The Federal Environment Agency of Germany (UBA) is a policy advising institution gathering data concerning the state of the environment, investigating the relevant interrelationships, making projections and providing federal bodies such as the Ministry of the Environment with policy advice. UBA also provides the general public with information on the environment. One important field of interest is the reactive nitrogen (Nr) issue as Germany is obliged to commit to various Nr associated environmental quality standards. Several projects are set up to quantify Nr fluxes, calculate Nr budgets and balances and support the German integrated Nr policy initiative and several actions on international cooperation.
