Policy Implications from the Montreal Protocol :: Environment Kyoto Essays Papers
Policy Implications from the Montreal Protocol    Executive Summary  In the mid 1980s, the international community decided to address the issue of  ozone depletion. In 1987, the Montreal Protocol was signed, setting out abatement  schedules for major ozone depleting substances. Due to several unique factors  surrounding the issue of ozone depletion, the Montreal Protocol was, and continues to be,  a great success. That being said, there are a number of problems that parties to the  agreement have faced over the years, and it is important to learn from these and apply the  lessons to future international environmental agreements. For one, trade leakage was a  major problem for developed nations under the Montreal Protocol. Moreover, other  issues, including illegal trade, technology transfer problems, data collection problems,  and conflicts with subsequent environmental agreements have marred the Montreal  Protocol, and need to be considered when crafting new abatement policies, such as the  Kyoto Protocol.    Montreal Protocol  Up until the late 1920s, the most common artificial refrigerants were toxic and  volatile gases such as ammonia and methyl chloride. It is for this reason that when  chemist Thomas Midgley Jr. developed what appeared to be a safe and inert substitute in  the form of the family of chemicals known as chlorofluorocarbons in 1930, they were  soon widely adopted as coolants for both refrigeration and industrial solvents1. It wasnââ¬â¢t  until a few decades later, in 1974, that two scientists by the names of F. Sherwood  Rowland and Mario Molina proposed that CFC emissions would lead to the destruction of the stratospheric ozone layer2. At that time Drs. Rowland and Molina suggested that  while inert in the lower atmosphere, when CFC molecules reach the stratosphere and are  exposed to ultraviolet radiation they release chlorine atoms that will bond with the  atmospheric ozone to form chlorine monoxide.    Ten years later, in the mid 1980s, Antarctic researchers discovered a large hole in  the ozone layer. This finding seemed to be corroboration of Rowland and Molinaââ¬â¢s  original findings2. With a depleted ozone layer, higher levels of UV radiation will reach  the earthââ¬â¢s surface and cause a range of problems3. These problems can include reduced  plant growth, which would have extensive implications for the agricultural sectors around  the world; higher mortality of phytoplankton, which could affect marine ecosystems and  ultimately fish stocks worldwide; and higher rates of skin cancer and melanoma among  humans. ââ¬Å"A United Nations Environment Programme (UNEP) study [showed] that a  sustained 1 percent decrease in stratospheric ozone will result in about a 2 percent  increase in the incidence of non-melanoma skin cancer, which can be fatal. With the  successful phase-out of CFCs, however, EPA expects 295 million fewer cases of this
