Key developments
Clean-energy industry drives China growth in 2023
CLEANTECH BOOM: New analysis for Carbon Brief found that clean-energy sectors – spanning low-carbon power, grids, energy storage, electric vehicles (EVs) and railways – contributed 11.4tn yuan ($1.6tn) to China’s economy in 2023, accounting for “all of the growth in Chinese investment and a larger share of economic growth than any other part of the economy”. This was driven, in particular, by the “new three” industries of solar power, EVs and batteries. Investment totalled 6.3tn yuan ($890bn), growing 40% year-on-year and almost equalling all global investments in fossil fuel supply last year – or the entire economies of Switzerland or Turkey.
GDP BOOST: Clean-energy sectors accounted for 40% of the expansion of GDP in 2023, the analysis showed. Without this contribution, China’s GDP would have risen only by 3% instead of 5.2% – well below the growth target set for 2023. This makes the industry not only crucial for China’s energy transition, but also for “broader economic and industrial” development, found the analysis.
OVERCAPACITY CONCERNS: However, the analysis continued, “the spectre of overcapacity means China’s clean-energy investment growth…cannot continue indefinitely”, adding that “the manufacturing expansion has already saturated most of the global market”. In related news, Jiemian reported exports of the “new three” industries reached more than 1tn yuan ($141bn). This has seen the EU, among others, take steps to support their own clean-energy industries, reported Agence France-Presse, adding that Chinese premier Li Qiang recently held “frank” talks with European Commission president Ursula von der Leyen on trade imbalances.
China relaunched voluntary carbon market
RESUMED TRADING: State-run broadcaster CCTV reported that China’s voluntary carbon-trading system, the China Certified Emission Reduction (CCER) programme, resumed trading on 22 January. CCER’s relaunch “marks the completion of China’s domestic carbon-market architecture”, the broadcaster added. Beijing News described CCER as an “institutional innovation to mobilise the power of the whole society to participate in greenhouse gas emission reduction actions”.
NEW CREDITS?: Economic outlet Jiemian said that CCER project registration was suspended in 2017. It reported that “preparation on the policy end” for restarting issuance of carbon credits under the scheme is “almost complete”, pending the “state administration for market regulation (SAMR)…releas[ing] the list of recognised validation and verification institutions”. The scale of new CCER issuance is predicted to be between tens of millions to 100m tonnes per year, according to one analyst, the newspaper adds.
INCLUDED SCOPE: Finance news outlet EastMoney reported that the greenhouse gas trading under the scheme is primarily open to enterprises or institutions in four major sectors: “afforestation carbon sinks, grid-connected solar-thermal power generation, grid-connected offshore wind power generation and mangrove plantation”. It may in future allow individuals “to sell carbon emissions generated from green behaviours under the CCER scheme…as the trading mechanism matures”, according to the South China Morning Post.
Tasks, measures and timelines for ‘Beautiful China’
BEAUTIFUL CHINA: The top bodies of the Chinese government and governing Communist party – the state council and the central committee, respectively – issued the full text of new instructions on “comprehensively promoting the construction of a Beautiful China” in a 27 December official release, published by state news agency Xinhua on 11 January. The Beautiful China initiative is a “top-level development blueprint detailing specific targets for…the nation’s green and high-quality growth”, another Xinhua report explained. ClientEarth’s Dimitri De Boer wrote in China Dialogue that the initiative “ties a good environment to a sense of national pride”.
KEY GOALS: The document outlined a slew of tasks, measures and timelines within China’s overall push to peak its carbon emissions before 2030 and reach carbon neutrality by 2060. By 2027, “green and low-carbon development” will be “further promoted”, it said. By 2035, “green production methods and lifestyles will be widely formed”. By the middle of the century, “ecological civilisation will be comprehensively upgraded…[with] deep decarbonisation achieved in key areas”. Goals listed in the document include: the country will compile an annual national greenhouse gas inventory; “gradually shift” to “dual control” of carbon emissions; protect more than 3.15m square kilometres of land from being eligible for development projects under the national ecological “red line” policy; ensure China’s cities become “waste-free” by 2035; and see new energy vehicles (NEVs, mostly electric vehicles) comprise around 45% of new cars by 2027.
OFFICIAL COMMENT: The document was passed in a meeting chaired by Chinese president Xi Jinping, who said that “building a Beautiful China is an important goal for building a modern socialist country”, the state-run China Daily reported – giving the document more weight and signalling to officials that China’s carbon-neutrality goals remain an important target. Adding to the momentum, following its publication, Sun Jinlong and Huang Runqiu – the Communist party secretary and the minister at the ministry of ecology and environment (MEE), respectively – wrote an opinion piece in the Communist party-backed newspaper People’s Daily saying that the document “clearly defines the overall requirements, key tasks and major initiatives” guiding the Beautiful China initiative. In an interview with Xinhua, a senior official of the MEE said incentives and policy measures could “mobilise enthusiasm, initiative and creativity” to build a Beautiful China.
US and China climate envoys step down
KERRY RETIRES: US climate envoy John Kerry plans to retire from his role in the next few months, in order “to help President Biden’s [re-election] campaign”, Axios reported. In stepping back from “a major diplomatic role that was created especially for him”, the New York Times reported, Kerry casts the position into “an uncertain future”. The fact that he has chosen to do so following the retirement of Chinese climate envoy Xie Zhenhua “[raises] concerns about what climate diplomacy will look [like]” without their cooperative personal dynamic, it added.
END OF AN ERA: Xie and Kerry “have a close personal relationship”, Climate Home News reported, adding that “Xie’s return from retirement in 2021 was widely interpreted as a response to Kerry’s appointment [to the climate envoy role]”. “If Kerry and Xie weren’t in office…there’s no way we’d be even close to where we’re at,” the Financial Times quoted Jake Schmidt, a senior director at thinktank NRDC, saying. It also reported that Kerry said he and Xie were “doing all we can to stay in very close touch; and he and I will continue to work in respective institutions [to forge collaboration on climate change]”.
NEW BLOOD: Career diplomat Liu Zhenmin – profiled in Carbon Brief’s DeBriefed newsletter – will become China’s new climate envoy, Reuters reported. The newswire added that Liu has “long experience in climate diplomacy”, participating in both the Kyoto Protocol and Paris Agreement negotiations. Liu “was a key driver in landing the Kyoto Protocol”, Greenpeace East Asia chief China representative Yuan Ying told Carbon Brief, which is “a promising piece of experience”. However, Climate Home News quoted an anonymous analyst as saying “many experts wanted someone from the environment ministry appointed”, as “[the foreign ministry] approaches climate as a card in US-China [manoeuvring]” instead of seeing it “as a real issue that needs to be solved”.

Interview with Prof Zou Ji, CEO and president of the Energy Foundation China

At COP28, Carbon Brief sat down with Prof Zou Ji, CEO and president of the Energy Foundation China, to discuss China’s energy transition.
Prof Zou previously served as a deputy director-general of China’s National Center for Climate Change Strategy and International Cooperation.
He was part of China’s negotiation team for the Paris Agreement and a lead author of several Intergovernmental Panel on Climate Change assessment reports.
Below are highlights from the wide-ranging conversation, covering China’s stance on coal, renewables, issues-based alliances and more. The full interview will be published on the Carbon Brief website soon.
China’s decisions at COP28
On signing pledges at COP: “If you look at the whole history of the COP…I do not [remember] China joining any alliances. I have never seen that…As a party, China [is only concerned with] official procedures, waiting for a legal framework of the UNFCCC or the Paris Agreement.”
On why China did not join the pledge to triple renewables and double efficiency: “[Before COP28] we have not seen [it laid out] very clearly which year should be the base year [from which tripling renewables should be calculated]. Should it be 2020? Should it be 2022? This might seem to be technical but, [in] the past two years, global development of renewables, especially in China, [have been significantly boosted, and so]…the difference in targets might be very significant.”
On China’s commitment to decarbonisation: “If you look back at history, there have been very few cases that show China [first making] and then [giving up] a commitment. This is not the political culture in China.”
The future of coal
On fossil fuel phaseout: “I would like to see…[China] very quickly enlarging its renewable capacity. Only if [there is] adequate capacity and generation of renewables can this lead to a real phasing out or phasing down of fossil fuels.”
On others’ views of required coal capacity: “Even though China will reach its [2060] carbon neutrality target, it will continue to have to maintain 600 gigawatts of coal-fired power plant capacity. These are the sort of estimations [we’re working with now].” (Prof Zou disagrees with this, believing that renewables growth, better grid connectivity and increased energy storage capacity should reduce the need for such a large amount of coal capacity.)
On the need for CCUS: “In some sectors, like, for example, iron and steel, cement, chemicals and petrochemicals, we do need carbon capture, utilisation and storage (CCUS), because it is very difficult to phase out coal or carbon dioxide [completely].”
On CCUS in the power sector: “I have mixed feelings about CCUS for the power sector. I have an ideal vision that we can reach real zero emissions in these sectors through a more developed grid system, with more connectivity across provinces or regions and the use of AI technology.”
Transitioning to renewable energy
On ensuring more renewables uptake: “We have raised the share of renewable power generation from seven, eight, nine per cent to today’s 16%. This is progress, but it is not quick enough or large enough. We want to push the grid companies…to do more and do it faster.”
On the power of distributed solar: “We should also consider…creat[ing] another, totally new power system. This would be a sort of nexus of a centralised and decentralised grid system…If [the central grid] is having difficulties [increasing renewable generation], and if these are very challenging to overcome, then let’s [shift] to a lot of microgrids.”
On distributed solar growth: “Today, the share of distributed [renewables] is still lower than centralised renewables. But the incremental [distributed] renewables growth has become higher than growth of centralised renewables in the past year or two, and I would assume this will remain a trend in the future.”
Measuring energy use
On China’s electricity consumption: “For low-income level groups, although their income has not grown very much, their consumption preferences and mindsets – especially for younger generations of consumers – mean they are more willing to use electricity [than previous generations].”
On comparisons of China to the EU and US: “There is a structural [difference] compared to the [energy mix] in Europe and the US. The majority of energy use [in China] has been for industrial production, rather than for residential [use]…In China, the average power consumption per capita is around 6,000 kilowatt-hours (kWh), compared to 8,000kWh in Europe and over 12,000kWh in the US.”
On energy efficiency: “Physically, I think China has become better and better [in terms of] its efficiency, but, economically, this cannot produce as high a value-add as Europe and the US in monetary terms.”
On challenges calculating carbon intensity: “The raising of interest rates by the US Federal Reserve makes US dollars more expensive, increasing foreign exchange rates which then enlarges the monetary GDP gap making Chinese GDP [in dollar terms] fall, and carbon intensity rise.”
Watch, read, listen
FOSSIL FUEL HIGHS: Clyde Russell, Asia commodities and energy columnist at Reuters, wrote that, although China’s crude oil and coal imports “all soared to record highs in 2023”, crude oil is likely being added to inventories rather than being used, while the spike in coal is a temporary response to hydropower shortages.
ROSEWOOD DEFORESTATION: The China-Global South Project spoke to Ma Haibing, Asia policy specialist at the Environmental Investigation Agency, about illegal harvesting of rosewood by Chinese traders in the “rapidly shrinking forests” of west Africa.
GREEN SHOOTS: Yicai interviewed Zhang Xiaoqiang, executive vice-president of the China Center for International Economic Exchanges (CCIEE), on prospects for “green” development in China in 2024, the growth of renewables, cross-provincial power transmission and other topics.
ANTARCTIC RESEARCH: CCTV broadcasted a short news report on the progress of the 40th Chinese Antarctic research expedition in building China’s newest research station in Antarctica.
New science
Drought-related wildfire accounts for one-third of the forest wildfires in subtropical China
Agricultural and Forest Meteorology
A new study found that “drought plays a dominant role” in wildfires in subtropical China, adding that “from 2001 to 2020, excess wildfires caused by drought accounted for approximately 31% of the total number of forest fire points during the fire season (November to May)”. As the drying trend caused by climate change intensifies, wildfires will “show different patterns due to the large differences in the sensitivity of wildfire to drought in subtropical China”, it added.
Bulletin of the American Meteorological Society
Human-caused climate change made the August 2022 heatwave in southern China 50% hotter than it would have been without global warming, according to new research. The heatwave, the researchers noted, was “extraordinary and unprecedented”, being the “longest-lasting and most intense [China has seen] since 1961”. The study also found that, although it was focused on southern China, “the main conclusions also apply to the eastern Tibetan plateau”.
Potential for CO2 storage in shale basins in China
International Journal of Greenhouse Gas Control
Researchers used the latest data to calculate new “potentials of [carbon dioxide (CO2)] storage in major shale gas/oil basins in China”, driven by the fact that China, as the second largest shale gas and oil producing country, possesses “large and significant” shale basins. They found that China could sequester approximately 6,194bn tonnes of CO2 in shale basins, equivalent to 620 years’ of China’s projected carbon emissions.

Key developments
Food inflation on the rise
DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.
‘TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.
El Niño looms
NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”
WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”
CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.
News and views
- DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
- SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
- NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted.
- COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
- FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.”
- TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.

Nature talks inch forward
This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.
The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.
The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).
However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.
The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.
Money talks
Finance for nature has long been a sticking point at negotiations under the CBD.
Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.
Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.
Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).
Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:
“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”
Monitoring and reporting
Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.
Parties do so through the submission of national reports.
Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.
A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.
Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:
“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”

Dangerous heat for Tour de France riders only a ‘question of time’
Rising temperatures across France since the mid-1970s is putting Tour de France competitors at “high risk”, according to new research.
The study, published in Scientific Reports, uses 50 years of climate data to calculate the potential heat stress that athletes have been exposed to across a dozen different locations during the world-famous cycling race.
The researchers find that both the severity and frequency of high-heat-stress events have increased across France over recent decades.
But, despite record-setting heatwaves in France, the heat-stress threshold for safe competition has rarely been breached in any particular city on the day the Tour passed through.
(This threshold was set out by cycling’s international governing body in 2024.)
However, the researchers add it is “only a question of time” until this occurs as average temperatures in France continue to rise.
The lead author of the study tells Carbon Brief that, while the race organisers have been fortunate to avoid major heat stress on race days so far, it will be “harder and harder to be lucky” as extreme heat becomes more common.
‘Iconic’
The Tour de France is one of the world’s most storied cycling races and the oldest of Europe’s three major multi-week cycling competitions, or Grand Tours.
Riders cover around 3,500 kilometres (km) of distance and gain up to nearly 55km of altitude over 21 stages, with only two or three rest days throughout the gruelling race.
The researchers selected the Tour de France because it is the “iconic bike race. It is the bike race of bike races,” says Dr Ivana Cvijanovic, a climate scientist at the French National Research Institute for Sustainable Development, who led the new work.
Heat has become a growing problem for the competition in recent years.
In 2022, Alexis Vuillermoz, a French competitor, collapsed at the finish line of the Tour’s ninth stage, leaving in an ambulance and subsequently pulling out of the race entirely.
Two years later, British cyclist Sir Mark Cavendish vomited on his bike during the first stage of the race after struggling with the 36C heat.
The Tour also makes a good case study because it is almost entirely held during the month of July and, while the route itself changes, there are many cities and stages that are repeated from year to year, Cvijanovic adds.
‘Have to be lucky’
The study focuses on the 50-year span between 1974 and 2023.
The researchers select six locations across the country that have commonly hosted the Tour, from the mountain pass of Col du Tourmalet, in the French Pyrenees, to the city of Paris – where the race finishes, along the Champs-Élysées.
These sites represent a broad range of climatic zones: Alpe d’ Huez, Bourdeaux, Col du Tourmalet, Nîmes, Paris and Toulouse.
For each location, they use meteorological reanalysis data from ERA5 and radiant temperature data from ERA5-HEAT to calculate the “wet-bulb globe temperature” (WBGT) for multiple times of day across the month of July each year.
WBGT is a heat-stress index that takes into account temperature, humidity, wind speed and direct sunlight.
Although there is “no exact scientific consensus” on the best heat-stress index to use, WBGT is “one of the rare indicators that has been originally developed based on the actual human response to heat”, Cvijanovic explains.
It is also the one that the International Cycling Union (UCI) – the world governing body for sport cycling – uses to assess risk. A WBGT of 28C or higher is classified as “high risk” by the group.
WBGT is the “gold standard” for assessing heat stress, says Dr Jessica Murfree, director of the ACCESS Research Laboratory and assistant professor at the University of North Carolina at Chapel Hill.
Murfree, who was not involved in the new study, adds that the researchers are “doing the right things by conducting their science in alignment with the business practices that are already happening”.
The researchers find that across the 50-year time period, WBGT has been increasing across the entire country – albeit, at different rates. In the north-west of the country, WBGT has increased at an average rate of 0.1C per decade, while in the southern and eastern parts of the country, it has increased by more than 0.5C per decade.
The maps below show the maximum July WBGT for each decade of the analysis (rows) and for hourly increments of the late afternoon (columns). Lower temperatures are shown in lighter greens and yellows, while higher temperatures are shown in darker reds and purples.
Six Tour de France locations analysed in the study are shown as triangles on the maps (clockwise from top): Paris, Alpe d’ Huez, Nîmes, Toulouse, Col du Tourmalet and Bordeaux.
The maps show that the maximum WBGT temperature in the afternoon has surpassed 28C over almost the entire country in the last decade. The notable exceptions to this are the mountainous regions of the Alps and the Pyrenees.
The researchers also find that most of the country has crossed the 28C WBGT threshold – which they describe as “dangerous heat levels” – on at least one July day over the past decade. However, by looking at the WBGT on the day the Tour passed through any of these six locations, they find that the threshold has rarely been breached during the race itself.
For example, the research notes that, since 1974, Paris has seen a WBGT of 28C five times at 3pm in July – but that these events have “so far” not coincided with the cycling race.
The study states that it is “fortunate” that the Tour has so far avoided the worst of the heat-stress.
Cvijanovic says the organisers and competitors have been “lucky” to date. She adds:
“It has worked really well for them so far. But as the frequency of these [extreme heat] events is increasing, it will be harder and harder to be lucky.”
Dr Madeleine Orr, an assistant professor of sport ecology at the University of Toronto who was not involved in the study, tells Carbon Brief that the paper was “really well done”, noting that its “methods are good [and its] approach was sound”. She adds:
“[The Tour has] had athletes complain about [the heat]. They’ve had athletes collapse – and still those aren’t the worst conditions. I think that that says a lot about what we consider safe. They’ve still been lucky to not see what unsafe looks like, despite [the heat] having already had impacts.”
Heat safety protocols
In 2024, the UCI set out its first-ever high temperature protocol – a set of guidelines for race organisers to assess athletes’ risk of heat stress.
The assessment places the potential risk into one of five categories based on the WBGT, ranging from very low to high risk.
The protocol then sets out suggested actions to take in the event of extreme heat, ranging from having athletes complete their warm-ups using ice vests and cold towels to increasing the number of support vehicles providing water and ice.
If the WBGT climbs above the 28C mark, the protocol suggests that organisers modify the start time of the stage, adapt the course to remove particularly hazardous sections – or even cancel the race entirely.
However, Orr notes that many other parts of the race, such as spectator comfort and equipment functioning, may have lower temperatures thresholds that are not accounted for in the protocol, but should also be considered.
Murfree points out that the study’s findings – and the heat protocol itself – are “really focused on adaptation, rather than mitigation”. While this is “to be expected”, she tells Carbon Brief:
“Moving to earlier start times or adjusting the route specifically to avoid these locations that score higher in heat stress doesn’t stop the heat stress. These aren’t climate preventative measures. That, I think, would be a much more difficult conversation to have in the research because of the Tour de France’s intimate relationship with fossil-fuel companies.”

DeBriefed 20 February 2026: EU’s ‘3C’ warning | Endangerment repeal’s impact on US emissions | ‘Tree invasion’ fuelled South America’s fires
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Preparing for 3C
NEW ALERT: The EU’s climate advisory board urged countries to prepare for 3C of global warming, reported the Guardian. The outlet quoted Maarten van Aalst, a member of the advisory board, saying that adapting to this future is a “daunting task, but, at the same time, quite a doable task”. The board recommended the creation of “climate risk assessments and investments in protective measures”.
‘INSUFFICIENT’ ACTION: EFE Verde added that the advisory board said that the EU’s adaptation efforts were so far “insufficient, fragmented and reactive” and “belated”. Climate impacts are expected to weaken the bloc’s productivity, put pressure on public budgets and increase security risks, it added.
UNDERWATER: Meanwhile, France faced “unprecedented” flooding this week, reported Le Monde. The flooding has inundated houses, streets and fields and forced the evacuation of around 2,000 people, according to the outlet. The Guardian quoted Monique Barbut, minister for the ecological transition, saying: “People who follow climate issues have been warning us for a long time that events like this will happen more often…In fact, tomorrow has arrived.”
IEA ‘erases’ climate
MISSING PRIORITY: The US has “succeeded” in removing climate change from the main priorities of the International Energy Agency (IEA) during a “tense ministerial meeting” in Paris, reported Politico. It noted that climate change is not listed among the agency’s priorities in the “chair’s summary” released at the end of the two-day summit.
US INTERVENTION: Bloomberg said the meeting marked the first time in nine years the IEA failed to release a communique setting out a unified position on issues – opting instead for the chair’s summary. This came after US energy secretary Chris Wright gave the organisation a one-year deadline to “scrap its support of goals to reduce energy emissions to net-zero” – or risk losing the US as a member, according to Reuters.

Captured

Repealing the US’s landmark “endangerment finding”, along with actions that rely on that finding, will slow the pace of US emissions cuts, according to Rhodium Group visualised by Carbon Brief. US president Donald Trump last week formally repealed the scientific finding that underpins federal regulations on greenhouse gas emissions, although the move is likely to face legal challenges. Data from the Rhodium Group, an independent research firm, shows that US emissions will drop more slowly without climate regulations. However, even with climate regulations, emissions are expected to drop much slower under Trump than under the previous Joe Biden administration, according to the analysis.

How a ‘tree invasion’ helped to fuel South America’s fires
This week, Carbon Brief explores how the “invasion” of non-native tree species helped to fan the flames of forest fires in Argentina and Chile earlier this year.
Since early January, Chile and Argentina have faced large-scale and deadly wildfires, including in Patagonia, which spans both countries.
These fires have been described as “some of the most significant and damaging in the region”, according to a World Weather Attribution (WWA) analysis covered by Carbon Brief.
In both countries, the fires destroyed vast areas of native forests and grasslands, displacing thousands of people. In Chile, the fires resulted in 23 deaths.

Multiple drivers contributed to the spread of the fires, including extended periods of high temperatures, low rainfall and abundant dry vegetation.
The WWA analysis concluded that human-caused climate change made these weather conditions at least three times more likely.
According to the researchers, another contributing factor was the invasion of non-native trees in the regions where the fires occurred.
The risk of non-native forests
In Argentina, the wildfires began on 6 January and persisted until the first week of February. They hit the city of Puerto Patriada and the Los Alerces and Lago Puelo national parks, in the Chubut province, as well as nearby regions.
In these areas, more than 45,000 hectares of native forests – such as Patagonian alerce tree, myrtle, coigüe and ñire – along with scrubland and grasslands, were consumed by the flames, according to the WWA study.
In Chile, forest fires occurred from 17 to 19 January in the Biobío, Ñuble and Araucanía regions.
The fires destroyed more than 40,000 hectares of forest and more than 20,000 hectares of non-native forest plantations, including eucalyptus and Monterey pine.
Dr Javier Grosfeld, a researcher at Argentina’s National Scientific and Technical Research Council (CONICET) in northern Patagonia, told Carbon Brief that these species, introduced to Patagonia for production purposes in the late 20th century, grow quickly and are highly flammable.
Because of this, their presence played a role in helping the fires to spread more quickly and grow larger.
However, that is no reason to “demonise” them, he stressed.
Forest management
For Grosfeld, the problem in northern Patagonia, Argentina, is a significant deficit in the management of forests and forest plantations.
This management should include pruning branches from their base and controlling the spread of non-native species, he added.
A similar situation is happening in Chile, where management of pine and eucalyptus plantations is not regulated. This means there are no “firebreaks” – gaps in vegetation – in place to prevent fire spread, Dr Gabriela Azócar, a researcher at the University of Chile’s Centre for Climate and Resilience Research (CR2), told Carbon Brief.
She noted that, although Mapuche Indigenous communities in central-south Chile are knowledgeable about native species and manage their forests, their insight and participation are not recognised in the country’s fire management and prevention policies.
Grosfeld stated:
“We are seeing the transformation of the Patagonian landscape from forest to scrubland in recent years. There is a lack of preventive forestry measures, as well as prevention and evacuation plans.”
