| The manufacture and use of CFCs in industry has been severely curtailed following the Montrol Protocol and subsequent amendments. |
| In recent years, society has introduced new greenhouse gases into the atmosphere, namely CFCs and other halocarbons. |
| If they contain only fluorine, chlorine and carbon they are called chlorofluorocarbons, or CFCs for short. |
| But in focusing on CFCs as a prime cause of ozone depletion in the stratosphere, we have largely forgotten exhaust from space rockets. |
| Once CFCs are released into the atmosphere, only strong ultraviolet radiation can break them down. |
| But methyl bromide and methyl chloride, unlike the CFCs in halides have both human and natural sources. |
