This report highlights the key findings of the Health and Environment Linkages Initiative, set up by the WHO and UN Environment Programme to identify ways of integrating environment and health considerations into decision-making. The report outlines the ways in which health and environment linkages are usually defined and framed by policymakers, and describes the most common institutional and political barriers they face.

A review of formal impact assessment tools is given, along with a 'menu of options' for good practice application of impact assessment. The report highlights the importance of measuring the impacts of decisions made in terms that can be understood by policymakers. And it offers guidance on how to combine health and environment issues with economic considerations, describing real-world experiences from Jordan, Thailand and Uganda.
