May elections 2026: Where do the parties stand on climate?

With elections round the corner, we wanted to bring you a run-down of where the parties stand on climate. Local elections in England, plus elections to the devolved parliaments in Wales and Scotland, take place on Thursday 7 May 2026.

Make sure you’re registered to vote! Take a look at our register to vote page for guidance on how to do it.

How to VoteClimate in May’s elections

Local elections: Based on the parties’ policies and records in office, we recommend voting Green where they are standing and have a chance of winning. Liberal Democrat is the next-best option. We do not recommend a vote for Labour.

Devolved elections:

  • Wales: We recommend voting Green under the new proportional system.

  • Scotland: For your constituency, we recommend voting for the Scottish Greens where they are standing, and Lib Dem as the next-best option. For your region, which uses a proportional system, you can always vote for the Scottish Greens.

Please note: Our ‘at a glance’ summaries are not comprehensive lists of policy pledges. However, we’ve included all policy developments since the 2024 general election. For a full list of 2024 manifesto pledges, please see our individual party manifesto analyses, linked under each party.

🔴 Labour

At the last general election, Labour's manifesto commitments ranked third by emissions reductions, after the Greens and the Lib Dems. Read our assessment of Labour’s 2024 manifesto.

As the governing party, we can now assess Labour's record in office so far. We reviewed the Labour government’s first year in office back in July 2025. One year in, we found that they had made progress on 15 of their 25 environmental pledges, had made no progress on six and had backtracked on four. There have been some developments since then.

VoteClimate assessment: Labour's policies are woefully inadequate in delivering the emissions reductions needed to keep the UK within its share of the global carbon budget needed to limit warming to 1.5°C above pre-industrial levels. On paper, however, their manifesto pledges were relatively strong compared with other parties. But since entering office, Labour has weakened and reversed course on some of its commitments. This election is a chance to hold Labour's feet to the fire to honour and exceed its manifesto commitments on climate. We DO NOT recommend voting Labour in 2026 in Wales or Scotland, or in English local elections where Greens or Lib Dems are standing.

🔵 Conservatives

We rated the Conservatives worst of the three main parties for climate action in 2024 general, with no positive green policies to speak of, with the exception of a single retrofitting policy which they had already introduced while in government. Read our assessment of the Conservatives’ 2024 manifesto.

Under Kemi Badenoch's leadership, the Conservatives have shifted dramatically away from their previous support for climate action. They have pledged to ditch the statutory net zero requirement they themselves introduced to Parliament in 2019 under Theresa May's leadership, as well as to repeal the groundbreaking Climate Change Act.

VoteClimate assessment: Despite performing relatively well on climate for a few years between 2019–22, the Tories have backtracked into a Reform-like climate-sceptic stance, ditching net zero and pledging to ramp up oil and gas production. We DO NOT recommend voting Conservative in 2026.

🟡 Liberal Democrats

We ranked the Lib Dems second in terms of climate pledges in the 2024 general election. Read our assessment of their 2024 manifesto. Their policies were not great, taking us through our share of the global carbon budget needed to keep temperature rises to 1.5C by 2034 (the same as Labour).

In September 2025, Lib Dem members voted through a new set of climate policies at the party's conference, improving their policy programme. These included closer working with the EU to tackle climate change, a National Climate Assembly to involve citizens in decision-making and a zero carbon standard for all new buildings.

VoteClimate assessment: The Lib Dems were ahead of Labour in our assessment of the parties' 2024 local manifestos, with their policy programme producing more emissions reductions over time (although Labour's policies produced greater reductions up to 2030). Since the election, the Lib Dems have improved their climate offer with their 2025 package of policies. We recommend a vote for the Lib Dems, where Greens are unlikely to win in local elections in 2026.

🔵 Reform UK

You may not be unsurprised to learn that Reform UK did abysmally in our assessment of the parties' 2024 commitments on climate. Party leader Nigel Farage presents himself as a climate denier, claiming that climate change is mainly driven by natural factors, and the party would scrap net zero and any policies designed to reduce emissions. Read our assessment of Reform UK’s 2024 manifesto.

Given they started from a very low bar, very little has changed since the 2024 elections, except perhaps the rhetoric of Reform politicians. Reform is supported by climate-sceptic think tanks and funded by wealthy donors with interests in the fossil fuel industry. Unfortunately, they are polling very well, likely due to other factors as there is no widespread climate scepticism among the voting public.

VoteClimate assessment: Reform's policies would trash the planet. By doing away with net zero, ending support for renewables and ramping up oil and gas production, their programme would see emissions skyrocket. We strongly advise against voting Reform in any seat.

🟢 Green Party (England and Wales)

Unsurprisingly, we ranked the Green Party top on climate in the 2024 general election. Their policies are far and away the best when it comes to tackling climate change – although the Greens' 2024 policies still took the UK through its share of the global carbon budget around 2038. Read our assessment of the Greens’ 2024 manifesto.

Since the election, the Greens have elected a new leader, Zack Polanski, and adopted a more eco-populist approach to campaigning — connecting the climate emergency to other bread-and-butter issues such as cost of living. Polling and the recent Gorton and Denton by-election suggest this is popular with voters. However, their climate agenda has not dramatically changed.

VoteClimate assessment: The Green Party are streets ahead of the other parties on climate — although even the Greens' policies do not go far enough. In our comparison of parties' 2024 manifesto pledges, the Greens exceeded the UK's portion of the global carbon budget five years after the other parties. Their policies have not evolved dramatically since 2024 — the main shift has been in their rhetoric. However, they are still the best vote for climate by a long shot, and we recommend a vote for the Greens wherever they stand a chance of winning.

Devolved parliaments

The following sections cover parties operating through the Scottish Parliament and the Senedd in Wales. Climate policies are largely down to devolved administrations, although UK-wide policies have an effect on emissions.

🏴 Scotland: SNP

The SNP has been the governing party in Scotland, either as a majority government or in coalition, since 2007. So we can look at their record in office as well as their policy positions.

VoteClimate assessment: Although the SNP has made some positive commitments on climate, it is reversing course on many of these, including the 2030 milestone on Scotland's journey to net zero, which signals a slowing of progress. The weakening of the SNP position on new oil and gas is also concerning. The Climate Change Commission’s criticism of the SNP government's draft net zero strategy shows that its policies are not in line with its rhetoric.

🏴 Scotland: Scottish Greens

The Scottish Greens have a track record in government, having ruled in coalition with the SNP between 2021 and 2024. The alliance ended when SNP first minister Humza Yousaf dropped the 2030 target to reduce emissions by 75%, which the Greens had secured as part of their coalition agreement. The Scottish Greens’ successes also included a £65 million Nature Restoration Fund and free bus travel for under 22s, which they propose to expand in government.

VoteClimate assessment: The Scottish Greens have some ambitious climate pledges and pushed the SNP into more radical green policies during the short-lived coalition government of 2021-24. They put their money where their mouth is by ending the coalition when the SNP backtracked on the emissions targets which formed part of the coalition agreement.

🏴 Wales: Plaid Cymru

In 2026, the Welsh voting system is moving from a mix of proportional representation and first past the post to a fully proportional system. Find out more about the new system in our explainer.

VoteClimate assessment: While Plaid Cymru talks a good game on climate — with a reasonably ambitious net zero deadline and a strong position on oil and gas — the party has announced very few concrete policies to achieve its goals. It seems noteworthy that Plaid has backtracked on its 2035 net zero target when faced with the prospect of entering government as the party polls well ahead of the 2026 Senedd elections.
