2.5 Key Categories

Last updated on 04 Dec 2014 08:38 (cf. Authors)

The table below shows the key category analysis for the current reporting year. Dominant source categories vary largely for different pollutants. The key category analysis was carried out in accordance with the EMEP/UNECE guidebook. Due to missing information on uncertainties, a tier 1 key category analysis was selected. Thus, the table gives "L1" for category-pollutant combinations being key categories because of the high level of emissions. "T1" indicates key categories resulting from trend analysis.
Select any pollutant for more detailed results including calculated percentages. Categories are linked to their specific sections of the IIR.

Qualitative criteria to identify Key Categories

According to guidebook section 2.4.3 parties to the convention have to assess qualitative criteria to identify key categories. The German inventory has been carefully checked and it was found that no additional categories need to be marked as key categories.
