Improve the framework of reduction targets on
multiple levels (e.g. NECD)
Reduce nitrogen emissions from agriculture
(e.g. reform of the Fertilizer Regulation, tax on
nitrogen surplus)
Nature protection measures
Make biogas production environmentally
sustainable
Gradually change food consumption pattern
Reshape the transportation sector by technical
and structural measures
Reduce power plant emissions still further
Develop a national nitrogen strategy

The Federal Ministry for the Environment (BMUB) plans to launch a
national nitrogen strategy by the end of 2016.
National strategy, but alliances or cooperation with local, regional and
international actors are looked for
Important aspects:
To communicate the nitrogen-problem
To develop an overall reduction target
To adjust existing reduction measures if necessary, to find
supplementary reduction measures, to combine all measures in a
sensible way and prioritize them
