Only recently has international environmental politics scholarship focused more explicitly on “regionalism” as a distinct phenomenon, one which has received much more sustained attention among specialists in international security and international political economy. By the early twenty-first century, regional environmental governance had become commonplace. Since the term “region” has had different connotations in different disciplines, the analytic and empirical scope of studies of regional environmental governance has varied considerably. As such, analyses of regional environmental cooperation have incorporated both constructivist views of regions that transcend the nation-state grid, and rescaling arguments placing greater emphasis on subnational governments, transboundary mobilization, and the importance of ecoregional initiatives. Regional agreements increasingly point to some sort of ecoterritoriality, state actors are increasingly complemented by nonstate or substate actors, and the thematic scope increasingly expands beyond purely environmental issues to encompass broader notions of sustainable development. There are three typical types of regional agreements: interstate regional environmental governance, ecoregional environmental governance, and ecoregional sustainable development governance. Interstate regional environmental governance is most typical of regional economic organizations with an environmental mandate that covers single or multiple environmental issues. Meanwhile, ecoregional environmental governance is widely seen in agreements for mountain ranges, regional seas, or river basins. Case studies on marine and mountain regional environmental governance illustrate that various regional arrangement remain in quite different states of institutionalization. Yet they also illustrate the growth of ecoregionalism in transnational environmental governance.

The terms “region,” “regionalism,” and “regional integration” are often used synonymously in the academe. For instance, one author refers to Pacific Asian regionalization, North American regionalism and regional integration in Europe. Some authors view “regionalism” as the analytically broader term. Since the mid-1990s, there has been a more general movement toward “economic regionalism or regional trade agreements,” building on the concept of “new regionalism” and coinciding with the notion of “preferential trading arrangements.” This implies only those integration schemes which have an economic purpose, are in geographical proximity to each other, and consist of more than two states qualify for inclusion. There are five stages in the deepening of formal regional integration: free trade area, customs union, common market, economic union, and political union. From the late-1950s to the late 1990s, two approaches have attempted to explain the process (rather than the origins) of regionalism: neofunctionalism and liberal intergovernmentalism. Scholars argue whether there is a causal connection between regional integration and Global Political Economy (GPE), or whether they are simply correlated. Three themes from the literature on regionalism and GPE can be identified. First, the numerous studies since the late 1990s that have taken a decidedly comparative approach, irrespective of their level of analysis, agree that there is some “logic” to regional arrangements. Second, confusion occurs with domestic causality. Third, large membership has become a concern for the European Union.
