Ozone cartoons timeline.

Period: 1928 to 1928

“Wonder gas” CFCs were invented in 1928 for commercial applications.
Period: 1977 to 1977

“In 1977, the United Nations Environment Programme (UNEP) sets up a co-ordinating committee to study the ozone layer.”
Period: 1978 to 1978

“In 1978, the United States of America, Canada, Sweden and Norway ban the use of CFCs in aerosols.”
Period: 1981 to 1981

“In 1981, UNEP starts inter-governmental negotiations to protect the ozone layer.”
Period: 1982 to 1982

“After 1982, in the absence of other moves, the consumption of CFCs increases again. Industry demands proof of ozone depletion due to CFCs.”
Period: 1985 to 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.”
Period: 1987 to 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.”
Period: 1988 to 1988

“In 1988, the UNEP - WMO report on ozone trends links CFCs to ozone depletion.”
Period: 1989 to 1989

“In 1989, the UNEP Assessment Panel of experts reports THE NEED for tougher controls.”
Period: 1990 to 1990

London Amendment – 1990
Period: 1991 to 1991

“UNEP Assessment Panels recommend that more substances (HCFCs, methyl bromide) are controlled and that the phase out of CFCs is advanced.”
Period: 1993 to 1993

“In 1993, the Meeting of the Parties, held in Bangkok, agrees to a replenishment of the Multilateral Fund
Period: 1994 to 1994

“Halons are phased out by industrialized countries. UNEP Assess- ment Panels recommend tougher controls on methyl bromide.”
Period: 1995 to 1996

“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.”
Period: 1995 to 1996

“Some countries, the Russian Federation and others, report an inability to phase out CFCs by 1996 due to their internal problems.
Period: 1997 to 1997

Montreal Amendment – 1997
Period: 1999 to 1999

The Ozone meetings in Beijing in December 1999 approved a replenishment of the Multilateral Fund of US$ 440 million
