Welcome to Carbon Brief’s DeBriefed. 
An essential guide to the week’s key developments relating to climate change.

This week

Absolute State of the Union

‘DRILL, BABY’: US president Donald Trump “doubled down on his ‘drill, baby, drill’ agenda” in his State of the Union (SOTU) address, said the Los Angeles Times. He “tout[ed] his support of the fossil-fuel industry and renew[ed] his focus on electricity affordability”, reported the Financial Times. Trump also attacked the “green new scam”, noted Carbon Brief’s SOTU tracker.

COAL REPRIEVE: Earlier in the week, the Trump administration had watered down limits on mercury pollution from coal-fired power plants, reported the Financial Times. It remains “unclear” if this will be enough to prevent the decline of coal power, said Bloomberg, in the face of lower-cost gas and renewables. Reuters noted that US coal plants are “ageing”.

OIL STAY: The US Supreme Court agreed to hear arguments brought by the oil industry in a “major lawsuit”, reported the New York Times. The newspaper said the firms are attempting to head off dozens of other lawsuits at state level, relating to their role in global warming.

SHIP-SHILLING: The Trump administration is working to “kill” a global carbon levy on shipping “permanently”, reported Politico, after succeeding in delaying the measure late last year. The Guardian said US “bullying” could be “paying off”, after Panama signalled it was reversing its support for the levy in a proposal submitted to the UN shipping body.

Around the world

• RARE EARTHS: The governments of Brazil and India signed a deal on rare earths, said the Times of India, as well as agreeing to collaborate on renewable energy.
• HEAT ROLLBACK: German homes will be allowed to continue installing gas and oil heating, under watered-down government plans covered by Clean Energy Wire.
• BRAZIL FLOODS: At least 53 people died in floods in the state of Minas Gerais, after some areas saw 170mm of rain in a few hours, reported CNN Brasil.
• ITALY’S ATTACK: Italy is calling for the EU to “suspend” its emissions trading system (ETS) ahead of a review later this year, said Politico.
• COOKSTOVE CREDITS: The first-ever carbon credits under the Paris Agreement have been issued to a cookstove project in Myanmar, said Climate Home News.
• SAUDI SOLAR: Turkey has signed a “major” solar deal that will see Saudi firm ACWA building 2 gigawatts in the country, according to Agence France-Presse.

Captured

The constituency of Richard Tice MP, the climate-sceptic deputy leader of Reform UK, is the second-largest recipient of flood defence spending in England, according to new Carbon Brief analysis. Overall, the funding is disproportionately targeted at coastal and urban areas, many of which have Conservative or Liberal Democrat MPs.

Spotlight

Is there really a UK ‘greenlash’?

This week, after a historic Green Party byelection win, Carbon Brief looks at whether there really is a “greenlash” against climate policy in the UK.

Over the past year, the UK’s political consensus on climate change has been shattered.

Yet despite a sharp turn against climate action among right-wing politicians and right-leaning media outlets, UK public support for climate action remains strong.

Prof Federica Genovese, who studies climate politics at the University of Oxford, told Carbon Brief: 

“The current ‘war’ on green policy is mostly driven by media and political elites, not by the public.”

Indeed, there is still a greater than two-to-one majority among the UK public in favour of the country’s legally binding target to reach net-zero emissions by 2050, as shown below.

Steve Akehurst, director of public-opinion research initiative Persuasion UK, also noted the growing divide between the public and “elites”. He told Carbon Brief:

“The biggest movement is, without doubt, in media and elite opinion. There is a bit more polarisation and opposition [to climate action] among voters, but it’s typically no more than 20-25% and mostly confined within core Reform voters.”

Conservative gear shift

For decades, the UK had enjoyed strong, cross-party political support for climate action.

Lord Deben, the Conservative peer and former chair of the Climate Change Committee, told Carbon Brief that the UK’s landmark 2008 Climate Change Act had been born of this cross-party consensus, saying “all parties supported it”.

Since their landslide loss at the 2024 election, however, the Conservatives have turned against the UK’s target of net-zero emissions by 2050, which they legislated for in 2019.

Curiously, while opposition to net-zero has surged among Conservative MPs, there is majority support for the target among those that plan to vote for the party, as shown below.

Dr Adam Corner, advisor to the Climate Barometer initiative that tracks public opinion on climate change, told Carbon Brief that those who currently plan to vote Reform are the only segment who “tend to be more opposed to net-zero goals”. He said:

“Despite the rise in hostile media coverage and the collapse of the political consensus, we find that public support for the net-zero by 2050 target is plateauing – not plummeting.”

Reform, which rejects the scientific evidence on global warming and campaigns against net-zero, has been leading the polls for a year. (However, it was comfortably beaten by the Greens in yesterday’s Gorton and Denton byelection.)

Corner acknowledged that “some of the anti-net zero noise…[is] showing up in our data”, adding: 

“We see rising concerns about the near-term costs of policies and an uptick in people [falsely] attributing high energy bills to climate initiatives.”

But Akehurst said that, rather than a big fall in public support, there had been a drop in the “salience” of climate action:

“So many other issues [are] competing for their attention.”

UK newspapers published more editorials opposing climate action than supporting it for the first time on record in 2025, according to Carbon Brief analysis.

Global ‘greenlash’?

All of this sits against a challenging global backdrop, in which US president Donald Trump has been repeating climate-sceptic talking points and rolling back related policy.

At the same time, prominent figures have been calling for a change in climate strategy, sold variously as a “reset”, a “pivot”, as “realism”, or as “pragmatism”.

Genovese said that “far-right leaders have succeeded in the past 10 years in capturing net-zero as a poster child of things they are ‘fighting against’”.

She added that “much of this is fodder for conservative media and this whole ecosystem is essentially driving what we call the ‘greenlash’”.

Corner said the “disconnect” between elite views and the wider public “can create problems” – for example, “MPs consistently underestimate support for renewables”. He added:

“There is clearly a risk that the public starts to disengage too, if not enough positive voices are countering the negative ones.”

Watch, read, listen

TRUMP’S ‘PETROSTATE’: The US is becoming a “petrostate” that will be “sicker and poorer”, wrote Financial Times associate editor Rana Forohaar.

RHETORIC VS REALITY: Despite a “political mood [that] has darkened”, there is “more green stuff being installed than ever”, said New York Times columnist David Wallace-Wells.
CHINA’S ‘REVOLUTION’: The BBC’s Climate Question podcast reported from China on the “green energy revolution” taking place in the country.
