Total greenhouse gas emissions (without LULUCF)

Switzerland’s greenhouse gas emissions remained roughly stable between 1990 and 2010, despite population and gross domestic product . Since 2010, emission levels have been slightly decreasing, reaching 74% of the 1990 level in 2023. The interannual variability is, in particular, a consequence of weather conditions influencing fuel consumption for heating purposes. The largest contribution to the decrease since 2010 comes from the building sector, .

Switzerland has committed to reducing its net greenhouse gas emissions by at least 50% by 2030 compared with 1990 levels, corresponding to an average reduction of at least 35% over 2021–2030. This includes all sectors (including LULUCF), indirect CO2, and considering the use of cooperative approaches under Article 6 of the Paris Agreement.  and the set out the policies and measures needed to continue and accelerate Switzerland’s efforts to mitigate its domestic greenhouse gas emissions.
