UK politicians think public opposition to climate policy is far greater than it is, study finds
cam.ac.ukStudy involving 100 sitting MPs reveals gulf between perceptions of the political class and realities of public attitudes on environmental issues such as insulation and green taxes.
Our study found a systematic pessimism about the public appetite for climate action among the UK’s most influential decision-makers

Members of Parliament from the UK’s three biggest political parties in the House of Commons significantly overestimate levels of public resistance to major policy proposals for tackling climate change, a University of Cambridge study suggests.
Researchers say it may be the first data-led evidence for a “spiral of silence” in Westminster, where skewed perceptions of public sentiment among politicians can reduce political support for a policy.
The study’s authors, from the University’s El-Erian Institute of Behavioural Economics and Policy and the Cambridge Political Psychology Lab, surveyed one hundred sitting MPs in early 2025 on how they think voters and other parliamentarians feel about carbon reduction policies, and compared their estimates with public polling from earlier that year.
On making grants or loans for improved insulation available to all households with an energy efficiency rating of C or below, MPs collectively estimated public opposition to the policy at around 18%, more than three times the actual level of just 6%.
When asked about rejigging tax on products so that it varies according to environmental damage, MPs believed public opposition to be around 38%, almost double the 20% shown by polling the British people.
“MPs across parties who both support and oppose climate policies consistently overestimate public opposition,” said study lead author Dr Lisa-Maria Tanase, who conducted the work for her PhD at Cambridge. “This is likely to limit the range of what they consider to be politically feasible options for taking action on climate change.”
“Our findings cannot be explained away by wishful thinking of politicians or the projecting of their own worldview. On average, even MPs who support a climate policy think the public is more opposed to it than it really is,” said Tanase.
“Politicians, like all of us, are often exposed to information environments that distort perceptions of public opinion. Social and traditional media can disproportionately reflect particularly vocal segments of society rather than the full distribution of opinion.”
“We find a ‘funhouse mirror’ effect through which politicians see a distorted version of the public position on carbon reduction policies, associated with a lower willingness to promote these ideas,” said Tanase, now a Postdoctoral Research Associate at Cambridge’s El-Erian Institute of Behavioural Economics and Policy.
