Abstract

Integrated assessment modelling aims to bring together information on emissions, atmospheric transport between sources and exposed areas or populations, criteria for environmental protection, and potential emission control measures and their costs, in order to explore effective abatement strategies. We describe the development of a new UK scale Integrated Assessment Model which can be used to investigate strategies for the attainment of national emission ceilings. The model optimises abatement strategies in relation to acidification, eutrophication, and/or human-exposure to particulate PM10, with reference to the deposition of sulphur and nitrogen (oxidised and reduced), and concentrations of primary and secondary particles. The model combines sector specific emissions, atmospheric transport and deposition, ecosystem specific critical load exceedances, and pollution abatement costs to determine optimised abatement strategies using benefit and, where applicable, recovery functions.
