Abstract
The selected case studies of the Autonomous Provinces of Bolzano/Bozen and Trento, in Italy, and the Länder Tyrol and Vorarlberg, in Austria, are geographically close and hence confronted with similar challenges on climate change action in multi-level governance systems. This circumstance may lead to different solutions or shared approaches to common problems, as regions act in the framework of their competencies and policies, and also justifies cooperation to develop coordinated approaches amongst Alpine countries.
