This report reviews countries’ policy actions with regards to the mandate provided by a United Nations Environment Assembly resolution on preventing and reducing air pollution to improve air quality globally. It builds on the United Nations Environment Programme 2016 report Actions on Air Quality, which provided an overview of actions undertaken by countries around the world, focusing on a set of measures that if adopted would significantly improve air quality.
The new report assesses actions in key sectors that contribute to air pollution, focusing on industrial emissions, transportation, solid waste management, household air pollution and agriculture emissions. It also provides an overview of non-sectoral air quality management actions, including air quality frameworks, strategies, standards and monitoring.
