Following the General Election, there is a clear uptick in support for the country’s net zero targets. Support for net zero by 2050 is at its highest point in almost 2 years, yet enthusiasm for some flagship policies hasn’t yet caught up.
The first Climate Barometer public poll following the General Election shows a clear uptick in support for the country’s net zero targets: support for net zero by 2050 is at its highest point in almost 2 years.
These figures were reported by the Independent, in a story that noted “despite the previous government watering down climate measures, such as bringing in electric cars and banning gas boilers, support for net zero also increased among Conservative voters.”
Strikingly, the rise in support for net zero among Conservative voters was the biggest leap – from 59% of 2019 Tory voters in April to 76% of 2024 Tory voters in July. While this may partly be due to changes in the population who voted Conservative in the July election (in which more right-leaning voters switched to Reform), it isn’t the full story. Both those who voted Conservative in 2019, and those who voted Conservative in 2024 show higher support for net zero now (65% and 76% respectively) than in April.
2024 Labour (85%) and Lib Dem voters (89%) are even more supportive. Only Reform voters reported lower support (44%).
But although 2024 Reform voters may currently be less supportive of net zero goals, those who switched from Conservative to Reform at the General Election did not make their decision on the basis of Reform UK’s net zero policies: only 5% of Conservative-Reform switchers mentioned Reform’s climate and environment policies as a reason for their support of the party.
The uptick is encouraging, and the rise among Conservative voters suggests the public isn’t polarised on the pursuit of net zero. But what sits behind these headline findings on net zero targets? Where is the public on the specifics of the energy transition?
Heat pumps
Reported knowledge about heat pumps continues to be low.
Although some have seen heat pumps in the news (41%), most don’t know what they look like (51%), how they work (65%), or know anyone who has one (71%). Around half have not heard about government subsidies for installing them.
Given this low knowledge base – including about important benefits such as subsidies – the picture in terms of public support is reasonably positive, with support remaining relatively stable and if anything, ticking up over time.
And with such a low baseline of knowledge, better public engagement could make all the difference in terms of conveying their benefits (beyond financial incentives).
Electric vehicles
At first glance, the picture isn’t quite as positive around the phase out of sales of new petrol and diesel vehicles, but the devil’s in the detail.
The figure above shows a rise in opposition to the petrol/diesel phase out over time (with support remaining relatively flat, and the number of people who don’t know what they think declining). But when it comes to EVs, misconceptions abound.
We tested a range of ‘anti-net zero’ narratives and soundbites, and found very few of them currently have any cut through with the public. But there was one exception: 40% of people say they don’t think EVs are more environmentally friendly than cars (when in fact they are).
And this isn’t the only misconception about EVs.
Previous Climate Barometer polling showed that when people are reminded that only new vehicles (not second hand ones) will be phased out after 2030, there was a 9% increase in people saying that the phase out would not affect them at all.
And in the latest polling, support for the phasing out of petrol and diesel cars is higher (+5%), and opposition is lower (-6%) when people were reminded that it is only new vehicle sales which must be zero emissions by 2030 (39% support, 38% oppose), compared to support without the prompt about second-hand vehicles (34% support, 44% oppose), a statistically significant difference.
So as with heat pumps, there’s an obvious gap where much bolder and proactive public engagement could be.
Support for net zero by 2050 is rising, but enthusiasm for some flagship policies hasn’t yet caught up. This is a clear signal that campaigning and public engagement on the practical delivery of net zero is now a priority. Otherwise, misconceptions and in some cases simply a lack of familiarity with net zero policies, become fodder for opponents of green policies.
The government’s newly published Local Power Plan points the country in a direction that the British public support: clean energy that’s transparent, affordable, and delivers real benefits to communities and their local environments.
When we asked about the three most important factors for involving local communities on infrastructure proposals, both the public and MPs were most likely to select “clear, plain language information about the project and its impacts” and “being asked for views early, before decisions are made”. These were followed by “a clear explanation of how views influenced the final decision” for MPs and “independent or trusted organisations running the process” for the public.
When we asked which 3 factors people felt were most important in terms of influencing their support or opposition for local infrastructure projects, they picked: the project’s impact on the local environment, on energy bills and on the local community as the top considerations.
These three priorities are consistently the highest for all groups across age, gender, region, social grade, housing tenure, political support, education level, ethnicity, and whether they live in urban or rural areas; a rare point of alignment between these different subgroups of the public.
Strikingly, what made much less of a difference were people’s views about climate change and net zero.
This doesn’t mean that belief in (or concern about) climate change isn’t a critical foundation on which to build engagement around clean energy in general (this is the core idea behind linking the ‘how and the why’ on net zero, as we argued in our recent message testing work with Public First).
But when it comes to specific clean energy projects, the local impacts and financial considerations loom larger: as the transition becomes ever more place-based, this trend is only likely to accelerate.
Our tracker shows the enduring popularity of policies that also save on household bills (like installing insulation, or incentives to do so).
Although Low Traffic Neighbourhoods (LTNs) get a bad rep, our tracker shows support outweighing opposition and support gently rising over the past three years.
One way to look at levels of policy support across the piece is that they’re really quite stable – but some are not stable in a good way. When it comes to sales of new gas boilers, and the phase out of sales of new petrol and diesel vehicles, opposition started to outpace support around 18 months ago, and this trend has (slowly) continued.
