What is the Montreal Protocol?

The Montreal Protocol is a protocol to the 1985 Vienna Convention, which is a framework convention, aimed at:

  1. restricting activities likely to damage the ozone layer

  2. cooperation in gathering and exchanging information on the effects of human activities on the ozone layer

The Montreal Protocol creates a timetable for phasing out and eliminating the production and use of substances that deplete the ozone layer.

Revisions were made to the Protocol following scientific evidence that the 1987 targets would not reduce ozone depletion, including:

  1. adding extra substances

  2. adjusting the timetable for phasing-out specified substances

  3. banning trade with non-parties in controlled substances, or products containing such substances

Chemicals controlled

The protocol initially controlled only eight chemicals. It now controls almost 100 chemicals falling into eight groups:

  1. chlorofluorocarbons (CFCs)

  2. halons

  3. other fully halogenated CFCs

  4. carbon tetrachloride

  5. hydrochlorofluorocarbons (HCFCs)

  6. methyl chloroform

  7. methyl bromide

  8. hydrobromofluorocarbons (HBFCs) & bromochloromethane (BCM)
