F-gas restrictions push development of refrigerants

Refrigerants in the form of fluorinated gases (F-gases) potentially spell trouble for global warming, but there is a lot of development in the area.
 
The European Commission is in the process of further strengthening the existing regulations on F-gases. There are a few categories of F-gases, and one of them is hydrofluorocarbons (HFCs) which are often used as refrigerants in heating and cooling appliances like air conditioning units and heat pumps.
