Other funding

The CO2 Act provides for a number of new funding schemes to bring Switzerland closer to its 2050 net-zero target. The funding is focused on the energy and transport sectors. The financial resources for this come either from the general federal budget, the revenue from the CO2 levy or the proceeds raised by auctioning emission allowances in the emissions trading system.

Promotion of renewable energies

Article 34a of the CO2 Act provides for various funding schemes for renewable energies. The financial resources for this come from the revenue generated by the CO2 levy. For some time now, funding has been available for geothermal energy projects. Since 1 January 2025, there is also a new funding scheme for renewable gas production installations. In addition, funding is now available for systems that use solar power for industrial heat.

The SFOE is responsible for implementing these funding measures.

Funding for cross-border passenger rail transport

In accordance with Article 37a of the CO2 Act, a maximum of CHF 10 million per year is to be used to support overnight train services from 1 January 2027 until the end of 2030. The financial resources for this come from the proceeds raised by auctioning emission allowances for aircraft.

The FOT is responsible for implementing these funding measures.

Funding for measures to reduce greenhouse gas emissions in aviation

In accordance with Article 37a of the CO2 Act, a part of the proceeds raised by auctioning emission allowances for aircraft will be used to develop and manufacture renewable synthetic aviation fuels. Article 103b of the Aviation Act also guarantees funding for fuels of this kind through additional resources from the federal budget.

The FOCA is responsible for implementing these funding measures.

Funding for electric drive technologies

In accordance with Article 41a of the CO2 Act, the federal government will support the procurement of electric road vehicles and the procurement and retrofitting of electric ships for public transport with a maximum of CHF 40 million per year until 2030. The financial resources for this come from the general federal budget and are partly co-financed by the mineral oil tax.

The FOT is responsible for implementing these funding measures.

Funding as part of the Federal Act on a Secure Electricity Supply from Renewable Energy Sources

In addition to the above-mentioned funding under the CO2 Act, the Federal Act on a Secure Electricity Supply from Renewable Energy Sources provides for a range of funding measures. The aim of these measures is to support the expansion of renewable energies and contribute to achieving the net-zero target.

The SFOE is responsible for implementing these funding measures.
