Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Drought in southern Africa
NATIONAL DISASTERS: An ongoing extreme drought in southern Africa is threatening millions of people with hunger, Sky News reported. According to Reuters, Zimbabwe has declared the drought a national disaster. The drought has also reached crisis levels in neighbouring Zambia and Malawi, with both countries declaring national disasters, the Associated Press said. Botswana, Angola, Mozambique and Madagascar are also affected, it added.
EL-NIÑO: Dry weather conditions linked to the El Niño weather pattern have worsened the drought, which emerged in its latest phase in mid-2023, Deutsche Welle reported. El Niño reached a peak in December, according to the World Meteorological Organization, but is still expected to result in above-normal temperatures until May, the outlet added. Scientists told Sky News that El Niño could be “amplifying the existing impacts of climate change”.
CALL FOR AID: Zimbabwe president Emmerson Mnangagwa said the country needs more than $2bn in aid to feed the millions of people facing hunger, the Associated Press reported. It added that the United Nations’ World Food Programme has already rolled out a food assistance programme targeting 2.7 million people.
Electric car sales slump
POOR QUARTER: The world’s top sellers of electric vehicles (EV), Elon Musk’s Tesla and Chinese rival BYD, reported sharp falls in sales in the first financial quarter of this year, adding to “concerns over the slowing shifts towards EVs”, the Financial Times reported. It added that both carmakers have repeatedly cut prices since the start of the year in a bid to stimulate demand.
DIRE FUTURE?: Tesla’s shares fell following the news, extending their 2024 slide to 33%, the second-worst showing in the S&P 500 stock market index, Bloomberg reported. The dip in sales comes amid a “sharp deterioration in growth” for US EVs, the New York Times said. However, Musk is mulling over the possibility of building a £3bn Tesla EV factory in India, the Daily Telegraph reported.
ELECTRIC SUBSIDIES: Only seven out of 500,000 EV charging stations have been built under a $7.5bn US government subsidy programme launched in 2021 and scheduled for completion by 2030, the Independent reported. The Federal Highway Administration told the Independent that “the slow pace has been deliberate, to avoid costly mistakes while navigating a brand-new law and building a network from scratch”.
Around the world
- SEARING HEAT: India’s national weather service has forecast “hotter-than-usual” temperatures for April to June, raising the risk of water shortages and crop damages, Bloomberg reported.
- UNUSUAL FIRES: Venezuela is battling a record number of wildfires – with satellites detecting more than 30,200 fires between January and March – as a climate change-driven drought consumes the Amazon rainforest region, according to Reuters.
- CLIMATE JUSTICE: Shell began its appeal against a ruling at The Hague that compelled it to slash its emissions by 45% by 2030, relative to 2019, the Financial Times reported. A judgement is expected in the second half of this year, the paper added.
- AID BY FOSSIL: White House officials have suggested that they are open to ending president Joe Biden’s pause on approvals of new liquefied natural gas (LNG) export terminals in order to get a Ukraine aid package through Congress, Reuters reported. A White House spokesperson denied the story.
- WARNING BELLS: According to a new study reported by the Guardian, a boom in mining projects for minerals needed in renewable energy technologies is now threatening up to a third of apes in Africa.
- STANDING TALL: A new analysis found that the number of trees lost in Brazil and Colombia was down “dramatically” in 2023 – falling by 39% – largely due to changes in political leadership in these nations, according to BBC News.
57
The number of fossil fuel and cement producers responsible for 80% of the world’s CO2 emissions from 2016-2022, according to the Carbon Majors project by non-profit thinktank InfluenceMap.
Latest climate research
- A study in npj Climate Action evaluated the perceptions of climate change among a selection of academics at a local university in Cameroon and suggested a framework to support educators as they help to foster critical thinking.
- The optimal location for North American birds has shifted northward by an average rate of 1.5km each year in response to climate change, a new study in Proceedings of the National Academy of Sciences found, representing a total distance moved of 82.5km over the past 55 years.
- A new study in Climate and Development investigated the “policy blind spots” around the contribution of women to rangeland cultivation in Tunisia and the effects of climate change on their livelihoods.

Captured
The UN climate change body, the UNFCCC, is largely funded by industrialised nations, such as the US, China, Japan, UK and France. However, these nations have not yet paid anything towards the UNFCCC’s core budget for this year, according to Carbon Brief analysis of UN data. This shortfall could be impacting the body’s functioning. For example, the UNFCCC recently cancelled this year’s Regional Climate Weeks, which are a “vital platform to express the concerns of people and communities most affected by climate change,” according to a comment piece by WaterAid’s Dulce Marrumbe published on Climate Home News. “The suspension of the Regional Climate Weeks is hugely disappointing news,” Marrumbe said.
Spotlight
How is Nigeria coping with extreme heat fuelled by climate change?
This week, Carbon Brief zooms in on how Nigerians are responding to the extreme heat affecting west Africa.
Since the start of this year, Africa’s most populous nation Nigeria has faced prolonged stretches of severe heat.
A recent quick-fire analysis found that the conditions in February, when temperatures exceeded 40C, were made 10 times more likely by human-caused climate change.
But the heat is still ongoing, with temperatures reaching a record 44.8C in Sokoto, a city in north-western Nigeria, on 1 April.
With comprehensive record-keeping of heat and its impacts lacking in Nigeria, Carbon Brief spoke to doctors, farmers and meteorologists about how this episode of extreme weather is affecting the country.
Health impacts
The impact of the heat is “catastrophic”, Dr Ugo Uguwanyi, a doctor in Abuja, Nigeria’s capital city, told Carbon Brief:
“Don’t even bother to step out from 10am to 6pm. And make sure you burn the diesel to power the air conditioning to be able to sleep at night.”
Information about the heatwave’s impact is limited, but this does not mean the weather conditions are not dangerous, according to the authors of the recent analysis into the role of climate change in Nigeria’s extreme heat. Rather, a lack of systematic reporting may obscure what they described as a “silent killer”.
In mid-February, the Nigerian Meteorological Agency (NiMet) issued a public forecast warning on the prolonged heatwave.
The agency advised citizens to stay hydrated, wear light clothing and avoid direct exposure to high temperatures during peak periods. A group of Nigerian doctors also issued safety tips.
NiMet’s director of Weather Forecast Services, Vincent Weli, had advised that a state of emergency be declared in states most affected by the heatwave and workers be allowed to take breaks between noon and 3pm. Speaking to Nigeria’s Channels Television, Weli said:
“Of course, you know, with high temperature, cognitive development will be affected and productivity will be affected. There will be a loss of concentration.”
However, no such directive has yet been issued by state governments.
Agricultural and workforce impacts
Meanwhile, in Lagos, Nigeria’s most populated city, ride-hailing drivers are operating under melting conditions, stuck between preserving their health or livelihood, according to a Rest of World report.
The heatwave is also expected to reduce agricultural productivity, a sector that contributes about 22% to Nigeria’s gross domestic product (GDP) and accounts for more than a third of total employment.
Wasiu Adeniyi Ibrahim, a meteorologist from NiMet, told Carbon Brief:
“Heatwaves can reduce agricultural productivity by causing heat stress to crops and livestock.”
There is not a lot of data on how the current heat is affecting agriculture in Nigeria.
However, the national secretary of the All Farmers Association of Nigeria, Yunusa Halidu, told Carbon Brief that its members expect the heatwave to affect productivity yield this year. He said:
“The heat is extreme this year, although we have been expecting it, as we work with the Nigerian Meteorological Agency. We know it is global warming and we are working to see how we can mitigate the effects.”

REPORT: The Hidden Risks of Plastic Pouches for Baby Food
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.
Sign the petition for a strong Global Plastics Treaty
Governments around the world are now negotiating a Global Plastics Treaty – an agreement that could solve the planetary crisis brought by runaway plastic production. Let’s end the age of plastic – sign the petition for a strong Global Plastics Treaty now.

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.

New coal plants hit ‘10-year’ global high in 2025 – but power output still fell
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”.
