Chapter 3 is a “double” chapter: It addresses polar policy making at both the regional and national levels. It pays particular attention to the main regional governance settings that determine policy formulation processes in the Polar Regions and compares different institutional contexts that are important for the Regions’ politics. Specifically, it discusses the significance of different international and regional institutions and frameworks and investigates the principal actors that shape these settings and collaborate in them. It further examines the positions introduced by representatives of state and non-state actors from Canada, the U.S., Chile, and Argentina and identifies entanglements that affect the representation of priorities and interpretations in the (regional and national) politics of the Polar Regions.
