Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Global heatwave
SOUTH ASIA: Extended and severe heatwaves that continue to grip 50% of northwest India have claimed at least 110 lives and caused 40,000 to suffer from suspected heatstroke, the Hindustan Times reported. Delhi recorded its highest ever minimum temperature in a 55- year record this week, when night-time temperatures did not drop below 35.2C, the Hindu reported. Reuters reported that a senior government official said “Indian cities have become heat traps” due to unbalanced urban growth reducing water availability.
EAST ASIA: Meanwhile, state-run newspaper China Daily reported that the nation is “experiencing more frequent and intense heatwaves due to global warming”, according to China’s National Climate Centre. It added that the average heatwave starting date has advanced by 2.5 days per decade. The Hong Kong-based South China Morning Post reported that extreme weather has continued in China this week, including deadly torrential rain and drought conditions.
DEADLY PILGRIMAGE: In the Middle East, more than 1,000 hajj pilgrims have reportedly died amid scorching heat in the holy city of Mecca in Saudi Arabia, Sky News reported. Agence France-Presse said that temperatures reached 51.8C in Mecca as around 1.8 million people took part in the “days-long, mostly outdoor” pilgrimage. It added that the death toll is expected to rise further as many continue to search for family members.
US FURNACE: Tens of millions of people in the US were under dangerous heat warnings this week as some cities faced record-breaking temperatures, the Associated Press reported. The Guardian reported that about 80% of the country’s population are experiencing “a kind of heatwave not seen in decades”, which brought prolonged periods of temperatures above 32.2C, “under a weather phenomenon known as a heat dome”.
‘BRUTAL’ EUROPE: After registering Europe’s highest recorded temperature of 48.8C in 2021, Sicily is again having to turn away tourists as “brutal heatwaves” have led to crops dying and farm animals facing slaughter, reported the Times. Elsewhere in Europe, a wildfire near Athens, Greece forced dozens to flee their homes, reported Reuters. Officials said the fire was the result of arson and spread quickly in hot, dry conditions, the newswire added.
Around the world
- G7 DROPPED: The G7 group of major economies has pledged to speed up their transition away from fossil fuels at a summit in Italy, Reuters reported. It added that activists were unhappy at the pace of progress.
- RECORD RENEWABLES: Wind and solar combined added more new energy to the global mix than any other source for the first time in history in 2023, according to Carbon Brief analysis of newly released data.
- PEAKING CHINA: China has reduced power from fossil fuels and boosted solar and hydro, “feeding hopes that the world’s biggest polluter may have peaked emissions years before its own deadline”, Bloomberg reported. Carbon Brief analysis in May found China may have peaked its emissions in 2023.
- CONFLICT DAMAGE: A UN report found that Israel’s assault on Gaza has caused environmental damage, “deeply harming people’s health, food security and Gaza’s resilience”, according to Reuters.
- NATURE WIN: After months of stagnation, the EU’s nature restoration law was voted through by ministers at the EU council, the Financial Times reported.
- STRANDED BY SLIDES: Al Jazeera reported that landslides triggered by heavy rain have left hundreds of thousands of people stranded and at least 15 dead in India and Bangladesh.
$1.1-1.3 trillion
The amount of climate finance developing countries at Bonn want developed countries to provide to them every year, according to Climate Home News.
Latest climate research
- New research in Environmental Research Letters suggested that the Arctic will be “ice-free” – that is, where sea ice extent drops below one million square kilometres – at the end of summer when global warming reaches between 1.5C and 2.2C above pre-industrial levels.
- Ocean-based carbon dioxide removal techniques such as ocean alkalinity enhancement have been “overlooked”, a research paper in Environmental Research Letters argued.
- The extreme heat that hit southwestern US, Mexico and Central America from May to June this year was 35 times more likely and 1.4C hotter due to climate change, new analysis by the World Weather Attribution network found.

Captured

New Carbon Brief analysis by Dr Simon Evans revealed that the UK’s energy bills were £22bn higher over the past decade than they would have been if successive Conservative governments had not cut the “green crap” by rolling back climate policies for areas such as insulating homes, new home building standards and onshore wind and solar growth. The chart above shows how lack of progress on various climate measures has added to UK energy bills from 2015-2024. The cutting back on green measures has also raised net gas imports by a third, making the UK more reliant on gas imports and leaving customers more exposed to high gas prices, the analysis said. Carbon Brief is continuing to track where UK parties stand on climate change and energy ahead of the country’s general election.
Spotlight
Can beavers help the UK adapt to climate change?
This week, Carbon Brief looks at the evidence on the potential pros and pitfalls of reintroducing beavers to help deal with rising climate risks in the UK.
From Narnia to the Ice Age franchise, beavers have a spot as a charismatic, comical and – until recent years – somewhat mythical animal in British popular culture.
Beavers were hunted to extinction in Britain 400 years ago, and to near extinction in Europe. Memory of their presence in Britain survives in place names, such as Beverley Brook in London.
Given their reputation, it is perhaps surprising that they have also been called “climate heroes”, “ecosystem engineers” and, more recently, “heatwave heroes”.
Such labels come from beavers’ ability to alter the landscapes around them, offering benefits such as lowering flood risk or providing new habitats for biodiversity.
It is these benefits that have seen beavers reintroduced to some areas of England and Scotland.
Climate and biodiversity benefits
Beavers are a keystone species, which means they have an inordinately large impact on their natural environment, with the ability to define their ecosystem.
They use their huge front teeth to fell trees, building dams and lodges,which subsequently hold back huge volumes of water to create a wetland habitat.
The animals do this to create their ideal environment – one with deep water so they can hide from predators. However, they also inadvertently create an oasis for a variety of wildlife.

Earlier this week, the Guardian reported that, after living in the wild for 15 years in Scotland, beavers create the “perfect conditions” for endangered native water voles to flourish.
Prof Richard Brazier, director of the Centre for Resilience in Environment, Water and Waste at the University of Exeter, said the main climate benefits beavers can provide were enhancing water and carbon storage. He told Carbon Brief:
“Beaver ponds store a lot of carbon, nitrogen and phosphorus. Beavers coppice [chop down] species like willow. When they regrow, it enhances carbon storage in the landscape.”
Climate change is making many types of extreme weather events, including droughts, more likely and more intense.
Beaver wetlands are known to remain oases in otherwise cracked, dry land. The water stored in beaver ponds slowly seeps into the surrounding soil during dry periods, keeping the area green.
In the US, research found that wetland habitats created by beavers are resistant to wildfires because the area is simply too wet to burn.
Perhaps the most well-known link between beavers and climate adaptation is their alleviation of flood risks.
In March, the UK government’s Environment Agency reported that, after five years of beaver activity in an enclosed area, the impact of flooding was reduced in Spains Hall Estate, Essex.
In Devon, scientists last month concluded a 10-year study finding that beavers are “having a positive impact on flood and drought alleviation” by storing 24m litres of water and reducing storm flows by 30% during heavy rainfall, keeping downstream homes safer from floods.
Human-animal conflict
Other studies on beavers have warned that friction between the animals and adjacent landowners must be a central consideration for successful reintroduction.
Under certain circumstances, their natural engineering can interfere with human infrastructure and farming.
Some farmers are concerned that beaver activity causes flooding and damage to crops. Others worry that tree felling could cause damage to houses nearby.
Occasionally, beaver burrows can collapse, and damage property or machinery nearby.
Brazier told Carbon Brief that “tensions can arise” when humans “try to resist the natural instinct of the beaver to create deep water pools”. He added:
“If there are downsides, these relate to the ways in which, by building dams, beavers put water back on floodplains, when humans tend to want to remove this water, such as for agriculture. But these low-lying landscapes are floodplains, they are meant to be underwater periodically, and indeed, whether beavers are reintroduced or not, they will be more inundated by flooding in the future, under climate change scenarios.”
Beaver releases
Despite opposition from some groups, momentum has been gradually building for beavers’ return to the wild.
It is still illegal to reintroduce beavers in Britain without a licence.
In 2009, illegal releases were made in Tayside, Scotland and Devon, England. It is unknown where the beavers came from.
The first licence for beaver reintroduction was given for an enclosed area in Ham Fen in Kent in 2001.
In 2009, the first licensed reintroduction of beavers into the wild occurred in Knapdale, Scotland, with the animals shipped in from Norway.
In 2021, the government allowed the illegally released beavers in Devon to remain wild.
Beavers are also being reintroduced into cities. They were reintroduced in Enfield, north London in 2022 – and it was there that the first kit was born in London last summer.
Beavers were declared a native species in 2016 in Scotland and in 2022 in England.
However, the UK government is yet to introduce a national strategy for beaver reintroduction – “missing a huge opportunity to deliver profound benefits”, according to Brazier.

Will new UK PM’s green measures at home cause climate finance pain overseas?
Britain’s new prime minister announced in his first week that he will cut the cost of public transport and electricity, making lower-emission technologies like bus travel, electric vehicles and heat pumps more affordable for voters. But some of the funding for those policies will come from the budget for international climate finance, the government has said, raising concerns about fairness.
Former Manchester Mayor Andy Burnham took over from Keir Starmer as Labour Party leader and prime minister on Monday, appointing climate advocates Ed Miliband as foreign and development minister and Miatta Fahnbulleh as climate and energy minister.
On Tuesday, Burnham said his government would cut the value added tax (VAT) households and some small businesses pay on their electricity bills from 5% to zero from October 1, saving households £45 ($60) a year.
On Wednesday, he said the maximum fare bus companies in England can charge for a single journey will be reduced from £3 ($4) to £2 ($2.67) from January 1, 2027. The government said the subsidies to achieve this would be mostly funded by switching money set aside for overseas climate finance projects from grants to loans. It did not give further information in its announcement, while the UK’s transport minister told Sky News the plan is still being worked out.
The floated changes to the climate finance budget were immediately criticised by groups working on climate justice for developing countries, including Bond, the UK network for NGOs, which described the decision as “disappointing”.
“Robbing Peter to pay Paul is not the answer and pitches marginalised communities in the UK against marginalised communities in lower-income and climate-vulnerable countries,” BOND CEO Romilly Greenhill said in a statement. “Climate finance must not worsen the debt burden of countries that are already suffering the worst – and most costly – impacts of a climate crisis they did not cause.”
Hunt for money
Burnham promoted both policies as measures to combat the rising cost of living and “give people breathing space”, with climate campaigners and industry groups noting they are also likely to reduce the UK’s climate-heating emissions by encouraging bus travel and the use of electric vehicles and heating.
But thorny questions remain over how the policies will be paid for. The government said Tuesday’s VAT cut for electricity would be funded by scrapping the previous government’s digital ID programme, but Darren Jones, a former minister involved with that policy, said it had been “unfunded” – a statement that dominated media coverage.
A day later, the government said the new bus fare cap would cost £454 million ($606m). Transport minister Heidi Alexander told Sky News that £54 million would be taken from an under-spend in the budget of the Department for Energy Security and Net Zero (DESNZ) and £400 million would come from changing unspecified international climate finance from grants to loans. The details “still need to be worked through”, she said, adding that the government “had wanted to make an announcement today”.
Mohamed Adow, director of Nairobi-based think-tank Power Shift Africa, said “climate finance was never meant to be a pot of money that governments raid when they need to pay for domestic spending”.
DESNZ had not responded to a request for comment at the time of publication. “We’re not wanting to fleece anyone here, and we actually want to maximise the development potential of this money that is available,” minister Alexander said in her TV interview.

Aside from the controversy over their funding, the policies themselves were widely welcomed by climate campaigners. Jess Ralston, energy lead at the Energy and Climate Intelligence Unit (ECIU), said the tax cut on electricity bills “could help households to switch to electric heat pumps, protecting UK homes from becoming ever more exposed to the whims of Putin and Trump when turning on their gas boiler”.
The last few months have seen global momentum build behind electrification, spurred by the US-Iran war disrupting oil and gas supplies and driving up prices. The Turkish and Australian COP31 presidencies have announced a global target to boost electrification, backed by the European Union, Canada, Philippines, UK and others.
Campaigners call for lower power prices
While reaction to the VAT cut was supportive, some questioned whether £45 a year of savings per household is enough and called for more measures to cut electricity bills.
Friends of the Earth’s energy lead Imogen Dow said those on the lowest incomes should be given cheaper electricity through a “social tariff” and the Institute for Public Policy Research (IPPR) think-tank – which is close to the Labour Party – said levies on energy bills should be shifted to general taxation.
Matthew Paterson, a politics professor at Manchester University, told Climate Home News that the most effective way to reduce electricity bills is to take on the UK’s private electricity companies, while consumer-oriented measures like the VAT cut are “tinkering around the edges”.
Jarrod Birch, head of policy and public affairs for the EV charging industry association Charge UK, said that while the policy would make home-charging cheaper, people who charge their vehicles at public points will still have to pay 20% VAT. The UK’s tax authority is fighting a court ruling that ordered it to reduce the tax motorists pay on public chargers to the current household rate of 5%.
Further measures will be the responsibility of Secretary of State for Energy Security and Net Zero Miatta Fahnbulleh, who is relatively new to politics after a career at left-wing, pro-climate think tanks the IPPR and the New Economics Foundation.

Michael Jacobs, political economy professor at Sheffield University and former adviser to UK Labour prime minister Gordon Brown, said Fahnbulleh would be a “climate advocate” who would continue the “progressive climate agenda” of her predecessor Ed Miliband.
“She’s a very creative policy wonk so I expect there to be lots of policy innovation under her,” he said, “I think she will be looking at new ways to encourage take-up of heat pumps and domestic batteries.”
Aid budget in Miliband’s hands
Despite reports he could be made finance minister, Miliband has been appointed Secretary of State for Foreign and Commonwealth Affairs. Miliband has attended many climate COP meetings over several decades, most recently representing the UK at COP29 and COP30, and has been targeted by the right-wing media for his support for climate action and opposition to new oil and gas drilling in the UK’s part of the North Sea.
In his new role, Miliband will be responsible for the UK’s overseas aid budget including its international climate finance, which the Starmer government had slashed to fund increases in defence spending.
UK cuts support for climate action abroad to fund military instead
Jacobs said he expected Miliband to prioritise climate and development in the UK’s foreign policy and to push Burnham and new finance minister John Healey to reverse Starmer’s aid cuts.
But there are fears Healey could try to cut the aid budget further to fund the military. Healey was a surprise pick for Chancellor of the Exchequer and grabbed headlines when he resigned as Starmer’s defence minister in June over what he saw as insufficient defence spending.

Greenpeace launches legal challenge against Australia’s biggest meat company
AMSTERDAM, Netherlands, 22 July 2026 – Greenpeace Netherlands has launched legal proceedings against a multi-billion-dollar global expansion plan by the biggest meat producer in Australia, JBS, in an escalation of climate litigation against the livestock industry.
Greenpeace petitioned a Dutch court to compel the meat giant to disclose information in order to challenge its business policies in court, including a US$6 billion global expansion, for which almost half is earmarked for Nigeria.
Elizabeth Atieno, Food Campaigner at Greenpeace Africa, said: “JBS’ meat empire expanded hand-in-glove with Amazon destruction, colossal emissions, human rights and corruption scandals, all with barely a semblance of transparency. This is the business model it wants to export to sub-Saharan Africa. JBS promises food security, but its expansion in Nigeria risks causing irreversible environmental damage and the displacement of smallholder farmers to line the pockets of wealthy global elites.
“Nigerians know well from the legacy of companies like Shell the destructive impact wrought by unchecked corporate power. As Greenpeace Africa has argued before the African Court of Human Rights, states with jurisdiction over multinationals must hold those corporate actors accountable – wherever they operate in the world. We welcome this bold legal action: the Netherlands and other European states must not be safe havens for corporations like JBS seeking to evade their responsibilities.”
In light of JBS’ longstanding failure to publish accurate and reliable information on its climate, nature and human rights impacts or its expansion plans, Greenpeace Netherlands views accessing this data as a necessary precursor to formal litigation in order to support its case. The case has the potential to be the first climate litigation of this scale against the livestock industry. This could set a major precedent for future legal challenges against the industrial agriculture sector, a major source of global emissions, particularly of methane, a potent greenhouse gas, responsible for 0.5°C of warming since the Industrial Revolution.[1]
JBS, via its subsidiary JBS Foods Australia, is the largest meat and food processing company in Australia. With a weekly processing capacity of over 50,000 cattle, it accounts for almost a quarter of all beef processing in the country, as well as a significant presence in the lamb, pork and farmed fish markets. [2] In 2022, ABC’s Four Corners accused the company of ‘repeatedly failing to protect its workers from horrific injuries.’ [3]
Marieke Vellekoop, Executive Director at Greenpeace Netherlands, said “In a month where JBS has thrown its flagship environmental commitments onto the scrap heap, JBS’ disdain for basic transparency only adds to the impression that this meat giant has something to hide and is desperate to prevent its expansion plans from going public. We were hoping we wouldn’t have to trouble a judge with this matter, but JBS has left us no choice but to seek our right to information through the Dutch courts.
“JBS appears to believe that despite moving to the Netherlands, our rules do not apply to it. This legal action aims to prove it wrong – and lay the ground for a first major climate and nature lawsuit against the dangerous expansion of the global meat industry.“
At the centre of the dispute is JBS’ planned US$ 2.5 billion investment in industrial livestock production in Nigeria.[2] Civil society groups in Nigeria have raised urgent warnings that the aggressive expansion will threaten local food security, drive regional instability, and accelerate ecological degradation. There is no available evidence that JBS has conducted any impact assessments or community consultations in Nigeria, and local efforts to gather more information via Freedom of Information requests have reportedly been ignored.[3]
The escalation to the courts follows the refusal of JBS, the world’s largest meat company, to comply with a formal disclosure demand delivered by Greenpeace Netherlands in April. The environmental group is utilising new Dutch legislation, which grants parties with a legitimate interest the right to demand access to specific corporate data necessary to build litigation against Dutch companies.[4]
Greenpeace Netherlands’ lawyers allege that JBS’ historic business practices and future expansion plans are inconsistent with the company’s climate and biodiversity obligations and represent a breach of its Dutch duty of care, which requires companies to act in line with international human rights law.[5]
If the court rules in favor of Greenpeace Netherlands, it is entitled to seek the required information in the form of documents and from senior JBS figures under oath, raising the prospect of the Batista brothers being forced to testify in Dutch court. JBS reincorporated as a Dutch entity (JBS N.V.) last year to facilitate a dual listing on the New York Stock Exchange.
In April, JBS was forced to temporarily suspend its first annual general meeting since moving its headquarters to Amsterdam after it was disrupted by dozens of Greenpeace Netherlands activists.
Last week, JBS scrapped two flagship commitments to reach Net Zero emissions by 2040 and eradicate deforestation from its supply chain. It also removed any explicit reference to Indigenous lands from all of its current policies. Greenpeace Netherlands is concerned this indicates JBS is seeking to expand unconstrained by the climate, nature and human rights impacts of its business.

Notes:
[1] The livestock sector is estimated to be responsible for 31% of global methane emissions (more than oil and gas operations). In comparison to CO2, methane is shorter lived (around 12 years) but has a much stronger ability to trap heat in the atmosphere over its lifetime: it has approximately 80 times more climate impact than CO2 when measured over 20 years. This means that changes in methane emissions have a more rapid effect on the climate than changes in CO2. See Greenpeace Netherlands letter to JBS dated 30 April 2026.

“Next year is too late for regulations”: Beetaloo Energy’s 2GW gas-powered AI data centre a “disaster proposal” destined to cause climate chaos
SYDNEY, Wednesday 22 July 2026 — Beetaloo Energy has secured land from the NT Government for a massive $40 billion “hyperscale” AI data centre near Darwin, which would be powered by 2 gigawatts (GW) of gas power fracked directly from the Beetaloo basin, prompting calls from Greenpeace for urgent federal legislation.
The proposal marks a dangerous escalation in the AI data centre industry’s expansion, which threatens to entrench fossil fuel infrastructure for decades and put immense pressure on the region’s fragile water resources — while continuing to be unregulated.
Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said: “This disaster proposal for a 2GW gas-powered AI data centre in the NT is a shocking example of the unchecked expansion of hyperscale data centres in Australia. It is also, critically, more evidence for the urgent need for a moratorium on all new data centres until strong, binding regulations are put in place to protect our communities and climate.
“This proposal mirrors the frenzied, unchecked expansion currently wreaking havoc on communities in the US. We are seeing cowboy data centre operators treat Australia like a playground, steam-rolling ahead with projects that would lock down precious water resources and spike emissions, despite the overwhelming community opposition.
“Every day, more councils, communities and environmental groups are joining Greenpeace’s call for a moratorium on data centres, yet as of today there is still no system of safeguards or rules in place to regulate these companies.
“While Beetaloo Energy and the NT Government prepare to bulldoze ahead with this climate and water disaster, the Prime Minister is asleep at the wheel, promising to legislate a vague set of standards next year.
“Next year is too late, and anything less than mandating data centres cover their own energy demand, and then some, with new renewable energy is not enough.”
