The Nordic countries have been working together for several decades to protect nature and the environment. This report presents the recommendations that have emerged from an external strategic review of the potential for official Nordic co-operation on the environment and climate under the auspices of the Nordic Council of Ministers for the Environment and Climate. The recommendations relate to the following five main areas: specific solutions for a green transition, mobilising key players, funding green transition, international co-operation, and adaptation to climate change.This report is part of a series of strategic and prospective studies commissioned by the Nordic Council of Ministers. Previous strategic reviews have dealt with working life, health and energy. The strategic reviews are part of the Nordic Council of Ministers’ reform programme.
