Cadastre of greenhouse gas emissions in Switzerland

The cadastres display the emissions based on Switzerland’s greenhouse gas inventory distributed geographically on the Swiss territory. The maps do not reflect individual measurements but are based on the greenhouse gas inventory, using simple assumptions for locating the sources of greenhouse gases.

General information on compiling the cadastres of Switzerland’s greenhouse gas emissions is available in the following report:

The maps below show the cadastres of various greenhouse gas emissions (CO2, CH4, N2O and synthetic gases) for the year 2015.

Carbon dioxide (CO2)

CO2 emissions are primarily generated along the road network (transport) and in built-up areas (households, services, industry). Major point sources are cement plants, waste incineration plants and other large industrial plants (refinery, chemical industry, metal, wood and food industry, etc.). Biogenic CO2 emissions or CO2 removals from the atmosphere (carbon sinks) are not reflected.

Methane (CH4)

CH4 emissions mainly arise from cattle farming and manure management and hence occur in rural areas (stables, pastures). Other important sources are old landfills, the gas network and wastewater treatment plants.

Nitrous oxide (N2O)

The main source of N2O emissions is agriculture. The emissions arise from the use of fertilisers and from farmyard manure management (agricultural land, stables). Major emissions also come from individual chemical plants and from wastewater treatment plants.

Synthetic gases

Synthetic gas emissions mainly arise from the loss of refrigerants from cold-storage rooms, refrigerators and air conditioning units. As a result, they occur in populated areas (stationary cooling facilities) and along the road network (mobile air conditioning systems).
