“Wonder gas” CFCs were invented in 1928
for commercial applications.

Environment Programme

1977

“In 1977, the United Nations Environment Programme (UNEP)
sets up a co-ordinating committee to study the ozone layer.”

Banning of CFC's

Sweden and Norway ban the use of CFCs in aerosols.”

Inter-govermental

1981

“In 1981, UNEP starts inter-governmental negotiations
to protect the ozone layer.”

Consumption of CFC's

1982

“After 1982, in the absence of other moves,
the consumption of CFCs increases again. Industry demands
proof of ozone depletion due to CFCs.”

Protection of the Ozone

1985

“Governments agree to study, exchange information and
protect the ozone layer - through the Vienna Convention for the
Protection of the Ozone Layer (1985). Scientists continue to find
proof of ozone depletion.”

Cut in Production

1987

“In 1987, 46 governments agree to a fifty per cent cut in the
production and consumption of CFCs by the year 2000; a freeze
in production and consumption of halons by 1992; further
controls linked to assessments by experts.”

Report on Ozone

1988

“In 1988, the UNEP - WMO report on ozone
trends links CFCs to ozone depletion.”

Experts report

1989

“In 1989, the UNEP Assessment Panel of experts reports
THE NEED for tougher controls.”

Phase out CFC's

1990

“Parties agree to completely phase out CFCs by the year 2000,
and to establish a Multilateral Fund to assist developing coun-
tries. US$ 240 million was allocated for 1991 - 1993.”

Unep

1991

“UNEP Assessment Panels recommend that more substances
(HCFCs, methyl bromide) are controlled and that the phase out
of CFCs is advanced.”

Phase out HCFC's

1992

“In 1992, it was decided that the developed countries phase out
HCFCs by 2030, freeze methyl bromide by 1995 and that the
phase out of CFCs be brought forward to 1996.”

Meeting of the parties

1993

“In 1993, the Meeting of the Parties, held in Bangkok, agrees to a
replenishment of the Multilateral Fund - US$455 million for 1994 - 1996.”

Industrialized countries

1994

“Halons are phased out by industrialized countries. UNEP Assess-
ment Panels recommend tougher controls on methyl bromide.”

Russian Federadtion

1995

“Some countries, the Russian Federation and others, report an
inability to phase out CFCs by 1996 due to their internal problems.
The Global Environment Facility (GEF) offers to help them.
Developing countries agree to phase out methyl bromide by 2010.”

Meeting of the Parties

1996

“The Meeting of the Parties held in Costa Rica, approves the
replenishment of the Multilateral Fund and gives US$466 million
for 1997 - 1999.”

Industrialized Countries

1997

“Industrialized countries agree to phase out methyl bromide by
2005. Developing countries will phase out the same by 2015.”

Beijing Declaration

1999

The Beijing Declaration (December 1999) reiterated the
commitment of all Governments to continue full implementation
