PM Rishi Sunak
Rishi Sunak is poised to ditch the 2030 ban on new petrol and diesel cars as he scales back costly green pledges.

In a dramatic policy shift, he is set to delay the switch to electric vehicles and slow the phasing-out of gas boilers. Pushing back the petrol and diesel ban from 2030 to 2035 would be a victory for the Mail's campaign to rethink the deadline.

The Prime Minister will set out the changes in a speech in which he will recommit to hitting 'net zero' carbon emissions by 2050, a target enshrined in law. But he will argue that the goal can be met with a more 'pragmatic' approach that does not force onerous changes on the public. Ministers believe the plan could help transform Tory fortunes and assist households struggling with the high cost of living.

Last night Mr Sunak said:
"Governments of all stripes have not been honest about costs and trade-offs. Instead they have taken the easy way out, saying we can have it all. This realism doesn't mean losing our ambition or abandoning our commitments. Far from it. I am proud that Britain is leading the world on climate change.

"We are committed to net zero by 2050 and the agreements we have made internationally - but doing so in a better, more proportionate way. Our politics must again put the long-term interests of our country before the short-term political needs of the moment."
The Prime Minister confirmed that he had planned a speech in which he is expected to point out the UK is already a world leader in cutting emissions and argue that further changes must be 'realistic and pragmatic'.

A Cabinet source said reports claiming Mr Sunak was committed to the 2030 deadline were wrong:
"Someone was trying to bounce him into sticking to the date, but it hasn't worked. Rishi is committed to net zero but he has always thought you have to take people with you and move in a way that is realistic and pragmatic. We are already one of the world leaders in cutting emissions - it makes no sense to impose more costs on ourselves unless others are willing to help take up the burden."
Delays or changes to seven net zero commitments could be announced in the speech, the BBC reported last night.

Changing the diesel and petrol ban would bring the UK into line with the EU, which has set 2035 as its deadline. Plans to ban the installation of new gas boilers by 2035 could be relaxed, with only 80 per cent required to be phased out by then.

Homeowners may be told there will be no new energy efficiency regulations on their properties. Ministers had considered imposing fines on landlords for failing to upgrade their properties to be more energy efficient. A ban on new oil boilers will also be delayed from 2026 to 2035, with a target for only 80 per cent to be phased out at that date.

Mr Sunak could also announce there will be no new levies to discourage flying, no government policies to make people change their diets, and no measures to encourage car sharing.

The Prime Minister is also likely to scrap plans for a recycling strategy under which homeowners would have had seven different bins.

Conservative former business secretary Sir Jacob Rees-Mogg endorsed the likely proposals, saying: "Taking burdens off the backs off taxpayers during an inflationary period is the right thing to do, and could prove an election-winning strategy."

Fellow Tory MP Craig Mackinlay, chairman of the Net Zero Scrutiny Group, added: "If reports of a delay to the rollout of unrealistic net zero measures are to be believed this is great news for UK consumers. It will make pie-in-the-sky deadlines into ones that are less invasive, less costly and more realistic. I'm pleased to see sensible pragmatism from the PM."

But former Cabinet minister Simon Clarke said: "I am very clear: The delivery of net zero should not be a hair-shirt exercise. But I am equally clear that it is in our environmental, economic, moral and - yes - political interests as Conservatives to make sure we lead on this issue rather than disown it."

And Tory MP Chris Skidmore, a former energy minister who carried out a review into net zero, said Mr Sunak "risked the greatest mistake of his premiership. If this is true, the decision will cost the UK jobs, inward investment, and future economic growth that could have been ours by committing to the industries of the future."

Speaking to Newsnight, Mr Skidmore called the move:
"Potentially the greatest mistake of his premiership so far. I've seen on the WhatsApp groups, many MPs very concerned about the messaging. And it runs against the commitment we've made in our general election manifesto in 2019. Support net zero.

"The key thing here, you can't just say that you're back in net zero by 2050 and that you're going to tweak the targets in the middle. Those targets are essential to meet the pathway, and net zero isn't about 2050, it's about meeting our commitment we make it to the 2030 because if we don't make our 2030 targets, we are not ever going to be on track for 2050."
He urged the PM to 'think again' and said there would be 'serious consequences' for the economy, growth, jobs and investment if net zero commitments aren't adhered to.

In a statement sent to Newsnight, Lord Goldsmith said Rishi Sunak was 'dismantling credibility' by backtracking on government's net zero plans, and that this would be looked back on as a 'moment of shame'.

Lord Goldsmith said:
"Around the world, one of the few areas where the UK really is looked up to is on climate and the environment. Today Sunak is dismantling that credibility, not by accident but by choice. He is doing so having taken over a Party elected with a big majority on a manifesto that could not have been clearer about our commitment to tackle climate change and provide global environmental leadership.

"And after having solemnly pledged to his own MPs that he would honour those Manifesto commitments. His short stint as PM will be remembered as the moment the UK turned its back on the world and on future generations. A moment of shame."
Hilary McGrady, chief executive of the National Trust, said:
"This would be a deeply depressing step. From flooding to wildfires we're facing the impacts of climate change here and now. We need to step up ambition, not water it down."
Mr Sunak has been under pressure from the Right of his party to cut back on costly green policies in order to win the next election.

In July, the Tories held on to Uxbridge and South Ruislip in a by-election that Labour had been expected to win after an outcry over London Mayor Sadiq Khan's policy of expanding the zone for the Ulez levy on the worst-polluting vehicles.

Mr Sunak is expected to position his Government on the side of motorists frustrated by green policies.

However, any policy reversal would mark a significant shift after the UK hosted the COP climate summit in Glasgow two years ago.

Since then, Mr Sunak has approved the licensing of more drilling for oil and gas in the North Sea.

He will not attend a UN General Assembly meeting in New York this week, where nations are due to set out sustainable development goals. He will also not accompany the King on his state visit to France, where he will host a forum tomorrow to urge action on emissions.

Government sources did not deny that any of the commitments were under review but insisted the 2050 net zero commitment would stand.

A spokesman said last night:
"The Government remains completely committed to its net zero commitments, with the UK having cut emissions faster than any other G7 country. Our approach will always be pragmatic and ensure costs are not passed on to hard-working families. We will not comment on speculation."
