This article examines the impact of enlargement on European Union performance in energy and climate change policies. It looks at process-driven performance, focusing on agenda-setting, negotiation dynamics and institutional change – as well as outcome-driven performance, looking at the ambitiousness of policy objectives and their implementation. The empirical analysis is based on qualitative, comparative case studies of EU climate change and energy security policies. The article shows that enlargement has had a nuanced but contrasted impact on the two areas. It also points to the recent assertiveness of Central and Eastern European Countries in both energy security and climate policy.
