The central objective is, by using the analytical structure of EDGAR, to serve both policy makers and<br />
atmospheric modellers by providing (a) materials supporting international policy development and<br />
(b) the IMAGE 2 model with up-to-date emission data to calculate regional emissions and other<br />
modellers with emissions on grid. In support of serving these key target groups three types of<br />
activities have been defined:<br />

- with European inventories<br />
- with national inventories prepared for the FCCC (including recommendations to IPCC)<br />
- with GEIA inventories<br />

- annual assessment of emission trends (direct greenhouse gases [GHG] only)<br />
- periodic updates of the inventories (including recent activity data, country specific emission<br />
estimates (CORINAIR, FCCC), NRP results)<br />
- evaluation of key sources/regions in the (updated) inventories and ad hoc advice to policy<br />
makers<br />
- provide inventory data to the IMAGE 2 model, other (NRP) projects, IPCC and to GEIA.<br />

- time profiles<br />
- new compounds<br />
- improved source estimates (e.g. biofuels, biomass burning)<br />
- software modifications<br />
The rationale of these activities will be described below.<br />

At present EDGAR inventories are mainly different from those developed by the Global Emission<br />
Inventory Activity (GEIA), in that the EDGAR inventories are more consistent with respect to<br />
reference year, across sectors and across compounds. Inventories of GEIA, which is part of the<br />
International Global Atmospheric Chemistry (IGAC) project of the International Geosphere-<br />
Biosphere Programme (IGBP), are currently merely joints of regional emission maps, without any<br />
structural detail on the sources. Because of its structured approach, EDGAR facilitates: (a) the<br />
extraction of emission factors aggregated over major sources or specific regions, and (b) the<br />
construction of future and historic emissions scenarios by linkage with a scenario model like IMAGE.<br />
EDGAR will remain faster than GEIA in generating comprehensive emissions data for modellers.<br />
The current version of EDGAR has been validated by comparing global total and regional total<br />
emissions with other estimates, notably those reviewed by the Intergovernmental Panel on Climate<br />
Change (IPCC). One way of validating EDGAR is by comparison of EDGAR/GEIA data with<br />
regional inventories such as of CORINAIR/EMEP and with greenhouse gas (GHG) inventories<br />
submitted to the secretariat of the Framework Convention on Climate Change (FCCC). This will<br />
result in a mutual validation of both EDGAR/GEIA and FCCC national inventories as well as of
