The European Parliament as an Arena and Agent in the Politics of Climate Change: Comparing the External and Internal Dimension

Climate change policy is a key example for globalized multi-level governance, involving the European Parliament (EP) both as legislator of internal European Union (EU) regulation and discursive agent in global climate negotiations. Based on the comparison of decision-making in external and internal climate change policy, the article investigates the link between the role of the EP as a political actor and arena for the interaction of competing party groups: Does EP involvement in negotiations on legally binding legislation prompt or constrain partisan polarization in comparison to declaratory statements about future goals of climate action? Harnessing a discursive institutionalist theoretical framework, the article compares EP resolutions about annual Conferences of the Parties (COPs 20 to 24) with the revision of four legislative acts for Phase IV of EU Climate Action: namely, emissions trading, effort sharing between Member States, the promotion of renewable energies, and energy efficiency standards. Using roll-call voting data and the review of legislative documentation, the contribution tracks the emergence and negotiation of political conflict in these two sets of cases. Overall, the case studies indicate a low level of external politicization, as indicated by low party group polarization, internalization of political conflict at the committee level, and compromise-building between issue dimensions.
