Optimizing environmental efficiency; methods and calculations for optimal emission reductions

Optimalisatie Milieurendement; methodiek en berekeningen voor optimale emissiereducties

Synopsis

This report describes methods to select an optimal set of measures to reach specified environmental goals. The described applications concern goals related to atmospheric deposition of acidifying and eutrophying substances. Optimisation is used to search for an optimal spatial allocation of emissions for those substances, or to search for an optimal combination of technical measures to reduce emissions. The goal of the optimisation is to minimize the necessary reductions of emissions or to minimise the corresponding costs. The relationships between emission and resulting deposition are modeled using source-receptor matrices that have deen derived from atmosferic transport models. A number of examples is presented of optimising spatial emission patterns, with minimisation of the necessary reduction of emission as the goal for optimisation. In this report emphasis lies on the methodology used. The presented cases, that have been reported in detail elsewhere, serve as examples of the results that may be obtained.
