Emission trajectories

As a signatory to the United Nations Framework Convention on Climate Change (UNFCCC), Germany is required to elaborate annual emission inventories, including for fluorinated greenhouse gases.

In keeping with the international requirements of the UNFCCC  and the IPCC, Germany is required to compile reports on the nation’s fluorinated greenhouse gas emissions, which going forward will also form the basis for international trading with this category of emissions. Hence such reports require a high level of detail, quantitative information on emissions data uncertainty, and complete  documentation.

Emissions of fluorinated greenhouse gases peak in Germany in 1995, mainly caused by the domestic production of F-gases. After a sharp decline in 2000, emissions rise steadily again until 2017. The main reason is the increasing use of fluorinated refrigerants, the dominant sector since 2000. Since 2018, there has been a clear downward trend. In  comparison to the base year 1995, F-gas emissions fell by almost 40% to 9.95 million tonnes of CO2 equivalents by 2022. The main driver for this development is the steadily increasing use of alternative refrigerants: natural, halogen-free alternatives and F-gases with lower global warming potentials (GWP values).

The F-gases emissions in Germany in total didn´t changed much from 1990 to 2013. But they have been decreasing since 2017. In 2021, total emissions were at 11 CO2-equivalent.
