Political Parties and Policy Change: Explaining the Impact of French and German Greens on Energy Policy

Abstract This article assesses the conditions of partisan influence on public policy change, by comparing the action of the German and French Greens with regard to energy during their participation in the “Red–Green” (1998–2005) and “Plural Left” (1997–2002) coalitions, respectively. First, it highlights the importance of the institutional context in which political parties operate. In Germany, both political and sector-specific institutions made it possible for Die Grünen to have a stronger and deeper impact on energy policy than Les Verts. Second, it emphasizes the strategic and relational dimensions of partisan influence. The ability of the German Green party to foster contacts with the renewable energy industry and experts also explains its policy impact and the success of its strategy focusing on specific issues during its participation in government.
