A growing number of cities are quietly reshaping the public spaces people move through every day — not with new infrastructure, but by removing something far more subtle: advertising for high-carbon lifestyles. From Italy to the Netherlands, local governments are introducing bans on ads tied to fossil fuels, air travel, and even meat consumption, signaling a broader shift in how climate policy is being applied at the urban level.

This week, Genoa became the second Italian city to approve a ban on fossil fuel advertising in public spaces, following Florence’s earlier move. The decision passed with a clear majority and targets ads promoting products with a high carbon footprint. Supporters argue that advertising is not neutral — it actively shapes behavior and normalizes consumption patterns that conflict with climate goals. By removing these messages from everyday environments like bus stops and train stations, cities aim to align public space with long-term environmental priorities.

Genoa’s move is part of a wider global trend. More than 50 cities, primarily in Europe, have already introduced or are considering restrictions on fossil fuel-related advertising. Some, including municipalities in the Netherlands as well as cities like Stockholm, Edinburgh, and Sydney, have gone further by implementing full bans. The Hague set a precedent in 2024 by becoming the first city to prohibit ads promoting high-carbon services such as cruise travel and aviation. Meanwhile, Spain is exploring a nationwide ban that would extend these restrictions across the entire country, targeting fossil fuels, combustion-engine vehicles, and short-haul flights where rail alternatives exist.

Amsterdam has taken the concept even further. Starting in May, the city will ban advertisements for meat, fossil fuels, and other carbon-intensive products across all publicly accessible advertising spaces, including transit systems and stations. The policy will later expand to include companies with high CO₂ emissions. The decision was passed despite significant pressure from advertising companies, which warned of financial consequences. Local leaders proceeded anyway, emphasizing the contradiction between encouraging sustainable behavior while simultaneously promoting its opposite through advertising.

The rationale behind these policies reflects a consistent theme: public messaging matters. Officials and advocacy groups argue that cities cannot effectively promote climate goals while allowing widespread advertising of activities they are trying to reduce. In Amsterdam, the policy aligns with a broader ambition to shift dietary habits toward a more plant-based future by 2050. Similar measures in other Dutch cities, along with legal backing confirming such bans serve the public interest, have helped build momentum behind these initiatives.

International organizations have also weighed in. Calls to restrict fossil fuel advertising have drawn comparisons to past bans on tobacco promotion. Critics of the fossil fuel industry argue that advertising campaigns have been used to delay climate action and shape public perception, often presenting environmentally harmful practices in a more favorable light. Legal experts and environmental advocates increasingly see advertising restrictions as a necessary tool to limit that influence and accelerate the transition to lower-carbon systems.

Despite growing momentum abroad, countries like Denmark have yet to implement formal restrictions on climate-damaging advertising in public spaces. However, the debate is gaining traction. Supporters of similar measures point to the mismatch between policy goals — such as reducing emissions from transport and food systems — and the continued presence of advertising that promotes high-emission behaviors. Cities like Amsterdam are now being cited as proof that such policies are not only possible but enforceable, even in the face of economic and political resistance.

What is emerging is a new layer of climate policy — one that operates not through taxes or infrastructure, but through the messages people encounter daily. As more cities adopt these measures, public spaces are becoming a battleground not just for mobility or development, but for the narratives that shape consumption itself.
