  1. Cross Cutting Group B:Ammonia policy context and future challenges Chair: Till Spranger Rapporteur: Zbigniew Klimont Attendees: 13

  2. Scope • What is the agricultural and environmental policy context? • How can scientific understanding help address the future challenges to reduce the negative effects of ammonia?

  3. Policy background issues to be considered • Drivers of ammonia abatement • Ammonia is dominating eutrophication, acidification and secondary PM2.5 concentrations in Europe and deserves much more policy attention • Ammonia abatement in air pollution policies (NECD, GP, AQD) in relation to other legislation, e.g., CAP, Biomass action plan, IPPC, biodiversity, WFD, etc.

  4. How well do we know • Nitrogen effects • Secondary PM formation and effects • Emissions and abatement efficiency • Scope (potential) for abatement • Agricultural production systems and their evolution • Pollutant swapping between different air pollutants • Pollutant swapping between various forms of N

  5. Possible strategy approaches EMISSIONS • Reducing nitrogen fluxes at large • Reducing intensities • Technical abatement measures • Economic instruments • Target setting (ecosystems and health) • Deposition and concentration • Temporal scale • Spatial scale IMPACTS

  6. Where science can help policy • Consequences of revised critical levels • Implications of the ‘ammonia gap’s’ • Consequences of changed seasonal pattern of ammonia concentrations • Link European and local scale abatement and effects assessments • Improve spatial and temporal concentration estimates from models • Analyse ammonia emission reduction policies in a multi-effect, multi-media, multi-scale framework

  7. Discussion/Recommendations (modelers) • Explore possibility of considering local biodiversity action plans in larger scale modelling • Careful evaluation of representativeness of EMEP model results for ammonia concentration • IAMs need either link or include approach for pollution swapping • Incorporate finer temporal resolution (where needed and feasible) in IAMs – example: ‘seasonal measures’ • What to do with the gap’s’? (modelers and policy makers)

  8. Discussion/Recommendations (policy makers) • Work towards elimination of loopholes in legislation (build in synergies) • Steer certain processes more actively, ‘hint’ how to achieve targets • Promote work on specific components, e.g., • N-cycle and effects, e.g., biodiversity • PM health impact assessment, role of speciation • Data on management practices • …

  9. Future challenges – concerns? • Support for resolving possible ‘impact conflicts’ in existing legislation, e.g., animal welfare, organic farming, biomass action plan vs. reduction of impact on ecosystems and human health (from air pollution) • Revision/update of monitoring strategy in the future? • Policy sensitivity to the model output is increasing • Less room for technical measures • Integration of scales (assess relevance and feasibility)
