Als Vertragsstaat der Klimarahmenkonvention der Vereinten Nationen (UNFCCC) ist Deutschland seit 1994 dazu verpflichtet, Inventare zu nationalen Treibhausgasemissionen zu erstellen, zu veröffentlichen und regelmäßig fortzuschreiben. Gemäß Entscheidung 24/CP.19 müssen alle im ANNEX I der Klimarahmenkonvention aufgeführten Staaten jährlich einen Nationalen Inventarbericht (NIR) erstellen und übermitteln, der detaillierte und vollständige Angaben über den gesamten Prozess der Erstellung der Treibhausgasinventare bereitstellt. Durch diesen Bericht soll die Transparenz, Konsistenz und Vergleichbarkeit der Inventare sichergestellt und der unabhängige Überprüfungsprozess unterstützt werden. Quelle: www.umweltbundesamt.de
Can TROPOMI-NO2 satellite data be used to track the drop and resurgence of NOx emissions between 2019-2021 using the multi-source plume method (MSPM)?

Nitrogen dioxide (NOx) is an important primary air pollutant, dominantly produced by anthropogenic, mostly combustion based, activities from sectors such as industry, traffic and transport. NOx is directly linked to negative health and environmental impacts. Currently, the construction of emission inventories to keep track of NOx emissions is based on official national reported emissions and proxies such as activity data as well as direct measurements. The effort to properly construct an accurate inventory is significant and time consuming which causes a reporting offset between one and five years with respect to the current date. Next to this temporal lag difficulties in composed inventories can arise from legislative and protocol differences between countries and over time in reporting of emissions. Satellite based atmospheric composition measurements provide a unique opportunity to fill this gap and independently estimate emissions on a large scale in a consistent, transparent and comprehensible way. They give the possibility to check for compliance with emission reduction targets in a timely manner as well as to observe rapid emission reductions such as experienced during the COVID-19 lock-downs. In this study we apply a consistent methodology to derive NOx emissions over Germany for the years of 2019-2021. For the years where reporting is available differences between satellite estimates and inventory totals were within 100 kt. The large reduction of NOx emissions related to the COVID-19 lock-downs were observed in both the inventory and satellite derived emissions. The recent projections for the inventory emissions pointed to a recovery of the emissions towards pre-COVID19 levels this increase was not observed. While emissions from the larger power-plants did rebound to earlier levels, others sectors such as road transport and shipping did not and could be linked to a reduction in the number of heavier transport trucks. This again illustrates the value of having a consistent satellite based methodology for faster projections to guide and check the conventional emission inventory reporting. The method described in this manuscript also meet the demand for independent verification of the official emission inventories, which will enable inventory compilers to detect potentially problematic reporting issues. Transparency and comparability, two key values for emission reporting, are thus bolstered by this technique. © Author(s) 2022

The Informative Inventory Report (IIR) is providing complementary information to Germany's air pollution inventories under the Geneva Convention on Long-range Transboundary Air Pollution of the United Nations Economic Commission for Europe (UNECE/CLRTAP) as well as the EU's National Emission Ceiling Directive (NECD). Germany's air pollution inventory includes emission data in consistent time-series ranging from 1990 (1995 for PM10, PM2.5 and 2000 for Black Carbon) to the latest reported year (2 years back) for nine air pollutants and priority heavy metals & persistent organic pollutants (POP). This report includes a comprehensive analysis of the inventory data, descriptions of methods, data sources, and carried out QA/QC activities. It follows the outline established by the latest guidelines for estimating and reporting of emission data and all data presented in this report were compiled according to those same guidelines.

Satellite-based emission verification

Satellites that measure the chemical composition of the atmosphere are becoming more accurate and numerous, providing a unique opportunity to independently monitor emissions for large geographical regions in a consistent way. This report elaborates the development of a software tool which is able to process satellite observation data and estimate NOx emissions from it for a pre-defined area. The tool is fully operational for processing satellite observations from the TROPOspheric Monitoring Instrument (TROPOMI) and the Ozone Monitoring Instrument (OMI). The tool is modular in design with the capability in mind to digest satellite data from various satellites and for pollutants. It is furthermore designed to be relatively simple and operates without a dependence on complicated and computationally demanding atmospheric models. The methods for satellite based emission estimation can complement data from emission inventories by incorporating independent measurement techniques into the reporting scheme. This would help to identify room for improvement in the compilation of inventories as well as boost the transparency and confidence in the reported data. Quelle: umweltbundesamt.de

As a Party to the United Nations Framework on Climate Change (UNFCCC), since 1994 Germany has been obliged to prepare, publish and regularly update national emission inventories of greenhouse gases. Pursuant to Decision 24/CP.19, all Parties listed in ANNEX I of the UNFCCC are required to prepare and submit annual National Inventory Reports (NIRs) containing detailed and complete information on the entire process of preparation of such greenhouse-gas inventories. The purpose of such reports is to ensure the transparency, consistency and comparability of inventories and support the independent review process. Quelle: www.umweltbundesamt.de
