In the 1990s, the international community placed both biodiversity protection and trade liberalisation high on its agenda, resulting in the formation of global agreements and institutions, such as the 1992 Convention on Biological Diversity (CBD) and the World Trade Organization (WTO). Distinct in character, they are increasingly linked through the many ways that trade rules affect biodiversity. Developing separately and involving very different communities, there is a risk that the rules and policies of one regime could hinder the effectiveness of the other. This publication seeks to encourage sustainable development by examining and building upon the complementary aspects of these two international regimes. It describes specific proposals fo resolving or avoiding conflicts and for promoting synergies, including opportunities to support effective implementation of the trade-related aspects of the CBD. Intended as background for both trade and environment experts and officials, as well as for environment and development non-governmental organisations
