Statute Law Revision Act 2011 (5 of 2011)

Schedule 1   Amendment of principal Acts

Ozone Protection and Synthetic Greenhouse Gas Management Act 1989

88   Paragraph 4(c) of Annex I to the Convention set out in Schedule 2

Repeal the paragraph, substitute:

(c) Chlorine substances

(i) Fully halogenated alkanes, e.g. CCl 4 , CFCl 3 (CFC-11), CF 2 Cl 2 (CFC-12), C 2 F 3 Cl 3 (CFC-113), C 2 F 4 Cl 2 (CFC-114)

Fully halogenated alkanes are anthropogenic and act as a source of ClOx, which plays a vital role in ozone photochemistry, especially in the 30-50 km altitude region.

(ii) Partially halogenated alkanes, e.g. CH 3 Cl, CHF 2 Cl (CFC-22), CH 3 CCl 3 , CHFCl 2 (CFC-21)

The sources of CH3Cl are natural, whereas the other partially halogenated alkanes mentioned above are anthropogenic in origin. These gases also act as a source of stratospheric ClOx.
