Leadership in EU policy-making: a deep dive into the extension of the EU emissions trading system
通过欧盟建筑、道路运输等新排放交易体系（ETS-2）的案例，研究领导力如何推动政策制定，提出观察领导力的三部分框架，并揭示“顺序领导力”的动态。
This article offers insights into how leadership can be provided to advance the EU policy-making process through a case study of the policy-making for the new EU emissions trading system for buildings, road transport and additional sectors (ETS-2). Conceptually, it contributes to the literature on leadership in the EU by developing a three-part framework for observing leadership in EU policy-making, focussing on the intentions of an actor, the effects of the actions of an actor and the perceptions of other actors. The article also contributes to the literature on interactions between leaders in EU policy-making. Empirically, we provide a process tracing analysis of leadership in the policy-making process for the ETS-2. Using our framework, we examine five key leadership moments, showing how Denmark provided cognitive leadership, Germany provided exemplary and structural leadership, and the Commission and rotating Presidencies provided cognitive and entrepreneurial leadership. Our empirical analysis shows that various types of leadership were partially simultaneously and partially consecutively provided, with some leaders following up on the leadership strategies of others. We term this dynamic ‘sequential leadership’. Our finding confirms the importance of seeing leadership as a relationship, not just between leaders and followers, but also amongst leaders.
