Zurich Narrowly Rejects Air Travel Advertising Ban

The Zurich City Council narrowly rejected a ban on advertising for air travel. A Green Party motion, which called on the City Council to examine a ban on air travel advertising in public spaces, failed by 61 votes to 57. The vote shows how controversial the question is: Should the state restrict advertising for particularly climate-damaging services?

The debate is not limited to Zurich. Other cities are also examining whether public advertising for air travel, combustion engine cars, or fossil fuels is still appropriate. A global movement against so-called "fossil advertising" is growing. However, no general ban on air travel advertising is currently impending at the federal level in Switzerland.

Zurich narrowly rejects the motion

The vote in the Zurich City Council was extremely close. 57 members voted for the motion, 61 against it. The Green Party argued that advertising helps make air travel appear as a natural part of everyday life. If politics aims to reduce air traffic for climate reasons, it must also address how air travel is advertised.

The bourgeois parties rejected the motion. According to SRF, FDP City Councillor Patrik Brunner spoke of an infringement on economic and advertising freedom. This highlights two differing views: one side sees advertising as a tool that shapes demand. The other considers it part of a free market economy where consumers should decide their own behavior. citeturn0search0

Advertising influences behavior – but how much?

Proponents of a ban do not argue that a single poster triggers a flight. Their thesis is more fundamental: if air travel is constantly and attractively advertised, it can contribute to flying being perceived socially as a normal and straightforward form of travel.

The City of Zurich is already addressing why people continue to fly frequently despite their awareness of climate change. A study commissioned by the city concludes that alongside psychological factors, structural reasons also play a role. These include prices, travel time, comfort, and the availability of alternatives. citeturn1search9

However, it is not yet proven that an advertising ban would reduce air traffic to a significant extent. This is one of the contentious points in the political debate.

Bern shows: Legal questions are complicated

Zurich is not the first Swiss city to address such a ban. In Bern, a motion for a ban on advertising posters for air travel and cars was already submitted in 2023.

The Bern City Council concluded in March 2026 that an explicit ban on advertising for air travel, airlines, and cars could generally be legally possible, provided it is anchored at the appropriate municipal regulatory level. At the same time, it pointed to significant demarcation problems and additional implementation effort. The question of what exactly constitutes advertising for a flight or air travel would be particularly difficult. citeturn1search60turn1search2

This shows: an advertising ban would not simply be a political declaration of intent. It would need precise definition and must operate within the current legal framework. Economic freedom must be considered, as must any public interest in climate protection. SECO generally states that state restrictions on economic freedom must be based on an appropriate legal basis, be in the public interest, and be proportionate. citeturn1search4

Other cities go further

Internationally, examples already exist. In Den Haag, a ban on certain climate-damaging advertising in public spaces has been in effect since early 2025. This includes advertising for air travel, cruises, combustion engine vehicles, and fossil fuels, among others.
