 Agriculture is an important source of ammonia, contributing to acidification and eutrophication, as well as emissions of the greenhouse gases nitrous oxide and methane. Technical measures to control emissions of one of these pollutants may have an impact on emissions of others. These side effects, which may be positive or negative, are usually ignored in policy-making.
This study investigates interrelations in emission reduction strategies for ammonia, nitrous oxide and methane from agricultural activities in Europe. It presents an optimisation model to identify strategies for simultaneous reductions in emissions of various pollutants at least cost, considering interrelations.
Corjan Brink used the model for an empirical analysis of interrelations in reducing ammonia, nitrous oxide and methane emissions from the European agricultural sector. In many countries, cost-effective ammonia abatement was found to result in an increase in nitrous oxide emissions. Several measures to reduce nitrous oxide and methane emissions simultaneously reduce ammonia emissions. Cost savings can be obtained when interrelations are considered, because measures with harmful side effects are substituted with measures with beneficial side effects.
