Air pollutant emissions in Switzerland have decreased sharply in the past years – among other things, due to stricter threshold values. «Switzerland’s Informative Inventory Report 2021» shows the current development in detail.
Air pollutant emissions in Switzerland have decreased strongly since 1980. Among other things, increased emission limitations in traffic and a limitation of the sulfur content in liquid fuels have led to a strong reduction in pollutants such as nitrogen oxide or sulfuric oxide. For example, the nitrogen oxide reductions were approximately 33 percent lower in the year 2019 than they were in 2005. «Switzerland’s Informative Inventory Report 2021» reports this result.
Switzerland is required to submit an annual inventory of air pollutant emissions in the framework of the Geneva Convention on Long-range Transboundary Air Pollution. On behalf of the Swiss Federal Office for the Environment, INFRAS delivered data and was a co-author of the report. Among other things, INFRAS provided new data on road traffic on the basis of the Handbook for Emission Factors for Road Transport (HBEFA) for the current report.
INFRAS has supported the Swiss Federal Office for the Environment (FOEN) since 2008 in compiling the air pollutant inventory.
