This paper considers the success of the Montreal Protocol on Substances that deplete the Ozone Layer in addressing an incompletely understood global environmental hazard under risk and uncertainty, and its implications for and interactions with other global environmental protection regimes, particularly the Kyoto Protocol. We illustrate a method for assessing joint impacts of projects and policies designed to reduce environmental damage in the absence of a coordinated legal and regulatory framework. Further, we note areas for improvements in coordination and efficiency across the treaties.
