Evidence of a filtered approach to environmental monitoring

This contribution focuses on the formulation of optimal inspection strategies and distinguishes between a targeting approach and a filtered approach to monitoring. Using a case study for the Flemish textile industry, we investigate the costs and benefits associated with specific monitoring and enforcement campaigns. The results show the beneficial role such campaigns can play in an effective and efficient monitoring policy. Thus we provide empirical evidence of the advantages associated with the filtered monitoring approach and show that filtering is an interesting complement to targeting.
