Source of the pollutant

HFCs (hydrofluorocarbons) are compounds of carbon, fluorine and hydrogen atoms. Used as refrigerating agents for cooling and air conditioning, as propellants in aerosol sprays and as foam expansion agents, HFCs are the second generation of chlorofluorocarbon (CFC) substitutes, following the first generation substitutes (hydrochlorofluorocarbons or HCFCs). CFCs and HCFCs are both ozone-depleting substances and governed by the Montreal Protocol, but they are also greenhouse gases.


Effect of the pollutant

HFCs contribute to the greenhouse effect. Their global warming potential (GWP) varies depending on the years and molecules considered (see table below for the GWP per molecule (GWP values from the Intergovernmental Panel on Climate Change (IPCC)'s fourth assessment report published in 2007).

Classification of the sub-sectors with the highest emission levels* in 2015

Classification Sub-sectors Share of the sub-sector in total national emissions in mainland France
Tertiary sector including: 45% including:
Refrigeration and air conditioning 42%
Aerosol cans 2.6%
Foam blowing 0.4%
Fire extinguishers 0.1%
2 Food processing industry 12%
3 Residential sector 11%
4 Chemical industry 10%
5 Diesel-fuelled passenger cars 6.8%
6 Diesel-fuelled heavy-duty vehicles (including buses and coaches)  5.4%

*: one sector (out of six: energy transformation, manufacturing industry, residential/tertiary, agriculture/forestry, road and other transport) is broken down into sub-sectors.

(e) preliminary estimate 



HFC emissions in 2015 were estimated at 18.7 Mt CO2e (in GWP tetms). The largest contributor of HFC emissions in mainland France became the residential/tertiary sector, whereas... (to read more, consult the SECTEN report online via your login and password)
