Control Measures and Phase out Schedule
Under the Montreal Protocol

The Montreal Protocol and its Amendment constitute a mechanism for the phasing out of ozone depleting substances. Parties to the Protocol are committed to this goal.

The control measures and phase out schedules cover both the production and the consumption of the target substances. However, even after phase out both developed and developing countries are permitted to produce limited quantities in order to meet the essential uses for which no alternatives have yet been identified.

Ninety six (96) chemicals are presently controlled by the Montreal Protocol, including:

Halo carbons, notably chlorofluorocarbons (CFCs) and Halons, Carbon tetrachloride, Methyl chloroform (1,1,1 trichloroethane), Hydrobromofluorocarbons (HBFCs), Hydrochlorofluorocarbons (HCFCs), Methyl bromide (CH3Br), Bromochloromethane (BCM), a new ozone-depleting substance that some companies sought to introduce into the market in 1998, has been targeted by the 1999 Ammendment for immediate phase-out to prevent its use.

The phase out schedules for developed countries are as follows:

Phase out Halons by 1994; phase out CFCs, carbon tetrachloride, methyl chloroform, and HBFCs by 1996;reduce methyl bromide by 25% by 1999, 50% by 2001, 70% by 2003, and phase out by 2005; reduce HCFCs by 35% by 2004, 65% by 2010, 90% by 2015, and 99.5% by 2020, with 0.5% permitted for maintenance purposes only until 2030; phase out HBFCs by 1996 and phase out BCM immediately.
