I will come on to some of those arguments, but I recognise what the hon. Lady says. It is important to note that fossil fuel companies will be key to the transition. Many are, in fact, investing heavily in renewable energy, alternative fuels and low-carbon technologies.
The Advertising Standards Authority, which I met ahead of the debate, made it clear that it has no official position on a ban and that it is for Parliament to decide. It is cautious about stepping into territory where it might be seen to regulate brand image rather than specific advertising claims. Frankly, it has a point, because there is a fine line between stopping misleading adverts and telling a company that it cannot speak at all. The ASA also noted that when companies are genuinely diversifying—investing in wind, solar and hydrogen—they should be allowed to share that progress; otherwise, how do we know if they are making any?
Then there is the issue of capacity. As Badvertising and others have noted, the ASA is already stretched. It often takes months to investigate ads, by which time the advert in question has already run its course, its messages have been absorbed and its impressions have been made, so we are left with a reactive system chasing after a rapidly moving industry. Some critics make the slippery slope argument: “If we ban fossil fuel ads, will cars be next? What about flights, steaks and leather shoes? Where do we draw the line before we are banning Sunday roasts and petrol lawnmowers?”
Let me be clear that those are not trivial objections—they speak to the real tensions between climate emergency, free enterprise and democratic openness—but now I want to turn to the other side of the debate. While all speech may be free, speech is not without consequence, and fossil fuel advertising is not just a matter of a few billboards here and there; it is increasingly a co-ordinated strategy to build trust, shape culture and delay structural change. Groups such as Badvertising and the New Weather Institute have made that clear in both their research and their rhetoric.
As was revealed by internal BP advertising memos, fossil fuel companies seek to reinforce their social licence and influence consumer behaviour by associating themselves with progress, positivity and public good. The issue is not just what they say, but where and how they say it. A 2022 report by DeSmog revealed that over 240 fossil fuel campaigns ran across the Transport for London network in six years. Fossil fuel ads appear in Westminster station, for example, not because consumers need urgent advice about offshore drilling, but because that is where we, the policymakers, walk.
We must also talk about greenwashing, which is no longer just a fringe concern; it is now central to the conversation about advertising ethics and consumer trust. Yes, the ASA has taken action—in 2023, it banned Shell, Repsol and Petronas ads that were misleading in their environmental claims, chiefly by omitting the fact that their business remains overwhelmingly dependent on fossil fuel production—but companies are evolving. In 2025, Shell released a new advert that on the surface was still greenwashing, but this time included qualifying language in the small print about its continuing investments in oil and gas and, as a result, technically met the rules. We are in an era of compliant deception: an ad can be accurate but also misleading. A message can be truthful in parts but dishonest in tone. It is a bit like a politician claiming that they never technically lied but conveniently forgetting that they answered a different question altogether—I am not naming any names.
Beyond formal adverts, we must confront the world of sponsorship, where the relationship is less about information and more about association. Fossil fuel companies sponsor not just events, but sports, music, festivals, education initiatives and even museum exhibits. Why? Because we do not remember the product; we remember the feeling, and if the logo has an association with the feeling, the brand has woven itself into the cultural fabric of our society.
The New Weather Institute’s “Dirty Money” report found that oil and gas companies are now spending over $5.6 billion across 205 active global sports sponsorships. This is not just a side hustle; it is a strategy. This is where it gets complicated. We had the British grand prix this weekend. That industry is still heavily reliant on fossil fuels, albeit Formula 1 is on track to be net zero by 2030 and some teams, such as McLaren, are already carbon neutral. Are we to say that a fossil fuel company should not sponsor a sport that at present is a big polluter?
There is a key precedent: in 2002, we passed the Tobacco Advertising and Promotion Act to ban tobacco ads and sponsorships, not because cigarettes had changed or become healthier, but because the science had clarified that the social harm was overwhelming.
