4 Why an emission inventory? 2000/60/EC Water Framework Directive Objectives Assist in establishing and implementing targeted reduction and phasing out measures regarding priority and priority hazardous substances Assist in checking the compliance of the reduction and phasing out measures with the provisions of the WFD (art 4) Estimate the efficiency of the RBMP Programme of Measures (PoM) Allow the establishment of the emission trends over time and other indicators Identify gaps in knowledge, thus the need to develop strategies/policies

5 Why an emission inventory? Data for (mandatory) reporting: Evaluation of the impact of human activity on the status of surface waters (WFD art. 5) The European Pollutant Release and Transfer Register regulation (E-PRTR) Reporting by operators (art. 5) Releases from diffuse sources (art. 9) Inventory on discharges, emissions, losses (EQS Dir. art. 5) State of Environment (SoE) assessment of Europe s water environment (SoE emissions) OECD-Eurostat Joint water questionnaire

38 WEISS briefly stated (1) WEISS calculates emissions from source to sink Making an inventory of all water pollutant sources Monitoring and reporting Scenario, planning and policy assessment The strengths of the system The explicit geographical approach The generic character of the framework and methodology New sources New pathways New pollutants New study areas => The system grows along with the data

39 WEISS briefly stated (2) WEISS does NOT: Involve water quality modelling in the water bodies itself; Model physical or chemical transformation of pollutants dissolved in water while transported; Model seasonal variations in the emissions, their transport, and accounting.
