Key developments
Huang reported to lawmakers on climate action
NPCSC REPORT: Huang Runqiu, head of the Ministry of Ecology and Environment, told Chinese lawmakers that managing the country’s carbon dioxide (CO2) intensity has become “more challenging” due to the effects of the Covid-19 pandemic, extreme weather and growing trade tensions, Bloomberg reported. According to the full text of Huang’s remarks, made during a report to the National People’s Congress (NPC) Standing Committee, the minister remarked that China’s progress on meeting the target is “broadly in line” with its current international climate pledge for 2030. [Its CO2 intensity target for 2025 is likely to be missed.] He added that challenges have worsened around balancing climate action with economic development, managing “overall and local interests” and “aligning short-term with medium-to-long-term goals”.
TARGETS ‘SURPASSED’: Huang also highlighted the progress China had made in other areas, having “already surpassed” targets for wind and solar power capacity additions and new forest stock volume, the state-run newspaper China Daily said. According to current affairs outlet China News, Huang also noted that China has continued its “efforts to enhance the clean and efficient utilisation of fossil fuels”, including “reforms” for coal-fired power plants and “steadily increasing” gas production and utilisation.
GLOBAL INFLUENCE: China is “making important contributions to the implementation of the Paris Agreement”, Huang also said, according to the full text of his remarks, having “driven substantial reductions in the costs of wind and solar power” and “advanced international cooperation on climate change”, such as in south-south collaboration. He noted that in the face of “uncertainties”, such as the US withdrawal from the Paris Agreement and the expansion of the EU’s carbon border adjustment mechanism, China will enhance its “influence, guidance and shaping power in global climate governance”.
Movements ahead of UNGA
COP30 SIGNALS: Former climate envoy Xie Zhenhua travelled with Huang to Brussels to meet EU climate lead Teresa Ribera on 16 September, Reuters reported, in order to restart “climate negotiations” ahead of the UN general assembly and COP30. It added that current climate envoy Liu Zhenmin was not expected to be present. (A photo posted on Bluesky confirmed Xie’s presence in the city.) A few days earlier, COP30 executive director Ana Toni met Huang in Beijing, where he told her that China will support Brazil in hosting a COP that “sends a strong signal” about the importance of the Paris Agreement, climate news outlet Tanpaifang reported. Toni told reporters that Brazil expects a “huge Chinese delegation” at COP, the Global Times said. She also spoke at an event at Tsinghua University attended by Xie and followed online by Carbon Brief.
UK-CHINA: Meanwhile, the UK and China established a new industrial decarbonisation working group, according to a UK government statement, focusing on areas including carbon capture, utilisation and storage. Daniel Brooker, the head of the China office at UK Research and Innovation, told finance news outlet Yicai that climate cooperation with China is “one of our immediate priorities”.
INTERCONNECTED WORLD: Separately, vice-president Han Zheng used a conference speech to urge other countries to cooperate on developing “renewable energy generation, grid interconnectivity and smart energy systems” as a way of advancing the global energy transition, according to the Communist party-affiliated newspaper People’s Daily.
First auction under new renewable pricing system
LOWER PRICES: Shandong province held the country’s first renewable power auction, following the launch of new rules for the pricing of wind and solar power, industry news outlet BJX News reported, with the auction price of wind power set at 0.319 yuan per kilowatt-hour (yuan/kWh) and those for solar set at 0.225 yuan/kWh. The low prices set by the “bellwether” province signalled that “renewables prices [across China] in the future will be lower than under the previous system”, Reuters said, adding that it could “discourage” further investment. On LinkedIn, David Fishman, principal at the Lantau Group, said that while the wind power prices would likely be acceptable for developers, the solar prices would be “very tough”, citing one as saying they would likely “abandon” all future projects in the province.

PLANS ‘PROMPT’: Meanwhile, the National Energy Administration (NEA) urged local governments during a video conference to “promptly” release their plans for implementing the pricing reforms, energy news outlet International Energy Net said, to “stabilise” industry expectations. Separately, the NEA revealed during the conference that, between January and July 2025, China’s installed renewable energy capacity grew by 283 gigawatts (GW) to 2,171GW, current affairs outlet China News reported. In August, BJX News said, thermal-power generation grew by 1.7% – slower than July’s growth rate – while wind power grew by just over 20%, solar grew by 16% and hydropower fell by 10%.
LOCALISED PROJECTS: The NEA also co-released a notice on “improving pricing mechanisms” for localised new-energy projects, International Energy Net reported, referring to projects that “both generate and consume electricity” such as zero-carbon industrial parks. The notice outlined benchmarks for how much of their own renewable energy such projects should sell and consume, clarifying that such projects should “bear transmission and distribution fees, system operation costs and other expenses”, it added.
China set targets for new AI energy projects
AI PILOTS: China plans to increase the use of AI in the country’s energy sector, state news agency Xinhua reported, in order to “enhance energy security, improve operational efficiency and support the country’s green and low-carbon transition”. China will “promote the deep application of at least five specialised large models”, which could be used in the power grid, power generation, coal, oil, gas or other areas, according to industry news outlet China Energy News. It also reported that China plans to identify ten or more “replicable, scalable and competitive” pilot projects. Consulting firm Trivium China wrote in a note that the plan “positions AI as an indispensable tool” on climate change.
DOUBLING STORAGE: China aims to “almost double” new-energy storage capacity by 2027 to 180GW, according to a new industry plan, Reuters reported. Lithium-ion battery storage is likely to comprise the bulk of new additions, economic news outlet Jiemian said. Meanwhile, according to a new government action plan for 2025-2026, new-energy power equipment companies are expected to achieve “steady” annual revenue increase, while traditional power equipment firms should aim to grow “approximately 6%” and “leading” companies by 10%, Xinhua said.
POLICY WATCH: China adopted the atomic energy law, its first foundational law for the nuclear sector, Jiemian reported. China’s environmental code – also the first of its kind – remains under discussion, according to China News. Elsewhere, the country updated its plan to “advance the three-north shelterbelt forest programme”, China Daily said. The National Development and Reform Commission called for “exploring” pathways for real estate investment trusts to invest in ultra-high voltage transmission projects, BJX News reported. BJX News also covered new guidance on improving electricity spot markets.
Spotlight
Q&A: Will China and the BRICS fill the ‘leadership gap’ on climate change?
Amid a rapidly fracturing geopolitical order, there have been growing calls for China to “step into [the] leadership gap” left by the US on climate change.
One platform that it could use to do so is BRICS, an increasingly influential and assertive group that includes COP30 host Brazil.
In this issue, Carbon Brief explores whether or not China, alongside the BRICS, could become climate leaders. The full article is available on Carbon Brief’s website.
The BRICS group represents a number of emerging economies that aim to “increas[e] the influence of global south countries in international governance”.
Active full members include founding members Brazil, Russia, India and China, as well as South Africa, Egypt, the United Arab Emirates, Ethiopia, Indonesia and Iran.
Together, they represent 27% of global gross domestic product, 49% of the world’s population and 52% of carbon dioxide emissions, according to Carbon Brief calculations.
Four of the members – Brazil, China, India and South Africa – also form the BASIC bloc, a group with a significant voice at UN climate summits and other negotiations.
How do the BRICS approach climate change?
Lucas Carlos Lima, professor of international law at the Federal University of Minas Gerais in Brazil, wrote that recent joint statements show the BRICS had “placed climate change squarely at the centre of the bloc’s agenda”.
In July, the BRICS summit resulted in a joint declaration demanding that “accessible, timely and affordable climate finance” is provided to developing countries.
The statement also highlighted the nations’ “resolve to remain united in the pursuit of the purpose and goals of the Paris Agreement”.
However, the BRICS leaders’ declaration also “acknowledge[s] fossil fuels will still play an important role in the world’s energy mix”.
The inclusion of this language “undermin[es] the positives” of the bloc’s other statements on climate action, according to a response from Jacobo Ocharan, head of political strategies at Climate Action Network International.
What is the role of fossil fuels in the BRICS?
Many BRICS nations remain heavily reliant on fossil fuels, both for electricity generation and to support their wider energy systems.
However, this picture is starting to shift, with almost all BRICS members having adopted net-zero targets ranging from 2050 to 2070.
More tangibly, the addition of new clean-power projects means that fossil-fueled electricity generating capacity now makes up less than half of the installed total in the BRICS group as a whole in 2024, as shown in the figure below.
Non-fossil power, driven by “unprecedented” renewable energy growth in China, India and Brazil, accounted for 53% of the installed electricity generating capacity in BRICS countries in 2024, according to thinktank Global Energy Monitor (GEM).
Continued BRICS focus on clean energy makes it “unlikely that fossil capacity will overtake non-fossil again”, James Norman, research analyst at GEM, told Carbon Brief.
Several BRICS members, including Russia, the UAE, Iran and Indonesia, are nevertheless leading producers and exporters of fossil fuels.
China and India, meanwhile, are by some distance the world’s largest and second-largest coal users, respectively.
Nevertheless, in the short term, this might not affect the BRICS group’s climate ambition overall.
Russia does not seem to be “blocking” the “solid outcomes” of recent BRICS climate negotiations, said Kate Logan, director of the China climate hub and climate diplomacy at the Asia Society Policy Institute (ASPI).
Will China and the BRICS emerge as climate leaders?
With the withdrawal of the US from the Paris Agreement under the Trump administration, there have been increasing calls for China to take up the mantle of climate leadership.
China, at least publicly, is eschewing these calls, but does seem to be open to agreeing to “demonstrate leadership” in tandem with others, as seen in an EU-China joint statement on climate change published in late July.
Many are watching for signs of whether China’s upcoming international climate pledge, which may be published next week, will contain ambitious targets that will encourage greater global ambition.
Beatriz Mattos, research coordinator at Brazil-based climate-research institute Plataforma CIPÓ, tells Carbon Brief that China’s position as a “major investor in the renewable energy sector” means there is “enormous potential” for both it and the BRICS to assume a climate leadership role.

$210 billion
The amount of foreign investment pledged by Chinese clean-energy technology manufacturers since 2022, according to a new report by the Net Zero Industrial Policy Lab covered by Bloomberg.
New science
Agricultural and Forest Meteorology
A new study examined the combined role of “forest activities and fire disturbance” (FAFD) on the effectiveness of China’s carbon sinks. It estimated that, between 1986 and 2020, the carbon emissions resulting from harvesting forests and forest fires offset around 54% of the carbon sequestration occurring through forestation. These findings, the authors said, “highlight the importance of accounting for carbon emissions from deforestation and forest fire when aiming to maximise carbon sequestration through forestation”.
Temperature extremes in early life and human capital: evidence from China’s labour market
Climatic Change
“Early-life exposure” to both extreme heat and extreme cold has “significant and persistent negative effects on adult labour income”, new research has found. The study, which draws from a dataset of more than one million individuals from China, said that, under a scenario with moderate warming (SSP2-4.5), average labour-income loss across China could total 0.77%, with the provinces of Qinghai, Henan, Fujian and Gansu most severely affected. It added that the impact of extreme heat on foetuses is “particularly pronounced”, with significant implications for future earnings.

China Briefing 18 September 2025: MEE on the move; AI and energy; BRICS and climate
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.”
