Accelerating Access to Clean Air for a Livable Planet

Air pollution is taking a heavy toll on both people and economies across the world. Reducing it will require effective, targeted, and integrated policies. This report identifies the main sources of air pollution in the world today, with a focus on ambient fine particulate matter (PM2.5). It deploys scenario modeling to assess the extent to which current air pollution policies will reduce exposure to PM2.5 by 2040, and to show how adopting an integrated suite of decarbonization and air quality management policies could yield significant progress towards clean air, with substantial co-benefits. The report also assesses strategies and financing requirements to mobilize clean air investments, and emphasizes the features of effective air quality management governance.
