This briefing by ECOS shows that there are more climate impacts associated with F-gases than the ones usually considered. Commonly used fluorinated refrigerants contribute to global warming also through the emissions associated with their manufacturing, as well as their degradation. Even the newer fluorinated refrigerants that have a lower global warming potential bring about very worrying emissions. When they undergo degradation, some of these refrigerants split into harmful substances that are currently banned by EU legislation and that modern refrigerants are supposed to replace.
