Key developments
Floods killed 60 people after ‘year of rain in a week’
HUMAN TOLL: Heavy rainfall in late July killed at least 60 people across northern China, with flooding and landslides affecting Beijing and neighbouring Hebei province, Reuters reported, adding that “meteorologists link an increase in extreme weather…to climate change”. In some areas, a “year’s worth of rain fell in less than a week”, another Reuters article said. China’s “usually arid north has seen record rains in recent years”, but Beijing’s topography “amplif[ied] the deluge” that killed more than 30 people in the capital, the newswire added. Other affected regions included Shanxi, Shaanxi, Liaoning, Shandong, Tianjin and Inner Mongolia, according to various news outlets.
PERSISTENT HEAT: Five people were killed in southern Guangdong province due to “torrential rain”, said the state-run newspaper China Daily. Shanghai evacuated “around 280,000 people” as storm Co-may brought “strong winds and heavy rainfall”, Bloomberg said. Elsewhere, China Daily reported on “persistent high temperatures” in central China, adding that multiple regions faced intense heat or rainfall this week. The southern city of Chongqing “elevated its heatwave warning to the highest level” following temperatures “exceeding 40C for a week”, Reuters said.
RELIEF FUNDS: State broadcaster CGTN said China allocated more than one billion yuan ($139m) to areas across China for flood and drought relief efforts. Beijing and its neighbouring provinces received 550m yuan ($77m) for flood relief, reported the Hong Kong-based South China Morning Post (SCMP).
NEW OUTBREAK: Meanwhile, thousands of residents in southern China’s Guangdong province have contracted chikungunya, a mosquito-borne disease, Bloomberg reported, quoting an expert saying the “surge in chikungunya cases is likely due to favorable climatic conditions”. The outbreak “is the latest sign that tropical diseases…are expanding their reach, as climate change lets mosquitoes live in new territories”, it added.
Government tackled ‘Industrial Cthulhu’
OVERCAPACITY POLICIES: Regulators released a “draft amendment” to China’s pricing law that aims to “rein in price wars”, Reuters said. China will “name and shame” companies that continue to implement “ruinous competition”, said Bloomberg. Draft “guidance” was also issued on deploying government funds, SCMP reported, to prevent continued “overconcentrat[ion]” of local government investment in the “new three” and other sectors. China’s leadership also called for “reducing excess competition” and regulating “local government practices in attracting investment”, said Xinhua. According to Bloomberg, this showed “China’s leaders see the dangers” of China’s manufacturing strength “clearly”. (It added that some netizens had nicknamed the sector “Industrial Cthulhu”, in a “tongue-in-cheek” comparison that it said was meant to imply that “China’s manufacturing power is a beast”.)
SUPERCHARGING DEMAND: Domestic sales of new-energy vehicles (NEVs) between January and June 2025 rose 40% year-on-year to just under seven million units – 44% of total car sales – reported the Communist party-affiliated People’s Daily, while exports “surged” by 75%. Energy news outlet International Energy Net quoted a National Energy Administration (NEA) official saying China expects 2025 power demand for EV charging alone to equal the “annual power generation of the Three Gorges dam”.
HIDDEN FIGURES: While the figures show that 2025 is “shaping up to be another stellar year” for China’s EV industry “on paper”, Caixin said, “overcapacity” and fierce price wars mean the industry’s mood is “far from celebratory”. Separately, Reuters found it is “increasingly common” for automakers in China, including EV manufacturers and foreign brands, to “inflate car sales”.
EV TARIFFS: Meanwhile, Chinese EVs exports to the EU have made a “full comeback from tariffs set in place last year”, with Chinese automakers’ share in Europe’s EV market surpassing 10%, according to Bloomberg. Elsewhere, Thailand has “adjusted” EV subsidies to encourage exports as surging Chinese investment creates excess domestic “capacity”, said finance news outlet Caixin. EV manufacturer BYD has been offered a “short-term tariff break” in Brazil, but will face aggressive “hikes…in the long run”, SCMP reported.
Forecast for solar growth in 2025 rose to 300GW
GENERATION SHARE: Renewable energy accounted for “almost 40% of total power generation” in the first half of 2025, NEA officials said at a press conference covered by BJX News. New solar and wind generation also covered “total growth in electricity demand”, the energy news outlet added. BJX News also added that, according to the NEA officials, non-fossil fuel sources now account for 60% of China’s electricity mix. Meanwhile, the China Photovoltaic Industry Association “raised its forecast for new domestic solar installations this year” to 270-300 gigawatts (GW), citing the “minimal impact” of “new policies such as document 136” on large-scale clean-energy bases, reported business news outlet Jiemian. China had already installed 212GW of new solar capacity in the first half of the year, said China Daily.

INDUSTRY INSPECTIONS: The government will conduct “energy conservation inspections” on polysilicon manufacturers, Jiemian said. It quoted an anonymous “industry insider” as saying the targeted companies are “not all…polysilicon projects for photovoltaic use”, adding that the inspections likely aim to identify “projects that consume resources without creating actual value”. Meanwhile, Reuters found “China’s biggest solar firms shed nearly one-third of their workforces last year”, illustrating the “pain from the vicious price wars”, while “more than 40 solar firms have delisted, gone bankrupt or been acquired” since 2024.
‘ORDERLY’ DEVELOPMENT: China issued a new policy on “further regulating the use of farmland for solar projects”, calling for better management and strict supervision of “solar projects involving the use of farmland”, reported International Energy Net. The NEA also pledged to “guide the orderly development of distributed [solar] projects and ensure safe and efficient consumption”, said another International Energy Net article.
Central bank boosted finance for ‘future energy’
NEW ENERGY FINANCE: China’s central bank, alongside several government ministries, released guidance on financing “new industrialisation”, BJX News reported, adding that it encouraged supporting sectors such as “new energy” in “raising capital” and encouraged state-run investment funds to focus on “future energy” and other “future industries”. The guidance also called for more support for “green and low-carbon transformation” and clean-energy technologies. Separately, China will evaluate the energy consumption and potential carbon emissions of “fixed asset” investments over a certain threshold of energy or coal consumption, said International Energy Net.
‘CLIMATE THREATS’: The CMA launched a new “initiative” to “establish a global early warning service network in the face of escalating climate threats”, CGTN said. China also issued a plan to “create greener, safer and more livable environments” in the face of “intensifying global climate change”, said People’s Daily. China’s agriculture ministry also released a work plan to “ensure a bountiful autumn grain harvest” in the face of an “above-average number of extreme weather and climate events this year”, Xinhua reported.
NDRC ON HIGH DEMAND: The National Development and Reform Commission (NDRC), China’s top economic planning agency, commented on recent high power demand, reported International Energy Net. It explained that the NDRC said China will “ensure an adequate and stable [power] supply” through effective management of coal production and will “integrate new energy’s supporting role” with coal’s role as a “bottom-line guarantee” (兜底保障) for power generation. Separately, the NDRC also highlighted “promoting…comprehensive transformation under dual-control of carbon mechanisms” as one of its “key tasks” for the rest of 2025, according to China Energy Net.
Spotlight
Guest spotlight: What an ‘ambitious’ 2035 electricity target looks like for China
A new study has found that China must at least double its wind and solar capacity by 2035 to align its power sector with a 2C global warming target.
In this issue, co-authors Zhenhua Zhang and Michael R Davidson, a PhD student and associate professor at the University of California, San Diego, respectively, explain how China could encourage climate ambition by setting power-sector targets.
The full article is available on Carbon Brief’s website.
China’s power sector is both the world’s largest emitter and the largest source of clean-energy growth.
This means it will be a key part of China’s next nationally determined contribution (NDC) – its climate pledge under the Paris Agreement for 2035.
In our new study, co-authored with experts from Tsinghua University, we model pathways for China’s power system up to 2035 that are consistent with its wider climate goals.
China has already surpassed its 2030 renewable deployment target, due to recent record-breaking annual additions.
However, new coal-power developments and rapid growth in electricity demand pose a threat to meeting China’s other targets.
Our research looks at the rate of growth from clean energy that would be required to not only meet China’s rapidly rising demand for electricity, but also to push down its coal generation and squeeze emissions from the power sector.
Staying below 2C
We simulate a range of scenarios for 2035, based around two different scenarios for China that are compatible with a global limit of 2C warming this century.
The basic 2C trajectory would see China’s power-sector emissions fall to 36% below 2024 levels by 2035, whereas the more ambitious 2C trajectory has a 42% decline.
It shows wind and solar energy would need to supply around 40% of China’s electricity by 2030, if the country aims to remain on track for 2C of global warming.
Solar and wind power generation would need to then rise to 50% by 2035, up from 17.9% in 2024.
This growth would substantially reduce the system’s reliance on coal and other fossil fuels, which would decrease to 35% of generation in 2030 and 25% in 2035.
The more ambitious scenario, which targets limiting global warming since the pre-industrial period to 1.5-2C, would see even higher wind and solar generation shares of 44% by 2030 and 54% by 2035.
Under the different scenarios, China’s wind and solar capacity would rise from around 1,700GW today to 2,350-2,780GW by 2030 and 2,910-3,800GW by 2030, requiring annual additions of 120-220GW.
Recent wind and solar additions have already exceeded this pace.
Challenges with grid integration and supporting infrastructure could slow future large-scale buildouts, meaning battery and grid capacity would need to rise by 6% and 5% per year to 2035, respectively to better integrate renewables into the grid.
The NDC and beyond
Due to the rapidly evolving economic and geopolitical situation, there are good reasons to expect that China’s topline emissions number in its NDC may be underwhelming. But there is an opportunity to emphasise and expand ambition within the power sector through additional sectoral targets.
While China has previously set a target for the absolute capacity of wind and solar, a goal for the share of electricity generation would set a narrower range for future power sector emissions.
Given current uncertainties around the pace of power demand growth, for example, a target for clean energy share might provide greater confidence than a capacity target alone.
Regardless of what targets are set, achieving the growth of clean energy modelled in our study would support China’s long-term climate commitments and demonstrate the nation’s intent to be a clean-energy powerhouse.

1.35 billion
In tonnes per annum, the amount of coal-mine capacity that is “at various stages of development” in China, according to updated data from thinktank Global Energy Monitor – more capacity than “all other countries combined”.
New science
Communications Earth & Environment
A new study found a “significant increase” in both dry-hot and wet-hot extremes in China during the May-September warm season. The authors investigated changes in hot extremes in 136 Chinese cities over 1981-2022. They found that wet-hot extremes accounted for 36% of all hot days, while dry-hot days accounted for only 4%. The authors said their findings “underscore the urgent need for adaptive urban strategies to mitigate the growing risk of compound temperature-humidity extremes under ongoing urbanisation and climate change”.
China’s nationwide streamflow decline driven by landscape changes and human interventions
Science Advances
The amount of water running through rivers, or “streamflow”, has declined at more than 70% of Chinese hydrological stations over the past six decades, according to a new study. The authors combined data from more than 1,000 hydrological stations with climate models to produce a “comprehensive national assessment” of streamflow across China. They found that decreases in streamflow were mainly in northern China and were driven by changes in land use, but that increases in streamflow were found in the south, mainly driven by “climate change and variability”.

China Briefing 7 August 2025: Deadly floods; ‘Industrial Cthulhu’; Higher solar forecast
Dr. Stacy Jupiter is the Executive Director of the Wildlife Conservation Society’s Global Marine Program. Melissa Wright is Bloomberg Ocean Initiative Lead at Bloomberg Philanthropies.
For years, the dominant story on coral reefs has been one of inevitable loss, with news headlines focusing on mass bleaching, ecosystem collapse, and catastrophic tipping points. As ocean temperatures continue to rise, many people have come to see the decline of the world’s reefs as unavoidable.
The threats are real and urgent, but new evidence points to a more complicated and useful conclusion: some reefs still have a meaningful chance to survive and recover, provided they are protected.
A major new analysis, published today with the support of Bloomberg Philanthropies, identifies more than 165,000 square kilometers of coral reefs, across 71 countries and 100 territories and jurisdictions, with the strongest potential to withstand and recover from climate impacts.
Drawing on more than 45,000 coral surveys, along with decades of climate and ocean data, the research finds that three times more reefs may be capable of surviving the climate crisis than previously understood. That has major implications for reef-dependent communities, food security, coastal protection, fisheries, tourism, and national economies.

Essential natural infrastructure for communities
The findings make clear that reefs will not all respond to climate impacts in the same way. Some are located in rare underwater cool spots that can help shield them from extreme heat. Some show greater resistance to bleaching and other climate-related stress. Others recover more quickly after severe disturbances. These differences matter because they show where protection can have the greatest long-term impact.
More than 500 million people depend on reefs for food, livelihoods, and coastal protection. For those communities, climate-resilient reefs are not an abstract conservation priority. They are essential natural infrastructure. They help protect coastlines, sustain fisheries, support local economies, and reduce climate risk. Because ocean currents move coral larvae and marine life between reef systems, some of these reefs may also help regenerate wider reef ecosystems after climate shocks.
This should change how governments, funders, and conservation partners prioritize action.
Climate change remains the greatest long-term threat to coral reefs. At the same time, many of the pressures pushing reefs closer to collapse are immediate and local. Sewage pollution, deforestation, agricultural runoff, destructive fishing practices, and poorly managed coastal development continue to damage reefs that are already under stress. Recent research shows that water pollution and fishing pressure are now among the leading local threats affecting nearly two-thirds of the world’s coral reefs.
These pressures can be reduced. Governments and local partners are already working to improve reef management, cut pollution, strengthen enforcement, and protect critical ecosystems. Those efforts need to move faster, alongside much stronger action to reduce greenhouse gas emissions.
Prioritising climate-resilient reefs
The new maps of climate-resilient reefs give governments, communities, and reef managers a clearer basis for action. They show where reefs have the strongest potential to persist over time, and where protection can deliver the greatest benefits for people, coastlines, and economies.
Right now, only around 28 percent of the identified climate-resilient reefs fall within protected or conserved areas. If these reefs are among the most capable of surviving climate impacts and helping regenerate broader reef systems, they should be prioritized for protection, management, and investment.
The case for action is practical as well as ecological. Healthy reefs can reduce wave energy by up to 97 percent, helping protect coastlines from storms, flooding, and erosion. They support fisheries that feed millions of people, sustain tourism jobs and local economies, and help reduce climate risk for vulnerable coastal communities.
For many families, a healthy reef means food, income, and protection when storms hit. For Indigenous Peoples and coastal communities, reefs are also tied to culture, heritage, identity, and traditional knowledge systems.
Ocean conservation must catch up
Governments are beginning to recognize the urgency of protecting climate-resilient reefs. At last year’s UN Ocean Conference in Nice, 11 countries signed a declaration committing to stronger protection of these reefs, including action to address destructive fishing, pollution, and unsustainable coastal development.
As leaders meet in Kenya this week to discuss the challenges facing the world’s ocean, more governments should join the declaration and help build a broader coalition committed to safeguarding these critical ecosystems.
As coral reefs pass tipping point, ocean protection rises up political agenda
Some countries are already showing what this leadership can look like. Brazil has included corals in its national climate plans. The Bahamas is embedding reef protection into national policy and local stewardship systems. The declaration offers a way to build on these efforts and scale them globally.
But commitments will not be enough. Success will depend on implementation. That means stronger protection and management, reduced local pressures, increased investment, and meaningful support for the Indigenous Peoples and local communities stewarding these ecosystems.
The science is clear. Many reefs still have the capacity to persist and recover. The question is whether policy and investment will move quickly enough to protect them, so they can continue sustaining communities, economies, and coastlines for generations to come.

Months After a Jet Fuel Leak, No Agency Tested Waters Downstream of Piscataway Creek. So Community Groups Are Doing It Themselves.
Authorities that manage the Potomac River tributary did not sample the stretch where residents fish and recreate. One Indigenous leader sees the lack of response as part of a pattern of ongoing neglect.
In the five months after jet fuel started leaking from Joint Base Andrews into Piscataway Creek, no agency tested the water or sediment some 20 miles downstream, where the creek empties into the Potomac River and the shoreline community and anglers gather to fish and boat along the riverbank.

Trump Administration Abandons Fight Against Wind Energy as Clean Energy Output Surges
The clean energy sector is showing resilience despite challenges thrown at it by a hostile White House, a recent report found. A string of legal victories has further dampened the Trump administration’s efforts to halt wind and solar power.
The Trump administration has abandoned its effort to halt wind energy projects across the United States and dropped its challenge to the court ruling that tossed President Donald Trump’s order freezing federal permitting and leasing for wind projects. States that challenged the order hailed the development as one of the most significant legal victories against the Trump White House’s campaign against the energy transition.
