Inventories on F-gases, ODS and alternatives
National inventories provide a comprehensive and detailed overview of applications, stock and consumption of ODS, F-gases and alternatives within a certain period. They allow for analyses of the present market situation and estimates of the current and future demand and related emissions. Inventories are essential for the development of political measures for ozone and climate protection as they provide the basis for different scenarios.
We compile inventories on ODS, F-gases and alternatives in different countries. For this purpose we cooperate with authorities, industry and national experts. We review existing inventories and propose improvements.
Reporting of emissions
Parties to the United Nations Framework Convention on Climate Change and the Kyoto Protocol are obliged to annually report data on greenhouse gas emissions. All sources of greenhouse gas emissions (direct emissions) in each country are to be listed in emission inventories. For this purpose, inventory tables in the Common Reporting Format (CRF) and the National Inventory Report (NIR) must be submitted to the UN Climate Secretariat. Furthermore EU Member States have to also report their emissions to the European Commission (Regulation (EU) 525/2013 (Monitoring Mechanism Regulation)). The reporting of emissions provides information on whether national emission reduction targets are met or if further measures need to be taken.
Emissions of the following greenhouse gases need to be reported: Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and fluorinated greenhouse gases (F-gases). F-gases include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3). On a voluntary basis further F-gases may be reported such as unsaturated hydro(chloro)fluorocarbons (unsat. HFCs), hydrofluoroethers (HFEs) and hydrochlorofluoroethers (HCFEs), perfluoropolyethers (PFPE), trifluoromethyl sulphur pentafluoride and nitrogen-containing perfluorinated substances. The reporting on emissions has to be in line with the guidelines of the Intergovernmental Panel on Climate Change (IPCC Guidelines 2006). Data on stock and/or annual consumption serve as input for the reporting of F-gas emissions.
Öko-Recherche has been compiling the data for the F-gas emission reporting for the German Federal Environment Agency for many years. We have established the national F-gas inventory and developed models for F-gas emission estimates from different applications. For the annual emission reporting we update the input data on a regular basis. To do so we interview experts from industry, academia and public authorities. We also contribute to the compilation and improvements of F-gas inventories in other countries and participate in reviews of greenhouse gas inventories.
We are familiar with the appropriate standards for external review of inventories: Effort Sharing Decision No 406/2009/EC (ESD); UNFCCC Guidelines for the technical review of information reported under the Convention related to greenhouse gas inventories, biennial reports and national communications by Parties included in Annex I to the Convention.
