1 Non-State Actors and Environmental Governance: Comparing Multinational, Supranational and Transnational Rule Making

held in Stockholm, as the event that heralded the active involvement of non-governmental organizations (NGOs) in international policy making. In the intervening years, NGO participation in international policy making has grown exponentially, as has the number of multilateral environmental conventions, global environmental conferences and other efforts to facilitate a global governance of the human environment. The increasing numbers of NGOs with a stake in global environmental politics has been well documented, as has the presence at multilateral negotiations and their influence on negotiation outcomes (Betsill and Corell 2008). This paper examines the role and influence of non-state actors (NSAs) in multinational, supranational and transnational policy making. We have selected three models of rulemaking to help explain the role and influence of NSAs in different governance systems, reflecting developments within global environmental governance over the past three decades. Whereas multinational cooperation remained the model of choice whenever international environmental rules were created until the 1980s, the model has been joined in recent years by supranational and transnational rulemaking models
