The Effect of European Integration on Swiss Energy Policy and Governance

Matthias Finger, Paul Adrianus Van Baal

The unique “Swiss way” of association with the European Union (EU) has received increasing attention in light of recent events such as Brexit as it is based on sectoral agreements without an overarching institutional framework. As such, Europeanization of ...
