Problems to fulfill the requirements General reasons: • • • • For collecting new data a modification of the law is necessary The long tradition hinders modification Actually the politics plan to reduce the „statistical burden“ for enterprises „ Länder“ also collect data, this results in double surveys parallel to the statistics - Water politics are primarily in their hand - The European Commission requires data, e.g. Urban Waste Water Directive“ • Other additonal data collection: Environmental agency; EPER • • • Data collection is conducted only every three years Some sectors are not included (services, contstruction, agriculture) Overlapping parts are difficult to report while the statistics are subdivided in two parts © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 14 Wien, 21.06.2005 4.)

Problems to fulfill the requirements Specific reasons • • • • Degree of detailing is particular very high, but the political need is not clear the tables are often organized from a more theoretical point of view Deviation of definitions Conclusion • • • Concentration of the priority data Extension of the use of other databases (UGR, EPER) Improvement of coordination between the different requirements (primarily within the EU) © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 16 Wien, 21.06.2005 Waste water loading scheme POINT SOURCES: Agriculture WW 5.2.2 Industrial Activities (WW_5) WW 5.2.1 •Mining and quarrying •Manufacturing Industry •Prod./Distr.
