworks, run by the Chinese-owned British Steel, reportedly due to managers ordering the wrong type of coal. Its blast furnaces are now operating again, but it is also looking to shift to electric arc furnaces with government support.
The UK steel industry has welcomed the shift to electric arc furnaces, but has called for efforts to reduce electricity prices, including the 2024 “supercharger” scheme that exempts heavy industry from additional costs relating to renewable subsidies and electricity network charges.
The government’s February 2025 steel strategy looks at issues including “overcapacity in global markets” and the “influence of electricity prices on the competitiveness of the steel sector”.
Rise of EVs
After coal, the next-largest chunk of emissions cuts in 2024 came from lower demand for oil and gas, which accounted for around a third of the reduction overall.
The 1.4% drop in oil demand is particularly interesting, given that traffic on the UK’s roads has been increasing in recent years.
The number of miles driven on UK roads increased by more than 1% in 2024 and is now close to pre-pandemic levels. Yet UK demand for road-transport fuels fell by another 1.6% in 2024 and is now nearly 14% lower than it was in 2019, as shown in the figure below.
Along with improvements in fuel efficiency, the rise of EVs is a key part of this phenomenon.
The UK’s right-leaning newspapers have been busy finding new driving-related wordplay for what they have misleadingly described as a “stalling” market for EVs, which is apparently “going into reverse”.
The reality is that the number of EVs on the UK’s road rose from 1m in 2023 to 1.4m in 2024, an increase of 39% in just one year. The number of plug-in hybrids was up 28% to 0.8m.
Along with 76,000 electric vans, these EVs cut oil-related emissions by at least 5.9MtCO2e in 2024, Carbon Brief analysis finds, relative to similar vehicles burning petrol or diesel fuel.
These electrified vehicles have added around 4 terawatt hours to UK electricity demand in 2024, around 1% of the total. As such, the emissions associated with additional electricity generation, at around 0.5MtCO2e, offsets less than 10% of the savings from reduced oil use.
(On a lifecycle basis, EVs in the UK cut emissions by around 70% taking into account the emissions associated with manufacturing the cars, their batteries and fuelling them during use.)
Even more strikingly, the UK’s EV drivers saved around £1.7bn in lower fuel costs in 2024, Carbon Brief analysis finds, relative to petrol or diesel vehicles.
These savings, averaging roughly £800 per vehicle per year, conservatively assume that charging takes place at domestic retail electricity prices, rather than reduced-rate overnight tariffs.
Greenhouse gas emissions from burning gas also dipped in 2024, as demand for the fuel reached a record low. The roughly 2MtCO2e drop in emissions from gas made up around a sixth of the reduction in the UK overall and reflects the combined impact of competing trends.
Demand for heating in buildings (+3.8%) and offices (+0.6%) increased, despite temperatures being above average and higher than a year earlier. Industrial gas use also increased (+0.3%).
This is likely the result of lower fuel prices, which have eased since the peaks seen during the early phase of the global energy crisis precipitated by Russia’s invasion of Ukraine in 2022.
In contrast, gas demand for generating power fell by 13%, helping to make the UK’s electricity in 2024 the “cleanest ever”. This reduction was due to an increase in output from low-carbon sources, as well as an increase in the amount of cheap electricity imported from overseas.
A small, but still notable contributor to lower UK gas demand in 2024 came from reduced imports of liquified natural gas (LNG), which roughly halved compared with a year earlier.
Following Russia’s invasion, the UK had acted as an import hub for the rest of Europe, taking deliveries of LNG and then re-exporting the gas to the continent via pipelines. In 2024, however, European demand for gas eased and UK exports via the pipeline to Belgium also halved.
Import terminals use some of the gas they handle to “regasify” the supercooled LNG cargo that arrives by ship, turning it back into a gas that can be fed into pipelines. (The emissions associated with this process count towards the UK’s territorial total, even if the gas is burned overseas.)
In 2023, these terminals had used some 3TWh of gas, equivalent to the heating needs of half the homes in Birmingham. In 2024, LNG terminals used half this amount.
Emissions decoupling
While the UK’s emissions have fallen in most years since 1990, the baseline for the nation’s climate goals, the size of its economy has nearly doubled.
Specifically, emissions are “decoupling” from economic growth, having fallen to 54% below 1990 levels while GDP is up 84%, as shown in the figure below.
Taking an even longer view, the UK’s £2tn economy is now about 20 times larger than it was in 1872, after adjusting for inflation, whereas emissions are roughly the same.
Moreover, considering its population is now nearly 70 million people compared to 32m in 1872, the UK’s per-capita emissions have fallen two-fold, from 11.3tCO2e in 1872 to 5.4CO2e in 2024.
The 14MtCO2e drop in emissions in 2024 can be compared with the trajectory needed to reach the UK’s national and international climate pledges for 2035 and 2050.
If emissions fell by the same amount every year as they did in 2024, then the UK would miss both targets. It would need to cut emissions by 20MtCO2e each year to meet the 2035 target and by an average of 15MtCO2e per year to reach net-zero emissions by 2050.
In other words, annual emissions cuts would need to accelerate in the short- to medium-term, but could start to ease off later on. This is consistent with the cost-effective pathway to net-zero set out last month by the Climate Change Committee in its latest advice to the government.
Methodology
The starting point for Carbon Brief’s analysis of UK greenhouse gas emissions is preliminary government estimates of energy use by fuel. These are published quarterly, with the final quarter of each year appearing in figures published at the end of the following February. The same approach has accurately estimated year-to-year changes in emissions in previous years (see table, below).

|---|---|---|---|
| 2010 | 2.4 | 2.6 | 0.2 |
| 2011 | -7.3 | -7.7 | -0.4 |
| 2012 | 2.9 | 3.6 | 0.7 |

Annual change in UK greenhouse gas emissions, %
One large source of uncertainty is the provisional energy use data, which is revised at the end of March each year and often again later on. Emissions data is also subject to revision in light of improvements in data collection and the methodology used, with major revisions in 2021.
The table above applies Carbon Brief’s emissions calculations to the comparable energy use and emissions figures, which may differ from those published previously.
Another source of uncertainty is the fact that Carbon Brief’s approach to estimating the annual change in emissions differs from the methodology used for the government’s own provisional estimates. The government has access to more granular data not available for public use.
Carbon Brief’s analysis takes figures on the amount of energy sourced from coal, oil and gas reported in Energy Trends 1.2. These figures are combined with conversion factors for the CO2 emissions per unit of energy, published annually by the UK government. Conversion factors are available for each fuel type, for example, petrol, diesel, gas and coal for electricity generation.
For oil, the analysis also draws on Energy Trends 3.13, which further breaks down demand according to the subtype of oil, for example, petrol, jet fuel and so on. Similarly, for coal, the analysis draws on Energy Trends 2.6, which breaks down solid fuel use by subtype.
Emissions from each fuel are then estimated from the energy use multiplied by the conversion factor, weighted by the relative proportions for each fuel subtype.
For example, the UK uses roughly 50m tonnes of oil equivalent (Mtoe) in the form of oil products, around half of which is from road diesel. So half the total energy use from oil is combined with the conversion factor for road diesel, another one-fifth for petrol and so on.
Energy use from each fossil fuel subtype is mapped onto the appropriate emissions conversion factor. In some cases, there is no direct read-across, in which case the nearest appropriate substitute is used. For example, energy use listed as “bitumen” is mapped to “processed fuel oils – residual oil”. Similarly, solid fuel used by “other conversion industries” is mapped to “petroleum coke”, and “other” solid fuel use is mapped to “coal (domestic)”.
The energy use figures are calculated on an inland consumption basis, meaning they include bunkers consumed in the UK for international transport by air and sea. In contrast, national emissions inventories exclude international aviation and shipping.
The analysis, therefore, estimates and removes the part of oil use that is due to the UK’s share of international aviation. It draws on the UK’s final greenhouse gas emissions inventory, which breaks emissions down by sector and reports the total for domestic aviation.
This domestic emissions figure is compared with the estimated emissions due to jet fuel use overall, based on the appropriate conversion factor. The analysis assumes that domestic aviation’s share of emissions is equivalent to its share of jet fuel energy use.
In addition to estimating CO2 emissions from fossil fuel use, Carbon Brief assumes that CO2 emissions from non-fuel sources, such as land-use change and forestry, are the same as a year earlier. The remaining greenhouse gas emissions are assumed to change in line with the latest government energy and emissions projections.
These assumptions are based on the UK government’s own methodology for preliminary greenhouse gas emissions estimates, published in 2019.
Note that the figures in this article are for emissions within the UK measured according to international guidelines. This means they exclude emissions associated with imported goods, including imported biomass, as well as the UK’s share of international aviation and shipping.
The Office for National Statistics (ONS) has published detailed comparisons between various different approaches to calculating UK emissions, on a territorial, consumption, environmental accounts or international accounting basis.
The UK’s consumption-based CO2 emissions increased between 1990 and 2007. Since then, however, they have fallen by a similar number of tonnes as emissions within the UK.
Bioenergy is a significant source of renewable energy in the UK and its climate benefits are disputed. Contrary to public perception, however, only around one-quarter of bioenergy is imported.
International aviation is considered part of the UK’s carbon budgets and faces the prospect of tighter limits on its CO2 emissions. The international shipping sector has a target to at least halve its emissions by 2050, relative to 2008 levels.

The global roadmap on transitioning away from fossil fuels now being developed should be a “continuing conversation” which is part of UN climate talks, not just a one-off report, several governments told the Brazilian COP30 Presidency on Friday in Bonn.
During a 90-minute exchange of views at the annual mid-year climate talks in Germany, several European governments and the Marshall Islands said the roadmap that Brazil is due to finish by November should be incorporated into the official negotiations.
Any such push is likely to be resisted by nations whose economies are reliant on fossil fuel production. While Russia did not speak on Friday, it has said in earlier written submissions that the roadmap should not be referenced in any document approved by governments at UN climate talks.
At COP30 last year, Brazil tried to get governments to agree to produce a roadmap on how to transition away from fossil fuels but the proposal did not win consensus, with major nations like Saudi Arabia and Russia opposed.
Feedback in Bonn
To save the day, Brazil’s COP30 president André Aranha Corrêa do Lago promised at the closing plenary in Belem to draw up a voluntary roadmap in consultation with interested governments. Over 20 countries have officially submitted their opinions on this roadmap and, in Bonn on Friday, Corrêa do Lago sought their views – and those of civil society – in person after the presidency presented its findings so far.
The roadmap will also incorporate outcomes from the first global conference on transitioning away from fossil fuels held in Santa Marta, Colombia, in April and attended by around 60 countries.
A negotiator for the Marshall Islands told Friday’s meeting that at COP31 this year all governments should “welcome the collaborative effort behind the roadmap and the Santa Marta conference and for this work to be taken on to COP32 and beyond”.

COP31 leaders unveil global targets, with spotlight on electrification
Co-hosts Türkiye and Australia want countries to sign on to global targets in three of their priority areas for this year’s COP climate negotiations
A spokesperson for Switzerland said on behalf of a group of nations which includes South Korea and Mexico that the roadmap must be a “sustained process, not a one-off report” and “we would welcome an ongoing platform for dialogue, for learning and cooperation including among fossil-fuel production countries”.
“We expect more than a document, rather a process whereby we come together to develop concrete steps, recommendations and tools to prepare for the transitions,” she said, calling on the COP31 co-presidents Australia and Turkiye and COP32 host Ethiopia to “take up the leadership” for implementing the roadmap”.
Global stocktake response
France’s negotiator said the roadmap “is a process and we will need continuing discussions” as “implementation needs time”, while the UK called for a “continuing conversation, including as we head towards the second [global stocktake]”.
The global stocktake (GST) is an official five-yearly report into how the world’s governments are doing on their Paris Agreement goal to limit global warming to 1.5C above pre-industrial temperatures.
The second stocktake will be published in 2028 and governments are likely to negotiate a response to it, which could include new commitments to reduce emissions, at COP33 that year. The response to the first global stocktake included the landmark COP28 commitment to transitioning away from fossil fuels in energy systems.
“Even though it’s not a formal part of the negotiation agenda, the roadmap can be a key input for the entire information-gathering phase of the second GST,” Enrique Maurtua Konstantinidis, an independent climate policy consultant, explained to Climate Home News.
“The key is for countries not to focus the discussion on defending the roadmap itself, but rather on its content, which is what truly matters,” he added.
At the Bonn event, civil society organisations also supported continuing the roadmap inside the formal climate process.
Natalie Jones, policy adviser for the International Institute for Sustainable Development, told Climate Home News the roadmap should be “an ongoing dialogue where countries can exchange their experiences, best practices and continue implementing the [transitioning away from fossil fuels] consensus”.
Russian resistance
But economies reliant on fossil fuel production are likely to oppose incorporating the roadmap into negotiations in Bonn and at COP summits. Russia’s written submission to Brazil’s consultation says the roadmap was not agreed by governments at COP30.
It says such work should therefore take place on the margins of the UNFCCC process, adding that “ the inclusion of any references to the “Roadmap” in the agenda or in official or informal documents” at Bonn or COP “would constitute a deviation from previously agreed consensus outcomes”.
Other major oil and gas producers like Saudi Arabia have not made written or spoken submissions and the US, as it has left the Paris Agreement, is not involved in discussions. But countries other than Russia are likely to resist incorporating the roadmap into official talks.
The submission by Japan, which is not a major producer of fossil fuels but consumes them from overseas, suggests nervousness about the roadmap. It asks Brazil for clarity on how the roadmap is “envisaged to be utilised” and argues that as many countries continue to rely on fossil fuels for electricity, a full and fast shift to “full decarbonisation” is “challenging.
After Friday’s event, Corrêa do Lago told Climate Home News that “the suggestions and the key milestones of the roadmap are not clear yet”. He added that the next step for the COP30 presidency will be to “sit down in July and August to really prepare” the content.
The veteran Brazilian diplomat added that the roadmap will have a section on the challenges of the transition and another section on solutions.
National fossil fuel roadmaps
Brazil, as COP30 president, is drawing up the global roadmap but its leader Lula da Silva has also ordered his officials to draw up a national roadmap.
In April, France became the first and so far only nation to produce a roadmap, which amalgamated different existing energy and decarbonisation plans and targets. Colombia is reportedly drawing up a roadmap too, based on a draft document by academics.
On Friday, a coalition of nearly 100 civil society organisations called on the COP31 co-presidents Australia and Türkiye to both come up with national roadmaps in order to “lead by example”. Türkiye produces about a third of its electricity from coal, while Australia is the world’s third-largest fossil fuel exporter, the NGOs said.
But in the Brazil-led consultation meeting, a Norwegian negotiator downplayed the importance of separate national roadmaps for transitioning away from fossil fuels.
While they can “have a supporting role”, the official said countries’ nationally determined contributions (NDCs) “must remain the primary vehicle for driving global climate transition.”
NDCs are climate plans, usually containing emissions reduction targets, which the Paris Agreement states governments must update with higher ambition every five years.

DeBriefed 12 June 2026: El Niño begins | COP31 hosts eye electrification | Atlantic current monitoring at risk
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
El Niño begins
‘DOMINO WEATHER’: The natural weather phenomenon El Niño, which can raise global heat and “bring domino weather effects across the planet”, is now underway, the US National Oceanic and Atmospheric Administration (NOAA) declared on Thursday, reported the Washington Post. The Japanese Meteorological Administration also identified the start of El Niño on Wednesday, said Bloomberg. According to the Japanese weather agency, the event is “expected to intensify in the coming months and become very strong later in the year, persisting into at least December”, reported the outlet.
‘SUPER EVENT’: BBC News reported that “many forecasts suggest this could end up as a so-called ‘super’ El Niño” and be “among the strongest ever recorded”. It added: “Coming on top of decades of human-caused warming, it could bring another record-hot year – most likely in 2027 – with disruption to weather, food supplies and economies running well into that year.”
COP31 hosts eye electrification
‘35 BY 35’: COP31 hosts Turkey and Australia have called for countries to support a target of electrifying 35% of global energy use by 2035, reported Politico. Speaking at climate talks in Bonn, Germany, Turkish minister Murat Kurum said that electrification would be a “flagship priority” at the COP31 summit, noted the publication. Kurum added that “electrifying daily life, from transport to buildings and industry” could “protect families and businesses from volatile energy markets”, said the outlet.
WASTE AND BUILDINGS: Climate Home News reported that electrification was one of three priorities unveiled by the COP31 hosts, with the other two being waste and buildings. On buildings, the COP31 hosts “quietly overhauled [their] goal”, Climate Home News said. It reported: “An initial press statement on Monday set out a target ‘to achieve at least a 25% increase in energy efficiency in buildings by 2035’. But…on Tuesday, that was replaced with a different goal to ‘reduce energy consumption intensity in the building sector by at least 25% by 2035’.”
‘HARDEST’ CHALLENGE: Elsewhere in Bonn, UN climate chief Simon Stiell said “governments must stop revisiting climate commitments and start delivering on them”, South Africa’s Mail and Guardian reported. It quoted Stiell as saying: “Tackling the global climate crisis is the hardest but most important thing humanity has ever tried to do together…We are not yet where we need to be. But we are somewhere we have never been before.”
Around the world
- ETS EXTRA: The EU has agreed “stronger” price controls on “ETS2”, its planned trading system for heating and transport emissions, according to Reuters.
- OCEAN STRESS: The rate of sea level rise has doubled in 10 years amid “severe and accelerating” pressures on oceans, said a UN report covered by Time.
- CLIMATE MIGRANTS: Donald Trump’s “immigration crackdown is largely targeting people from the countries most vulnerable to displacement from climate-driven disasters”, according to Guardian analysis.
- ULTRA-RICH: Investments by the world’s ultra-rich in 2022 are linked to nearly $1tn in climate damages, according to a Greenpeace Africa analysis covered by BusinessGreen.

Captured
Solar power has overtaken gas in Asia to become the region’s third largest electricity source behind coal and hydropower, according to Carbon Brief analysis of data from the thinktank Ember. Solar became the third largest electricity source for Asia on an annual basis in April 2026, according to the analysis. In the year to April 2026, solar generated 1,727 terawatt hours (TWh), while gas generated 1,711TWh, it added.
Spotlight
Atlantic current monitoring at risk
This week, Carbon Brief reports on how Trump plans could disrupt efforts to track a major ocean current.
The Irminger Sea, a patch of frigid ocean east of Greenland, plays an outsized role in the Earth’s climate.
Here, surface water that has travelled thousands of kilometres from the tropics grows cold and dense enough to sink to the ocean’s depths – a transformation that must occur for the water to begin a long journey back to the southern hemisphere.
This makes the Irminger Sea an “action centre” for the mighty Atlantic Meridional Overturning Circulation (AMOC), the vast system of ocean currents that keeps temperatures in Europe mild.
Last week, the US government announced plans to dismantle ocean moorings installed in the Irminger Sea which, among other things, collect data on the health of the AMOC.
This came as part of a programme to “descope” the Ocean Observatories Initiative, a $368m network of ocean sensors installed in the Pacific and Atlantic oceans.
Two of the moorings earmarked for removal in the Irminger Sea form part of an internationally funded, trans-Atlantic AMOC monitoring array, known as OSNAP, that stretches from Canada to Scotland.
Experts told Carbon Brief the move by the Trump administration highlights the vulnerability of AMOC observation systems around the world. These deep-sea moorings – scattered across the Atlantic – collect real-time data on, among other things, ocean current, temperature, pressure and biochemistry.
Prof Penny Holliday, chief scientific officer of the UK National Oceanography Centre, told Carbon Brief that the OSNAP array, as well as the RAPID array at 26N, are “entirely dependent” on research grants that have to be “continually reapplied for”.
“Funding is perilous all the time,” she said.
A report prepared last month by scientists for Nordic ministers exploring the security of funding for AMOC observing systems warned that RAPID and OSNAP were in “critical condition” and faced “material exposure over an 18-month horizon”. Meanwhile, other key basin-wide and global components of the global AMOC observing system were rated as “at risk”.
It is not just US funding that is uncertain. The report notes, for example, that the five-yearly funding the UK provides to RAPID and OSNAP is “at risk from 2027 due to year-on-year budget reductions” at the Natural Environmental Research Council.
(RAPID is funded by the US and UK, whereas OSNAP is backed by five different countries, with the US contributing half of the total financial support.)
Report co-author Dr Femke de Jong from the Royal Netherlands Institute for Sea Research told Carbon Brief that “continued AMOC observations” are under pressure in “multiple countries”. She said:
“While the risk of a declining AMOC to society is starting to be recognised, there is not yet a system or institution in place to guarantee a way to monitor it.”
AMOC monitoring arrays are still in their infancy – RAPID, the oldest, was launched in 2004. Two decades of data captured so far shows that the AMOC is slowing down. However, scientists will need many more years of data to be able to confidently link the decline to climate change, rather than natural variability in the ocean.
NOC’s Holliday points to the disconnect between scientific and funder timelines:
“The timescale of observations needed in order to be able to detect a climate change signal from the very naturally variable ocean is around 40-60 years…. [And yet], in the Netherlands, they have to apply for a new grant for their ocean moorings every two years. They are going to have to do that for 40 years.
“This is a very inefficient way of getting funding for what should be critical infrastructure.”
