The goal of this study is to estimate the net impact of all measures implemented in the context of the Swiss energy and climate policies on CO2 emissions from combustion processes between 1990 and 2030. The study provides a projection of CO2 emissions until 2030 under the assump-tion of continuation of existing measures and contrasts these emissions with a scenario exclud-ing all policies and measures introduced after 1990. The study does not estimate the evolution of CO2 emissions from non-combustion processes, other (non-CO2) greenhouse gas emissions and the impact of measures on these emissions. Nor does it simulate a scenario with additional measures that are currently discussed but not decided or that may become necessary in the future if it appears that the emission targets cannot be met with existing measures alone.
