The Federal Office for the Environment (FOEN) commissioned an update of the inventory data for the production of electricity from coal, peat or lignite and their process chains in the UVEK:2022 database. This update provides the upcoming version of the UVEK:2022 database with updated inventories for these types of electricity productions. Solid fossil fuel power generation is modelled for more than 20 different countries and regions. The update of Life Cycle Inventory (LCI) models was a collaborative effort of the Zurich University of Applied Sciences (ZHAW) and the Swiss Federal Institute of Technology (ETH). The researchers from the Ecological Systems Design Group at ETH are responsible for the update of the key LCI parameters on power plant level (emissions factors, pollutants, and efficiencies). The researchers from the Life Cycle Assessment research group at ZHAW are responsible for the compilation of LCI models according to the recommendations for data quality guidelines according to Frischknecht et al. (2007) as well as the update of methane emissions from coal mining and the hard coal supply mixes.
