Snapshot
EV INVESTIGATION: China deemed the “formal” launch of the EU’s investigation into Chinese subsidies for electric vehicles as a “naked act of protectionism”, but refrained from making similarly strong public remarks during a visit from EU trade commissioner Valdis Dombrovskis.
DOUBLING NUCLEAR: The China Nuclear Energy Association said China can greenlight six to eight new nuclear power units a year, with the technology’s share of electricity doubling to 10% by 2035 and then 18% by 2060.
TREE RULES: China reformed communal forest tenure systems to encourage environmental protection and provide another revenue stream for low-income rural households. The rules could encourage the development of carbon sinks – or increase logging activity.
SPOTLIGHT: As China’s “belt and road initiative” celebrates its tenth anniversary, Carbon Brief asked four experts what it could mean for climate action in the decade ahead.
NEW SCIENCE: Studies found that citizens experience relatively limited levels of “energy justice” under China’s implementation of energy transition policies and, separately, that there were “substantial health co-benefits” from residential decarbonisation, particularly in northern China.
Key developments
EU split over Chinese EV probe
EV SPLIT: The European Commission has “formally launched” an anti-subsidies probe into electric vehicles manufactured in China, a process that should last one year, reported Bloomberg. The investigation was triggered by a request from France, according to the Hong-Kong based news outlet the South China Morning Post (SCMP). France has already changed “eligibility rules” to “make sure French state cash is not benefiting Chinese carmakers”, reported Reuters. But German chancellor Olaf Scholz has opposed the commission’s move on the grounds that “our economic model should not be based or rely on protectionism”, reported another Reuters article. The bloc’s solar, wind and battery manufacturers have also sought support to compete against cheap Chinese competition, reported SCMP. German-language business newspaper Handelsblatt said the EU plans policies to make its wind industry more competitive with Chinese manufacturers.
CHINA’S REACTION: Beijing repeated its “strong dissatisfaction” with the investigation, calling it “a naked act of protectionism”, reported state news agency Xinhua. However, Bloomberg noted that China did not “publicly” share that criticism during commission executive vice-president Valdis Dombrovskis’ four-day trip to the country, shying away from confrontation amid “a broader push to stabilise geopolitical relationships [and] an economic slowdown at home”. Another Bloomberg article said that Tesla will be a significant focus of the EU investigation, having “enjoyed perks in China that other international companies struggled to obtain”. Elsewhere, Xie Zhenhua, China’s special envoy for climate change, “stressed the importance of opposing trade protectionism” at a summit in China, reported CGTN, a state-affiliated Chinese media outlet. The Communist party-backed People’s Daily published a commentary under the “Zhongyin” byline – a nom de plume for top party leadership – saying the fact that “more than 60% of the world’s new energy vehicles are produced and sold in China” was an example of the country’s economic dynamism.
METALS SCRAP: Meanwhile, debate continues over China’s dominance of critical mineral supply chains, with the Financial Times reporting comments by US energy secretary Jennifer Granholm saying the situation could make the global energy transition “infinitely more complex”. China’s export of germanium, used for making solar panels and other technologies, fell to “zero” in August after the government imposed export controls, reported TechSpot. At the same time, China has told local EV companies to procure chips and other components domestically to “set up a self-sufficient EV supply chain”, reported DigiTimes Asia. However, Reuters reported that US firm AXT and a number of unnamed Chinese firms had received export licences in September for “gallium and germanium products” for certain customers.
Growing role for nuclear
10% BY 2035: Nuclear power’s share is expected to double to 10% of China’s electricity by 2035 and then grow to 18% by 2060, with installed capacity climbing from 57 gigawatts (GW) today to 400GW by 2060, according to the China Nuclear Energy Association (CNEA), Reuters reported. The outlet said China expected to approve “six to eight new nuclear power units” every year from now on. The state-run newspaper China Daily quoted Wang Binghua, the director of CNEA’s nuclear energy public communication committee, as telling the Paper: “In the context of achieving both the carbon goals and ensuring economic growth, nuclear energy has demonstrated its irreplaceable advantages.” According to the outlet, he said reaching the 10% projection would cut carbon dioxide (CO2) emissions by about 920m tonnes over this period. (For more background, see Carbon Brief’s Q&A: How China is using nuclear power to reduce its carbon emissions.)
SHIFTING VIEWS: Meanwhile, China Daily published comments made in a speech by International Atomic Energy Agency (IAEA) director general Rafael Grossi, who said that the public’s view towards nuclear energy has shifted. He stated that the “emergency” brought about by climate change was “undeniable” and that nuclear energy could play a “positive role” as part of the solution. “In the past few years, we have not been vocal enough about the benefits of nuclear power, but that page has been turned,” he added.
New forestry rules
CARBON SINKS: China released a plan to reform its communal forest tenure system in order to “enhance farmers’ incomes and promote green growth”, reported state news media CGTN. One aim of the plan is to “improve forest quality”, the outlet said, adding that “green industries, such as ecological tourism, maintaining healthy forests and environmental education” will be established. Business news outlet 21st Century Daily noted in an opinion column that the plan “encourages eligible places to carry out forestry carbon sink projects and establish a forestry carbon sink trading market”. The Legal Daily reported that the measures call for provinces to “strengthen the supply capacity of important primary forest products…and encourage provinces, cities and counties with forest resources to cultivate forestry ‘pillar industries’”. In an email to subscribers, consultancy Trivium China said the reforms could lead to greater logging activity.
CCER TRADING: Meanwhile, business news outlet Jiemian published comments by experts on the inclusion of forestry carbon sinks in China’s certified voluntary emission reductions scheme (CCERs). They explained some of the risks involved in the scheme, including guarding against oversupply, filling “legal gaps” in the policy framework and finalising mechanisms for distributing the proceeds of credit sales.
China’s ‘key role’ at COP28
CLIMATE DIPLOMACY: COP28 president-designate Sultan Ahmed Al Jaber wrote in an opinion article for state news agency Xinhua that China will play a “key role” in delivering on a COP28 agenda that “aims at fast-tracking an equitable and orderly energy transition, fixing climate finance, and focusing on people’s lives and livelihoods, while underpinning everything with full inclusivity”. He added that China is critical both for “driving clean energy adoption” in the global south and for supplying funding to support other developing nations’ energy transitions. Separately, China News quoted Zhang Jun, China’s permanent representative to the United Nations, as saying that China’s climate actions stand in sharp contrast to the “empty promises” of western nations. Elsewhere, Foreign Policy said foreign minister Wang Yi is expected to travel to the US in October to manage their “increasingly frosty relations” and to “pave the way for a highly anticipated, but still unscheduled meeting between US president Joe Biden and Chinese president Xi Jinping”.
COAL CONTINUES: Meanwhile, speaking at a forum in Beijing, China’s climate envoy Xie Zhenhua said that the “complete phasing-out of fossil fuels is not realistic”, reported Reuters. This came as Hong Kong-based South China Morning Post covered a report from energy consultancy Rystad Energy finding that “China will increase its coal consumption until 2026 and will only record declines after 2027”.
Spotlight
How will China’s belt and road initiative impact climate action?
China will host the third Belt and Road Forum for International Cooperation this month, as “2023 mark[s] the 10th anniversary of the belt and road initiative (BRI)”, Reuters reported. More than 110 countries are set to attend.
The BRI is a global infrastructure project that aims to develop transcontinental trade routes between China and the rest of the world. With China having stated an intention to pivot the initiative towards low-carbon energy development, Carbon Brief asks leading experts what impact the BRI might have on climate action in the decade ahead. Their responses have been edited for clarity and length.
Prof Kevin P Gallagher, director of the Boston University Global Development Policy Center:
As the BRI moves into its second decade, China can solidify its pivot toward low-carbon development in the global south. According to our research at the Boston University Global Development Policy Center, in the early stages of the BRI the majority of China’s overseas energy finance was…in fossil fuels in general and coal-fired power plants in particular. Emissions from the operating Chinese-financed power plants around the world now emit upwards of 245m tonnes of CO2 annually, roughly the energy-related CO2 emissions from the entire country of Spain or Thailand annually. In 2021, China announced it would not build new coal-fired power projects abroad and to step up support for low-carbon development. Moving forward, China could pledge to ramp up overseas financing for low carbon development and adopt a green project pipeline facility to ensure alignment with these directives.
Prof Lin Boqiang, dean of the China Institute for Studies in Energy Policy, Xiamen University:
In some countries along the “belt and road”, despite the rapid growth of energy demand, the development of green energy is limited due to their relatively backward economic and technological level and the lack of advanced clean-energy technology and facilities. Through the construction of renewable energy projects, such as wind and solar power, China can provide technical, financial and experience support to host countries to promote the development and upgrading of their renewable energy industries. By providing more clean-energy supplies to these countries…China helps them reduce their dependence on traditional energy sources and promotes energy transformation and green development. At the same time, some countries along the belt and road have problems such as unstable energy supply, energy poverty and low energy efficiency…Cooperation to develop renewable energy projects…will help these countries improve their energy security and promote sustainable development along the belt and road.
Yasiru Ranaraja, founding director of the Belt and Road Initiative Sri Lanka (BRISL)
China’s commitment to shift the BRI towards low-carbon energy development has significant implications for climate action in the coming decade…China, through the BRI, has emerged as a crucial player in advocating a three-phase approach to low-carbon development: funding, construction and operation. Under the BRI umbrella, numerous infrastructure projects…are dedicated to green development…For example, in Sri Lanka, the Colombo International Container Terminal (CICT), which is an investment development project under BRI, has embraced green technology since its inception in 2014.
This terminal has witnessed a remarkable increase in cargo volumes over the years while prioritising environmental sustainability. The shift to electric cranes has resulted in a 45% reduction in CO2 emissions and a 95% decrease in diesel consumption…Additionally, more than 80% of the terminal’s electricity comes from solar technology. The terminal’s success story…exemplifies how commercial prosperity and environmental protection can coexist harmoniously.
Prof Christoph Nedopil Wang, director of the Griffith Asia Institute, Griffith University:
China controls almost all parts of the green-energy supply chain – from critical minerals for batteries to wafer production for solar, from manufacturing wind turbines to the necessary financing. Without China’s cooperation, a green-energy transition is hardly achievable – whether in the BRI or beyond…BRI countries, meanwhile, must improve their energy planning, energy policy and power markets to be able to attract sufficient Chinese investments in green energy. This should include a phase-down of fossil subsidies and better utilisation of blended finance to reduce financing cost for green energies, as well as longer-term green energy PPAs (power purchase agreements). A big question remains on the accelerated phase-down of Chinese sponsored coal-fired power plants and replacement with green energy. A recent study by the Green Finance & Development Center and Climate Smart Ventures shows significant financial benefits for Chinese sponsors of plants in Vietnam and Pakistan when accelerating retirement and replacement.
Watch, read, listen
PEAK OIL: The Financial Times explored the tension that exists between China’s role as the largest global consumer of oil and the minor role that oil plays in China’s energy mix, following comments by the chief executive of one of China’s largest oil companies that “perhaps this year China’s domestic oil demand will reach a peak”.
CRITICAL MINERALS: In the third part of a series on China and energy geopolitics, the Oxford Institute for Energy Studies discussed China’s importance for the critical minerals used in new energy supply chains and what its dominance could mean for the future.
METHANE RESEARCH: The Woodrow Wilson Center interviewed Dr Hu Tao, founder of the Lakestone Institute for Sustainable Development, on his institute’s work on methane mitigation from food waste and manure in China, as well as on his views on how China’s voluntary carbon credit scheme (CCERs) could mitigate agricultural methane.
MARKET MECHANISMS: Caixin published part of the upcoming report on China’s “carbon neutral strategy and path selection”, written by the Boao Forum for Asia Academy. The report advocates improving market mechanisms to support a “just” energy transition, such as research investment, carbon markets, power grid pricing and funding non-renewable “clean” energy solutions.

Costs and health benefits of the rural energy transition to carbon neutrality in China
Nature Communications
A study found that residential decarbonisation “would remarkably improve air quality in northern China, yielding substantial health co-benefits”. Decarbonising rural cooking and heating, the researchers added, “would triple contemporary energy consumption from 2014 to 2060”, which would considerably reduce energy poverty in China. The effects would be most strongly felt in Shandong, Heilongjiang, Shanxi and Hebei provinces.
Assessing energy justice in climate change policies: an empirical examination of China’s energy transition
Climate Policy
A new study explored “key aspects of energy transition policy implementation in China” through the lens of distributional, recognition and procedural justice. From a case study assessing China’s ‘coal-to-gas’ energy transition policy in rural regions, it found a “markedly low” level of procedural justice, linked to poor access to political participation and low transparency. It also found “insufficient acknowledgment of the needs of specific groups” during the energy transition. By contrast, the level of distributional justice, defined as equitable allocation of benefits, was “reasonably high”.

What Is the Economic Impact of Data Centers? It’s a Secret.
N.C. Gov. Josh Stein wants state lawmakers to rethink tax breaks for data centers. The industry’s opacity makes it difficult to evaluate costs and benefits.
Tax breaks for data centers in North Carolina keep as much as $57 million each year into from state and local government coffers, state figures show, an amount that could balloon to billions of dollars if all the proposed projects are built.

GEF raises $3.9bn ahead of funding deadline, $1bn below previous budget
The Global Environment Facility (GEF), a multilateral fund that provides climate and nature finance to developing countries, has raised $3.9 billion from donor governments in its last pledging session ahead of a key fundraising deadline at the end of May.
The amount, which is meant to cover the fund’s activities for the next four years (July 2026-June 2030), falls significantly short of the previous four-year cycle for which the GEF managed to raise $5.3bn from governments. Since then, military and other political priorities have squeezed rich nations’ budgets for climate and development aid.
The facility said in a statement that it expects more pledges ahead of the final replenishment package, which is set for approval at the next GEF Council meeting from May 31 to June 3.
Claude Gascon, interim CEO of the GEF, said that “donor countries have risen to the challenge and made bold commitments towards a more positive future for the planet”. He added that the pledges send a message that “the world is not giving up on nature even in a time of competing priorities”.
Donors under pressure
But Brian O’Donnell, director of the environmental non-profit Campaign for Nature, said the announcement shows “an alarming trend” of donor governments cutting public finance for climate and nature.
“Wealthy nations pledged to increase international nature finance, and yet we are seeing cuts and lower contributions. Investing in nature prevents extinctions and supports livelihoods, security, health, food, clean water and climate,” he said. “Failing to safeguard nature now will result in much larger costs later.”
At COP29 in Baku, developed countries pledged to mobilise $300bn a year in public climate finance by 2035, while at UN biodiversity talks they have also pledged to raise $30bn per year by 2030. Yet several wealthy governments have announced cuts to green finance to increase defense spending, among them most recently the UK.
As for the US, despite Trump’s cuts to international climate finance, Congress approved a $150 million increase in its contribution to the GEF after what was described as the organisation’s “refocus on non-climate priorities like biodiversity, plastics and ocean ecosystems, per US Treasury guidance”.
The facility will only reveal how much each country has pledged when its assembly of 186 member countries meets in early June. The last period’s largest donors were Germany ($575 million), Japan ($451 million), and the US ($425 million).
The GEF has also gone through a change in leadership halfway through its fundraising cycle. Last December, the GEF Council asked former CEO Carlos Manuel Rodriguez to step down effective immediately and appointed Gascon as interim CEO.

New guidelines
As part of the upcoming funding cycle, the GEF has approved a set of guidelines for spending the $3.9bn raised so far, which include allocating 35% of resources for least developed countries and small island states, as well as 20% of the money going to Indigenous people and communities.
Its programs will help countries shift five key systems – nature, food, urban, energy and health – from models that drive degradation to alternatives that protect the planet and support human well-being by integrating the value of nature into production and consumption systems.
The new priorities also include a target to allocate 25% of the GEF’s budget for mobilising private funds through blended finance. This aligns with efforts by wealthy countries to increase contributions from the private sector to international climate finance.
Niels Annen, Germany’s State Secretary for Economic Cooperation and Development, said in a statement that the country’s priorities are “very well reflected” in the GEF’s new spending guidelines, including on “innovative finance for nature and people, better cooperation with the private sector, and stable resources for the most vulnerable countries”.
Aliou Mustafa, of the GEF Indigenous Peoples Advisory Group (IPAG), also welcomed the announcement, adding that “the GEF is strengthening trust and meaningful partnerships with Indigenous Peoples and local communities” by placing them at the “centre of decision-making”.

Marine heatwaves ‘nearly double’ the economic damage caused by tropical cyclones
Tropical cyclones that rapidly intensify when passing over marine heatwaves can become “supercharged”, increasing the likelihood of high economic losses, a new study finds.
Such storms also have higher rates of rainfall and higher maximum windspeeds, according to the research.
The study, published in Science Advances, looks at the economic damages caused by nearly 800 tropical cyclones that occurred around the world between 1981 and 2023.
It finds that rapidly intensifying tropical cyclones that pass near abnormally warm parts of the ocean produce nearly double – 93% – the economic damages as storms that do not, even when levels of coastal development are taken into account.
One researcher, who was not involved in the study, tells Carbon Brief that the new analysis is a “step forward in understanding how we can better refine our predictions of what might happen in the future” in an increasingly warm world.
As marine heatwaves are projected to become more frequent under future climate change, the authors say that the interactions between storms and these heatwaves “should be given greater consideration in future strategies for climate adaptation and climate preparedness”.
‘Rapid intensification’
Tropical cyclones are rapidly rotating storm systems that form over warm ocean waters, characterised by low pressure at their cores and sustained winds that can reach more than 120 kilometres per hour.
The term “tropical cyclones” encompasses hurricanes, cyclones and typhoons, which are named as such depending on which ocean basin they occur in.
When they make landfall, these storms can cause major damage. They accounted for six of the top 10 disasters between 1900 and 2024 in terms of economic loss, according to the insurance company Aon’s 2025 climate catastrophe insight report.
These economic losses are largely caused by high wind speeds, large amounts of rainfall and damaging storm surges.
Storms can become particularly dangerous through a process called “rapid intensification”.
Rapid intensification is when a storm strengthens considerably in a short period of time. It is defined as an increase in sustained wind speed of at least 30 knots (around 55 kilometres per hour) in a 24-hour period.
There are several factors that can lead to rapid intensification, including warm ocean temperatures, high humidity and low vertical “wind shear” – meaning that the wind speeds higher up in the atmosphere are very similar to the wind speeds near the surface.
Rapid intensification has become more common since the 1980s and is projected to become even more frequent in the future with continued warming. (Although there is uncertainty as to how climate change will impact the frequency of tropical cyclones, the increase in strength and intensification is more clear.)
Marine heatwaves are another type of extreme event that are becoming more frequent due to recent warming. Like their atmospheric counterparts, marine heatwaves are periods of abnormally high ocean temperatures.
Previous research has shown that these marine heatwaves can contribute to a cyclone undergoing rapid intensification. This is because the warm ocean water acts as a “fuel” for a storm, says Dr Hamed Moftakhari, an associate professor of civil engineering at the University of Alabama who was one of the authors of the new study. He explains:
“The entire strength of the tropical cyclone [depends on] how hot the [ocean] surface is. Marine heatwave means we have an abundance of hot water that is like a gas [petrol] station. As you move over that, it’s going to supercharge you.”
However, the authors say, there is no global assessment of how rapid intensification and marine heatwaves interact – or how they contribute to economic damages.
Using the International Best Track Archive for Climate Stewardship (IBTrACS) – a database of tropical cyclone paths and intensities – the researchers identify 1,600 storms that made landfall during the 1981-2023 period, out of a total of 3,464 events.
Of these 1,600 storms, they were able to match 789 individual, land-falling cyclones with economic loss data from the Emergency Events Database (EM-DAT) and other official sources.
Then, using the IBTrACS storm data and ocean-temperature data from the European Centre for Medium-Range Weather Forecasts, the researchers classify each cyclone by whether or not it underwent rapid intensification and if it passed near a recent marine heatwave event before making landfall.
The researchers find that there is a “modest” rise in the number of marine heatwave-influenced tropical cyclones globally since 1981, but with significant regional variations. In particular, they say, there are “clear” upward trends in the north Atlantic Ocean, the north Indian Ocean and the northern hemisphere basin of the eastern Pacific Ocean.
‘Storm characteristics’
The researchers find substantial differences in the characteristics of tropical cyclones that experience rapid intensification and those that do not, as well as between rapidly intensifying storms that occur with marine heatwaves and those that occur without them.
For example, tropical cyclones that do not experience rapid intensification have, on average, maximum wind speeds of around 40 knots (74km/hr), whereas storms that rapidly intensify have an average maximum wind speed of nearly 80 knots (148km/hr).
Of the rapidly intensifying storms, those that are influenced by marine heatwaves maintain higher wind speeds during the days leading up to landfall.
Although the wind speeds are very similar between the two groups once the storms make landfall, the pre-landfall difference still has an impact on a storm’s destructiveness, says Dr Soheil Radfar, a hurricane-hazard modeller at Princeton University. Radfar, who is the lead author of the new study, tells Carbon Brief:
“Hurricane damage starts days before the landfall…Four or five days before a hurricane making landfall, we expect to have high wind speeds and, because of that high wind speed, we expect to have storm surges that impact coastal communities.”
They also find that rapidly intensifying storms have higher peak rainfall than non-rapidly intensifying storms, with marine heatwave-influenced, rapidly intensifying storms exhibiting the highest average rainfall at landfall.
The charts below show the mean sustained wind speed in knots (top) and the mean rainfall in millimetres per hour (bottom) for the tropical cyclones analysed in the study in the five days leading up to and two days following a storm making landfall.
The four lines show storms that: rapidly intensified with the influence of marine heatwaves (red); those that rapidly intensified without marine heatwaves (purple); those that experienced marine heatwaves, but did not rapidly intensify (orange); and those that neither rapidly intensified nor experienced a marine heatwave (blue).

Dr Daneeja Mawren, an ocean and climate consultant at the Mauritius-based Mascarene Environmental Consulting who was not involved in the study, tells Carbon Brief that the new study “helps clarify how marine heatwaves amplify storm characteristics”, such as stronger winds and heavier rainfall. She notes that this “has not been done on a global scale before”.
However, Mawren adds that other factors not considered in the analysis can “make a huge difference” in the rapid intensification of tropical cyclones, including subsurface marine heatwaves and eddies – circular, spinning ocean currents that can trap warm water.
Dr Jonathan Lin, an atmospheric scientist at Cornell University who was also not involved in the study, tells Carbon Brief that, while the intensification found by the study “makes physical sense”, it is inherently limited by the relatively small number of storms that occur. He adds:
“There’s not that many storms, to tease out the physical mechanisms and observational data. So being able to reproduce this kind of work in a physical model would be really important.”
Economic costs
Storm intensity is not the only factor that determines how destructive a given cyclone can be – the economic damages also depend strongly on the population density and the amount of infrastructure development where a storm hits. The study explains:
“A high storm surge in a sparsely populated area may cause less economic damage than a smaller surge in a densely populated, economically important region.”
To account for the differences in development, the researchers use a type of data called “built-up volume”, from the Global Human Settlement Layer. Built-up volume is a quantity derived from satellite data and other high-resolution imagery that combines measurements of building area and average building height in a given area. This can be used as a proxy for the level of development, the authors explain.
By comparing different cyclones that impacted areas with similar built-up volumes, the researchers can analyse how rapid intensification and marine heatwaves contribute to the overall economic damages of a storm.
They find that, even when controlling for levels of coastal development, storms that pass through a marine heatwave during their rapid intensification cause 93% higher economic damages than storms that do not.
They identify 71 marine heatwave-influenced storms that cause more than $1bn (inflation-adjusted across the dataset) in damages, compared to 45 storms that cause those levels of damage without the influence of marine heatwaves.
This quantification of the cyclones’ economic impact is one of the study’s most “important contributions”, says Mawren.
The authors also note that the continued development in coastal regions may increase the likelihood of tropical cyclone damages over time.
Towards forecasting
The study notes that the increased damages caused by marine heatwave-influenced tropical cyclones, along with the projected increases in marine heatwaves, means such storms “should be given greater consideration” in planning for future climate change.
For Radfar and Moftakhari, the new study emphasises the importance of understanding the interactions between extreme events, such as tropical cyclones and marine heatwaves.
Moftakhari notes that extreme events in the future are expected to become both more intense and more complex. This becomes a problem for climate resilience because “we basically design in the future based on what we’ve observed in the past”, he says. This may lead to underestimating potential hazards, he adds.
Mawren agrees, telling Carbon Brief that, in order to “fully capture the intensification potential”, future forecasts and risk assessments must account for marine heatwaves and other ocean phenomena, such as subsurface heat.
Lin adds that the actions needed to reduce storm damages “take on the order of decades to do right”. He tells Carbon Brief:
“All these [planning] decisions have to come by understanding the future uncertainty and so this research is a step forward in understanding how we can better refine our predictions of what might happen in the future.”
