Development, examination and evaluation of measures for mitigation of nitrous oxide and ammonia emissions from agriculture

Development, examination and evaluation of measures and concepts for mitigation of nitrous oxide and ammonia emissions from agriculture

Ambitious goals for reduction of emissions have been stipulated on the international, European, and national level to limit climate change and air pollution. They require implementation of efficient mitigation measures. In particular for the emission of nitrous oxide and ammonia from soils it is challenging to develop suitable methods.

Background and Objective

BMEL needs comprehensive and informed advice about options for measures and their impact and interactions. To provide this, the project continuously evaluates new scientific knowledge in an integrated way.


New scientific publications are continuously assessed and evaluated.


Results of this projects were incorporated into numerous expert statements for BMEL, in particular during drafting of the Climate Protection Program 2030 and the National Clean Air Program.
