This issue of Nordic Economic Policy Review explores the implications of new EU-wide climate policy in the Nordic countries. All of them have introduced more ambitious targets for abatement than the EU, but are the national targets and measures consistent with the EU’s new Fit for 55 package? If not, how should national policies be made consistent with EU policy? EU directives set targets for national climate policy, but member states are free to choose the means of achieving them. Are national measures to meet targets set by EU directives efficient? If not, how can they be made so? What are the costs and benefits of national climate policy aiming for more stringent targets than those under Fit for 55? We have put these questions to experts on the economics of climate policy in Denmark, Finland, Norway and Sweden.
