Fluorinated greenhouse gases (F gas) are a group of chemicals containing fluorine. These are powerful greenhouse gases that trap heat in the atmosphere and contribute to global warming.
Ozone-depleting substances (ODS) are gases which damage the ozone layer in the upper atmosphere. They are being phased out, but can be found in older equipment. There are also a few exceptions for certain uses.
Common uses for ODS and F gas include refrigeration and air-conditioning equipment, aerosols, solvents, foam blowing agents, firefighting fluids and high voltage switchgear.
If you manufacture, supply, use, install or service equipment containing F gas or ODS, or if you manufacture or supply F gas, you must comply with legislation which aims to limit such releases.
This guide explains what F gas and ODS are, how to comply with the F gas and ODS legislation, and how the legislation is enforced.
Important: The UK will regulate F gas and ODS if the UK leaves the EU without a deal.
You can find out more about F gas and ODS regulation if there's a no deal Brexit.
If you work with F gas and ODS in the Republic of Ireland you need to update your certification to continue working after 31 October 2019.
