This report serves as a background document for the policy brief on social and gender inequalities in environment and health that was prepared for the Fifth Ministerial Conference on Environment and Health (Parma, Italy, 10–12 March 2010). It provides an overview of the currently available evidence on the influences and effects of social and gender inequalities on environmental health risks.

Additional chapters present interventions on child-related environmental inequalities and social.
