Should advertising be responsible for what we consume?

Advertising is pretty good at making us want things, whether that’s a new pair of trainers, a weekend away, another jacket that looks suspiciously similar to the five already hanging in our wardrobe.

It's sort of the point.

But what happens when encouraging people to buy more clashes with efforts to protect the environment?

In September 2026, Bristol City Council introduced restrictions on advertising for certain high-carbon products and services in council-controlled spaces. Flights, SUVs and some ultra-fast-fashion promotions are among the categories affected.

It's an interesting move because it asks a question marketers don't always love answering: should we be thinking about the consequences of the purchases our campaigns encourage?

What has Bristol actually restricted?

First, Bristol hasn't banned fast-fashion advertising, car adverts or holiday promotions across the entire city.

Its policy applies to advertising spaces controlled by the council, including relevant billboards, bus shelters and digital displays. It doesn't automatically cover privately owned advertising sites.

The updated policy took effect on 23 September 2026. It restricts promotions for categories including fossil fuels, flights, cruises and certain vehicles, alongside advertising that encourages excessive fashion consumption.

The fashion element is particularly notable. Bristol has been described as the first UK council to specifically restrict ultra-fast-fashion advertising, including promotions built around flash sales, Black Friday and pressure to buy quickly.

To be clear, the policy isn't a blanket ban on clothing adverts; it's partly about the techniques used to encourage frequent, often impulsive purchases.

In other words, the council isn't only asking what is being advertised, it's also asking how.

Why is advertising part of the climate conversation?

When we talk about reducing environmental harm, we tend to focus on manufacturing, packaging, transport and waste. But is there more to the conversation? 

Advertising doesn't physically produce another jacket or put another plane in the sky. But it can influence demand for both, the human brain is very susceptible to these advertising techniques. 

A well-placed advert can introduce a product, make it desirable and create a sense that buying it now is a very good idea. Sometimes that's genuinely useful. Other times, it's persuading us to buy something we hadn't given a second thought to five minutes earlier.

Campaigners such as Adfree Cities argue that public authorities shouldn't promote high-carbon consumption while pursuing environmental goals.

There's a logic to that. If a council is trying to reduce emissions, why should its advertising estate encourage activities associated with higher emissions?

But the debate isn't quite that simple.

Is advertising really the problem?

Advertising is one influence on what people buy, but not the only one.

People fly to see family, replace broken cars and buy clothes because they need them. Restricting adverts won't remove those needs, or solve the environmental problems involved in producing and delivering the products.

There's also a fair question about effectiveness. If a brand can't advertise on a council-controlled billboard, could it simply move its budget to a privately owned site or social media?

Supporters would point out that public advertising space isn't an automatic right. Councils already make decisions about what they're prepared to promote, and climate-related restrictions are another expression of those priorities.

I think both arguments deserve consideration. We shouldn't pretend an advertising policy can fix overconsumption on its own. Equally, we can't claim marketing has no influence over consumer behaviour when influencing consumer behaviour is a fairly substantial part of the job.

The interesting question is how much responsibility comes with that influence.

Fast fashion makes this particularly interesting

Of all Bristol's restrictions, the focus on ultra-fast fashion is the one that caught my attention. Not just because of the environmental debate, but because it puts familiar marketing tactics under the microscope.

Flash sales. Countdown timers. Limited-time offers. Black Friday messaging that makes it feel as though the world might end if you don't order those trousers by midnight.

These tactics are everywhere, and there's a reason businesses use them: urgency can help drive sales. But there's a difference between letting customers know about a genuine offer and creating pressure to buy things they don't need.

That's what makes Bristol's approach interesting. It brings the method of persuasion into the conversation, not just the product being sold. Of course, a discount isn't inherently irresponsible. Smaller retailers use promotions to manage stock, attract customers and keep their businesses going.

The question is whether a campaign helps people make a decision or pushes them towards constant consumption for its own sake.

That's a distinction worth thinking about, regardless of whether your business is affected by the policy.

Could other councils follow?

Bristol isn't the first UK council to restrict advertising for certain high-carbon products. Other local authorities, including Edinburgh and Sheffield, have adopted related policies.

Its specific approach to ultra-fast fashion is what makes this decision stand out.

If more councils introduce similar rules, advertisers may need to pay closer attention to who owns the spaces they're booking and what each local policy permits. An outdoor campaign accepted in one location might not be allowed in another.

That doesn't mean a nationwide ban is around the corner. Local policies vary, and their effectiveness will need to be assessed over time.

But it does suggest that environmental considerations are becoming part of media planning, not just the sustainability page on a company's website.

What should smaller businesses take from this?

Most small businesses won't be directly affected by Bristol's decision. Your local café or B2B consultancy probably isn't booking a billboard to promote long-haul flights.

Still, the wider question is relevant: what behaviour does your marketing encourage?

There's nothing wrong with wanting to sell more. Businesses need revenue, and good marketing should support that. But it's worth looking at whether every message relies on urgency, scarcity or another reason to buy immediately.

Could you explain why a product is useful, how long it lasts or who it's right for instead? Could you make the case for quality or service without suggesting customers need five of everything?

And if your business has genuine environmental benefits, talk about them clearly. Just make sure you can back up what you say. The Advertising Standards Authority requires environmental claims to be accurate and supported by evidence; vague promises about being “green” aren't a substitute for specifics.

Thoughtful marketing doesn't have to be timid marketing. It just means considering what you're asking people to do, and why.

So, should advertising be responsible?

I don't think the answer is that advertising should stop selling. Nor do I think restrictions on their own will solve the environmental impact of overconsumption.

But Bristol's decision challenges the idea that marketers can focus entirely on generating demand without considering what that demand means.

And perhaps that's a useful challenge.

We spend a lot of time asking how to make people buy. It might be worth occasionally asking whether we're giving them a good reason to.
