The United Nations Framework Convention on Climate Change and its follow-up regulations include special commitments on transmission of emission data as well as the data basis (activity data) and applied methodologies. In connection with the international agreements on climate protection, information on emissions have also to be reported to the European Commission. National emissions reporting on the fluorinated greenhouse gases HFCs, PFCs, and SF6 requires establishing
- Emissions of HFCs, PFCs (about 20 individual fluids), and SF6 in metric tonnes and CO2equivalents from industrial processes, by individual sectors,
- Emissions projections of HFCs, PFCs and SF6 in Germany,
- Rating of the effects of implemented and intended emission reduction measures.
In this context the following report was prepared. It consists of three parts.
Part I presents a proposal for a future national F-gas monitoring system designed to provide equal quality of activity data and emission factors with less expenditure. Its main features are efficiency, institutionalisation, and enhancement in data quality. This can be achieved by making differentiated precision demands on emission sources within "key emission sources" and, additionally, by using the new Environmental Statistics Law as well as new databank-based systems for refrigerant management. The new monitoring system is explained sector by sector.
Part II contains both emissions data for the years 1999 to 2003 as required for Germany's emissions reporting on F-gases, and emissions forecasts for 2010 and 2020. The latter are each based on four different scenarios one of which considers the emission reduction effect of the forthcoming EC Regulation on Certain Fluorinated Greenhouse Gases and EC Directive on HFC-134a Phase-out from Passenger Car Air Conditioners.
Part III provides historic emissions data for the year 1990. Their retroactive estimation and documentation is necessary to meet the completeness criterion set out by UNFCCC for national emissions reporting. Due to the extremely high GWP of the then emitting F-gases SF6, HFC-23, and CF4, the 1990 emission level was not very far below that of the year 2003 which is characterised by the new and deliberately produced HFCs.
