Switzerland's bold plan: Tax flights to fund greener public transport

A new climate policy initiative in Switzerland is pushing for a tax on flights to fund better public transport. The plan, backed by environmental groups, would also give residents travel vouchers worth around CHF 110 each. Organisers now need to gather 100,000 signatures within 18 months to force a national vote.

The proposed flight tax would apply to all plane tickets departing from Switzerland. Short-haul flights within Europe would face a minimum levy of CHF 30, while long-haul routes would cost at least CHF 120. Private jets would be taxed even higher, at CHF 500 per flight.

The money raised—an estimated CHF 1.5 billion—would go toward expanding international rail connections and improving domestic public transport. Swiss residents would receive vouchers for trains and buses, which could also be used to buy a half-fare travelcard or given to others.

The initiative has gained wide public support, but some center-right parties remain sceptical. If the petition succeeds, the proposal will move to a federal vote, deciding whether Switzerland adopts the new climate-friendly transport policy.

The campaign must collect 100,000 signatures in the next 18 months to trigger a referendum. If approved, the flight tax would fund transport upgrades and provide residents with travel vouchers. The outcome could reshape how Switzerland balances air travel with climate goals.
