Progress of UK towards 2050 net zero climate target

When former Conservative Prime Minister Theresa May enshrined the UK’s 2050 net zero goal into law in 2019, it received cross-party support in parliament. However, that political consensus has since fragmented as critics frequently use the term "net zero" to challenge environmental targets they claim are prioritised over economic objectives.

Labour Prime Minister Andy Burnham has stated he remains "determined" to reach the 2050 deadline, a policy also supported by the Liberal Democrats. In contrast, the Green Party advocates for achieving net zero "as soon as possible, and more than a decade ahead of 2050". These parties contend that transitioning away from fossil fuels, which can be volatile in price and subject to supply interruptions from international events like the US-Israel war on Iran, is in the nation's economic interest.

Conversely, the Conservatives and Reform UK have called for the UK's net zero target to be scrapped, describing current plans as expensive and unachievable. They argue that the UK's efforts have minimal impact on climate change when considered in isolation, particularly because national emissions are significantly lower than those of the US and China.

Devolved administrations have set their own timelines, with the SNP aiming for net zero in Scotland by 2045. Meanwhile, Plaid Cymru has proposed a deadline of 2040 for Wales.
