There is serious concern about the impact of the changing climate. The WHO Regional Office for the Western Pacific has taken the initiative in addressing health issues related to climate change, but further action is needed to support efforts to confront climate change in Member States and in various sectors. Health must be mainstreamed into efforts to address climate change, and action must be coordinated and integrated across national boundaries and in all sectors. This report synthesizes information and approaches on climate change and health pertinent to Member States in the Western Pacific Region. It also examines efforts and initiatives by various experts and stakeholders, with an in-depth look at experiences in seven Member States that reflect the diversity of the Region. Finally, it offers recommendations for policy-makers.
