Testing the 'Party Matters' Thesis: Explaining Progress towards Kyoto Protocol Targets.

There is growing interest in whether and how parties matter. We add to this discussion by exploring the ways in which parties matter for policy outcomes. To do this, we look at the European Union (EU) member states' progress towards the greenhouse gas emissions targets set for them by the Kyoto Protocol and the EU's Burden Sharing Agreement. We find that governments that are more pro-environment and less ideologically divided make better progress towards their targets. We also demonstrate that green party representation in government predicts convergence. This article contributes to research examining the ways in which parties matter as well as the growing literature on coalition politics and veto players. [ABSTRACT FROM AUTHOR]
