ABSTRACT How far have Member States in the WHO European Region progressed in implementing the European Commitment to Act on climate change and health? This was the question addressed to members of the Working Group on Health in Climate Change (HIC) of the European Environment and Health Task Force in summer 2012. The HIC members were asked to respond to a comprehensive questionnaire to assess the current status of health-relevant climate change mitigation and adaptation actions. A total of 22 Member States answered the questions focusing on eight thematic areas or topics.
