Context: The Climate and Clean Air Coalition (CCAC) has introduced the Air Quality Management Exchange Platform (AQMx) to support global efforts in improving air quality. This platform provides air quality managers with tools and guidance to meet WHO Air Quality Guidelines and interim targets.
Developed in response to a UNEA-6 resolution for increased global cooperation, AQMx will facilitate the sharing of best practices and data, ultimately supporting better policies and health outcomes worldwide.
About CCAC:
Founded in 2012 within UNEP, CCAC is a partnership of over 160 governments, NGOs, and organizations. India joined in 2019. It focuses on reducing short-lived climate pollutants like methane and black carbon.
WHO Air Quality Guidelines (AQG): These guidelines provide limit values for pollutants such as PM2.5, O3, NO2, SO2, and CO, recommending safe levels and interim targets. For example, the 24-hour mean for PM2.5 should not exceed 15 µg/m³, and the annual mean should not exceed 5 µg/m³. The guidelines have been significantly updated from 2005 to 2021.
