Check Your Refrigerant’s Impact

Find out what action to take with the GWP calculator

Use our simple GWP Calculator for refrigerants to quickly find the Global Warming Potential (GWP) of the gas used in your air conditioning or refrigeration equipment. Just enter the refrigerant name and the quantity loaded — the tool will instantly provide the GWP value and outline the action you need to take to stay compliant with F-Gas regulations in the UK.


  • All you have to do is enter the name of the refrigerant you use and how much of it you load into your equipment.
  • You will also learn what action you need to take along with the GWP value.
  • The following section explains what the GWP value means.
