Car Deregistration Incentive with Mobility Credits

Offer residents a financial incentive to permanently deregister a car, paid as credits redeemable for public transit passes, bike-sharing, car-sharing, and cargo bike rentals rather than cash. This ensures the incentive shifts behavior rather than just subsidizing a transaction. Basel's Umweltprämie (CHF 1,500, launched September 2025, 400 slots) is a working pilot of this approach. Helsinki's mobility-as-a-service platform demonstrates the broader ecosystem needed to make car-free living genuinely convenient.
