This paper aims to guide city leaders on taking actions to improve air quality in cities, focusing on key sources of pollution such as transportation, energy, industry and materials.
Air pollution is the greatest environmental risk to health, responsible for an estimated 7 million premature deaths globally each year. The problem of air pollution is complex and is particularly pressing in cities. The World Economic Forum 2023-24 Global Future Council on Clean Air has identified nine types of actions currently being used by cities to combat urban air pollution. These actions, outlined in this paper, address pollution across multiple sources and highlight best practices from leading cities.
