Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
‘Historic’ court victory
FIRST-EVER RULING: The European Court of Human Rights this week ruled that insufficient action to tackle climate change is a violation of human rights, DeSmog reported. In a “historic” judgement, the court ruled that Switzerland’s inadequate action on cutting emissions breached the rights to respect for family and private life of some of its most vulnerable citizens, DeSmog said. The case was brought by a group of 2,000 older Swiss women, BBC News reported.
PORTUGUESE CASE: The same court also dismissed a climate case brought by six Portuguese young people, finding the group had not exhausted legal action through the national courts, the Financial Times reported. Gerry Liston, the lawyer for the Portuguese youths, said that, despite the judges dismissing the case, the court’s ruling on the Swiss women’s action was “a massive win for all generations”, added the outlet.
INDIAN COURT: Also this week, India’s Supreme Court expanded the “right to life” to include “protection against adverse effects of climate change”, adding that “climate change threatens ‘constitutional guarantees of equality and health’, impacting factors such as air pollution, disease, and food security”, the Independent reported. An editorial in the Indian Express described the decision as a “call to action”, adding that the significance of the ruling “cannot be overstated”.
Heat goes on
ROASTING MARCH: March 2024 was the “tenth straight month to be the hottest on record”, reported the Associated Press. March temperatures averaged at 14.14C – 1.68C warmer than in the late 1800s, when the fossil fuel era began, according to AP. It added that “climate scientists attribute most of the record heat to human-caused climate change from carbon dioxide (CO2) and methane emissions produced by the burning of coal, oil and natural gas”.
HEAT-TRAPPING GASES: Atmospheric levels of the three most important heat-trapping gases – CO2, methane and nitrous oxide – reached record highs again last year, the Guardian reported. The global concentration of CO2 rose to an average of 419 parts per million (ppm) in 2023, while methane rose to an average of 1,922 parts per billion (ppb) and nitrous oxide climbed slightly to 336ppb, the outlet said.
‘RAISE VOICES’: Amid the records, UN climate chief Simon Stiell urged “ordinary people everywhere” to “raise their voices” over climate change in a speech in London, the Financial Times reported. Stiell warned that humanity has just two years left to “save the world”, adding “we still have a chance… but we need these stronger [national climate] plans, now”, reported the Associated Press.
Around the world
- EU INVESTIGATION: The EU launched an investigation to examine “whether Chinese companies participating in wind parks across Europe may have benefited from state support from Beijing”, said the Financial Times.
- BIGGEST ICEBERG: BBC News tracked the world’s biggest iceberg – more than twice the size of Greater London – which has “begun to drift at pace once more” after a “few weeks loitering on the fringes of Antarctica”.
- BIGGEST ECONOMIES: G20 countries and “the multilateral development banks they fund” put £112bn into overseas fossil fuel development over 2020-2022, the Guardian reported. Despite pledging in 2022 to halt such financing, oil and gas funding “has continued at a strong pace”, the outlet added.
- UK POLITICS: Politico reported that the UK’s rightwing populist party Reform, the brainchild of Brexiteer Nigel Farage, has plans to make scrapping climate policies a central part of its campaigning in the next general election.
- SEVERE FLOODING: Russia and Kazakhstan have ordered more than 100,000 people to evacuate after melting snow swelled rivers beyond bursting point, leading to the worst flooding in the area for at least 70 years, reported Reuters.
- CHINA COAL: China accounted for 95% of the world’s new coal power construction activity in 2023, according to the latest annual report from Global Energy Monitor covered by Carbon Brief.

The total length of “ghost roads” uncovered by researchers studying deforestation in the Asian Pacific, according to Carbon Brief.
Latest climate research
- A new study in Nature Climate Change warned that meteorites holding potential clues to life’s origins or the prospect of alien existence are fast disappearing from Antarctica because of climate change.
- Geoengineering methods that change the planet’s radiative forcing – aiming to reduce the amount of energy that reaches the surface of the Earth – could increase the incidence of fires in the Arctic, when combined with very high greenhouse gas emissions, new research in Communications Earth & Environment suggested.
- A new study in npj Climate Action found that “Roman Catholics are less likely to believe in man-made climate change as compared to evangelical Christians”. However, the more positive a respondent’s view of Pope Francis, the more likely they are “to acknowledge the effect of human activity on global warming”, it said.

Captured
Carbon Brief has just published a two-part miniseries on the complex topic of climate migration. Carbon Brief’s explainer looked into the main drivers of why people move. Using data from the Internal Displacement Monitoring Centre (IDMC), Carbon Brief analysis showed that most climate-linked internal displacement is due to floods and storms (see above). The series also includes a special report on climate-driven migration in rural Thailand. Carbon Brief’s science journalist Ayesha Tandon also produced a video on her investigation into climate-driven migration in Thailand.
Spotlight
K-pop fans campaign for climate change
This week, Carbon Brief speaks to K-pop fans about their efforts to tackle climate change.
Dayeon Lee is a Tokyo-based South Korean student, and before discovering and joining climate campaigns, she was a “guilty” K-pop fan.
“K-pop” is a term for popular music from South Korea. K-pop has witnessed an explosion in popularity since the term first appeared internationally in the 2000s.
“I think people have the stereotype of K-pop fans, thinking we are just a group of crazy girls being obsessed with boys, but we are more than that, we are also a group of young people who care about the planet,” Lee told Carbon Brief.
“Korean entertainment companies produce a lot of album covers and we as fans buy hundreds of albums to support our idols. The companies don’t care about the environmental cost and waste, but we bear the guilt.”
Looking to make a change, Lee joined the campaign group Kpop4planet in 2021. The group, which is managed by K-pop fans, launched the campaign “No K-pop on a Dead Planet”, urging the industry to “make K-pop sustainable” and produce more eco-friendly albums.
“We had K-pop fans returning hundreds of albums to the major entertainment companies in South Korea to make sure they are aware of the issue. Although they didn’t officially respond to us, they started to introduce digital albums with purchasing code fans can scan,” said Lee.
The online campaign has in total attracted more than 100,000 people to join and they hope to inspire more.
There are an estimated 178m active K-pop fans worldwide. Kpop4planet’s campaigns cover a wide range of environmental issues, from reducing the high cost of fashion worn by K-pop singers, to protecting a beach featuring in K-pop songs and zero-emissions concerts.
“Since K-pop stars are involved with so many industries…that need to become more sustainable, we want to motivate and gather the power and influence of K-pop fans and the youth… to change the companies that are heavily polluting the environment by using fossil fuels,” said Lee.
Lee told Carbon Brief that K-pop entertainment agencies have already listened to their concerns, with some of them, such as South Korean record label JYP, committing to use 100% renewable electricity to power its operation.
‘Drop coal’
Recently, Kpop4planet decided to target the Korean motor company, Hyundai, which had signed a deal with an Indonesian company to source aluminium from a coal-powered smelter in North Kalimantan, Indonesia.
“Hyundai has a good image in Indonesia because they use the image of Korean band BTS as ‘their face’,” said Lee, adding that Kpop4planet hopes to leverage their K-pop fan stance to convince the company to “drop coal”.
Another campaigner Nural Sarifah, based in Indonesia, told Carbon Brief that the group has undertaken a “series of activities” to campaign against Hyundai’s decision, including delivering a signed petition “with a touch of K-pop dance” outside the Hyundai Motor Studio in Jakarta.
On 2 April, Reuters reported that Hyundai and its Indonesian supplier had “ended an aluminium supply agreement after calls by a climate campaigner backed by K-pop fans not to procure supplies of the metal produced using coal power”.
Hyundai announced in a statement that it had “decided to explore other opportunities independently” in Indonesia, according to the news agency. Lee told Carbon Brief:
“This move is a victory for thousands of K-pop fans who took action. We are glad that Hyundai is now exploring options to acquire transparent and sustainable sourcing materials in Indonesia.”
Lee added that their campaign will not stop there:
“Ultimately, we would like to use our collective power to [make] change. We want to secure the future that K-pop fans and the youth will inherit.”

It’s been less than 20 years since baby food in plastic pouches first appeared on supermarket shelves. Since then, these convenient and popular “squeeze-and-suck” products have become the dominant packaging for baby food, transforming the way that millions of babies are fed around the world. But emerging evidence raises concerns that big food brands are feeding our children plastic pollution with unknown consequences, by selling baby food in flexible plastic packaging.
Testing commissioned by Greenpeace International in 2025 found plastic particles in the baby food products of two global consumer goods companies – Danone and Nestlé. The study suggests a link between the type of plastic the pouches are lined with – polyethylene – and some of the microplastics found. Tests also suggest a range of plastic-associated chemicals in the packaging and food of both products.

U.N. General Assembly Embraces Court Opinion That Says Nations Have a Legal Obligation to Take Climate Action
The U.S. was among eight countries that voted against endorsing the nonbinding ruling that said all nations must take steps to limit temperature rise to 1.5 degrees Celsius.
The United Nations General Assembly on Wednesday voted overwhelmingly in favor of a climate justice resolution championed by the small Pacific Island nation of Vanuatu. The resolution welcomes the historic advisory opinion on climate change issued by the International Court of Justice in July 2025 and calls upon U.N. member states to act upon the court’s unanimous guidance, which clarified that addressing the climate crisis is not optional but rather is a legal duty under multiple sources of international law.
The number of new coal-fired power plants built around the world hit a “10-year high” in 2025, even as the global coal fleet generated less electricity, amid a “widening disconnect” in the sector.
That is according to the latest annual report from Global Energy Monitor (GEM), which finds that the world added nearly 100 gigawatts (GW) of new coal-power capacity in 2025, the equivalent of roughly 100 large coal plants.
It adds that 95% of the new coal plants were built in India and China.
Yet GEM says that the amount of electricity generated with coal fell by 0.6% in 2025 – with sharp drops in both China and India – as the fuel was displaced by record wind and solar output, among other factors.
The report notes that there have been previous dips in output from coal power and there could still be ups – as well as downs – in the near term.
For example, nearly 70% of the coal-fired units scheduled to retire globally in 2025 did not do so, due to postponements triggered by the 2022 energy crisis and policy shifts in the US.
However, GEM says that the underlying dynamics for coal power have now fundamentally shifted, as the cost of renewables has fallen and low usage hits coal profitability.
China and India dominate growth
In 2025, coal-capacity growth hit a 10-year high, with 97 gigawatts (GW) of new power plants being added, according to GEM.
(Capacity refers to the potential maximum power output, as measured in GW, whereas generation refers to power actually generated by the assets over a period of time, measured in gigawatt hours, GWh.)
This is the highest level since 2015 when 107GW began operating, as shown in the chart below. This makes 2025 the second-highest level of additions on record.
The majority of this growth came from China and India, which added 78GW and 10GW, respectively, against 9GW from all other countries.
Yet GEM points out that, even as coal capacity in China grew by 6%, the output from coal-fired power plants actually fell 1.2%. This means that each power plant would have been running less often, eroding its profitability. Similarly, capacity in India grew by 3.8%, while generation fell by 2.9%.
China and India had accounted for 87% of new coal-power capacity that came into operation in the first half of 2025. The shift up to 95% in the year as a whole highlights how increasingly just those two countries dominate the sector, GEM says.
Christine Shearer, project manager of GEM’s global coal plant tracker, said in a statement:
“In 2025, the world built more coal and used it less. Development has grown more concentrated, too – 95% of coal plant construction is now in China and India, and even they are building solar and wind fast enough to displace it.”
Both China and India saw solar and wind meet most or all of the growth in electricity demand last year.
Analysis for Carbon Brief last year showed that, in the first six months of 2025 alone, a record 212GW of solar was added in China, helping to make it the nation’s single-largest source of clean-power generation, for example.
However, the country continues to propose new coal plants. In 2025, a record 162GW of capacity was newly proposed for development or reactivated, according to GEM. This brought the overall capacity under development in the country to more than 500GW.
China’s 15th “five-year plan”, covering 2026-2030, had pledged to “promote the peaking” of coal use, while a more recent pair of policies introduced stricter controls on local governments’ coal use.
For its part, in India some 28GW of new coal capacity was newly proposed or reactivated last year, bringing the total under development to 107.3GW and under-construction capacity to 23.5GW.
The Indian government is planning to complete 85GW of new coal capacity in the next seven years, even as clean-energy expansion reaches levels that could cover all of the growth in electricity demand.
Outside of China and India, GEM says that just 32 countries have new coal plants under construction or under development, down from 38 in 2024.
Countries that have dropped plans for new coal in 2025 include South Korea, Brazil and Honduras, it says. GEM notes that the latter two mean that Latin America is now free from any new coal-power proposals.
This means that both electricity generation from coal and the construction of new coal-fired power plants are increasingly concentrated in just a few countries, as the chart below shows.
Indonesia’s coal fleet grew by 7% in 2025 to 61GW, with a quarter of the new capacity tied to nickel and aluminium processing, according to GEM.
Turkey – which is gearing up to host the COP31 international climate summit in November – has just one coal-plant proposal remaining, down from 70 in 2015.
The amount of new coal capacity that started to operate in south-east Asia fell for the third year in a row in 2025, according to GEM.
Countries in south Asia that rely on imported energy are increasingly looking to other technologies to protect themselves from fossil-fuel shocks, such as Pakistan, which is rapidly deploying solar, states the GEM report.
In Africa, plans for new coal capacity are concentrated in Zimbabwe and Zambia, the report shows, with the two countries accounting for two-thirds of planned development in the region.
‘Persistence of policies’
While new coal plants are still being built and even more are under development, GEM notes that the global electricity system is undergoing rapid changes.
Crucially, the growth of cheap renewable energy means that new coal plants do not automatically translate into higher electricity generation from coal.
Without rising output from coal power, building new plants simply results in the coal fleet running less often, further eroding its economics relative to wind and solar power.
Indeed, GEM notes that electricity generation from coal fell globally in 2025. Moreover, a recent report by thinktank Ember found that renewable energy overtook coal in 2025 to become the world’s largest source of electricity.
GEM notes that coal generation may fluctuate in the near term, in particular due to potential increases in demand driven by higher gas prices.
It adds that gas price shocks, such as the one triggered by the Iran war, can cause temporary reversals in the longer-term shift away from coal.
According to Carbon Brief analysis, at least eight countries announced plans to either increase their coal use or review plans to transition away from coal in the first month of the Iran war. However, a much-discussed “return to coal” is expected to be limited.
GEM’s report highlights that global fossil-fuel shocks can have an impact on the phase out of coal capacity over several years.
In the EU, for example, 69% of planned retirements did not take place in 2025, due to postponements that began in the 2022-23 energy crisis triggered by the Russian invasion of Ukraine, according to the report. Countries across the bloc chose to retain their coal capacity amid gas supply disruptions and concerns about energy security.
Yet coal-fired power generation in the bloc is now more than 40% below 2022 levels. Again, this highlights that coal capacity does not necessarily translate into electricity generation from coal, with its associated CO2 emissions.
Overall, GEM notes that “repeated exposure to fossil-fuel price volatility is as likely to accelerate the shift toward clean energy as it is to delay it”.
GEM’s Shearer says in a statement:
“The central challenge heading into 2026 is not the availability of alternatives, but the persistence of policies that treat coal as necessary even as power systems move increasingly beyond it.”
In the US, 59% of planned retirements in 2025 did not happen, according to GEM. This was due to government intervention to keep ageing coal plants online.
Five coal-power plants have been told to remain online through federal “emergency” orders, for example, even as the coal fleet continues to face declining competitiveness.
Keeping these plants online has cost hundreds of millions of dollars and helped drive an annual increase in the average US household electricity prices of 7%, according to GEM.
Despite such measures, Trump has overseen a larger fall in coal-fired power capacity than any other US president, according to Carbon Brief analysis.
Meanwhile, according to new figures from the US Energy Information Administration, solar and wind both set new records for energy production in 2025.
Despite challenges with policy and wider fossil-fuel impacts, the underlying dynamic has shifted, says GEM, as “clean energy becomes more competitive and widely deployed” around the world.
It adds that this raises the prospect of “a more sustained decoupling between coal-capacity growth and generation, particularly if clean-energy deployment continues at current rates”.
