Part 8 Methyl bromide

Chemical formula		Substance		Ozone-depleting potential
CH₃Br		(Mono)bromomethane		0.6

Part 9 Bromochloromethane

Schedule 1 Part 9: added, on 16 November 2000, by regulation 14 of the Ozone Layer Protection Amendment Regulations 2000 (SR 2000/211).

Substance		Number of isomers		Ozone-depleting potential*
CH2BrCl		1		0.12

*Notes:

Ozone-depleting potential is determined in accordance with the relevant Annexes to the Montreal Protocol.

Where a range of ODPs is indicated, the highest ODP value in that range shall be used for the purposes of the Protocol and for the purpose of calculating ODP tonnage under these regulations. The ODPs listed as a single value have been determined from calculations based on laboratory measurements. Those listed as a range are based on estimates and are less certain. The range pertains to an isomeric group. The upper value is the estimate of the ODP of the isomer with the highest ODP, and the lower value is the estimate of the ODP of the isomer with the lowest ODP.
