The Nordic countries have, during the last 20 years, introduced efficient measures to reduce nitrogen losses to the environment. Still, nitrogen losses from the agricultural sector are high. In this report we provide recommendations on strategies and policy instruments to achieve cost effective abatement of reactive nitrogen from agriculture in the Nordic countries.This report is based on a literature review. Additional input was also obtained from discussions at a workshop held in Gothenburg in January 2017. The workshop made it possible for experts from the four Nordic countries Denmark, Finland, Norway and Sweden to come together and discuss and compare policies and mitigation measures regarding nitrogen and agriculture. During the workshop we identified a number of policy challenges, policy actions and also knowledge gaps where further research is needed.
