Update of Austrian PM emission inventory Wilfried Winiwarter, Hermann Schmidt-Stejskal, Andreas Windsperger and Traute Köther 10th joint TFEIP/EIONET meeting, Vienna, May 11/12, 2009

© systems research Situation in Europe Some national activities are in place Combustion emissionen well covered (relatively to fugitive) – still far from satisfactory Certain sectors receive more attention: transport, stack- based industrial emissions Priorities for future work: agriculture, construction, quarries
