The group of fluorinated greenhouse gases (F-gases) includes partially fluorinated hydrocarbons (HFC), chlorofluorocarbons (CFC) and sulphur hexafluoride. These substances are used in a wide variety of applications, ranging from use as refrigerant to the production of certain foams, and in aerosols. Some fluorinated greenhouse gases have very high Global Warming Potential and contribute to global warming.

Global demand for these substances is on the rise, firstly because they replace ozone-depleting substances and secondly because the demand for refrigeration is increasing constantly. Global emissions of F-gases will rise to about 4 Gt CO2 eq by 2050 if no reduction measures are taken. The share of F-gases‘ contribution to the greenhouse effect will climb from 1.3% (2004) to 7.9% relative to global direct CO2 emissions. These are the results of a 2010 study by the Federal Environment Agency. The global emissions study reiterates the necessity of taking further international measures to reduce F-gas emissions, although the study itself is one that assumes a moderate increase in emissions.
A slightly different trend is expected in Germany. The progress in technology and legislation made up to now and their rigorous implementation could lead to a reduction of emissions in the medium term, although the trend might be reversed by a steady rise in number of installations. A “further measures“ scenario was therefore considered, based on a climate-neutral, near-renunciation of the use of fluorinated greenhouse gases. The utilisation of all possibilities can result in a long-term reduction of fluorinated greenhouse gas emissions.
As Party to the Framework Convention on Climate Change (UNFCCC), Germany has committed to prepare and publish emission inventories in German and to update them on a yearly basis. In connection with the international climate protection agreements, Germany is also required to send emissions data to the European Commission once a year.
Reports on emissions of fluorinated greenhouse gases are now more than just a non-binding description of the current situation and an instrument to monitor the effectiveness of measures. These reports will be the basis for future international emissions trading. Hence, a high level of detail, quantitative statements about the uncertainties inherent in the emissions data, and complete documentation are required. The emissions data are therefore determined, as far as possible, in keeping with the IPCC Good Practice Guidance 2000.
The reports on the determination of emissions of certain fluorinated compounds are in part available in English and compiled in the table below:
