This document has been developed with the aim to provide an overview of currently used methods for economic evaluation and to discuss implications of using these methods for evaluating environmental health interventions. It aims at formulating recommendations for future evaluations in environmental health. The document is intended to contribute to the methodological discussions, and in particular the development of guidelines for evaluation of cost-effectiveness in the framework of WHO’s initiatives, and other ongoing work in this area. This work constitutes a background document with preliminary considerations of methods for economic evaluations in environmental health.
