1. About Protection of the Ozone Layer
"The Vienna Convention for the Protection of the Ozone Layer" (note1) is a treaty on the framework for international cooperation concerning the protection of the ozone layer, which was adopted in 1985 and entered into force in 1988. It provides observations, research and information exchange on the ozone layer.
"The Montreal Protocol on Substances that Deplete the Ozone Layer" is a treaty on the control of ozone depleting substances (ODSs), which was adopted in 1987 and entered into force in 1989. It establishes the schedule for the phase-out of production and consumption of ODSs, as well as the scheme for trade restriction, etc.
"The Multilateral Fund for the Implementation of the Montreal Protocol" (note2) was established by a decision of the second Meeting of the Parties to the Montreal Protocol in 1990 to assist developing countries in meeting their commitments to the Montreal Protocol.
The Montreal Protocol is recognized as the most successful agreement for protecting the global environment and has become a model for various multilateral environmental agreements.
2. Japan's Contribution
Since becoming a party to these two treaties on September 30, 1988, Japan has contributed to the treaties and the fund as the second largest contributor. Japan also leads the discussion on ozone layer protection through its technologies and experiences.
