Geopolitical tensions in the Middle East and the ongoing climate crisis have reignited a debate over the apply of Swiss roads. Martine Docourt, an SP National Councilor from Neuchâtel, has submitted a motion during the spring session calling for the creation of legal foundations for car-free days.
A Legislative Push for Fossil-Free Mobility
The motion seeks to allow cantons to easily reserve specific roads exclusively for pedestrians, cyclists, hikers, and inline skaters. Docourt argues that promoting mobility without fossil fuels is essential in the face of climate change.
While the proposal aims for a broader legal framework, the Federal Council has previously described the idea as “sympathetic.” However, the government has identified significant hurdles, including the need for exceptions for emergency services (Blaulichtorganisationen).
Regional Successes and Local Resistance
Some regions have already implemented car-free concepts on a smaller scale. In Graubünden, the “Freipass Graubünden” initiative, organized by Pro Velo Graubünden and tourism organizations since 2024, bans cars and motorcycles from five passes for one day each.
These passes include the Flüela, Lukmanier, Splügen, Stilfserjoch/Umbrail, and Albula. The popularity of these events is evident; last year, 3,000 people visited the Lukmanier pass and 7,000 visited the Splügen pass during their car-free days.
Other local examples include the Klausenpass, which remains car-free on September 13, and the road to Klöntal in Glarus. Following a Landsgemeinde decision, Klöntal observes a motor vehicle ban on June 28, July 26, and August 30.
However, support is not universal. The Neuchâtel cantonal parliament rejected the introduction of car-free Sundays at the cantonal level in January.
Obstacles to National Implementation
The Federal Council suggests that regional “Slow-up” days are a more suitable format for promoting climate-friendly mobility than national mandates. This cautious approach aligns with historical public sentiment.
In 2003, Swiss voters clearly rejected a popular initiative that would have established one car-free Sunday per season. Any move toward a national legal framework could face similar political resistance.
Future Outlook
Depending on the Federal Council’s response to the motion, the legal process for cantonal road reservations could be simplified. This may lead to an increase in regional car-free events, provided that emergency service access can be guaranteed.
