Air pollution is the largest environmental risk to public health and the fourth leading risk factor for premature deaths globally. Exposure even at relatively low levels poses risks to health. Calls for urgent action on reducing air pollution have been increasing, with organizations worldwide joining voices to promote clean air and establish air quality as a key priority on political, scientific and policy-making agendas. The Global Future Council on Clean Air is promoting an integrated approach to improving air quality based on scientific evidence, strong political action and a participatory approach that includes different stakeholders.
