The UK looked set to backtrack Wednesday on policies aimed at achieving net zero emissions by 2050 with Prime Minister Rishi Sunak expected to water down some of the government’s green commitments. The move comes amid growing concern over the potential financial cost of the government’s policies to achieve net zero carbon emissions by mid-century. A general election is expected next year and Sunak’s Conservative Party is trailing in the polls behind the Labour opposition amid a cost-of-living crisis that has seen food and housing costs spiral. Sunak will deliver a speech at Downing Street later on Wednesday. According to British media reports, the premier in particular wants to water down plans to phase out gas boilers from 2035 and delay the ban on the sale of new petrol and diesel cars due in 2030. In a statement late Tuesday he said that while the government was committed to the net zero target, it would try to achieve it “in a better, more proportionate way”. The Conservative’s narrow win in a west London by-election in July — largely put down to a campaign against the expansion of a vehicle pollution toll zone in the capital by Labour mayor Sadiq Khan — triggered calls within the party to rethink climate commitments. Sunak said politicians “of all stripes have not been honest about costs and trade-offs” and that he would “put the long-term interests of our country before the short-term political needs of the moment”. Interior minister Suella Braverman told Sky News on Wednesday morning that “we’re not going to save the planet by bankrupting the British people”. “We absolutely remain committed to delivering net zero by 2050 in line with our international agreements,” she said, adding that “we also need to adopt an approach of pragmatism and proportionality”. “We need to put economic growth first, we need to put household costs and budgets first, we need to put the cost of living first,” she added. The government’s expected net zero rethink sparked anger among opposition lawmakers, environmental campaigners, the car industry, and some Conservative MPs, setting up a possible rift in Sunak’s party. In July, Sunak approved hundreds of new oil and gas licenses in the North Sea off Britain’s east coast, angering environmentalists. Former COP26 president and Conservative lawmaker Alok Sharma warned that “for any party to resile from this agenda will not help economically or electorally.” Chris Skidmore, a Conservative former energy minister who recently led a review on net zero for the government, said Sunak “still has time to think again and not make the greatest mistake of his premiership.” Reports suggested that some MPs may even be preparing letters of no confidence should Sunak go ahead with the move. Green Party MP Caroline Lucas said, “This decision would be economically illiterate, historically inaccurate, and environmentally bone-headed.” Ed Miliband, Labour’s spokesman for energy, called it a “complete farce from a Tory government that literally does not know what they are doing day to day.” Criticism also came from industry, with Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders, saying the UK should be a “leader in zero-emission mobility” but “clear, consistent” messaging is required from the government for consumers to want to switch to electric vehicles. “Confusion and uncertainty will only hold them back,” Hawes added. Green campaigners were angered too, as Rebecca Newsom, head of politics at Greenpeace UK, saying that “Britain has gone from leader to laggard on climate change and further planned U-turns leaked last night will only hasten our waning influence on the world stage.” Britain’s interior minister said on Wednesday the country needed to take a pragmatic approach to reaching net zero because it could not “save the planet by bankrupting the British people”. The comment by Suella Braverman comes ahead of a speech by Prime Minister Rishi Sunak this week where he is expected to delay some of the government policies which underpin Britain’s long-term plan to reach net zero emissions by 2050. “We have to adopt a pragmatic approach, a proportionate approach and one that also serves our goals, and we’re not going to save the planet by bankrupting the British people,” Braverman told Times Radio. Britain was the first major economy to create a legally binding target to bring greenhouse gas emissions to net zero by 2050 and it was quick to build up its renewable energy capacity in earlier years. But Sunak’s government has recently appeared to waver on some of the measures needed to hit that target as the cost of decarbonising everything from travel to the heating of homes has crystalised during a prolonged cost-of-living crisis. With a parliamentary election looming next year, Sunak sees scaling back some green policies as a way to win over swing voters – a striking reversal for a country which until recently was a self-proclaimed leader in climate policy. One area of speculation is that the government could delay the introduction of a ban on the sale of new petrol and diesel cars to 2035 from the current target of 2030. That would put Britain in line with the European Union which has also adopted a 2035 target, but such a move could dismay the car industry which is looking for certainty as it spends heavily to switch to the production of electric vehicles. With speculation swirling, Sunak released a statement late on Tuesday saying Britain needed to move towards its net zero goals in a “more proportionate way” and that he would set out an “important long-term decision” this week. Chris Skidmore, a former energy minister who signed Britain’s 2050 net zero commitment into law in 2019 but has since left government and recently led a review into the country’s progress towards its targets, said any delay would hit future jobs and investment.
