For Europe the CORINAIR emission inventories are available. CORINAIR comprises a European<br />
framework within which country submissions of emission inventories are collected. In CORINAIR, 5-<br />
year advancing emission estimates by source category are stored. It holds inventories for all<br />
substances that are included in EDGAR. CORINAIR inventories have three levels of sector detail,<br />
which are called ‘SNAP 1, 2 and 3-levels’, respectively. The EDGAR inventories have been<br />
compared with CORINAIR at the first level. In order to link the EDGAR source categories to the<br />
CORINAIR sectors the conversion table has been used as presented in Table 1.5.<br />
Basically every country is free to use its own methodology in order to prepare their submission to<br />
CORINAIR. There are comprehensive guidelines such as the Atmospheric Emission Inventory<br />
Guidebook available for making default estimates of emissions but in practise a variety of unique<br />
methods are used. The uncertainty of the CORINAIR estimates varies by country, source category<br />
and substance.<br />

The first step in the validation of EDGAR with CORINAIR has been the comparison of national total<br />
emissions of CO 2 . Table 1.6 lists the results of the EDGAR inventory vs. CORINAIR. Provided that<br />
emission factors do not differ significantly this comparison can give insight in the consistency of the<br />
underlying activity data of EDGAR and CORINAIR. Moreover it can be tested whether the links<br />
between the EDGAR and CORINAIR sectors have been correctly defined. In the second and third<br />
column the unmodified CORINAIR and EDGAR results are presented. The fourth column lists the<br />
ratio. In the CORINAIR inventories the use biofuels is often excluded for various reasons. In some<br />
cases CO 2 emission due to the use of fossil fuels for non-energy purposes and as feed stocks is also<br />
omitted in CORINAIR. Therefore the EDGAR estimates have been corrected for these sources and<br />
the ratios are listed in the last two columns.
