The Nordic countries are often seen as green both in terms of a good environment and being capable of reducing greenhouse gas (GHG) emissions. This report is concerned with the development in GHG emissions over time and with the policies that have been effective in the reduction path. The purpose of the description is both to highlight effective climate policies and to tell the comprehensive story of climate policy in the Nordic countries. The project is developed in partnership with the Open Climate Network, an international network lead by the World Resources Institute.
