Chemical compound

Chloropentafluoroethane is a chlorofluorocarbon (CFC) once used as a refrigerant and also known as R-115 and CFC-115. Its production and consumption has been banned since 1 January 1996 under the Montreal Protocol because of its high ozone depletion potential and very long lifetime when released into the environment. CFC-115 is also a potent greenhouse gas.

Atmospheric properties

The atmospheric abundance of CFC-115 rose from 8.4 parts per trillion (ppt) in year 2010 to 8.7 ppt in 2020 based on analysis of air samples gathered from sites around the world.

Property Value
Ozone depletion potential (ODP) 0.44 (CCl3F = 1)
Global warming potential (GWP: 100-year) 5,860 - 7,670 (CO2 = 1)
Atmospheric lifetime 1,020 - 1,700 years
