This book enhances economic methods for social cost-benefit analysis of air pollution control measures at point emission sources. A new and highly resolved health damage cost assessment framework is developed and applied, notably in order to evaluate the influence of site-dependent and generic methodological choices. Several of these are shown to have a major impact on resulting health damage costs with important implications for decision-making.This work was published by Saint Philip Street Press pursuant to a Creative Commons license permitting commercial use.
