Countries in South Asia and Southeast Asia are experiencing severe air pollution problems. Most countries lack technical capabilities and adequate air quality management (AQM) infrastructure. A capacity building workshop on AQM was organised from 19–23 September 2022 for countries in South Asia and Southeast Asia. A total of 17 countries (eight in South Asia and nine in Southeast Asia) participated in the workshop. Each country was invited to present on available AQM infrastructure, including challenges and needs. This article synthesises information on available AQM facilities, challenges and needs of the countries.
