These slides will inform you abut the Montreal protocol

1. Montreal Protocol 1987

2. • The Montreal Protocol on Substances that Deplete the
Ozone Layer is a global agreement to protect the Earth’s
ozone layer by phasing out the chemicals that deplete it.
This phase-out plan includes both the production and
consumption of ozone-depleting substances. The
landmark agreement was signed in 1987 and entered into
force in 1989

3. • The parties to the Protocol meet once a year to make decisions
aimed at ensuring the successful implementation of the
agreement. These include adjusting or amending the Protocol,
which has been done six times since its creation. The most recent
amendment, the Kigali Amendment, called for the phase-down of
hydro fluorocarbons (HFCs) in 2016. These HFCs were used as
replacements for a batch of ozone-depleting substances
eliminated by the original Montreal Protocol. Although they do not
deplete the ozone layer, they are known to be powerful
greenhouse gases and, thus, contributors to climate change.

4. • The Montreal Protocol provided a set of practical,
actionable tasks that were universally agreed on. The
Protocol has successfully met its objectives thus far and
continues to safeguard the ozone layer today. Thanks to
the collaborative effort of nations around the world, the
ozone layer is well on its way to recovery.
