What should the public believe when it comes to net zero?

Ministers are being urged to confront the growing wave of misinformation that is distorting public debate about climate change and the push to reach net zero, after a new cross-party report from the Commons Energy Security and Net Zero Committee warned that the UK’s transition to a clean energy economy is at risk. The committee says false claims about climate science and the energy transition are spreading rapidly through social media, with artificial intelligence tools now making it easier than ever for inaccurate information to be generated, amplified and accepted as fact. In its findings, the committee insists that the public’s support must be won through honest, clear and consistent communication; otherwise, the UK will not be able to deliver the policies needed to meet its legally binding climate targets. The report expresses particular concern about the way online ‘experts’ and AI-generated content have blurred the line between evidence and opinion, allowing misinformation to take root in large parts of the national conversation. It also criticises official messaging as inconsistent, overly technical and disconnected from everyday life. The committee calls on the government, regulators, social media platforms and civil society to work together to challenge false claims and to explain the benefits of the energy transition in simple, tangible terms. The committee, made up of MPs from all major parties, conducted hearings and reviewed evidence from scientists, campaigners and industry leaders. It concluded that the national conversation about climate change is being distorted by an often toxic information environment. The report warns that this is not a side issue: public support is a precondition for the long-term policy programmes required, and once lost it is very difficult to regain. With the government now having two months to respond, the report is one of the strongest signals yet that the battle over climate policy will be decided as much by public perception as by emissions statistics.

The report points to specific public figures whose statements have been shown to be inconsistent with established climate science. Richard Tice, deputy leader of Reform UK, is quoted as saying that ‘net zero will make zero difference to climate change’. Brian Catt, a retired British physicist, is quoted as saying that ‘carbon dioxide has no provable effect on the climate’. The committee says both claims have been proven scientifically wrong, but that the misinformation has not been widely flagged and may still be believed by people who encounter it on social media. It argues that these are not harmless comments; they help build a narrative that net zero is a pointless and damaging project imposed on the public by remote elites. That narrative, in turn, can undermine public support for clean energy projects, home insulation schemes, electric vehicle targets and other policies that are essential to the transition. The report draws a distinction between honest scepticism and the deliberate or reckless spread of false claims. It acknowledges that not everyone who shares misinformation is acting in bad faith, but says the effect is the same: confusion, cynicism and a sense that there is no point in trying. By the time official corrections are published, the claims have already been seen by millions. The committee also warns about the rise of AI-generated content, which can produce realistic articles, videos and social media posts at scale, often mixing true facts with invented claims. Regulators, platforms and politicians all have a duty to respond with the same speed and repetition as those spreading falsehoods. Misinformation, the report makes clear, is not merely a nuisance but a strategic threat to the delivery of the UK’s climate commitments.

At the heart of the problem, the committee argues, is a failure of communication. ‘Current messaging from the whole of public society is inconsistent, overly technical, and does not sufficiently connect the energy transition with tangible, everyday benefits such as lower bills, warmer homes, jobs and career opportunities for young people, energy security and health improvements,’ the report says. The phrase ‘whole of public society’ is a pointed one: the committee is not blaming a single department or a single political party. It is criticising the entire ecosystem of official communication—from ministers and civil servants to local authorities, public bodies, broadcasters and perhaps every institution that speaks about climate policy—for failing to make the case in language ordinary voters can understand. Instead, the public is expected to decipher acronyms such as DESNZ, CCC, interconnectors, carbon budgets, scope three emissions and load shifting. These terms might be precise, but they do not tell a family whether their home will be warmer, whether their bills will be lower, or whether their children will have good local jobs. The committee’s criticism extends to the language used by the government itself. Words like ‘transition’ and ‘decarbonisation’ are used without definition. Targets are announced with headlines but little explanation. The result is that the climate debate often feels like a technical argument between experts rather than a conversation about the future of the country. The report argues that many people have concluded that net zero is about sacrifice and lifestyle restrictions simply because nobody has explained, in plain terms, what it can deliver. The committee says this must change: the energy transition needs to be presented as a practical project for national renewal, not as a distant target on a graph.

Perhaps the most striking recommendation is to retire the term ‘net zero’ itself. ‘The term net zero has become a distraction from the broader aims and benefits of the energy transition,’ the report declares. The committee asks the UK government’s energy department to drop ‘net zero’ from its name, so that the Department for Energy Security and Net Zero would become something more like the Department for Energy Security. This is not just a cosmetic change; it is intended to reframe the entire conversation. In the committee’s view, ‘net zero’ has become a lightning rod. It is associated in the public mind with a single date, 2050, and opponents have used it as shorthand for everything from unreachable targets to high levies, heavy-handed regulation and alleged threats to personal freedom. By keeping it at the centre of the department’s name, the government is allowing the debate to be framed around a slogan. Some campaigners have argued that the government should not surrender a term that has a legal basis and clear meaning. But the committee’s point is precisely that the term has ceased to have a clear meaning for most people. It has been captured and repurposed by opponents, and the government has done little to defend or reclaim it. The committee argues that this obscures the real questions: how to generate cheap clean power, how to insulate homes, how to reduce dependence on imported fossil fuels, how to create jobs in new industries and how to improve public health through cleaner air. A new name would not erase the legal target—the UK remains committed to net zero by 2050 under the Climate Change Act—but it would send a signal that the priority is the energy transition’s benefits, not the destination. The report insists that the energy transition is about the kind of country Britain is building, not just about emissions.

So what should the public actually hear? The committee’s answer is straightforward: less jargon, more real-world benefits. People need to understand what the energy transition means for their own lives: lower bills, warmer homes, secure energy, cleaner air, skilled jobs and career opportunities for young people. If these benefits are not made visible, the report warns, the political space for climate action will continue to shrink. The committee calls for a new national communications strategy, using simple and consistent messages, repeated by trusted voices including local leaders, community groups, businesses and trade unions, not only by central government. It wants the government to work with media outlets and social media platforms to ensure accurate information is at least as easy to find as false information. It also says the benefits of the transition must be demonstrated in practice—through visible projects such as home insulation programmes, renewable energy developments, public transport investment and green industrial hubs—so that people can see and feel the change. The committee also says that the benefits should be felt fairly across the country. If some communities are asked to host wind farms or grid infrastructure while others see no improvement in services or jobs, the resentment that this creates can be exploited and can erode support for the wider programme. The report acknowledges that the transition is difficult: costs are often immediate, while benefits take years to arrive, and there will be debates about specific technologies and planning decisions. But the alternative is worse: if people believe that net zero is a fantasy or a conspiracy, they will reject the policies that are essential for the country’s future. The committee’s message is that the public deserve better than a debate built on slogans and misinformation.

The government now has two months to respond formally to the report. Select committee reports are not binding, but they carry considerable political weight, and a dismissive response would risk turning climate communication into a major political conflict. The report will put pressure on the Department for Energy Security and Net Zero to reconsider not only its name but its entire approach to public engagement. It may also reignite disagreements within government about the speed and cost of the transition, and about how to talk about climate change without either frightening the public or fuelling the culture war that has come to surround the issue. Reaction to the committee’s findings is likely to be divided. Environmental and industry groups, which have long complained that the UK’s net zero debate is dominated by misinformation and negative headlines, will welcome the intervention. Some critics, however, may argue that dropping the term ‘net zero’ would be an unnecessary concession to those who have weaponised the phrase, and that changing a department’s name will not stop false claims from circulating online. The committee’s answer is that words matter: language frames public debate, and changing the terms of the argument is an essential first step. Some of the report’s recommendations may be easier to accept than others, but taken together they form a powerful critique of the way climate policy has been communicated. The government will need to decide whether to embrace that critique or defend its existing approach. As the response deadline approaches, the wider public will also be watching to see whether the message from ministers changes. More broadly, the report is a reminder that the greatest threat to Britain’s climate goals may be political rather than technical. A transition that is poorly understood and weakly supported can be delayed or reversed at the ballot box. The committee argues that the public needs honest, clear and consistent information—not because they cannot handle complexity, but because they are entitled to know what is being done in their name and why.
