+ | ===== Introduction ===== | ||

The German inventory is generally complete regarding the main pollutants, TSP, particulate matter and CO. National total emissions of these pollutants are considered to be representative and reflect the current emissions situation.

Germany does not report any emission data for years prior 1990. Due to the split into GDR and BRD before 1990, there are no consistent data sets covering what is now the reunited country. Germany has no plans to work on emission inventories for the years 1980 to 1989 in the future. However, some summarizing information on the time span 1970 to 1989 is presented below, also comparing these data to the current emission inventory. | Germany does not report any emission data for years prior 1990.

+ | ===== Completeness in detail ===== | ||
+ | |||
+ | The completeness of the German inventory as a whole has also been assessed by multiple reviews, both under the CLRTAP and the NECD. These reviews all confirm the good coverage of the German inventory. Where there are small omissions, Germany is working continuously to update and complete its data. | ||
+ | |||
+ | The following sections reflect on a few approaches, by source category, for improving the completeness of the inventory. | ||
+ | |||
+ | ==== Fuel combustion ==== | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | In principle, all combustion-related activities (1.A) are recorded in full within the National Energy Balance (NEB) of the Federal Republic of Germany. Nonetheless, | ||
+ | |||
+ | This also applies for the main pollutants, particulate matter and CO. There may be cases, where a further breakdown of activity data and emission factors would be more appropriate to represent any specific technology. In such cases, where the share of a specific technology is very small, the influence of a missing sub-division on the national totals is considered small, too. | ||
+ | |||
+ | In some source categories, separation of combustion-related and non-combustion-related emissions from industry requires further verification. In general, for such categories, avoidance of double counting is an important part of quality assurance. | ||
+ | |||
+ | In terms of heavy metals and POPs, emissions are not yet complete in some sectors due to a lack of appropriate emission factors. Since they may not properly reflect the situation in Germany and in order to avoid inconsistencies within the German inventory as a whole, it is not always advisable to use default emission factors. In addition, fixed default EFs do not reflect the influence of technological developments onto the trends of certain emissions. Nevertheless, | ||
+ | |||
+ | ==== 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' | ||
+ | |||
+ | ==== Agriculture ==== | ||
+ | |||
+ | In the area of agriculture, | ||
+ | |||
+ | ===== Explanation on the use of notation keys ===== | ||
+ | |||
+ | The use of notation keys in the German inventory is carefully checked each year. All notation keys are used as defined in the guidance documents. The following table from the stage 1 review gives a good indication on where and how frequently notation keys are used in the reporting: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | As shown in the table, most flagged cells are the ones reporting on the use of NE. Though NEs are great in number, the actual emission behind each of the notation keys is estimated to be very small. In some cases, it is actually used instead of NA to make absolutely sure to be on the conservative side of the estimate. As for categories, mainly Industrial Processes and Waste are using NEs (please refer to [[https:// | ||
+ | |||
+ | Germany is working continuously to decrease the number of notation keys used and has already made good progress in this regard. | ||
