The characteristics of small states generate multiple and contradictory expectations concerning their climate policies and politics. Do small states perceive themselves as market- and rule-takers, which are largely irrelevant to a global problem, and which must prioritise international competitiveness above climate policy goals? Or do their institutions and their small size foster consensus, coordination, and nimble responses to a changing international scene, allowing them to attain competitive advantages and become climate leaders? Climate Politics in Small European States examines how the characteristics of small states structure climate politics and both enable and constrain ambitious climate policies. This volume contributes to our knowledge of how institutions, including electoral institutions and institutions of interest intermediation, actors such as parties, interest groups, individuals, governments, and ideas shape climate policy and politics. The volume also contributes to redressing a deficit in the attention given to smaller states in the study of comparative climate politics. The chapters in this book were originally published as a special issue of Environmental Politics.
