The Guardian view on Trump’s planet-wrecking plans: the UK government’s resolve will be tested

The new president’s disruptive policies will challenge Sir Keir Starmer’s green goals. But with strong leadership he could enhance Britain’s global influence

Donald Trump’s electoral earthquake in America will complicate Sir Keir Starmer’s plans. Nowhere will the shock of Mr Trump’s win be more intensely felt than in environmental policy. His stance on climate – advocating a US exit from the Paris climate agreement and rallying behind “drill baby drill” – is more disruptive than constructive. This should concentrate Sir Keir’s mind as he heads to Cop29, the UN’s annual climate summit, in Baku, Azerbaijan.

At last year’s conference, world leaders agreed to “transition away” from fossil fuels in a just and orderly manner for the first time. Mr Trump, however, dismisses the climate crisis as a hoax. With this year likely to be the hottest on record, the devastating effects of global heating are undeniable, as extreme weather batters the planet. Mr Trump may ignore the facts, but the trail of climate-related chaos and destruction speaks for itself.

This ought to steel the prime minister’s resolve. Mr Trump’s plan to give the US an advantage in world trade through tariffs will complicate Labour’s goals of greening the economy, producing zero-carbon electricity, and cutting energy prices. The worst move Sir Keir could make would be to listen to rightwing voices arguing that if other nations are dropping green commitments, so should Britain. That would be a serious misstep, as leadership on climate not only reduces Britain’s carbon emissions but builds strategic alliances around the globe.

Mr Trump’s trade war threatens to disrupt supply chains, hike costs, jeopardise Britain’s green transition and stall its growth. His push for higher Nato defence spending could, in the UK, divert public funds from environmental initiatives. But this misses the point: Britain’s growth will be turbocharged by embracing green energy, leveraging its strengths in areas like offshore wind. Plus, most voters see a green shift as a path to lower energy costs and a stronger economy – a cause Sir Keir would be smart to champion.

The prime minister should double down on the plans of his energy secretary, Ed Miliband, rather than waver in the face of Trumpian pressure that prioritises short-term gains over a cleaner future. Mr Trump’s stance may also soften. He wants to gut Joe Biden’s Inflation Reduction Act and eliminate its clean tech subsidies. Yet most investment under the act has flowed to red and swing states in America’s south and midwest that voted for Mr Trump. Republican leaders in those states have vowed to protect these projects.

The profits of Elon Musk’s electric vehicle company Tesla would gain under Mr Trump’s deregulatory agenda. Mr Musk was $26bn richer the day after Mr Trump won. That reveals how the world’s richest person’s wealth is tied to political forces undermining green protections. Once a critic, Mr Musk now cosies up to Mr Trump. The quid pro quo is clear: Mr Trump, who once mocked electric cars, pandered to Mr Musk, telling a rally in August: “I’m for electric cars … because Elon [Musk] endorsed me.”

Mr Trump’s absence from future Cop meetings would be a mixed blessing. On one hand, he would hinder proceedings rather than help them. But having Mr Trump in the room might be preferable to him causing trouble from the outside. With some European leaders backing off green leadership due to domestic challenges, and others likely to follow Mr Trump’s lead, Sir Keir has a chance to step up on the world stage. This is a popular position at home. It would also be welcomed by his embattled counterparts on the continent – and beyond.
