Pollutant Information: HFCs 

About HFCs

Category: Greenhouse gases

Hydrofluorocarbons (HFCs) contribute to climate change due to their positive radiative forcing effect. Hydrofluorocarbons have a range of global warming potentials (GWP), which are much higher than that of carbon. However, the small quantities emitted mean that despite the high GWP values of the individual gases, the total contribution to GWP weighted greenhouse gas emissions in the UK is small.

HFC emissions can arise from the manufacture of halocarbon chemicals including HFCs themselves, and from the use of HFCs for various purposes. Total emissions of HFCs have increased by 11% over 1990-2015. Although there has been a large reduction in emissions from halocarbon production since 1998, this has been offset by increases in HFC use as replacements for HCFCs and other ozone depleting substances. However, tighter regulations on the use of HFCs are controlling the increase in emissions from their use. Refrigeration and air conditioning (RAC) use is the largest source and contributed almost all (84%) of the total HFC emissions in 2015. Emissions from HFC use in RAC arise due to leakage from refrigeration and air conditioning equipment during its lifetime, in their manufacture and during the recovery of the refrigerants on decommissioning.
