Existing scholarship on climate governance has not sufficiently considered the relationship between climate leaders/pioneers and followers. Because of the global commons nature of climate change, unilateral leadership or pioneership by one or a small number of actors will be insufficient to combat climate change effectively. The need to take seriously the relationship between leaders and followers is all the greater in the wake of the 2015 Paris Agreement, which emphasises diffuse, bottom-up action. The relationship between leaders and followers in polycentric climate governance is unpacked in this contribution. What types of actors can be climate followers? Through what pathways can followership emerge and how can we capture the essential characteristics of leader-follower relationships? What conditions facilitate (or hinder) followership? The utility of the approach is illustrated using cases of EU climate leadership and (non-) followership of other actors.
