Tackling greenhouse gas emissions is bottom of the list of priorities for Tory voters who will choose the next Prime Minister, a new poll shows.
Just 4% of Conservative members put the hitting "net zero" by 2050 was in their top three priorities for their next party chief, who will succeed Boris Johnson in September.
The YouGov survey for the Times found 56% of those surveyed said that winning the next election was the most important issue.
Tory members prioritised controlling immigration next and battling the cost of living crisis, with hitting net zero at the bottom of a list of ten policy areas.
The climate commitment fell behind cutting personal taxes, increasing defence spending and strengthening Britain’s global standing in the poll.
It comes as Brits brace for the hottest day on record, with temperatures expected to spiral as high as 41C.
The Met Office issued a red alert warning of extreme heat from Monday to Wednesday in much of England.
Met Office chief executive Professor Penelope Endersby told BBC Radio 4's Today Programme: "These temperatures are unattainable in the UK without climate change, they just don't appear in the ensembles at all.
"They're still rare in today's 1.1 - 1.2-degree warmed climate, but by 2100, we're expecting them to be anywhere between one in 15 and one in three years, depending on the emissions pathways we take between now and then."
It comes as Tory climate chief Alok Sharma threatened to resign if key climate pledges were watered down.
The COP26 President did not rule out resigning in an interview with the Observer, as fears mounted that top Tories were keen to distance themselves from climate commitments.
Asked if he could resign if candidates were weak on net zero, Mr Sharma said: "Let's see, shall we? I think we need to see where the candidates are. And we need to see who actually ends up in No 10.
"I hope every candidate realises why this is so important for voters generally and why it's important for Conservative supporters. And I hope that we will see, particularly with the final two, a very clear statement that this is an agenda that they do support."
Pressed a second time, he added: "I don't rule anything out and I don't rule anything in."
All the candidates except Kemi Badenoch support the goal of Net Zero emissions by 2050, but several have dropped policies that would help achieve it, with Liz Truss pledging a pause on green levies on energy bills.
