Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Record Europe heat
HOTTEST EVER: The UK broke its temperature record for June twice this week, while France recorded its hottest day ever two days in a row, reported the Guardian. The Times reported that temperatures reached 36.7C in Somerset on Thursday, as the “London Ambulance Service had its busiest-ever day for life-threatening emergencies”.
FRANCE FRYING: French newspaper Libération said that temperatures reached as high as 44.3C in the south-western commune of Pissos on Wednesday. Spain also recorded its highest daily average temperature for June, said BBC News. On Thursday, Switzerland also had its hottest June day, when temperatures reached 37C in four locations, reported SwissInfo.
CLIMATE LINK: CNN covered a rapid analysis from the World Weather Attribution service finding that fossil-fuelled climate change has made this heatwave the most severe and widespread in Europe’s history. Carbon Brief covered the broken heat records, explaining the influence of climate change.
‘Electrifying’ London talks
‘LONDON COOKING’: In a sweltering, packed-out event at London climate action week, UN chief António Guterres quipped that “London is not just calling, it’s cooking”, reported Edie. Guterres also used his address to release a “global call to action on methane” and to call on artificial intelligence companies to reveal their environmental impact and source their power solely from renewables by 2030, said the publication.
‘ELECTRIFY NOW’: Elsewhere, dozens of governments, led by the EU and the UK, committed to throwing “their political weight” behind a rapid electrification of the world’s economy, according to Climate Home News. A high-level summit in London’s Mansion House saw energy ministers and business leaders, joined by Guterres, in “calling for faster action to curb demand for oil, coal and gas by powering homes, industry and transport with clean electricity”.
FOSSIL TRANSITION: At the same event, ministers from Colombia and the Netherlands, the co-hosts of the world’s first summit on transitioning away from fossil fuels in April, unveiled a report on their key takeaways. It comes after the current Colombian government has been ousted by a presidential election defeat to a fossil-fuel-supporting Trump ally. Carbon Brief examined what this could mean for the world’s energy transition.
Around the world
- UK TARGET: The UK parliament has approved its “seventh carbon budget”, aimed at cutting emissions 87% below 1990 levels by 2040.
- TOTAL ACCOUNTABILITY: A French court has ordered oil-and-gas giant TotalEnergies to account for the emissions from the use of its products, following a case brought by a climate NGO, reported Le Monde.
- METHANE RULES: The US, Qatar and other major energy exporters have urged the EU to “rewrite planned methane emissions” rules for oil-and-gas imports, saying that the policy could disrupt fuel supplies to Europe, according to Reuters.
- CHINA MESSAGE: China’s special envoy for climate change, Liu Zhenmin, said at the World Economic Forum that energy shortages triggered by the Iran war should be a “lesson to countries to accelerate their energy transitions”, reported Bloomberg.
- US WEBSITE REVIVED: Former US government workers have “recreated a valuable climate-science website” shut down by the Trump administration last year, said the New York Times.
6,600 animals
The number of livestock that perished in transport during heat in England and Wales from June to August 2025, double the number killed the year before, reported Carbon Brief.

Captured
The UK government’s official climate advisers, the Climate Change Committee (CCC), has released its latest progress report, emphasising that faster electrification is the best way to secure lower energy bills and stronger energy security. Electrification has shot up the agenda in recent months, with the COP31 presidency calling for countries to back a global goal for 35% of “final” energy to come from electricity by 2035. The text of the CCC’s latest report uses the word “electrification” far more often than previous editions, as shown in the figure above.

Spotlight
Introducing ‘Project Cosmos’
Carbon Brief explains how it built a major new database of climate science research and unveils a new ranking of the 500 most highly cited publications, authors and institutions in climate science.
This week, Carbon Brief launched Project Cosmos – the world’s largest and most complete database of climate change research.
The database features more than 1.8m academic papers, books and reports, capturing the vast body of human knowledge about climate change that has accumulated over more than a century of academic study.
The climate science “universe” is based on reports from the Intergovernmental Panel on Climate Change (IPCC), which are recognised as the world’s most authoritative summaries of the latest climate science.
Since its first report was published in 1990, humanity’s knowledge about human-caused climate change has ballooned. The IPCC has published six sets of reports in total – each one longer than the last.
In total, IPCC reports reference more than 100,000 other papers, books and reports. This is the core of our climate science universe. Carbon Brief then built on this core, by looking at four other sources of data. Read more about how the Cosmos database was created here.

Every single publication in the Cosmos database is linked to at least one other through references. Visualising these links reveals a “galaxy” of references.
In the image above, each colour and cluster reveals different topics and densities of research. Explore the galaxy in an interactive map.
Cosmos 500
As part of an initial wave of preliminary analysis to demonstrate the scope of the Project Cosmos database, Carbon Brief has ranked the 500 most highly cited publications, authors and institutions in the database.
The most highly cited climate scientist is Prof Philippe Ciais, who has spent almost four decades researching the planet’s carbon cycle – and the ways in which humans have been impacting its balance. Carbon Brief recently interviewed Ciais in Paris.
The US tops the tables for the most highly cited authors and institutions. Almost half of the 500 most highly-cited authors are from US institutions. This raises particular concerns for the future of climate science, as US climate scientists and institutions are coming under attack under the Trump administration.
Experts from global south countries account for only 4% of all authors in the Cosmos 500. China stands out as the most highly-cited global south country. Meanwhile, only 10% of authors in the Cosmos 500 are women.
There are many possibilities for future avenues of research using the Cosmos database. Over time, the database could be used to reveal, for example, how interest in different areas of climate science has changed over time, plus identify potential knowledge gaps and, thus, opportunities for future research.
Carbon Brief invites researchers – including academics, journalists and analysts – to submit their own proposals for co-authored studies, literature reviews and analytical projects. Proposals should be sent to cosmos AT carbonbrief DOT org.

Q&A: What is in China’s new five-year plan for climate change?
China has released a five-year plan dedicated to addressing climate change.
The 15th five-year plan for a national response to climate change is the latest in a series to outline in-depth climate and energy targets for the 2026-2030 period.
These include five-year plans for “building a Beautiful China”, developing a “new-type energy system” and developing renewable energy.
There are also separate “action plans” for the 2026-2030 period, such as for peaking carbon emissions.
China has pledged to peak its emissions before 2030 and reach carbon neutrality before 2060.
The new plan does not include any major new targets, instead consolidating and reaffirming existing policies.
Nevertheless, it includes significant signals on key policy areas, such as non-carbon dioxide (CO2) greenhouse gases, global climate governance and carbon markets.
Below, Carbon Brief examines some of the notable elements in the latest five-year plan and what it reveals about China’s policy direction through to 2030.
What does the climate plan cover?
The Ministry of Ecology and Environment (MEE) released the plan in late July, in unison with 18 other government departments. These include the National Development and Reform Commission (NDRC), China’s top economic planning agency, and the National Energy Administration.
The document covers a range of topics, including CO2 emissions, other greenhouse gases (non-CO2 GHGs), carbon markets, carbon footprints, climate adaptation and international cooperation on climate change.
For the first time at the five-year plan level, the plan creates a comprehensive target system covering all areas of climate policy, say officials in a MEE Q&A.
They describe it as “the main policy instrument” for advancing China’s climate action during 2026-2030.
China rarely issues high-level multi-year policies dedicated to “responding to climate change”. In 2014, the NDRC published a plan on the topic running through to 2020, but this was not linked to a five-year plan period.
Qin Yan, principal analyst at ClearBlue Markets, tells Carbon Brief that the plan shows that China’s climate governance has reached “an unprecedented strategic level”.
She adds that the plan creates an “all-encompassing target system” to support China’s Paris Agreement climate pledges for 2030 and 2035.
In its 2030 pledge, China aimed to peak emissions “before 2030” and reduce carbon intensity – its emissions per unit of GDP – by more than 65% from 2005 levels.
Last year, president Xi Jinping personally announced China’s 2035 pledge to cut China’s greenhouse gas emissions to 7-10% below peak levels by 2035, while “striving to do better”.
The five-year plan marks a new phase in China’s climate policy, according to researchers at CIB Research, an economic research body affiliated with the Industrial Bank, whose largest shareholder is the Fujian provincial government.
Their analysis adds that the plan represents a broad effort to strengthen China’s climate-governance system, implementation mechanisms and underlying capacity.
Nevertheless, several headline targets and policies in the document simply reiterate already established plans.
These include:
- Cutting carbon intensity by 17% across the five years
- Reducing carbon intensity per product in industries under China’s carbon market by 3%
- Substituting fossil fuels with renewables
- Strengthening climate adaptation
- Supporting the “free flow” of cleantech
What does the plan say about non-CO2 GHGs?
The plan also goes into detail on China’s approach to non-CO2 GHGs. This includes reaffirming a target of an emissions “reduction capacity” from these gases totalling 30m tonnes of CO2 equivalent (MtCO2e) by 2030, although the baseline is unclear.
The target previously appeared in the overarching five-year plan, as well as the plan for building a “Beautiful China”.
The goal refers to emissions reductions, which can be realised through implementing current non-CO2 emissions reduction policies and projects, says Chen Meian, programme director and senior analyst at the Institute for Global Decarbonization Progress (iGDP).
She adds that it is “relatively achievable”, with sources including increasing the number of coal-mine methane utilisation projects.
She points to an MEE explanatory note for a draft methodology under the China Certified Emission Reduction (CCER) scheme, China’s voluntary carbon-credit market. Chen says the note suggests that projects using ventilation air methane and coal-mine methane with concentrations below 8% alone could deliver around 20MtCO2e of reduction by 2030.
The note states that, currently, such projects are estimated to be able to “generate annual emission reductions of approximately 4.5MtCO2e”.
In addition, Chen says, measures targeting industrial nitrous oxide (N2O) and hydrofluorocarbons (HFCs) could help make up the remainder needed to meet the target.
According to iGDP analysis of biennial reports submitted by China to the UNFCCC, China emitted around 14,000MtCO2e of GHGs in 2021, excluding land use, land-use change and forestry (LULUCF).
Non-CO2 GHGs accounted for around 2,700MtCO2e, or 19%, of the total, the majority of which was methane, as shown in the figure below.

China’s plans to curb these super-pollutants in the five-year period include coal-mine methane utilisation projects, end-of-pipe destruction technologies for HFCs and guidance on the use of catalysts to reduce N2O emissions.
The plan also calls for the recovery and replacement of sulphur hexafluoride (SF6) in power equipment.
For Chen, the plan’s focus on SF6 control is particularly noteworthy. She says the gas is “finally receiving policy attention” and that proactive action is “timely and will help avoid future emissions growth” as China’s power system expands.
What does the plan say about global climate governance?
One of the plan’s clearest objectives for international cooperation is for China to play a more active role in global climate governance.
By 2030, it says China should markedly increase its “influence, guiding power, shaping power and moral appeal” in this area.
It says China’s climate action could also feed into the Global Governance Initiative, a policy initiative aimed at reforming the global governance system.
China will also aim to “build a new narrative on climate governance”, it adds.
Prof Thomas Hale, a professor in public policy at the University of Oxford’s Blavatnik School of Government, writes on LinkedIn that the plan “marks a major rhetorical shift” towards China being increasingly willing to “lead and shape” global climate action.
Another clear focal point for international cooperation is in carbon markets.
The plan calls for China to expand the global influence of its carbon market, such as through international rule-setting, cooperation on standards and by hosting the China Carbon Market Conference.
Qin says China’s more active role in global carbon pricing is already evident in the launch of the open coalition on compliance carbon markets with the EU and Brazil. This coalition is expected to adopt a work plan at the China Carbon Market Conference in September.
Qin also notes that China “could become the world’s largest [carbon] offset buyer” as its energy transition progresses.
The country would, therefore, “benefit from helping shape global rules under the Article 6 framework [for carbon trading under the Paris Agreement]”, she adds.

Quarter of countries still missing UN climate plans 18 months after deadline
About a quarter of the countries signed up to the Paris Agreement are still breaching its rules by failing to submit a new national climate plan, 18 months after the February 2025 deadline.
Forty-five nations had not submitted a plan known as a nationally determined contribution (NDC), according to the Paris Agreement Implementation and Compliance Committee’s (PAICC) newly-published report of its 7-10 July 2026 meeting. One, Oman, has published it since the meeting.
Twelve countries ignored the committee’s repeated attempts to find out why they had not yet produced a climate plan, the report said. They will be invited to the committee’s next meeting, from September 1-4, so it can identify the challenges and constraints they face.
Members of the committee are divided, as they were at their last meeting, on whether to name those countries publicly and will debate the question again in September.
The PAICC does not have any power to punish governments, as building these powers into the Paris Agreement was thought to be so controversial that it could have stopped some governments from joining, experts have previously told Climate Home News.
A key requirement of the landmark 2015 Paris Agreement is that governments publish a more ambitious NDC every five years, setting targets to reduce their planet-heating emissions and outlining their policies to adapt to climate change, in order to meet the accord’s goals on limiting global warming and protecting people from its effects.
The latest set – the third round of plans, with new targets for 2035 – was due in 2025.
Some medium-sized emitters
Countries without an updated NDC include Egypt, Vietnam, Argentina and the Phillippines, all of which rank among the world’s 40 largest greenhouse gas emitters. The rest of the countries are smaller, poorer nations, with many in Africa or the Caribbean.
Some nations have argued that they cannot put together an NDC – which requires a significant amount of work in tracking emissions and consulting on how to curb them across the economy – because of exceptional circumstances. For example, a letter from a Sudanese official to the PAICC committee, seen by Climate Home News, says that the country’s civil war has led to the suspension of its NDC preparation.
The US and Iran are not signed up to the Paris Agreement, although the US submitted a 2035 NDC under the Biden administration before Donald Trump pulled the US out of the UN climate accords.
The committee also expressed concern that the UN’s NDC registry continued to label the climate plans of countries that are no longer party to the Paris Agreement as “active”, according to its report. The US submission has since been archived.
Since the last PAICC meeting in March, ten countries have published NDCs. The committee did not name them but they include India, Algeria, Cameroon and Guyana.

China’s coal power rebounds as record clean energy goes to waste
China’s use of coal for electricity grew in the first half of 2026 as a record amount of wind and solar power was wasted through curtailment, new research has found.
The world’s largest greenhouse gas emitter brought 30 gigawatts (GW) of new coal power capacity into operation in the six months to June and coal-fired generation rose 3% after falling last year, according to a report by the Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor (GEM). Only 2.7GW of coal power was retired in the same period.
The coal expansion stems from a surge in power plant approvals that followed power shortages caused primarily by high coal prices in 2021, when blackouts and factory shutdowns hit roughly 20 Chinese provinces. Local governments responded by fast-tracking new coal projects as insurance against future outages.
A further 274 GW of coal capacity – equivalent to roughly a fifth of China’s existing coal fleet – is already either under construction or has permits to be built, meaning much of the sector’s expansion is locked in for years, the report says.
“Climate concern”
Qi Qin, the report’s author, said the coal lock-in is a “climate concern”. “After coal power plants are built, they will seek revenue and operating hours for decades and that can crowd out clean power and slow the retirement of the older coal power units,” she added.
The coal buildout is happening at the same time as Beijing signals a gradual shift in its energy rhetoric. In a document published last April, the Chinese government called for the country to “reasonably control” both China’s capacity to generate electricity from coal and, for the first time, how much electricity it actually generates from coal.
China has also pledged in its latest five-year plan to cut carbon emissions per unit of gross domestic product – known as carbon intensity – by 17% between 2026 and 2030. It plans to reach net zero by 2060.
But, according to Qi, there is still a real gap between the direction of national policy and what is happening on the ground.
Growing renewables curtailments
While China generated less than half of its electricity from coal for the first time in the six months to last June, growing demand for electricity meant coal power generation still rose 3.4%, reversing a roughly 1% decline recorded in 2025, the report said.
Available clean electricity from solar and wind, which have seen a record expansion in China, would have been more than enough to meet the extra demand and drive coal power down if it had been fully used, the report said. Instead, the amount of clean electricity wasted kept growing.
Estimated rates of curtailment, the intentional reduction of electricity from a source, for wind and solar were up by about a half in the six-month period compared to last year, wasting the equivalent of Indonesia’s annual electricity output.


Coal’s protected status
Researchers said that was caused by the Chinese grid’s inability to absorb the additional clean electricity, in addition to energy contracts and pricing mechanisms skewed in favour of coal power.
Chinese coal generators are required to sign long-term contracts covering a fixed share of the previous year’s output, now standing at 70%. Qi said that, out of fear of electricity shortages, regulators introduced these arrangements to protect coal power plants by guaranteeing them predictable prices and utilisation rates.
Additionally, China has also begun paying coal plants to stand ready to generate electricity, rather than for actually running, through new capacity payments introduced this year.
China unveils underwhelming emissions-cutting target for 2035
Qi said that, while each of these mechanisms has a legitimate purpose on its own, they now combine to give coal power excessive protections. “When renewables are abundant, they [coal operators] don’t have the incentive and are not required to ramp down,” she added.
The report suggested lowering, or even suspending, coal-specific contract minimums in provinces that are experiencing clean energy being wasted or prolonged periods of zero or negative electricity prices. That would help coal transition to a more flexible backup role and facilitate the integration of renewables, the researchers argued.
They also urged the Chinese authorities to halt permits for new coal power projects and reassess those that have already been permitted, while favouring grid expansion, energy trade across provinces and storage as ways to boost energy reliability.
