FLUOROCARBONS COVER 95 PER CENT OF THE FRENCH REFRIGERANTS MARKET
According to the recently released 2010 France refrigerants survey – published by Mines ParisTech/Armines/ERIE for the French ADEME Agency (Inventaires des Emissions des fluides frigorigènes - FRANCE – Année 2010) - the French total demand for refrigerants was 10,224 tonnes in 2010, of which 80 % HFCs (mainly HFC-134a and R-404A), 15 % HCFCs (practically only HFCF-22) and 5 % ammonia and CO2.
