In order to better understand the impact of potential measures to reduce ammonia emissions from Agriculture, the Commission has launched a service contract (deadline for answers 25/7/2005). The objective of the contract is to define the most appropriate integrated and consistent actions to reduce various environmental impacts (notably water, air, climate change) from agriculture. Specifically, the objective is to develop and apply a methodology allowing to assess and quantify the costs and the effects of various policies and measures aiming at reducing the impact of agriculture on water, air pollution and climate change. Both ancillary benefits and trade offs of measures need to be identified. The impacts and feasibility of the most promising measures need to be analysed in depth.

The technical annex is available in English (pdf~260K), French (pdf~260K) and German (pdf~260K).

The contract has been awarded to a Consortium lead by ALTERRA (Wageningen - The Netherlands) and including EUROCARE (Bonn - Germany) and AGROTECHNOLOGY AND FOOD INNOVATIONS (Wageningen - The Netherlands). The technical part of the awarded offer is available in EN : Background - Methodology.

The inception report is available in English (pdf~224K). The final report is now available:

A powerpoint presentation (pdf~1,7Mb) has also been prepared by the authors of the ALTERRA reports which summarises the results.

Another service contract has been granted to IIASA in order to integrate into the RAINS integrated assessment model the findings of the contract on "integrated measures to reduce ammonia emissions" as well as the results of an EEA study on the impact of the CAP reform. Potential impacts of the recent WTO negociations as well as of the Biomass action plan will also be analysed. On this basis, additional sensitivity analysis will be achieved notably in the framework of the review of the National Emission Directive. The technical annex of this contract is available form here (pdf~120K) The final report is now available (pdf~612K).

The views presented in the ALTERRA and IIASA reports are those of the contractors and do not represent those of the European Commission.

  • The Expert Group on Ammonia Abatement of the Gothenburg Convention has developped a Framework Advisory Code of Good Agricultural Practice for Reducing Ammonia Emissions, which is to be used as a basis for Parties to draw up national codes and to quantify relationships between recommended control options/techniques and resulting ammonia emissions. The Expert Group seeks to improve the quality of ammonia emission inventories, comparing national inventories, projections and abatement strategies. It considers review of, and possible revisions to, the Guidance Document on Control Techniques for Preventing and Abating Emissions of Ammonia (EB.AIR/1999/2, chap. V). The Expert Group also seeks to address monitoring and modelling questions such as the link between ammonia emission control and the concentrations and deposition of reduced nitrogen compounds.
