English Abstract The UN Economic Commission for Europe through its
International Environmental Data Service delivered data to RIVM for a range
of subjects. Deliveries of data on population (at subnational level) and
emissions to air from combustion (specified by fuel) are looked back upon in
this report. The emissions data specified by sector and by fuel are indeed
digestible for RIVM and its calculation models. Apparent emission factors
were reconstructed from the IEDS emission and energy data for the purpose of
this evaluation. Apparent emission factors and absolute emissions were
compared with reference values from other sources and with default factors
that were estimated for the purpose of this evaluation. The analysis by
RIVM of emissions data brought a great deal of detailed questions to the
surface. The present data set is therefore not used at this stage. ECE has
indicated however that answers are available to most questions. The
problems relate in the first place not to the emissions data proper but to
changes that national respondents made - or did not make - in the prefilled
energy data. The subnational population data have been processed without
noteworthy difficulties and have been used as background information for the
work on Europe's Environment 1993 relating to groundwater. Population data
of human settlements formed a puzzle, among others things because RIVM's
modelling is based on the physical city (the conurbation) that is not
necessarily identical with the administrative city. Also, cities and
agglomerations seem to be mixed up in many data sources. The puzzle was
however solved by RIVM and ECE and a new workable data set was constructed.
From the various sources IEDS data were used most. A series of practical
points is raised and recommendations are given. The service via IEDS,
especially in its role as a clearing house, gets very good marks. The
balance of the cooperation is certainly positive from RIVM's
perspective.
