Tracker data: Do MPs see Net Zero as a vote winner or loser in Red and Blue Wall seats?

The Conservative Party suffered their ‘worst ever’ result at the 2024 General Election. As well as general dissatisfaction with the Conservative government, polls consistently showed that worries about the cost of living, the condition of the NHS (and for some, immigration) were the biggest influences on how people voted.

Climate change – and more broadly environmental problems like air pollution and sewage in rivers – were also cited by voters when asked to select their top three most important issues going into the election. But was climate change a ‘vote winner’ at the election?

Echoing previous research showing an appetite for greater leadership on climate change, a large (20,000 people) survey by Focal Data on behalf of Persuasion and ECIU found that 53% of voters who had switched their vote from Conservatives to Labour (or the Liberal Democrats) believed that Government policy on climate change should be going further and faster that it has been (27% thought it should be going more slowly).

And polling by More in Common on behalf of E3G went even further, showing that Rishi Sunak’s decision (in September 2023) to slow down some of the country’s net zero policy timelines had a negative impact on voters. People were twice as likely to say that delaying net zero targets was one of Sunak’s biggest mistakes, than his biggest achievements.

Whilst the General Election was not fought on climate and net zero grounds (compared with the last General Election in 2019, there were roughly 50% fewer mentions of ‘climate’ in the British media election coverage), these findings suggest that there is currently no political capital to be found in opposing green policies.

The only party standing on an anti-net zero ticket were Reform UK – but the same More in Common polling found that immigration was overwhelmingly the reason that people voted for this party. Only 4% selected Reform’s environmental policies as a reason for voting for them.

Polling by Opinium for the Conservative Environment Network (CEN), conducted just before the 2024 General Election was announced, suggests that playing into Reform UK’s anti-net zero stance will not be a vote winner for the Conservative party.

One important finding is that although Reform UK is (uniquely among the other mainstream parties) campaigning on an anti-net zero ticket, climate change is not currently a salient issue for Reform voters. The CEN polling found that only 2% of Reform voters listed climate change/net zero/environment as their primary concern (the majority chose immigration as their primary concern).

This mirrors polling carried out across multiple European countries, ahead of the EU election which saw significant gains for far-right parties. In Europe, as in the UK, the rise in support for right wing parties does not appear to be driven by these parties’ policies on climate change (even if they tend to hold anti-net zero positions).
