The year 2024 was marked by violence and elections, as conflicts escalated around the world and billions of voters went to the polls.

However, climate change still made headlines.

Thousands of peer-reviewed journal articles were published over the course of the year, helping shape online discourse around climate change.

Tracking these mentions was Altmetric, an organisation that scores research papers according to the attention they receive online.

To do this, it tracks how often published peer-reviewed research is mentioned online in news articles, as well as on blogs, Wikipedia and on social media platforms such as Facebook, Reddit, Twitter and – in a new addition for 2024 – Bluesky. (Carbon Brief explained how Altmetric’s scoring system works in this article.)

Carbon Brief has parsed the data to compile its annual list of the 25 most talked-about climate-related papers of the past year.

The infographic above highlights the most mentioned climate papers of 2024, while the article analyses the top 25 research papers in greater detail, including the diversity and country affiliation of authors.

Overall, Altmetric’s data reveals the papers which generated the most online buzz in 2024 were – for the fourth year running – associated with Covid-19, with five of the 10 most talked-about papers of the year related to the virus.

However, a number of the most-shared studies were about climate change, from how warming is impacting ocean currents, the economy and timekeeping, through to efforts aimed at mapping historical temperatures using proxy data.

A return from last year’s highs

After a blockbuster year for online mentions of climate science in 2023, last year saw a return to more typical levels.

The most widely shared climate paper of 2024 has a score of 5,414, placing it at the bottom end of the range for top climate papers over the past seven years.

By contrast, the three most talked-about climate papers of 2023 received the highest attention scores recorded across all of Carbon Brief’s annual reviews, which date back to 2015. They clocked scores of 13,886, 8,686 and 7,821.

(For Carbon Brief’s previous Altmetric articles, see the links for 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2015.)

The graph below shows how the score given to the top paper in Carbon Brief’s annual review has changed over the past 10 years.

A spokesperson for Altmetric says the falling popularity of climate papers was not due to any adjustments to its methodology, noting that its scoring system “had not changed”. They tell Carbon Brief that online mentions of papers – across all disciplines – have declined in recent years from a peak in 2020, resulting in lower average scores across the board.

The spokesperson said it was unclear why the average number of mentions had fallen since 2020, but hypothesised that several factors could be at play. This includes a surge of policy citations during the Covid-19 pandemic and changes in how people use social media – such as a decline in posts on public Facebook feeds and a spike in Twitter posts in 2021.

The top 10 climate papers of 2024

  1. Physics-based early warning signal shows that AMOC is on tipping course
  2. The economic commitment of climate change
  3. 2023 summer warmth unparalleled over the past 2,000 years
  4. The growing inadequacy of an open-ended Saffir-Simpson hurricane wind scale in a warming world

  9. Accelerating glacier volume loss on Juneau Icefield driven by hypsometry and melt-accelerating feedbacks
  10. A 485-million-year history of Earth’s surface temperature

Later in this article, Carbon Brief looks at the rest of the top 25, and provides analysis of the most featured journals, as well as the gender diversity and country of origin of authors.

AMOC alarm

The most talked-about climate paper of 2024 is a Science Advances study that finds the Atlantic Meridional Overturning Circulation (AMOC) – a system of ocean currents that brings warm water up to Europe from the tropics and beyond – is “on route to tipping”.

The research, titled “Physics-based early warning signal shows that AMOC is on tipping course”, marks the first time that an AMOC tipping event has been identified in a cutting-edge climate model, in this case the Community Earth System Model.

The study’s Altmetric score of 5,414 shoots it to the top of Carbon Brief’s leaderboard and 1,272 points ahead of the second-placed paper.

However, as illustrated in the graph above, the research is the lowest-scoring climate paper to reach the top of the leaderboard since 2017.

Physics-based warning signal shows that AMOC is on tipping course

The researchers from the Institute for Marine and Atmospheric Research Utrecht describe the paper’s finding as “bad news for the climate system and humanity”. They explain:

“Up until now one could think that AMOC tipping was only a theoretical concept and tipping would disappear as soon as the full climate system, with all its additional feedbacks, was considered.”

The study paints a grisly picture of the consequences of a collapse of AMOC. This includes a 10-30C drop in winter temperatures in northern Europe within a century, and a “drastic change” in rainfall patterns in the Amazon. The paper states:

“These – and many more – impacts of an AMOC collapse have been known for a long time, but thus far have not been shown in a climate model of such high quality.”

Papers exploring the stability of AMOC have dominated Carbon Brief’s climate science leaderboard in recent years, coming in fourth and second place, respectively, in 2023 and 2021.

Media coverage has been amplified by disagreement over what metrics to use to measure the strength of AMOC. Previous studies have used sea surface temperature to make projections about when the tipping point may occur.

The Science Advances paper reaches its conclusions using a new, “physics-based” early warning signal for the breakdown of the vital ocean currents based on the salinity of water in the southern Atlantic.

Overall, the study racked up 601 news mentions, with the Times, Guardian, Daily Telegraph, Associated Press and CNN all reporting on its findings. It was also featured in 39 blogs, the highest of any paper in the top 25, and was shared more than 3,866 times on Twitter.

Study author Dr René van Westen tells Carbon Brief he believes the paper owes its popularity to its alarming conclusion that AMOC is approaching a tipping point, as well as the detail it offers around the “large-scale changes” and “substantial” climate impacts such an event could trigger. He explains:

“The urgency of the situation, suggesting that we are heading toward this collapse, underscores the need for immediate action to prevent such a scenario. We believe that the combination of these far-reaching climate impacts and the risk of AMOC collapse contributed to the extensive media coverage of our study.”

Economic commitment

The second highest-scoring climate paper of 2024, published in the journal Nature, is “The economic commitment of climate change”. The study has an Altmetric score of 4,142 and clocks in at second in the 2024 rankings.

The economic commitment of climate change

The three-person authorship team, from Germany’s Potsdam Institute for Climate Impact Research, used 40 years of data on damages from temperature and rainfall from more than 1,600 regions around the world to assess how damages could increase under a warming climate.

They estimate that the world economy is committed to an income reduction of 19% within the next 26 years, regardless of how rapidly humanity now cuts emissions. These damages are six times higher than the mitigation costs required to limit global warming to 2C in the near term, the authors say.

They also warn that climate change is likely to exacerbate existing inequalities, adding:

“The largest losses are committed at lower latitudes in regions with lower cumulative historical emissions and lower present-day income.”

The study was mentioned 55 times on Bluesky. It has also been cited by Wikipedia seven times, including in pages on climate justice and climate change mitigation.

The study’s lead author, Dr Maximilian Kotz, tells Carbon Brief:

“We think we made a helpful contribution by pushing the limits of the spatial scales, climate information and assumptions around long-term persistence which are used in these kinds of studies.”

However, he said the media coverage mainly focused on the final numbers, speculating that “part of the wide interest in the media was likely that these numbers were large”. He told Carbon Brief that, in his experience, it is “normal for the media not to pay much attention to the kind of details a researcher finds important”.

Kotz added that since his study came out, a number of other papers have been published using different approaches, but arriving at similar final numbers.

Record hot summer

Coming in third place is a Nature paper which uses temperatures reconstructed from tree rings to conclude the northern hemisphere summer of 2023 was the hottest in two millennia.

To build a picture of summer temperatures stretching back to AD1, the researchers turn to nine of the longest temperature-sensitive tree ring chronologies in North America and Europe, as well as observational data for 1901-2010.

2023 summer warmth unparalleled over the past 2,000 years

Rest of the top 10

In fourth place, with an Altmetric score of 3,907, is a paper that assesses whether the classification system for tropical cyclone wind speed needs to be expanded to reflect storms’ growing intensity in a warming world. It was published in Proceedings of the National Academy of Sciences.

The research, “The growing inadequacy of an open-ended Saffir-Simpson hurricane-wind scale in a warming world”, says climate change has led to more intense storms, which could justify a new category on the Saffir-Simpson scale.

Introduced in the 1970s, the scale is used to communicate the risk tropical cyclone winds present to property. Events are ranked from category 1, for storms with winds of 74-95 miles per hour (mph), to category 5 for storms with a wind-speed of 157mph and above.

The study highlights how five tropical cyclones of the last nine years were so intense they could sit in a hypothetical sixth category, which could cover storms with winds of 192mph and above.

The study received more news coverage than any other in this year’s top 25, amassing 720 mentions.

In fifth and sixth place, with scores of 3,757 and 3,248, respectively, are a pair of Nature papers.

The first, “Critical transitions in the Amazon forest system”, finds that by 2050, 10-47% of the Amazon forest will be exposed to “compounding disturbances” that may trigger a tipping point, causing a shift from lush rainforest to dry savannah. Carbon Brief covered the study.

The second is a paper looking at how rising ocean temperatures are endangering the Great Barrier Reef. It cautions that without “urgent intervention” the world’s largest coral reef system is at risk of experiencing “temperatures conducive to near-annual coral bleaching” with negative consequences for biodiversity and ecosystem services.

The seventh-placed paper finds a reduction in sulphur emissions from ships – driven by cleaner fuel regulations introduced in 2020 – has led to “substantial radiative warming” that could lead to a “doubling (or more)” of the rate of warming this decade. (Carbon Brief published its own analysis of how low-sulphur shipping rules are affecting global warming in 2023.)

The Communications Earth & Environment study goes on to suggest that marine cloud brightening – a geoengineering technique where marine low clouds are “seeded” with aerosols – may be a “viable” climate solution.

Coming in eighth is a paper which finds that ice melt in Greenland and Antarctica is delaying an observed acceleration of Earth’s rotation, with consequences for global timekeeping.

The Nature paper, “A global timekeeping problem postponed by global warming”, finds the redistribution of mass on Earth as polar ice melts means timekeepers will have to remove a second from global clocks around 2029. If it were not for the acceleration in polar ice melt, this second would have been due for removal by 2026, it says.

Timekeepers are no strangers to tweaking time to adjust for the Earth’s rotation; 27 leap seconds have been added to Coordinated Universal Time (UTC) since the 1970s. However, the paper cautions the first-ever removal of a second is set to pose “an unprecedented problem” for computer network timing.

(Similarly, in 25th place is a Proceedings of the National Academy of Science paper that finds melting ice sheets and glaciers are redistributing the planet’s mass, causing days to become longer by milliseconds.)

In ninth place is a Nature Communications paper which finds that rates of glacier area shrinkage on the Juneau ice field, which straddles Alaska and British Columbia, were five times faster over 2015-19 relative to 1948-79.

Rounding out the top 10 is a Science study that uses proxy data to conclude that the Earth’s average surface temperature has varied between 11C and 36C over the past 485m years.

Retracted papers go viral

One of the most shared papers of the year looks into a CO2 “saturation hypothesis” – a popular topic among climate sceptics. The theory contends the atmosphere has reached a CO2 saturation point, which means that additional emissions of the gas will cause little or no further warming.

The paper argues “continued and improved experimental work” is needed to ascertain whether “additionally emitted carbon dioxide into the atmosphere is indeed a greenhouse gas”.

The research, entitled “Climatic consequences of the process of saturation of radiation absorption in gases”, was published by Applications in Engineering Science in March, but subsequently retracted by the editor.

In a retraction notice, Applications in Engineering Science said the rigour and quality of the peer-review process for the paper had been “investigated and confirmed to fall beneath the high standards expected”.

While the paper received just four news mentions, it was widely shared on Twitter, clocking more than 6,000 posts. With a score of 2,661, it would have been the ninth most talked-about climate paper of 2024 had it not been retracted.

UK political commentator and climate sceptic Toby Young, who was recently promoted to the UK House of Lords, shared an article promoting saturation theory in late December that references the research. As of 9 January, his Twitter post had been shared 6,500 times and viewed 128,300 times.

Controversial Covid-19 treatment and vaccination research also received significant attention in 2024, with four of the most talked-about papers of the year – of any topic – retracted by journal editors.

The studies in question – three of which relate to vaccines and one to hydroxychloroquine – would have placed first, third, fourth and sixth in Altmetric’s overall rankings, had they not been withdrawn.

A controversial paper that did make it into the top 25 without being retracted was a study in the journal Geomatics. It argues that a decrease in planetary albedo and variations in “total solar irradiance” explain “100% of the global warming trend” over 2000-23 and 83% of interannual variability in global temperatures.

The authors have previously proposed a theory that global warming is caused by atmospheric pressure – and were caught publishing their papers under pseudonyms, which were their own names spelled backwards.

With only four news mentions, most of the attention from this article came from other sources. A tweet from the study’s lead author prompted a heated discussion and generated thousands of likes and retweets. Overall, the research was mentioned on Twitter 9,599 times.

The study, which came 13th in the overall rankings with a score of 2,096, was also mentioned on 14 blogs, including a number of climate-sceptic websites.

Elsewhere in the top 25

The rest of the top 25 contains a varied mix of papers that were typically well-received by the scientific community, including research on oil and gas system emissions (15th), mortality due to tropical cyclones in the US (16th) and the latest “state of wildfires” update (22nd). 

Paper number 12 finds that a “record-low planetary albedo”, mainly caused by low cloud cover in the northern mid-latitudes and tropics, may have been an important driver of the record-high global temperatures in 2023.

Published on 5 December in the journal Science, it is a relatively late entry into the annual rankings. Despite its late publication date, the study tops the charts for Bluesky mentions, gaining 376 mentions in less than one month.

A Communications Earth & Environment study, called “A recent surge in global warming is not detectable yet”, sits at number 21, with an Altmetric score of 2,018. The study uses statistical methods to search for a recent acceleration in global warming, and concludes that it is not possible to detect one.

The lead author of the study told Carbon Brief that the findings do not rule out that an acceleration might be occurring. She said that “the point of the paper is that it will take additional years of observations to detect a sustained acceleration”. However, some scientists questioned the utility of the methods used in the study, arguing there is evidence of an acceleration in warming.

At number 23 is a study in the journal Science which evaluates 1,500 climate policies that have been implemented over the past 25 years. The lead author of the study told Carbon Brief that taxes are “the only policy instrument that has been found to cause large emission reductions on their own”. The study received 30 mentions in blogs and more than 200 news mentions.

Some studies receive a lot of attention because they provoke discussion or a significant backlash, which drives up news stories and discussion on social media.

For example, the paper ranking at number 14 is a Nature Climate Change study claiming that the planet has already exceeded the 1.5C warming threshold set under the Paris Agreement.

The authors use proxy data from sea sponges in the Caribbean Sea to create a record of ocean temperatures from AD700 to the present day. They find that warming started 40 years before the IPCC’s pre-industrial baseline period began, and argue that this means “warming is 0.5C higher than [Intergovernmental Panel on Climate Change] estimates”.

However, many experts were critical, warning Carbon Brief that the framing of the study is misleading, and arguing that the finding has no bearing on the Paris Agreement 1.5C limit. One expert, who was also not involved in the study, said that “the way these findings have been communicated is flawed, and has the potential to add unnecessary confusion to public debate on climate change”.

The study received 262 news mentions, with some outlets – including the Guardian and New Scientist – highlighting the disagreements over the study’s framing.

All the final scores for the top 25 climate papers of 2024 can be found in this spreadsheet.

Top journals

Across the top 25 papers in Carbon Brief’s leaderboard this year, Nature features most frequently with seven papers. Nature is perennially high-placed in this analysis, taking first or joint first spot in Carbon Brief’s top 25 six times – 2021, 2020, 2019, 2018, 2017 and 2015.

In joint-second place this year are Science, Proceedings of the National Academy of Sciences and Communications Earth & Environment with three papers each.

Earth System Science Data has two papers, and there are seven journals that each have one paper.

Diversity of the top 25

The top 25 climate papers of 2024 cover a wide range of topics and scope. However, analysis of their authors reveals an all-too-familiar lack of diversity. Carbon Brief recorded the gender and country of affiliation for each of these authors. (The methodology used was developed by Carbon Brief for analysis presented in a special 2021 series on climate justice.)

In total, the top 25 climate papers of 2024 have 275 authors. This is fewer than in the past two years, partly due to the absence of the Lancet Countdown report, which typically has more than 100 authors.

The analysis reveals that the authors of the climate papers most featured in the media in 2024 are predominantly men from the global north.

The chart below shows the institutional affiliations of all authors in this analysis, broken down by continent – Europe, North America, Oceania, Asia, South America and Africa.

Chart: 85% of authors of the top 25 climate papers of 2024 are from Europe, North America and Oceania

The analysis shows that 85% of authors are affiliated with institutions from the global north – defined as North America, Europe and Oceania. Meanwhile, only two authors are from Africa.

Further data analysis shows that there are also inequalities within continents. The map below shows the percentage of authors from each country in the analysis, where dark blue indicates a higher percentage. Countries that are not represented by any authors in the analysis are shown in grey.

More than one-quarter of the top 25 climate papers of 2024 are from the US

The top-ranking countries on this map are the US and the UK, with 26% and 18% of the total authors, respectively. Germany ranks third on the list with 15% of the authors.

Meanwhile, only one-third of authors from the top 25 climate papers of 2024 are women. And only five of the 25 papers have a woman as a lead author.

The plot below shows the number of authors from each continent who are men (purple) and women (yellow).

Heatwaves driving recent ‘surge’ in compound drought and heat extremes

Published

on

Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows. 

Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.

The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.

The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.

The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.

Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.

One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.

Compound events

CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.

These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.

Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:

“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”

CDHEs can begin with either a heatwave or a drought.

The sequence of these extremes is important, the study says, as they have different drivers and impacts.

For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.

Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.

The study shows that the majority of CDHEs globally start out as a drought.

In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.

In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.

The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.

Increasing events

To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.

The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.

The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.

Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.

The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).

The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.

Threshold passed

The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.

In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.

The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.

This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.

Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.

In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.

Daily data

The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.

He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.

Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.

Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:

“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”

However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.

Compound impacts

The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.

These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.

Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.

The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.

Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:

“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”

DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine

Published

on

Welcome to Carbon Brief’s DeBriefed. 
An essential guide to the week’s key developments relating to climate change.

This week

Energy crisis

ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.

‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.

‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home News. This message was echoed by UK business secretary Peter Kyle, who said “doubling down on renewables” was “essential” amid “regional instability”, according to the Daily Telegraph.

China’s climate plan

PEAK COAL?: China has set out its next “five-year plan” at the annual “two sessions” meeting of the National People’s Congress, including its climate strategy out to 2030, according to the Hong Kong-based South China Morning Post. The plan called for China to cut its carbon emissions per unit of gross domestic product (GDP) by 17% from 2026 to 2030, which “may allow for continued increase in emissions given the rate of GDP growth”, reported Reuters. The newswire added that the plan also had targets to reach peak coal ​in the next five years and replace 30m tonnes per year of coal with renewables.

ACTIVE YET PRUDENT: Bloomberg described the new plan as “cautious”, stating that it “frustrat[es] hopes for tighter policy that would drive the nation to peak carbon emissions well before president Xi Jinping’s 2030 deadline”. Carbon Brief has just published an in-depth analysis of the plan. China Daily reported that the strategy “highlights measures to promote the climate targets of peaking carbon dioxide emissions before 2030”, which China said it would work towards “actively yet prudently”. 

Around the world

  • EU RULES: The European Commission has proposed new “made in Europe” rules to support domestic low-carbon industries, “against fierce competition from China”, reported Agence France-Presse. Carbon Brief examined what it means for climate efforts.

UK greenhouse gas emissions in 2025

UK greenhouse gas emissions in 2025 fell to 54% below 1990 levels, the baseline year for its legally binding climate goals, according to new Carbon Brief analysis. Over the same period, data from the World Bank shows that the UK’s economy has expanded by 95%, meaning that emissions have been decoupling from growth.

Bristol’s ‘pioneering’ community wind turbine

Following the recent launch of the UK government’s local power plan, Carbon Brief visits one of the country’s community-energy success stories.

The Lawrence Weston housing estate is set apart from the main city of Bristol, wedged between the tree-lined grounds of a stately home and a sprawl of warehouses and waste incinerators. It is one of the most deprived areas in the city.

Yet, just across the M5 motorway stands a structure that has brought the spoils of the energy transition directly to this historically forgotten estate – a 4.2 megawatt (MW) wind turbine.

The turbine is owned by local charity Ambition Lawrence Weston and all the profits from its electricity sales – around £100,000 a year – go to the community. In the UK’s local power plan, it was singled out by energy secretary Ed Miliband as a “pioneering” project.

‘Sustainable income’

On a recent visit to the estate by Carbon Brief, Ambition Lawrence Weston’s development manager, Mark Pepper, rattled off the story behind the wind turbine.

In 2012, Pepper and his team were approached by the Bristol Energy Cooperative with a chance to get a slice of the income from a new solar farm. They jumped at the opportunity.

Austerity measures were kicking in at the time,” Pepper told Carbon Brief. “We needed to generate an income. Our own, sustainable income.”

With the solar farm proving to be a success, the team started to explore other opportunities. This began a decade-long process that saw them navigate the Conservative government’s “ban” on onshore wind, raise £5.5m in funding and, ultimately, erect the turbine in 2023.

Today, the turbine generates electricity equivalent to Lawrence Weston’s 3,000 households and will save 87,600 tonnes of carbon dioxide (CO2) over its lifetime.

‘Climate by stealth’

Ambition Lawrence Weston’s hub is at the heart of the estate and the list of activities on offer is seemingly endless: birthday parties, kickboxing, a library, woodworking, help with employment and even a pop-up veterinary clinic. All supported, Pepper said, with the help of a steady income from community-owned energy.

The centre itself is kitted out with solar panels, heat pumps and electric-vehicle charging points, making it a living advertisement for the net-zero transition. Pepper noted that the organisation has also helped people with energy costs amid surging global gas prices.

Gesturing to the England flags dangling limply on lamp posts visible from the kitchen window, he said:

“There’s a bit of resentment around immigration and scarcity of materials and provision, so we’re trying to do our bit around community cohesion.”

This includes supper clubs and an interfaith grand iftar during the Muslim holy month of Ramadan.

Anti-immigration sentiment in the UK has often gone hand-in-hand with opposition to climate action. Right-wing politicians and media outlets promote the idea that net-zero policies will cost people a lot of money – and these ideas have cut through with the public.

Pepper told Carbon Brief he is sympathetic to people’s worries about costs and stressed that community energy is the perfect way to win people over:

“I think the only way you can change that is if, instead of being passive consumers…communities are like us and they’re generating an income to offset that.”

From the outset, Pepper stressed that “we weren’t that concerned about climate because we had other, bigger pressures”, adding:

“But, in time, we’ve delivered climate by stealth.”

Q&A: What does China’s 15th ‘five-year plan’ mean for climate change?

Published

on

China’s leadership has published a draft of its 15th five-year plan setting the strategic direction for the nation out to 2030, including support for clean energy and energy security.

The plan sets a target to cut China’s “carbon intensity” by 17% over the five years from 2026-30, but also changes the basis for calculating this key climate metric.

The plan continues to signal support for China’s clean-energy buildout and, in general, contains no major departures from the country’s current approach to the energy transition.

The government reaffirms support for several clean-energy industries, ranging from solar and electric vehicles (EVs) through to hydrogen and “new-energy” storage.

The plan also emphasises China’s willingness to steer climate governance and be seen as a provider of “global public goods”, in the form of affordable clean-energy technologies.

However, while the document says it will “promote the peaking” of coal and oil use, it does not set out a timeline and continues to call for the “clean and efficient” use of coal.

This shows that tensions remain between China’s climate goals and its focus on energy security, leading some analysts to raise concerns about its carbon-cutting ambition.

Below, Carbon Brief outlines the key climate change and energy aspects of the plan, including targets for carbon intensity, non-fossil energy and forestry.

Note: this article is based on a draft published on 5 March and will be updated if any significant changes are made in the final version of the plan, due to be released at the close next week of the “two sessions” meeting taking place in Beijing.

What is China’s 15th five-year plan?

Five-year plans are one of the most important documents in China’s political system.

Addressing everything from economic strategy to climate policy, they outline the planned direction for China’s socio-economic development in a five-year period. The 15th five-year plan covers 2026-30.

These plans include several “main goals”. These are largely quantitative indicators that are seen as particularly important to achieve and which provide a foundation for subsequent policies during the five-year period.

The table below outlines some of the key “main goals” from the draft 15th five-year plan.

Category Indicator Indicator in 2025 Target by 2030 Cumulative target over 2026-2030 Characteristic
Economic development Gross domestic product (GDP) growth (%) 5 Maintained within a reasonable range and proposed annually as appropriate. Anticipatory
‘Green and low-carbon Reduction in CO2 emissions per unit of GDP (%) 17.7 17 Binding
Share of non-fossil energy in total energy consumption (%) 21.7 25 Binding
Security guarantee Comprehensive energy production
capacity (100m tonnes of
standard coal equivalent)
51.3 58 Binding

Since the 12th five-year plan, covering 2011-2015, these “main goals” have included energy intensity and carbon intensity as two of five key indicators for “green ecology”.

The previous five-year plan, which ran from 2021-2025, introduced the idea of an absolute “cap” on carbon dioxide (CO2) emissions, although it did not provide an explicit figure in the document. This has been subsequently addressed by a policy on the “dual-control of carbon” issued in 2024.

The latest plan removes the energy-intensity goal and elevates the carbon-intensity goal, but does not set an absolute cap on emissions (see below).

It covers the years until 2030, before which China has pledged to peak its carbon emissions. (Analysis for Carbon Brief found that emissions have been “flat or falling” since March 2024.)

The plans are released at the two sessions, an annual gathering of the National People’s Congress (NPC) and the Chinese People’s Political Consultative Conference (CPPCC). This year, it runs from 4-12 March.

The plans are often relatively high-level, with subsequent topic-specific five-year plans providing more concrete policy guidance.

Policymakers at the National Energy Agency (NEA) have indicated that in the coming years they will release five sector-specific plans for 2026-2030, covering topics such as the “new energy system”, electricity and renewable energy.

There may also be specific five-year plans covering carbon emissions and environmental protection, as well as the coal and nuclear sectors, according to analysts.

Other documents published during the two sessions include an annual government work report, which outlines key targets and policies for the year ahead.

The gathering is attended by thousands of deputies – delegates from across central and local governments, as well as Chinese Communist party members, members of other political parties, academics, industry leaders and other prominent figures.

What does the plan say about China’s climate action?

Achieving China’s climate targets will remain a key driver of the country’s policies in the next five years, according to the draft 15th five-year plan.

It lists the “acceleration” of China’s energy transition as a “major achievement” in the 14th five-year plan period (2021-2025), noting especially how clean-power capacity had overtaken fossil fuels.

The draft says China will “actively and steadily advance and achieve carbon peaking”, with policymakers continuing to strike a balance between building a “green economy” and ensuring stability.

Climate and environment continues to receive its own chapter in the plan. However, the framing and content of this chapter has shifted subtly compared with previous editions, as shown in the table below. For example, unlike previous plans, the first section of this chapter focuses on China’s goal to peak emissions.

The climate and environment chapter in the latest plan calls for China to “balance [economic] development and emission reduction” and “ensure the timely achievement of carbon peak targets”.

Under the plan, China will “continue to pursue” its established direction and objectives on climate, Prof Li Zheng, dean of the Tsinghua University Institute of Climate Change and Sustainable Development (ICCSD), tells Carbon Brief.

What is China’s new CO2 intensity target?

In the lead-up to the release of the plan, analysts were keenly watching for signals around China’s adoption of a system for the “dual-control of carbon”.

This would combine the existing targets for carbon intensity – the CO2 emissions per unit of GDP – with a new cap on China’s total carbon emissions. This would mark a dramatic step for the country, which has never before set itself a binding cap on total emissions.

Policymakers had said last year that this framework would come into effect during the 15th five-year plan period, replacing the previous system for the “dual-control of energy”.

However, the draft 15th five-year plan does not offer further details on when or how both parts of the dual-control of carbon system will be implemented. Instead, it continues to focus on carbon intensity targets alone.

Looking back at the previous five-year plan period, the latest document says China had achieved a carbon-intensity reduction of 17.7%, just shy of its 18% goal.

This is in contrast with calculations by Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air (CREA), which had suggested that China had only cut its carbon intensity by 12% over the past five years.

At the time it was set in 2021, the 18% target had been seen as achievable, with analysts telling Carbon Brief that they expected China to realise reductions of 20% or more.

However, the government had fallen behind on meeting the target.

Last year, ecology and environment minister Huang Runqiu attributed this to the Covid-19 pandemic, extreme weather and trade tensions. He said that China, nevertheless, remained “broadly” on track to meet its 2030 international climate pledge of reducing carbon intensity by more than 65% from 2005 levels.

Myllyvirta tells Carbon Brief that the newly reported figure showing a carbon-intensity reduction of 17.7% is likely due to an “opportunistic” methodological revision. The new methodology now includes industrial process emissions – such as cement and chemicals – as well as the energy sector.

(This is not the first time China has redefined a target, with regulators changing the methodology for energy intensity in 2023.)

For the next five years, the plan sets a target to reduce carbon intensity by 17%, slightly below the previous goal.

However, the change in methodology means that this leaves space for China’s overall emissions to rise by “3-6% over the next five years”, says Myllyvirta. In contrast, he adds that the original methodology would have required a 2% fall in absolute carbon emissions by 2030.

The dashed lines in the chart below show China’s targets for reducing carbon intensity during the 12th, 13th, 14th and 15th five-year periods, while the bars show what was achieved under the old (dark blue) and new (light blue) methodology.

China reports meeting its latest carbon-intensity target after a change in methodology.
Dashed lines: China’s carbon-intensity targets during the 12th, 13th, 14th and 15th five-year plan periods. Bars: China’s achieved carbon-intensity reductions according to either the old methodology (dark blue) and the new one (light blue). The achieved reductions during the 12th and 13th five-year plans are from contemporaneous government statistics and may be revised in future. The reduction figures for the 14th five-year plan period are sourced from government statistics for the new methodology and analysis by CREA under the old methodology. Sources: Five-year plans and Carbon Brief.

The carbon-intensity target is the “clearest signal of Beijing’s climate ambition”, says Li Shuo, director at the Asia Society Policy Institute’s (ASPI) China climate hub.

It also links directly to China’s international pledge – made in 2021 – to cut its carbon intensity to more than 65% below 2005 levels by 2030.

To meet this pledge under the original carbon-intensity methodology, China would have needed to set a target of a 23% reduction within the 15th five-year plan period. However, the country’s more recent 2035 international climate pledge, released last year, did not include a carbon-intensity target.

As such, ASPI’s Li interprets the carbon-intensity target in the draft 15th five-year plan as a “quiet recalibration” that signals “how difficult the original 2030 goal has become”.

Furthermore, the 15th five-year plan does not set an absolute emissions cap.

This leaves “significant ambiguity” over China’s climate plans, says campaign group 350 in a press statement reacting to the draft plan. It explains:

“The plan was widely expected to mark a clearer transition from carbon-intensity targets toward absolute emissions reductions…[but instead] leaves significant ambiguity about how China will translate record renewable deployment into sustained emissions cuts.”

Myllyvirta tells Carbon Brief that this represents a “continuation” of the government’s focus on scaling up clean-energy supply while avoiding setting “strong measurable emission targets”.

He says that he would still expect to see absolute caps being set for power and industrial sectors covered by China’s emissions trading scheme (ETS). In addition, he thinks that an overall absolute emissions cap may still be published later in the five-year period.

Despite the fact that it has yet to be fully implemented, the switch from dual-control of energy to dual-control of carbon represents a “major policy evolution”, Ma Jun, director of the Institute of Public and Environmental Affairs (IPE), tells Carbon Brief. He says that it will allow China to “provide more flexibility for renewable energy expansion while tightening the net on fossil-fuel reliance”.

Does the plan encourage further clean-energy additions?

“How quickly carbon intensity is reduced largely depends on how much renewable energy can be supplied,” says Yao Zhe, global policy advisor at Greenpeace East Asia, in a statement.

The five-year plan continues to call for China’s development of a “new energy system that is clean, low-carbon, safe and efficient” by 2030, with continued additions of “wind, solar, hydro and nuclear power”.

In line with China’s international pledge, it sets a target for raising the share of non-fossil energy in total energy consumption to 25% by 2030, up from just under 21.7% in 2025.

The development of “green factories” and “zero-carbon [industrial] parks” has been central to many local governments’ strategies for meeting the non-fossil energy target, according to industry news outlet BJX News. A call to build more of these zero-carbon industrial parks is listed in the five-year plan.

Prof Pan Jiahua, dean of Beijing University of Technology’s Institute of Ecological Civilization, tells Carbon Brief that expanding demand for clean energy through mechanisms such as “green factories” represents an increasingly “bottom-up” and “market-oriented” approach to the energy transition, which will leave “no place for fossil fuels”.

He adds that he is “very much sure that China’s zero-carbon process is being accelerated and fossil fuels are being driven out of the market”, pointing to the rapid adoption of EVs.

The plan says that China will aim to double “non-fossil energy” in 10 years – although it does not clarify whether this means their installed capacity or electricity generation, or what the exact starting year would be.

Research has shown that doubling wind and solar capacity in China between 2025-2035 would be “consistent” with aims to limit global warming to 2C.

While the language “certainly” pushes for greater additions of renewable energy, Yao tells Carbon Brief, it is too “opaque” to be a “direct indication” of the government’s plans for renewable additions.

She adds that “grid stability and healthy, orderly competition” is a higher priority for policymakers than guaranteeing a certain level of capacity additions.

China continues to place emphasis on the need for large-scale clean-energy “bases” and cross-regional power transmission.

The plan says China must develop “clean-energy bases…in the three northern regions” and “integrated hydro-wind-solar complexes” in south-west China.

It specifically encourages construction of “large-scale wind and solar” power bases in desert regions “primarily” for cross-regional power transmission, as well as “major hydropower” projects, including the Yarlung Tsangpo dam in Tibet.

As such, the country should construct “power-transmission corridors” with the capacity to send 420 gigawatts (GW) of electricity from clean-energy bases in western provinces to energy-hungry eastern provinces by 2030, the plan says.

State Grid, China’s largest grid operator, plans to install “another 15 ultra-high voltage [UHV] transmission ​lines” by 2030, reports Reuters, up from the 45 UHV lines built by last year.

Below are two maps illustrating the interlinkages between clean-energy bases in China in the 15th (top) and 14th (bottom) five-year plan periods.

The yellow dotted areas represent clean energy bases, while the arrows represent cross-regional power transmission. The blue wind-turbine icons represent offshore windfarms and the red cooling tower icons represent coastal nuclear plants.

The 15th five-year plan map shows a consistent approach to the 2021-2025 period. As well as power being transmitted from west to east, China plans for more power to be sent to southern provinces from clean-energy bases in the north-west, while clean-energy bases in the north-east supply China’s eastern coast.

It also maps out “mutual assistance” schemes for power grids in neighbouring provinces.

Offshore wind power should reach 100GW by 2030, while nuclear power should rise to 110GW, according to the plan.

What does the plan signal about coal?

The increased emphasis on grid infrastructure in the draft 15th five-year plan reflects growing concerns from energy planning officials around ensuring China’s energy supply.

Ren Yuzhi, director of the NEA’s development and planning department, wrote ahead of the plan’s release that the “continuous expansion” of China’s energy system has “dramatically increased its complexity”.

He said the NEA felt there was an “urgent need” to enhance the “secure and reliable” replacement of fossil-fuel power with new energy sources, as well as to ensure the system’s “ability to absorb them”.

Meanwhile, broader concerns around energy security have heightened calls for coal capacity to remain in the system as a “ballast stone”.

The plan continues to support the “clean and efficient utilisation of fossil fuels” and does not mention either a cap or peaking timeline for coal consumption.

Xi had previously told fellow world leaders that China would “strictly control” coal-fired power and phase down coal consumption in the 15th five-year plan period.

The “geopolitical situation is increasing energy security concerns” at all levels of government, said the Institute for Global Decarbonization Progress in a note responding to the draft plan, adding that this was creating “uncertainty over coal reduction”.

Ahead of its publication, there were questions around whether the plan would set a peaking deadline for oil and coal. An article posted by state news agency Xinhua last month, examining recommendations for the plan from top policymakers, stated that coal consumption would plateau from “around 2027”, while oil would peak “around 2026”.

However, the plan does not lay out exact years by which the two fossil fuels should peak, only saying that China will “promote the peaking of coal and oil consumption”.

There are similarly no mentions of phasing out coal in general, in line with existing policy.

Nevertheless, there is a heavy emphasis on retrofitting coal-fired power plants. The plan calls for the establishment of “demonstration projects” for coal-plant retrofitting, such as through co-firing with biomass or “green ammonia”.

Such retrofitting could incentivise lower utilisation of coal plants – and thus lower emissions – if they are used to flexibly meet peaks in demand and to cover gaps in clean-energy output, instead of providing a steady and significant share of generation.

The plan also calls for officials to “fully implement low-carbon retrofitting projects for coal-chemical industries”, which have been a notable source of emissions growth in the past year.

However, the coal-chemicals sector will likely remain a key source of demand for China’s coal mining industry, with coal-to-oil and coal-to-gas bases listed as a “key area” for enhancing the country’s “security capabilities”.

Meanwhile, coal-fired boilers and industrial kilns in the paper industry, food processing and textiles should be replaced with “clean” alternatives to the equivalent of 30m tonnes of coal consumption per year, it says.

“China continues to scale up clean energy at an extraordinary pace, but the plan still avoids committing to strong measurable constraints on emissions or fossil fuel use”, says Joseph Dellatte, head of energy and climate studies at the Institut Montaigne. He adds:

“The logic remains supply-driven: deploy massive amounts of clean energy and assume emissions will eventually decline.”

Back to top

How will China approach global climate governance in the next five years?

Meanwhile, clean-energy technologies continue to play a role in upgrading China’s economy, with several “new energy” sectors listed as key to its industrial policy.

Named sectors include smart EVs, “new solar cells”, new-energy storage, hydrogen and nuclear fusion energy.

“China’s clean-technology development – rather than traditional administrative climate controls – is increasingly becoming the primary driver of emissions reduction,” says ASPI’s Li. He adds that strengthening China’s clean-energy sectors means “more closely aligning Beijing’s economic ambitions with its climate objectives”.

Analysis for Carbon Brief shows that clean energy drove more than a third of China’s GDP growth in 2025, representing around 11% of China’s whole economy.

The continued support for these sectors in the draft five-year plan comes as the EU outlined its own measures intended to limit China’s hold on clean-energy industries, driven by accusations of “unfair competition” from Chinese firms.

China is unlikely to crack down on clean-tech production capacity, Dr Rebecca Nadin, director of the Centre for Geopolitics of Change at ODI Global, tells Carbon Brief. She says:

“Beijing is treating overcapacity in solar and smart EVs as a strategic choice, not a policy error…and is prepared to pour investment into these sectors to cement global market share, jobs and technological leverage.”

Dellatte echoes these comments, noting that it is “striking” that the plan “barely addresses the issue of industrial overcapacity in clean technologies”, with the focus firmly on “scaling production and deployment”.

At the same time, China is actively positioning itself to be a prominent voice in climate diplomacy and a champion of proactive climate action.

This is clear from the first line in a section on providing “global public goods”. It says:

“As a responsible major country, China will play a more active role in addressing global challenges such as climate change.”

The plan notes that China will “actively participate in and steer [引领] global climate governance”, in line with the principle of “common,but differentiated responsibilities”.

This echoes similar language from last year’s government work report, Yao tells Carbon Brief, demonstrating a “clear willingness” to guide global negotiations. But she notes that this “remains an aspiration that’s yet to be made concrete”. She adds:

“China has always favored collective leadership, so its vision of leadership is never a lone one.”

The country will “deepen south-south cooperation on climate change”, the plan says. In an earlier section on “opening up”, it also notes that China will explore “new avenues for collaboration in green development” with global partners as part of its “Belt and Road Initiative”.

China is “doubling down” on a narrative that it is a “responsible major power” and “champion of south-south climate cooperation”, Nadin says, such as by “presenting its clean‑tech exports and finance as global public goods”. She says:

“China will arrive at future COPs casting itself as the indispensable climate leader for the global south…even though its new five‑year plan still puts growth, energy security and coal ahead of faster emissions cuts at home.”

Back to top

What else does the plan cover?

The impact of extreme weather – particularly floods – remains a key concern in the plan.

China must “refine” its climate adaptation framework and “enhance its resilience to climate change, particularly extreme-weather events”, it says.

China also aims to “strengthen construction of a national water network” over the next five years in order to help prevent floods and droughts.

An article published a few days before the plan in the state-run newspaper China Daily noted that, “as global warming intensifies, extreme weather events – including torrential rains, severe convective storms, and typhoons – have become more frequent, widespread and severe”.

The plan also touches on critical minerals used for low-carbon technologies. These will likely remain a geopolitical flashpoint, with China saying it will focus during the next five years on “intensifying” exploration and “establishing” a reserve for critical minerals. This reserve will focus on “scarce” energy minerals and critical minerals, as well as other “advantageous mineral resources”.

Dellatte says that this could mean the “competition in the energy transition will increasingly be about control over mineral supply chains”.

Other low-carbon policies listed in the five-year plan include expanding coverage of China’s mandatory carbon market and further developing its voluntary carbon market.

China will “strengthen monitoring and control” of non-CO2 greenhouse gases, the plan says, as well as implementing projects “targeting methane, nitrous oxide and hydrofluorocarbons” in sectors such as coal mining, agriculture and chemicals.

This will create “capacity” for reducing emissions by 30m tonnes of CO2 equivalent, it adds.

Meanwhile, China will develop rules for carbon footprint accounting and push for internationally recognised accounting standards.

It will enhance reform of power markets over the next five years and improve the trading mechanism for green electricity certificates.

It will also “promote” adoption of low-carbon lifestyles and decarbonisation of transport, as well as working to advance electrification of freight and shipping.
