The final target achievement review for the 2013-2020 period will take place in April 2022 when the greenhouse gas inventory covering the entire second commitment period of the Kyoto Protocol is available. The accountable sink resulting from CO2 storage by Swiss forests and Swiss harvested wood products as well as foreign emission reduction certificates are considered according to clearly defined rules.
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 under the second commitment period of the Kyoto Protocol. The CO2 Act prescribes that this reduction must be attained solely by measures implemented in Switzerland. The Kyoto Protocol, on the other hand, also allows emission reductions achieved through projects abroad to count towards the reduction target. In both cases, the accountable sink resulting from the CO2 storage by Swiss forests and harvested wood products is considered.

The final review of Switzerland’s greenhouse gas emissions for the 2013–2020 period can only be made based on the greenhouse gas inventory for the year 2020, which will be available in mid-April 2022.
Targets by sector under the CO2 Ordinance

For 2015, the CO2 Ordinance prescribed interim targets for the individual sectors:
- Building sector: no more than 78 % of 1990 emissions
- Industry sector: no more than 93 % of 1990 emissions
- Transport sector: no more than 100 % of 1990 emissions
The building and industry sectors attained their interim targets for 2015. Emissions in the transport sector, however, exceeded the interim target.
The explanatory report on the CO2 Ordinance defines the expected contributions to attaining targets in 2020 as follows:
- Building sector: no more than 60 % of 1990 emissions
- Transport sector: no more than 90 % of 1990 emissions
- Industry sector: no more than 85 % of 1990 emissions
