As another year of record emissions draws to an end, it’s worth looking back on what’s been achieved.
Like every year, the quick answer is more than nothing but less than enough. To dissect that in more detail, here are our six takeaways from the year in climate.
1. Oil and gas felt the heat
Phasing out or down fossil fuels? Abated or unabated? Scaling up renewables, carbon capture and storage (CCS) and techno solutions. Energy dilemmas, and their buzzwords animated international talks in 2023.
The headline breakthrough came at the end. The Cop28 agreement included for the first time a goal to move away from all fossil fuels in energy systems.
It was the centrepiece of a bigger package that included a call for the tripling of renewables and doubling energy efficiency by 2030.
But it also gave a platform to “transitional fuels” (read gas) and CCS, which some politicians and campaigners regard as “dangerous loopholes” for continued fossil fuel use.
Cop hosts the UAE and most developed countries welcomed the deal as “historic”. For small island states and other vulnerable nations it did not go far enough.
Like most Cop agreements, it was the result of a hard-won compromise struck in overtime – after Saudi-led opposition threatened to leave oil and gas out of the text altogether.

The road to Dubai had been equally bumpy. The G7 saw fights over gas and coal with hosts Japan attempting to push controversial strategies like ammonia co-firing.
The G20 in Delhi offered a dress rehearsal of what was to expect at Cop with broad agreement over renewables and bitter disputes over fossil fuels.
In the background, Sultan Al Jaber, oil executive turned Cop president, garnered constant curiosity and scrutiny. He was initially adamant that the focus should be on emissions and not on the fuels themselves, raising more than an eyebrow. But, amid a series of controversies and apparent slip-ups, his position gradually shifted.
Al Jaber contended the Dubai deal would be enough to keep the 1.5C goal in sight. A day later he told the Guardian that Adnoc, the oil firm he runs, would press ahead with a massive oil and gas expansion.
Other rich nations, like the US, keep him company on that front. Such chasms between words and actions will continue to be closely watched.
2. Slow progress on climate cash
The other side of the coin from the fossil fuels debate is finance. When rich countries ask their developing counterparts to sign on to ambitious energy transition plans, many reply: ‘who is going to be paying for that?’
When governments wrangled over targets for adapting to climate change, similar questions were asked.
A clear answer was never forthcoming. We might get more clarity in 2024, with governments set to discuss, and hopefully agree on, a new collective goal at Cop29 in Baku in November.
But a lack of trust has taken root. Rich countries have so far not respected the previous commitment to provide $100 billion a year in climate finance to vulnerable countries.
That was “likely” met in 2022, two years after the original deadline, according to the OECD. We will be looking out for the receipts for confirmation.
Countries were also invited to refill the coffers of the Green Climate Fund. The four-yearly replenishment round got off to a decent start, but an underwhelming pledging summit in October put ambition at risk.
Then the US landed in Dubai in December with a $3 billion funding promise. It brought total pledges to $12.8 billion – setting the GCF on course for a “middling” level of ambition.
But that comes with a gigantic caveat. To deliver the dollars, the Biden administration will have to persuade Republicans in Congress or take control of it by winning elections. Both are tall orders.

Money talked outside UN diplomacy too. Lots of attention centred on the much-touted reforms of multilateral development banks inspired by the Bridgetown Agenda.
Progress has been slower than many were hoping for. The World Bank lowered its equity-to-loan ratio, freeing up $4 billion a year.
It also installed a new more climate-aware president, officially changed its mission statement and promised pauses in debt repayments for disaster-hit countries. Encouraging steps, but far short of the trillions of dollars developing countries have been calling for.
3.US-China climate talks thawed
Formal diplomatic relations between the world’s biggest polluters suffered an ice-age-like deep freeze in the latter part of 2022 after US Congressional leader Nancy Pelosi visited Taiwan. Climate talks were collateral damage.
But 2023 saw a slow but steady thawing. It culminated in a momentous bilateral meeting held in Califonia’s Sunnylands resort a few weeks before Cop28.
The countries’ respective climate envoys, John Kerry and Xie Zhenhua, agreed to revive a climate working group and sketched out the outline of a potential alignment in the upcoming negotiations.
It proved decisive. In particular, their joint support to “accelerate the substitution for coal, oil and gas generation” helped find the right formula to unstick the thorny energy language in Dubai.

The special personal relationship between Kerry and Xie was a big factor in these improved relations.
When formal diplomacy was on hold, the two kept talking. Xie even brought his grandson to Dubai because the 8-year-old wanted to say “happy birthday to my good friend Mr. Kerry”, who turned 80 during the summit.
But Cop28 was most likely their last hurrah together. Xie is set to retire soon ending a 16-years on-and-off stint. He is likely to be replaced by Liu Zhenmin, a former vice foreign minister.
Kerry has been vague about his future with US elections looming large on the horizon. He recently told Reuters that he would “continue as long as God gives me the breath and work on it [climate] one way or the other”.
4. Carbon credits terrible year
To say 2023 won’t be remembered as carbon credits’ finest year is an understatement. It began with a now-infamous report pouring cold water on forestry-based offsets and ended with talks over Article 6 falling apart spectacularly in Dubai.
In between, scandal after scandal dented the reputation of carbon markets. From the collapse of the world’s second largest project to the suspension of dozens of schemes over exaggerated claims or alleged human rights violations. The blowback prompted even some of the most enthusiastic corporate credits buyers to cool on the idea.

Many carbon market supporters had pinned hopes on Cop28 for a spot of good news. Ahead of the talks, it looked like governments could finally fire the starting gun on the creation of a long-awaited global carbon market under the Paris Agreement.
But those hopes were misplaced. Negotiations ended without an outcome following a bitter disagreement over integrity rules between the US and the EU.
Leaping on the string of failures, some critics have been pushing for the whole concept of carbon offsetting to be chucked into the dustbin of history.
But others claim carbon markets provide an essential source of finance for developing nations, love it or loathe it. They are trying to build them back up from the nadir with more stringent climate provisions and better social safeguards.
5. Coal-to-clean deals reality check
As promises turned into proper plans, Just energy transition partnerships (Jetp) hit the cold wall of reality in 2023. The three initial deals – with South Africa, Indonesia and Vietnam – have all been beset by issues.
The type of money put on the table by rich nations has been a source of common grievance. Grants make up a very small percentage of the funding packages, fuelling fears over debt. As a result, recipient countries revised climate targets downwards.

Indonesia has watered down coal retirement plans. It now aims to start shutting down on-grid plants before their scheduled closure no earlier than 2035 – five years later than originally planned.
So-called captive plants, that power specific industries, have also caused a massive headache. Wrong assumptions meant a much lower number of them were baked in the original modelling. Struggling to find a way out, the Indonesian government has so far excluded them – and their emissions – wholesale from the Jetp blueprint.
Vietnam’s investment plan, unveiled during Cop28, has no timeline at all for retiring coal. It expects instead to operate plants “flexibly” and to rely on the controversial co-firing of biomass and ammonia with coal.
The authoritarian Vietnamese government has also all but buried the ‘just’ aspect of the partnership. It has jailed five environmentalists on tax evasion charges, which human rights groups say are trumped-up accusations.

In South Africa, the transition is meant to be reasonably easier as its Apartheid-era coal plants are nearing retirement. But crippling blackouts prompted President Cyril Ramaphosa to say the timetable “must be relooked at” earlier this year.
The plan is also facing fierce opposition from the powerful coal lobby. Our investigation with Oxpeckers discovered the sector partnered with politicians and even managed to water down or delay key policies in a bid to sink the scheme.
6. Loss and damage fund’s good start
As the Cop27 president gavelled the landmark decision on a loss and damage fund in Sharm-el-Sheik, a question loomed large: will countries manage to agree on how it should work within the following 12 months?
‘Yes, definitely’ was the answer.
Governments adopted the decision on operationalising the fund on the very first day of Cop28. It gave the summit’s president Al Jaber an early win and prevented loss and damage from being used as a bargaining chip in the ensuing negotiations.
The success is down to the painstaking work of a 24-member transitional committee that hashed out the details over five gruelling meetings. At the outset, developed and developing countries were at odds on just about everything: who should benefit from the fund, who is expected to pay into it, where it’s meant to be hosted.
Distances gradually narrowed and a compromise deal was eventually struck a month before the climate summit. The World Bank will initially host the fund for four years, despite strong resistance to its involvement from developing nations.

All developing countries “particularly vulnerable” to the effects of climate change will be eligible to benefit from the mechanism. However, the definition of vulnerability – one of the thorniest issues – has not yet been defined.
The decision “urges” developed countries to provide financial resources to the fund, while other nations are only “encouraged” to do so “on a voluntary basis”. Rich nations have been strongly pushing to broaden the donor pool and will likely keep up their efforts.
Pledges from a slew of countries should inject over $700 million for the start-up of the fund. The UAE won plaudits by committing $100 million. The US was lambasted for offering a paltry $17.5m, despite being the world’s largest economy and biggest historical emitter.

Key developments
New five-year plans
GENERATION TARGET: China today released its 15th five-year plan for building a “new-type energy system”, according to finance news outlet Cailianshe. It said the plan covered topics including energy sources, power-market reform and China’s role in clean-energy supply chains and climate governance. The plan, published by the National Development and Reform Commission, stated that China will aim for clean energy to constitute 30% of power generation by 2030 – up from approximately 22% today. It also stated that wind and solar will become the “mainstay” of China’s power mix. The government will work to increase clean-energy consumption, such as by upgrading the grid to “accommodate” 900 gigawatts of distributed energy and promoting emerging solutions such as virtual power plants and hydrogen. The plan also urged the “strengthening” of coal’s role as a “bottom-line guarantee”.
IN THE WORKS: At a meeting on 11 June, China’s State Council approved the “15th five-year plan for building a beautiful China”, reported industry news outlet BJX News. The meeting readout noted the importance of “actively address[ing] climate change” and developing “green production and lifestyles”, it added. The next day, the Ministry of Ecology and Environment (MEE) approved a series of environment-related five-year plans, including the “15th five-year plan for a national response to climate change”, said business news outlet 21st Century Business Herald article. The full text of the plans is not yet available.
JOBS AND GOVERNANCE: A separate five-year plan on employment included calls to “unlock employment potential” by developing “new energy system” projects, according to current affairs outlet China News. The government also published a white paper on global governance that said the “general public truly feels that nations are taking action and that unity can overcome any obstacle” to address climate change, reported state news agency Xinhua. It added that the paper called on developed countries to “honor their commitments” on climate finance. Foreign minister Wang Yi said in a press conference that China aims to “innovate governance mechanisms” to address issues such as how countries can “achieve” a global low-carbon transition, Xinhua also reported.
Critical mineral barbs
REDUCE DEPENDENCIES: The Group of Seven (G7) major economies have stated that “no single country should supply more than 60% of their imports of rare earths”, reported Bloomberg, in “an effort to reduce their reliance on China”. The full communique, which does not mention China by name, said that diversifying supply chains was “urgen[t]”, due to “market concentration”, the “growing use of arbitrary trade restrictions” and the need to “reduce vulnerabilities”. In response, China’s foreign ministry urged the G7 to “stop disrupting the international trade order” with “self-made rules”.
EXPORTS BLOCKED: The Indonesian government’s new nickel production quotas and pricing rules could put $50bn of Chinese investment at risk, Chinese diplomats argued in a letter covered by the Financial Times. Lithium miners in Zimbabwe, including Chinese firms, are asking for more time to build local processing facilities ahead of a 2027 lithium concentrate export ban, said Reuters. Meanwhile, China restricted trade with two US rare-earth companies, in response to the US adding companies including CATL and BYD to a “blacklist”, said the Financial Times. China’s exports to Japan of rare earths used to make permanent magnets remain “negligible”, reported Reuters.
DIALOGUE URGED: EU member states have asked the European Commission to develop new trade instruments to deal with the “economic threat” posed by China, reported the Hong Kong-based South China Morning Post. Despite “combative rhetoric” ahead of the summit, the Financial Times reported that the 27 leaders opted for dialogue rather than immediate action to address “global macroeconomic imbalances”. Separately, the European Commission plans to impose tariffs on Chinese plug-in hybrid electric vehicles, reported German business newspaper Handelsblatt.
CLIMATE MINISTERIAL: The EU, China and Canada held a climate ministerial, in which Chinese environment minister Huang Runqiu said countries “must strengthen cooperation rather than retreat from it”, said Euronews. Climate outlet Tanpaifang reported that Huang also said COP31 should address “insufficient emission reduction efforts and financial support from developed countries”. According to a European Commission transcript, EU climate commissioner Wopke Hoekstra said: “We need to act for climate, but also for competitiveness and independence. We cannot afford to depend on third countries.”
Mandatory targets for energy users
NEW TARGETS: From August, the Chinese government will “set binding targets” for companies on how much low-carbon power and non-electric energy they must consume, said Bloomberg. It added that targets will be set for how much low-carbon power provinces must absorb into their grids. Provinces and “key energy-consuming industries” will see their uptake of clean energy monitored on a quarterly basis and be subject to annual assessments by the State Council, said industry news outlet International Energy Net.
END-USER PRESSURE: The announcement marks the first time that China has established targets for non-fossil energy consumption at the “end-user level”, reported economic news outlet Jiemian. It added that the previous system, which only covered power, placed the responsibility for absorbing renewable energy into the grid “primarily” onto local governments and power grid companies.
SUPPORTING THE MARKET: The new measures will “help address grid integration challenges and promote better utilisation of renewable energy”, an official at the National Energy Administration told reporters, according to Xinhua. The official said it would also help boost demand for other low-carbon industries, such as “green hydrogen, ammonia and methanol”. Liu Guobin, vice-president of the China Electric Power Planning and Engineering Institute said in an “explanation” posted on International Energy Net that the measures would also “convey clear…expectations to the market” for the long-term outlook for renewable energy, “guiding the rational allocation of investment”.
More China news
- BECALMED: China’s thermal power generation rose 2.1% year-on-year in May, as “lower wind speeds curbed renewable energy growth”, reported Reuters.
- TRUCK TARGET: The government issued a new plan for developing “new-energy heavy duty trucks (HDTs)” that aims to have sales of electric, hydrogen and other low-carbon HDTs account for 40% of new truck sales by 2030, said Xinhua.
- SUPERMASSIVE SYSTEM: China’s total power capacity reached 4,000 gigawatts in May, reported BJX News, larger than that of the US, EU, India, Russia and Japan combined. Coal’s share of the capacity mix fell to 32%, while the non-fossil share rose to 62%.
- EXPORT DRIVER: China’s exports of electric vehicles (EVs) rose 54% year-on-year in May to $10bn by value and lithium-battery exports “rose 37% to $8bn”, but solar cell exports fell 7% by value to $2bn, said Caixin. The thinktank Ember found that Chinese EV exports to south-east Asia, particularly Thailand and the Philippines, reached an “all-time high” of $1.2bn.
- ONGOING RISK: The heavy rainfall seen throughout June, as well as drought, is likely to continue during China’s flood season, said the Ministry of Emergency Management in comments covered by Jiemian.
- PROJECTION PUSHBACK: The China Energy Research Society’s Wang Weiquan described projections by BloombergNEF of China’s emissions reduction and share of coal in the power mix as “overly optimistic” and “even radical”, according to the state-run newspaper China Daily.
Spotlight
What is in China’s new three-year action plan for industry?
China has issued a new action plan for energy conservation and reducing carbon emissions across nine heavy industries.
In this issue, Carbon Brief examines how the plan will impact China’s industrial development and decarbonisation.
China will conduct an “intensive campaign for energy conservation and carbon reduction upgrades” across heavy industry between 2026 and 2028.
The plan targets nine key industries: steel; electrolytic aluminum; cement; flat glass; oil refining; ethylene; synthetic ammonia; methanol; and coal-fired power.
After 2028, it said that production capacity that does not meet efficiency standards will be phased out and that efforts will be broadened to other industries.
Combined, power and industry make up the vast majority of China’s emissions profile.
Emissions in some of these sectors – notably, steel and cement – have been falling. However, chemical-industry emissions have experienced double-digit growth.
China’s power sector, which generates the majority of its electricity through coal, is responsible for around 40% of the country’s total carbon dioxide (CO2) emissions.
Focused on efficiency
The plan outlined several measures for companies to take to reduce their energy use and emissions profile.
According to a Carbon Brief count, the majority are focused on energy efficiency, such as promoting high-efficiency industrial processes and upgrading energy-consuming equipment.
More than 70% of China’s steel, aluminium, cement and flat glass capacity does not meet energy efficiency benchmarks, said a government official in a Q&A published by the National Development and Reform Commission (NDRC).
Yang Zhou, senior advisor China at Agora Energiewende, told Carbon Brief that the policy will “pick the last lowest hanging fruit” in terms of eliminating low-efficiency capacity. After this, she said, the focus will turn to entering a “deep-water” phase of decarbonising industrial capacity, as well as making it more efficient.
Some of the measures that companies are encouraged to take in the plan do directly link to decarbonisation. These include developing “hydrogen metallurgy” and sourcing low-carbon materials and fuels, as well as increasing electrification and renewable power usage.
The coal-power industry should improve flexibility, decouple combined heat and power operations and integrate biomass and renewable energy into their operations, it said.
Coal plants are expected to reduce coal consumption per kilowatt-hour (kWh) of electricity by “at least five grams of standard coal” and carbon emissions per kWh by 10%-20%, if not more.
The document said that the share of coal-fired power capacity that meets energy efficiency benchmarks should improve by 15 percentage points by 2028. This rises to 20 percentage points for the other eight industries.
By 2028, according to the NDRC, the plan aims to cut energy use by more than 100m tonnes of standard coal per year and reduce CO2 emissions by more than 200m tonnes.
Supporting business
Companies will receive support from the central government, which will subsidise 20% of the total investment that “approved” projects require.
Provinces should “fully leverage” pricing mechanisms to encourage retrofitting, said the policy.
Local policymakers can now add a surcharge of up to 0.1 yuan ($0.15) per kWh to market-traded electricity prices for non-compliant producers – which finance outlet Caixin said was a “central” tool for enforcement.
The South China Morning Post quoted an unnamed analyst, however, saying the policy may not “deliver its intended effects”, as some industries still receive subsidised electricity from local governments.
Companies will also be able to use verified CO2 emission reductions from approved projects to “offset” emissions from “new, renovated or expanded” dual-high projects. For industries covered by China’s carbon market, this may be formalised in their emissions allowances.
The NDRC official said that support should be provided to “ensure they receive reasonable returns on their carbon emission allowances”.
The policy “seeks to strike a balance” between energy security and climate goals, rejecting the “radical thinking of ‘one-size-fits-all shutdowns and phase-outs’”, according to a widely-read commentary by Sprinting Power Worker, a “self-media” WeChat account.
“For industries such as coal power, steel and cement, a gradual capacity reduction is expected due to market forces,” said Yang. She added:
“For growing sectors like chemicals and non-ferrous metals, China’s strategy is to expand capacity, [albeit] increasingly concentrated, scaled-up and efficient. Continued decarbonisation will require large-scale deployment of solutions like electrification, green power-green hydrogen coupling and circular economy.”

4.9%
The amount by which China’s oil consumption is expected to fall in 2026 compared to the year before, according to a report by a thinktank under oil giant PetroChina, covered by Reuters. It said the decline is due to the “pivot to new energy and high oil prices due to the Iran war”, according to the report.

Twice as many animals died due to heat stress en route to slaughterhouses during the UK’s record-hot summer in 2025 compared to 2024, according to new Carbon Brief analysis.
Government figures showed that nearly 6,600 animals – mostly chickens – died in transport as a result of the sweltering summer heat in England and Wales from June to August 2025.
This compared to 3,100 in summer 2024 and no official cases in summer 2023.
These figures were still below the more than 18,500 deaths recorded in the summer of 2022 when UK temperatures hit 40C for the first time, as previously reported by Carbon Brief.
The deaths are a “horrifying reminder of what happens when animals are treated as cargo”, said an animal-rights group spokesperson.
Detailed descriptions included in the data on the deaths highlighted thousands of animals dying amid heat stress, high humidity levels and long journeys.
Thousands of animals also died due to cold, wintry conditions, with more than 13,000 deaths recorded between December 2024 and February 2025 – almost double the previous winter.
Heat deaths
Carbon Brief has analysed recent years of “dead on arrival” data focused on livestock that died due to heat or cold stress en route to slaughterhouses.
The data was obtained through the UK Freedom of Information (FOI) Act from the Food Standards Agency (FSA), which is responsible for the compliance of slaughterhouses in England and Wales.
At least 1m chickens die in the UK each year while being transported to slaughterhouses due to suffocation, poor transport procedures and other issues, reported the Bureau of Investigative Journalism in 2018 .
Pigs, cows, sheep and other animals also die in this way in smaller numbers.
The new data showed that 6,595 animals died due to heat stress en route to abattoirs between June and August 2025, which was the warmest summer on record in the UK.
According to the Met Office, human-caused climate change made this summer heat 70 times more likely to occur.
Carbon Brief requested non-publicly accessible details of “dead on arrival cases” that were categorised as “suspected heat/cold stress”.
Each incident contained a detailed description written by a vet with supporting evidence about the condition of the animals, the transport conditions and the suspected cause of death. These are filed to the FSA.
The information showed that certain individual days had particularly high death tolls. Almost 1,000 chickens died in a number of incidents during a heatwave on 11 July 2025. Some chickens showed visible signs of heat stress, such as panting and immobility, the reports said.
On 12 August, amid more high temperatures, 2,154 chickens died in heat-stress incidents.
Body temperatures of some of the chickens that died on this day were as high as 46C.
A chicken will die if its body temperature exceeds 45C and it should ideally stay as close to 41C as possible, according to a 2005 document from the Department for Environment, Food & Rural Affairs (Defra).
The table below shows the total number of heat- and cold-related deaths of livestock in recent years, based on the data obtained through FOI.
The “dead on arrival” information covered every summer and winter since 2023, alongside the summer of 2022.
The figures were likely an underestimate of the total number of livestock deaths due to high or low temperatures, as they only included deaths with “suspected cold/heat stress” as a listed category.
However, the incident descriptions in many other deaths mentioned high and low temperatures as contributing factors, despite the ultimate cause of death not being labelled as such. These were not included in Carbon Brief’s tally.
The figures covered deaths in England and Wales. Scotland and Northern Ireland do not record the cause of deaths en route to slaughterhouses, so it is not possible to single out the cases linked to high or low temperatures.
Preventing deaths
These livestock deaths are a “horrifying reminder of what happens when animals are treated as cargo”, says Alex Harman, campaigns manager at animal rights group Animal Aid. He tells Carbon Brief:
“These 6,600 individuals [in summer 2025] did not just die, they suffered prolonged, agonising heat exhaustion inside metal containers – anyone experiencing the UK’s heatwave this week will be able to empathise.”
Climate change is “simply amplifying the violence already built into animal farming”, he says, adding that the only “compassionate, logical” solution is to “stop viewing animals as products and urgently transition to a plant-based food system”.
Pigs and chickens cannot sweat and face difficulties cooling down on very hot days.
Cramped or long journeys can exacerbate this, combined with high humidity levels, sometimes upwards of 80%, the livestock data showed.
Abigail Penny, the executive director of Animal Equality UK, tells Carbon Brief that “these same scenes of extreme animal suffering play out every summer and, if nothing is done, it’s only going to get worse”.
Workers transporting animals during extreme weather conditions are expected to put in place measures to protect them, according to UK government guidance.
These measures can include ensuring water and ventilation systems function properly on vehicles, avoiding travel during the hottest or coldest parts of the day and recognising signs of heat and cold stress in animals.
The FSA said that the number of “dead on arrival” incidents caused by cold and heat stress increased by more than 50% between April 2024 and March 2025 compared to the same period the year prior.
The FSA and Defra declined Carbon Brief’s request to comment on the new figures.
Cold deaths
Thousands of animals also die due to cold stress while travelling to slaughterhouses each year. Carbon Brief assessed data for these deaths in the winters of 2023-24 and 2024-25.
At least 13,057 livestock animals died due to cold weather conditions between December 2024 and February 2025. This is more than double the number – 6,981 – that died the previous winter.
On 6 February 2025 alone, 4,056 poultry deaths were reported due to cold weather impacts.
Some livestock also died due to cold conditions in the summer months.
For example, 326 animals died amid cold weather in the summer of 2023. No official heat-related deaths were recorded in that period, but a number of incidents referred to hot-weather conditions or heat stress as contributing factors.
Overall, 2023 was a very warm year in the UK, with soaring temperatures in June and September. At least 3,103 animals died from heat stress in September, the figures also showed.
Conditions were cooler and wetter in July and August, which may have contributed to the absence of heat-stress deaths.
Most cold deaths during warmer months occurred in the early hours of the morning or overnight when temperatures dropped, the FOI data shows.
On 28 August 2025, for example, 134 chickens died due to cold stress. The incident description outlined that the animals were “very wet”, dirty and had few feathers, which can reduce a chicken’s ability to hold warmth.
The animals were transported overnight to a slaughterhouse and “suffered distress and pain” because of the weather and other factors, the description noted.

For the first time in the UK, more new electric vehicles (EVs) have been sold over a 12-month period than petrol cars, according to Carbon Brief analysis.
The news comes amid a battle over the future of the UK’s “zero-emissions vehicle” (ZEV) mandate, which the car industry and some unions are pushing to water down.
The mandate sets a rising target for the share of new car sales that must be “zero-emissions vehicles” (ZEVs) each year – primarily “pure” or “battery” EVs that only run on electricity.
The car industry argues that demand for these cars is too low to meet the requirements of the ZEV mandate, despite the fact that the industry has “over-complied” to date.
Carbon Brief’s analysis of the latest data on new UK car sales, shown in the figure below, illustrates that demand for EVs has, in fact, grown consistently – and it has now overtaken demand for petrol cars for the first time.
In the 12 months to May 2026, UK consumers bought 516,490 new BEVs, against only 504,010 new petrol cars.
Note that the analysis is based on figures from the European Automobile Manufacturers’ Association (ACEA). Figures published by the UK Society of Motor Manufacturers and Traders (SMMT) are based on a slightly different categorisation for hybrid cars.
All hybrids run entirely on petrol or diesel fuel, while also carrying a small battery and an electric motor. ACEA counts these cars separately to petrol and diesel models.
In contrast, the SMMT counts what it calls “mild” hybrids as petrol cars, while listing “full” hybrids – such as Toyota’s Prius – in a separate category.
The ACEA data shows that hybrids are the most popular type of car in the UK, as illustrated in the figure below, but also shows that their sales are relatively stagnant.
Some 56,321 hybrids were sold in May 2026, the most recent month with data from ACEA. This is an increase of 1,181 year-on-year, or just 2%.
In contrast, EV sales grew 34% to reach 43,931, while petrol cars were down 14% to 35,068.
Plug-in hybrids, which can be run on electricity from the grid or from a petrol engine, are also seeing relatively rapid sales growth, up 24% year-on-year in May 2026 to 22,167.
(In the UK, numberplates for “pure” EVs that only run on electricity are marked out by a distinctive green stripe on the left-hand side. These stripes are not used for any type of hybrid.)
The new analysis for the UK follows a similar milestone for the EU, with more BEVs having been sold in the month of December 2025 than petrol cars.
The UK first saw more sales of BEVs than petrol cars in a single month in December 2022, but this pattern has only been repeated on a consistent basis over the past year.
Globally, EV sales grew by 20% in 2025 and accounted for one in every four new cars sold, according to the International Energy Agency (IEA).
The agency said that global EV sales were set to grow by another 15% in 2026.
