Only a decade earlier, just 24 countries had signed the Montreal Protocol on Substances That Deplete the Ozone Layer. This treaty, however, was soon ratified by all of the significant producer and consumer nations. It came into force within only 15 months, has now been ratified by nearly 170 countries, and has entered into the annals of diplomacy as a landmark in the history of international cooperation. The heads of the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) described the 1987 Montreal Protocol as one of the great international achievements of the century (Bojkov, 1995).
