EEAPExit – The Environmental Effects Assessment Group (EEAP) assesses the various effects of ozone depletion The original Montreal Protocol, signed in 1987, was the first step in the international effort to protect stratospheric ozone. Under the original Montreal Agreement (1987), industrialized countries were required to begin gradually unblocking CFCs in 1993 and reduce consumption by 20% compared to 1986 by 1994 and by 50% by 1998. In addition, industrialized countries had to freeze their production and consumption of halons compared to 1986. Following the signing of the Montreal Protocol, new data caused more severe damage to the ozone layer than expected. But the CFC industry has not abandoned it so easily. As far back as 1986, the Alliance for Responsible CFC Policy (an association representing the CFC industry founded by DuPont) argued that science was too uncertain to warrant action. In 1987, DuPont told the U.S. Congress, “We believe there is no immediate crisis that requires unilateral regulation.”  And even in March 1988, Richard E. Heckert, President of the Bridge, wrote in a letter to the U.S.
Senate: “We will not manufacture a product unless it can be manufactured, used, processed and disposed of safely, in accordance with the appropriate safety, health and environmental criteria. At present, the scientific evidence does not indicate the need for a dramatic reduction in CFC emissions. There is no measure of the contribution of CFCs to an observed ozone change…  The International Ozone Depleting Substances Treaty (Montreal Protocol) is phasing out the production and consumption of ozone-depleting substances to limit damage to the world`s ozone layer. The Montreal Protocol is signed by 197 countries – the first treaty in the history of the United Nations to achieve universal ratification – and is considered by many to be the most successful global environmental action. The Montreal Protocol on Ozone Depleting Substances is a global agreement to protect the world`s ozone layer by depleting the chemicals that deplete them. This operating plan covers both the production and consumption of ozone-depleting substances. The pioneering agreement was signed in 1987 and came into force in 1989. The United States signed the Montreal Protocol in 1987 and was the leader in managing the treaty`s successes.
