Anaylsis of Abatement strategies: Phase V - AQ0910

The work will involve the development and use of European scale (50km x 50km) integrated assessment models combining information on atmospheric emissions, their transport and deposition, environmental sensitivity, human exposure, and abatement measures and costs. Model scenarios will assist UK policy development on the abatement of atmospheric pollutants, with particular attention to acidifying and eutrophying pollutants, and particles, by investigating the cost-effectiveness of different strategies to reduce transboundary air pollution in Europe, and potentially in the northern hemisphere. In addition, the work will involve the development of an integrated assessment model for the UK at a finer scale (~20km x 20km), for SO2, NOx, ammonia and particles, to be used to identify optimum abatement strategies to meet national emission ceilings and to achieve air quality objectives, e.g. for NO2 and particles, as detailed in the Air Quality Strategy for England, Scotland, Wales and Northern Ireland (AQS).
I Undertake a critique of the RAINS model, to provide Defra with a report on the principles and operation of the model, its performance using the source-receptor matrices from the EMEP Eulerian model compared to those from EMEP’s earlier Lagrangian model, and the main areas of uncertainty.

II Critically assess strategies put forward by the EU and UNECE based on the RAINS model, in preparation for and during negotiation. This will often require work at short notice, and the contractor should ensure that adequate cover is available during periods of intense activity.

III Investigate alternative strategies for cost-effective emission reductions in the UK and other European countries, paying close attention to benefits and trade-offs in other areas affecting air quality, such as climate change and transport policies.

IV Conduct a sensitivity analysis or assessment of uncertainties or risks in the integrated assessment modelling approach. The project will involve a continuous scrutiny of the assumptions made and the data used.

V Develop an integrated assessment model to reflect work at EMEP, including the use of 50 km grids, the source-receptor matrices of the new Eulerian model, to include SO2, NOx, ammonia and fine particles (primary, secondary and secondary organics).

VI Develop UK scale integrated assessment model(s) for sulphur and nitrogen compounds, and for particles (primary, secondary and secondary organic). Examine potential strategies and cost and benefits for further emission reductions to achieve specified environmental goals (e.g. using critical loads and dynamic modelling), and to achieve the Air Quality Strategy objectives for NO2 and PM10. This work should consider the effect of alternative energy and transport scenarios (e.g. low carbon initiatives).
