HFO-Report

About the report

The refrigeration industry is changing. Due to their high global warming potential (GWP)  the chemical refrigerants HFCs are currently being regulated and phased out by political regulations such as the F-gas regulation in Europe and the international Kigali protocol.

With the current state of the art there are natural refrigerants such as propane, water and air for every refrigeration task which can realize every application safely, efficiently and with a long lifetime.

Nevertheless, new synthetic and chemically more complex refrigerants, the HFO refrigerants, were introduced.

The breakdown product of HFO refrigerant in the atmosphere is TFA which is a highly persistent substance. Due to its longevity, TFA is a danger to the environment and humans, as it has so far unknown consequences for ecosystems and health. We therefore call for an immediate stop to the use of HFO refrigerants and a switch to exclusively natural refrigerants.

In our HFO report, we summarize the current knowledge about the danger and the effects of further usage of HFO.
