Marian Miller provided an engaging and persuasive analysis of the role of Third World states in global environmental negotiations. While Miller focused on the strategies of individual states, this article examines the collective agency of the Third World in global environmental negotiations. The first part of the article explores the debates on the continuing relevance of the Third World as a concept, and contends that the Third World retains relevance in the context of global bargaining processes. The second part of the article highlights the role of ideas and institutions in the continued reproduction of the Third World as an actor in global environmental politics. The final part of the article explores the ways in which the negotiations on climate change have tended to reproduce a distinctive Southern perspective.
