This report describes the activities carried out within the NRP-MLK project ‘Applications of
EDGAR’. These activities focus around the following topics:
ú Validation and uncertainty assessment of the existing EDGAR 2.0 dataset;
ú Monitoring and analysis of trends in emissions and use in integrated assessments such as
RIVM's annual Environmental Balances and the background reports (Environmental
Compendium);
ú Applications of EDGAR data;
ú Update of the database to EDGAR 3.0 (3.2 as publish at the website).
The validation activities provide input into the uncertainty assessment as well as for the update
activities to Version 3.0 (Version 3.2 as presented for public access at the EDGAR homepage
http://www.rivm.nl/env/int/coredata/edgar/). Although uncertainty assessments are an integral part of most
activities, quantitative uncertainty estimates per source category could not made for the EDGAR 2.0
dataset. Therefore, focus was on analysing the differences, also in spatial patterns, with other similar
GEIA datasets (CO 2 ,SO 2 ,NO x ). However, through participation in IPCC activities on Good Practice
Guidance and Uncertainty Management and by comparing EDGAR estimates with official national
figures reported in National Communications, a better knowledge base of the order of magnitude of
the uncertainty per source category has been created. These topics are discussed in Chapter 1.
EDGAR data, supplemented with recent trend data are used in integrated assessments, are used
for trend analysis of global emissions. To illustrate this we provide in Chapter 2 a background
analysis carried out for the Environmental Balance 1997.
The applications of EDGAR data world-wide are discussed in Chapter 3 by presenting
information about downloads of EDGAR files and concrete examples of scientific and policy
applications. An important in-house application was the provision of data for the update of the
IMAGE 2 model.
Finally, we summarise the approach taken to compile EDGAR 3.0 in Chapter 4. This report does
not provide the results of Version 3.0; these are presented in separate reports. Here we build on the
conclusions drawn in Chapters 1 and 2 (validation and user's survey) and summarise key differences
with respect to Version 2.0. Specific issues dealt with are:
ú update of emission factors for 1990;
ú selection of emission factors for 1995;
ú construction of 1970-1990 emissions estimates for CO 2 ,CH 4 and N 2 O (notably for CH 4 );
ú addition of new source categories;
ú update of grid maps used for the spatial distribution to 1x1 degree grid;
ú largest changes compare with Version 2.0.
We hope that the appreciation of EDGAR 3.0 will be similar to the type of reactions we received in
our user's survey of EDGAR 2.0:
I appreciate the effort very much.

I am very glad to have the ammonia emissions inventory.
The EDGAR data are streets ahead of anything else I’ve seen!!!!!
I did appreciate to find an elaborate and comfortable database.

EDGAR database is very useful because it includes many kinds of NMVOC.

Whilst the coding system for sources and sectors is very good, it is not very easy to understand.
Very nice dataset.
