Historical background
The issue about ozone depletion was first discussed by the United Nations Environment Programme in 1976. In September 1987, several countries agreed upon to reduce and eventually eliminate the use of man-made ozone depleting substances(ODS) under the Montreal Protocol on Subtances the Deplete the Ozone Layer. This is an adoption of the Vienna Convention for the Protection of the Ozone Layer in 1985. The Protocol was amended and substantially strengthened at Conferences of the Perties in London (1990), Copenhagen (1992), Vienna(1995), Montreal (1997) and Beijing (1999).
Montreal protocol in numbers:
2: Number of Nobel prize winners that discovered CFC as a factor in ozone depletion. They are Mario Molina and Sherwood Rowland.
197: Number of countries that singed the treaty and became part of the protocol.

ReplyDeleteThis blog post was an eye-opener for me because this was the first time that I read about and heard about Montreal Protocol. Ozone Depletion has been an ever-present underlying environment issue since the early 1970s, and I think this blog came in handy for me to be more aware of what's really out there when it comes to the talks about ozone depletion.
