Greenhouse gas emissions

In Switzerland, transport, households and industry account for over 70% of greenhouse gas emissions. According to the Swiss Federal Office for the Environment (BAFU), agriculture is responsible for 13.5% (2015) of this. Carbon dioxide emissions only comprise 1.3% of this figure. It is important for agriculture that gases other than CO2 are also classified as greenhouse gases. Methane (CH4) and nitrous oxide (N2O), which have carbon dioxide equivalents of 21 and 310 respectively, are especially important. Compared to methane and nitrous oxide emissions, carbon dioxide emissions in agriculture are insignificant. The most exposed area by a long way is the husbandry of ruminant livestock such as cattle, sheep and goats, which emit methane during digestion. As the emissions only vary negligibly per animal, high productivity is the most important factor for climate-efficient production of milk and meat.

Regional and seasonal

Compared to ruminants, poultry produce fewer greenhouse gas emissions and require less water; pigs effectively utilise by-products. Regional seasonal products considerably reduce climatic strain.
