Case of transboundary air pollution

摘要

The publication deals with transboundary air pollution. Topics are: Critical loads approach; elements of the protocol on further reductions of sulphur emissions. To use the critical loads approach, the information to be needed is such as inventories of current emissions and projections of future emissions, estimates of potential for and costs of emission reductions, long-range transport models describing in quantitative terms the transport of air pollutants within regions, maps of critical loads, and integrated assessment models in which the above elements are combined to assess alternative reduction strategies. The long term goal given in the protocol is to ensure that sulphur deposition do not exceed critical loads. Examples are given. In Germany, the additional costs of sulphur abatement from electricity generation is 1.5 pfennig/kWh
