Impact of Ozone Layer Protection on the Avoidance of Climate Change: Legal Issues and Proposals to Address the Problem

This article examines some of the issues raised by the interconnections between efforts to protect the ozone layer and efforts to address climate change. It focuses on the replacement of certain ozone-depleting substances with alternatives that have high global warming potential, and the proposals made by some countries to address the resulting problems by placing the responsibility on parties to the Montreal Protocol to control these alternatives. The article also discusses some of the challenges of having two or more regimes deal with the same subject matter, albeit in different ways, and highlights the need for cooperation and coordination across regimes.
