Abstract
Information on the spatial distribution of sensitive receptors may be incorporated into assessments of the potential benefits arising from reductions in sulphur dioxide emissions. Drawing on energy forecasts, illustrative future scenarios for power generation were developed and corresponding national sulphur dioxide emissions inventories constructed. These were used as input to a transport and deposition model. Total sulphur deposition was estimated taking account of other United Kingdom sources and European emissions. Model outputs were overlain on maps of critical loads for soil acidification. Environmental disbenefit was estimated from the number of squares exceeding the critical load and plotted against power station sulphur dioxide
