By 2020, greenhouse gas emissions in Switzerland must fall by 20 % below the 1990 level. Under the CO2 Act, this target must be met by measures implemented in Switzerland. The Act prescribes a further reduction in 2021 of 1.5 % compared to the 1990 level.
Under the CO2 Act, greenhouse gas emissions in Switzerland must be reduced by 20% below the 1990 level by 2020. This corresponds to the average reduction target of 15.8 % for the 2013–2020 period to which Switzerland committed internationally under the second commitment period of the Kyoto Protocol. The CO2 Act requires this reduction to be attained by measures implemented in Switzerland, whereas the Kyoto Protocol allows emission reductions achieved through projects abroad. The Federal Department of the Environment, Transport, Energy and Communications has concluded an agreement with the Climate Cent Foundation (Stiftung Klimarappen) for acquiring emission reduction certificates.
National and international targets allow the accountable carbon sink (CO2 storage by Swiss forests and Swiss harvested wood products) to be considered.
We will only know if the target for the 2013–2020 period has been met when the April 2022 greenhouse gas inventory is drawn up. Information on target achievement for the 2013–2020 period is available at:
Transitional arrangement for 2021
Since the total revision of the CO2 Act for the period after 2020 could not enter into force in time for 2021, Parliament agreed in December 2019 on a transitional arrangement. This requires a further reduction in greenhouse gas emissions of 1.5 % in 2021 over the 1990 level.
