This work, commissioned by the Netherlands Ministry of Housing, Spatial Planning and the Environment, analyzes - in the light of the history of the 1992 Climate Change Convention and of precedents - the aims of the joint implementation provisions of the Convention and the controversies that have arisen about them. It combines a comprehensive study of legal aspects with a penetrating economic analysis and a report on possibilities of joint implementation between the Netherlands and Poland. The book appears at a time when the Convention is entering into force (March 1994) and is the first book on the subject since the Convention was adopted in 1992. It will be of interest not only to academic lawyers and economists with an interest in international environmental developments, but to environmentalists generally and to all those in industry and in public service - nationally and internationally - who are likely to get involved in the practice of joint implementation under this Convention.
