The NIVA project provided an opportunity to develop several environmental indicators aimed at measuring the impact of agricultural practices on the environment. They focus on carbon storage in soils, the risk of nitrate leaching and the impact on biodiversity. Among the tools developed in the NIVA project for agri-environmental monitoring, the ones on carbon flux/budget are the most advanced. The objective of this policy brief is to present the carbon storage indicator in connection with carbon farming and result-based scheme perspectives.
