2.8 General Assessment of Completeness

Last updated on 24 Jan 2013 17:05 by Kevin Hausmann

In 1998, the Federal Environment Agency (UBA) launched activities to identify data gaps in the emission inventories and to examine the opportunities for closing these gaps. This work was stepped up particularly against the background of the development of the CSE (Central System of Emissions), since it was important to transfer the existing decentralised data stocks on the inventories (for different pollutants and differnt reporting obligations) into the central database. Hence, facilitated by two research projects, a concept was developed for reorganisation of data records on emissions. Apart from an overall concept on data maintenance, the results included a clear representation of current reporting capabilities, as well as a catalogue of gaps. The overall documentation concept has been integrated within the prepared CSE and, in the framework of a research project, has been adapted to harmonised international reporting obligations (NFR and CRF). It has been taken into account in the national review which the national system and the CSE passed successfully. In addition, the catalogue of gaps is updated each year, keeping up with new research and review findings.

As additional information, there is a specific overview on the completeness of the German POP inventory available. The completeness of the German inventory as a whole has also been assessed in the 2010 stage 3 review report.

The following sections touch on a few source-category-specific approaches for improving the completeness of the inventory.


All combustion-related activities (1A) are recorded in full. At certain points, the energy balance report of the Federal Republic of Germany is supplemented if it is evident that complete coverage is not achieved in selected sub-sections (such as the non-commercial use of wood, secondary fuels). In some source categories, separation of combustion-related and non-combustion-related emissions from industry requires further verification. In general, avoidance of duplicate counting is an important part of quality assurance for such categories.

Industrial processes

In the area of industrial processes, for the application of higher tier approaches some use is made of production data from association statistics and of manufacturers' information. In the interest of the inventory's completeness and reliability, where emissions reporting is based on such sources, checking of source-category definitions and data-collection methods will continue to receive priority. The inventory is considered complete for main industrial processes. Nevertheless, there are still certain categories awaiting further examination, though their contribution to the national total emission is expected to be minor.


In the area of agriculture, while survey data from a past research project on management systems in animal husbandry are available, an effort is being made to carry out periodic, representative data surveys, in the interest of the inventory's continuing completeness and consistency. Further improvement in terms on completeness can be expected for future submissions.

Other sources

In the framework of another research project, other countries' inventory data under the category "other sources" was analysed in order to support a systematic review of the completeness of Germany's national emissions data. The study was designed to show which of the source categories other countries report on are also emissions-relevant in Germany. National inventories were (or will be) improved accordingly. The results of this analysis show that systematic review for completeness needs to be expanded, especially in the area of industrial processes.
