In order to reduce the CO2 emissions from thermal fuels, these fuels are taxed with a CO2 levy in Switzerland according to the CO2 law. The CO2 levy is increased automatically, in case the CO2 emissions from thermal fuels in the years 2012, 2014, and 2016 exceed the thresholds prescribed by the law. The emissions from motor fuels have to be compensated partially. The CO2 statistics documents the CO2 emissions from thermal and motor fuels and is updated annually.
Investigation of CO2 emissions from thermal and motor fuels
The overall energy statistics, annually published by the Swiss Federal Office of Energy, forms the basis for the estimate of the CO2 emissions from fossil fuel consumption. CO2 emissions are derived by multiplication of the declared energy amounts with the corresponding emission factors (see further information below).
Only CO2 emissions from thermal fuels are relevant for the CO2 levy (emissions caused by the internal consumption of refineries are further excluded). The consumption of thermal fuels strongly depends on weather conditions, thus the corresponding CO2 emissions are corrected for weather conditions before the confrontation with the thresholds for the CO2 levy. The correction for weather conditions takes into account outside temperature and insolation. With regard to the achievement of the reduction objectives, emissions are not corrected for weather conditions.
Both the Kyoto Protocol and the CO2 law do not consider CO2 emissions from motor fuels caused by international aviation and navigation.
