Costing environmental health intervention

Estimating the costs associated with environmental health interventions (EHIs) is as difficult as estimating their benefits. The objective of this chapter is to provide an overview of the main issues associated with costing EHIs. The second section outlines the two approaches: financial and economic analysis to quantify the cost of EHIs. The third section is devoted to examining the differences between partial and general equilibrium analysis. The fourth section provides suggestions on selecting the appropriate time frame for estimating the costs by summarizing indications from existing cost–benefit analysis guidelines.
