Abstract

The EU Water Framework Directive (WFD) requires Member States to protect their inland (and coastal) surface and groundwater bodies. However, the way in which WFD requirements can be met, including the associated stringent environmental quality standards, is less clear. This paper presents selected results from the ScorePP project (an EU Framework Programme 6-funded consortium) which developed and assessed the performance of a series of emission control strategies (ECS) at an urban scale. Data from the literature, in combination with expert judgement (where data was not available), have been used to develop semi-hypothetical case cities (SHCCs), which represent virtual platforms for the evaluation of ECSs using substance flow analysis. The results indicate that the full implementation of existing legislation is capable of reducing total emissions of Cd and Hg by between 11% and 20%. Consideration of emissions on a compartment-by-compartment basis indicates that the impact of a particular ECS is sensitive to both pollutant and city-specific characteristics. Whilst reductions in emissions to one compartment are typically associated with an increase in emissions to an alternative compartment, the final compartment is influenced by the type of ECS selected. Limitations of the current approach are discussed.
