Underpinning evidence for development of policies to abate ammonia emissions - AQ0602APO

The overall objective of this project is to provide underpinning evidence to aid in development of policies to reduce ammonia emissions within the UK. The UK is committed to reducing ammonia emissions through international targets set under the UNECE Convention on Long-Range Transboundary Air Pollution (CLRTAP Gothenburg Protocol) and the EU Nationa Emission Ceilings Directive (NECD), with agreed ceiling targets established for 2010 and ongoing negotiations for revised ceilings to be met by 2020. In addition to meeting internationally agreed ceiling targets, there is also the need to protect sensitive ecosystems (such as SSSIs) from eutrophication and acidification, to which ammonia is a major contributor, and to limit the concentration of atmospheric particulates, of which ammonia is a precursor. This work will be used to support development of Defra’s Ammonia Strategy as well as for engagement with internal and external stakeholders to improve their understanding of the sources of ammonia emissions and mitigation/abatement methods available.

The project will consist of a desk-study, utilising models developed for the estimation and mapping of ammonia emissions from agricultural and non-agricultural sources together with the latest knowledge on mitigation methods and projections for source activity data. The project will deliver:

• an overview of ammonia from agricultural and non-agricultural sources, highlighting uncertainties and sensitivities

• an inventory of activities across all relevant sectors

• a catalogue of mitigation methods including an assessment of their reduction efficiency, applicability, current implementation, costs and barriers to implementation and a wider assessment of potential impacts on other pollutants

• UK ammonia emission projections (including fine resolution mapping) for 2010, 2015 and 2020 based on 'business as usual'

• identification of scenarios to meet the UK 2010 ceiling target and -10%, -20% and -30% of current emission levels
The overall objective of this project is to provide underpinning evidence to aid in development of policies to reduce ammonia emissions within the UK. Specific objectives are to:

1. Review UK arrangements for monitoring [and estimating] ammonia emissions and ambient concentrations;
2. Describe and detail the contribution of different sources of ammonia emissions;
3. Identify potential abatement/mitigation methods and assess the cost and effectiveness of them in reducing ammonia emissions, as well as their wider environmental impacts (both in terms of benefits and dis-benefits to e.g. water quality, climate change etc);
4. Link in with Agriculture Change & Environment (ACE) Observatory funded project ‘Business as Usual III’ to enable assessment of the impact of current EU and UK policies on ammonia emissions (through analysis of impacts on mitigation methods) from various industries, including an assessment of uncertainties;
5. Provide refined projections of ammonia emissions and risks to sensitive ecosystems (SSSIs, SACs and SPAs) for present day, 2010, 2015 and 2020 (under ‘business as usual’), including consideration of health impacts, through formation of PM;
6. Based on most cost-effective abatement, mitigation and other methods [to be discussed with Defra] provide emission projections for emissions and risk maps under scenarios where target ceilings are reduced by 10, 20 and 30 % below current levels to be met by 2020.
