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

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 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) Conclusion
