According to the Federal Council's "net zero" goal, no more CO₂ emissions are to be emitted in Switzerland by 2050. The energy consumption for mobility is to decrease massively and only renewable energy should be used. A CO₂ reduction will only be achieved if the renewable energy for mobility is not simply withdrawn from the energy system since it is then lacking in other energy sectors. Instead, unusable, temporarily surplus renewable electricity should be used or renewable energies should be expanded.

For electromobility, the main focus lies on the intermediate storage of electricity in grid or vehicle batteries and the electrolytic conversion into hydrogen for use in fuel cell vehicles. In order to cleanly power conventional (hybrid) vehicles, hydrogen is converted into synthetic fuels using CO₂. The carbon dioxide (CO₂) for this chemical conversion is taken from the atmosphere. During subsequent combustion in the engine, CO₂ continues to be produced - but only just as much as was previously removed from the atmosphere for the production of the synthetic fuel. The carbon cycle is thus closed.
