Prime Minister Keir Starmer has announced fresh climate change targets at a global summit, saying he wants the UK to lead on cutting climate emissions.
The UK will now aim for an 81% cut in its emissions by 2035, he told the UN conference of parties (COP29) in Azerbaijan.
The target updates a 78% pledge by 2035 under the previous Conservative government, although that also included international aviation and shipping emissions, and goes beyond another pledge of a 68% reduction by 2030.
Sir Keir insisted the government would not “tell people how to live their lives” but the target was vital to the UK’s future prosperity and energy security.
The prime minister said the new target was based on recommendations from the UK’s independent climate change committee (CCC) aimed at limiting global warming to 1.5C compared to levels in 1990.
Sir Keir would not be drawn on his views about president-elect Donald Trump, who has promised to cut climate rules during his election campaign.
He said: “Make no mistake, the race is on for the clean energy jobs of the future, the economy of tomorrow, and I don’t want to be in the middle of the pack – I want to get ahead of the game”.
Announcing a £1bn investment in a wind turbine project in Hull, which he said was creating 1,300 local jobs, Starmer said the world was standing at a “critical juncture in the climate crisis”.
The UK has called for other countries to match the new target, following stark warnings from the United Nations that the world is on course for a 3.1C rise without further cuts.
The latest target is broadly in line with the UK’s legally-binding carbon-cutting path towards net zero emissions by 2050, contained in the 2015 Paris Agreement.
Since taking power in July, Labour has ended an effective ban on new onshore wind projects and pledged not to issue any new oil and gas exploration licenses in the North Sea, as well as closing the UK’s last coal power plant in September.
The switch towards greener energy has already halved the UK’s annual greenhouse gas emissions since 1990 – but the CCC has previously said further reductions will be difficult without lifestyle changes.
The government advisers said taxes on meat and dairy might be needed if people do not voluntarily reduce their consumption of the products, and there should be moves to phase out the use of petrol cars.
Speaking at the summit, Sir Keir said the new UK target would be “difficult” but “achievable”, and he wanted government to “tread lightly on people’s lives”.
“It’s not about telling people how to live their lives – I’m not interested in that,” he added.
“I am interested in making sure their energy bills are stable, that we’ve got energy independence, and that we also along the way pick up the next generation of jobs.”
All countries who have signed up to the Paris Agreement should submit their latest carbon reduction targets by a deadline of February next year and a copy of that memo, known as the Information to facilitate Clarity, Transparency and Understanding (ICTU), will be presented to MPs before then.
