Tackling climate change requires collective, cross-borders actions and local solutions for mitigation measures. Variety of actors are involved in climate change adaptation and mitigation, ranging from local communities to the global supranational institutions. People tend to perceive individual action as failing to cope with climate change (e.g. outlined in Lorenzoni and Pidgeon, 2006) and therefore ascribe high responsibility to the institutional level. This article will analyze how the public in Baltic – Nordic countries perceive the institutional responsibilities in climate change adaptation and mitigation. This article is based on data of Special Eurobarometer (459), conducted in 2017 and the questions analyzed in this article are related to concerns about climate change and the perception of institutional responsibilities in tackling climate change (institutions: national governments, European Union, business and industry, regional and local authorities; and environmental groups). The local, national and global institutions are perceived as having different responsibilities and impacts in tackling climate change. Also, the perceptions of institutional and individual responsibility varies across the countries. Results indicate that climate change is perceived as one of the top three most serious global issues in Baltic – Nordic countries as well as the concern about climate change in those countries is increasing. Regarding public perceptions of institutional responsibility related to climate change risks, most people in EU member states indicate national governments as having highest responsibility. However, there are significant differences comparing the perception of public in Nordic and Baltic States.
