Strategies for the Reduction of Particulate Matter

Strategies for the Reduction of Particulate Matter Load in Ambient Air


Despite of both national and international emission reduction measures, load projection imply that Germany will continue to suffer considerable exceedances of the ambient air limit values for particulate matter PM10. Thus, it is to be analysed, what are the causes of these exceedances, and in how far national measures can contribute to the compliance with the limit values. In this context, two environmental EU Directives (the NEC Directive and the Air Quality Framework Directive) set the framework for clean air management in Europe (and thus in Germany) until 2020.

According to the European Commission’s proposal for a Directive on ambient air quality and cleaner air for Europe, the present PM10 limit value will be maintained and amended with a PM2.5 limit value. The foreseen revision of the NEC directive will probably contain a national emission ceiling for PM2.5. Both directives’ implementation require an assessment of possible emission reduction measures regarding air quality.

The project’s objective is to identify the causes for limit value exceedances for both PM10 and PM2.5 and to identify appropriate emission reduction measures in order to reduce PM load in ambient air.
