Emissions Inventory :… …the main requirements • The source: a need for completeness • The load (quantity and variations) • The parameters • The receiving environment: media and type A comprehensive inventory
The proposed system • Complete coverage for sources • Temporal aggregation : the year • Geographical aggregation : the River basin • The parameters : list from the existing Reporting Obligations
Use of emissions data Example of source apportionment Source apportionment of Nitrogen emissions to water by main basins in France Source: IFEN, State of the Environment report 2002.
Emissions to water :… …a complex problem (2/2) • Multiple pathways • Diffuse sources, scattered and associated definition • Parameters
Existing data collectionsaddressing a selection of sectors • EPER • 56 industrial sectors • Direct/indirect to water, • Yearly, 3 years • EU25 • 26 substances • UWWTD • Urban and food industry • Load and percentage reduction, • yearly, 2 years • EU25 • 5 parameters
Existing data collectionsaddressing in principle all sources • OSPAR / HELCOM • All human activities, All pathways (net emission), • Yearly, 1989 and 1995 / every 5 year • 15 countries / 9 countries • 66 substances / 48 substances • Reduction targets • Eurostat/OECD • All human activities, main pathways, yearly • 28 European countries, + other OECD • 15 parameters
In summary • A Patchy situation… A need for more and reliable data… (to allow source apportionment between Agriculture, Urban and industry sources)
New and emerging data collections • WFD • All significant sources (point and diffuse) • All significant pathways, • Yearly, every 6 years • EU25 • 33 priority substances + other EU legislative instruments • Extended with Water Information System for Europe (WISE) • For all EU-level users
New and emerging data collections • PRTR • UWWTP, IWWTP, Aquaculture, diffuse and dispersed • Emission and transfer • yearly • 36 countries • 70 substances
