Switzerland's greenhouse gas inventory
The greenhouse gas inventory contains comprehensive emissions statistics in accordance with the requirements of the UN Climate Convention. Switzerland's national and international reduction targets are assessed on this basis. The inventory details Switzerland's greenhouse gas emissions according to the territorial principle and provides a breakdown by gas, sector and individual emission source. It also contains information on greenhouse gas emissions from international aviation and navigation and the greenhouse gas balance of land use (soil, vegetation). The greenhouse gas inventory is updated annually in April with data from the year before last.
The greenhouse gas inventory contains a record of all greenhouse gas emissions in Switzerland. In addition to carbon dioxide (CO2) emissions from the use of fossil fuels, these include in particular those from industrial processes and waste incineration, as well as emissions of the other greenhouse gases methane (CH4), nitrous oxide (N2O) and synthetic gases from a wide variety of sources. The greenhouse gas inventory also includes emissions from international aviation and navigation as well as the greenhouse gas balance of land use, i.e. greenhouse gas emissions and carbon fixation by soils and vegetation. The inventory follows the territorial principle (in the case of motor fuels, domestic sales rather than domestic consumption are taken into account) and therefore does not consider emissions resulting from the production of imported goods (including imported electricity). The emissions data reported in the greenhouse gas inventory are not corrected for weather conditions.
Reduction targets and target achievement review
The greenhouse gas inventory serves as the basis for reviewing Switzerland’s international and national reduction targets. Detailed information on the reduction targets and the target achievement review is available on the following page:
