WHO Air Quality Guidelines and other information resources
How do the WHO Air Quality Guidelines support Member States?
The WHO Air Quality Guidelines (AQGs) inform policy-makers about the health impacts of air pollutants, and provide appropriate targets for air quality that is safe for health. Countries can select among a broad range of policy options for the most appropriate to improve air quality and achieve a better protection of people's health.
The Guidelines are intended for a global audience. They have been developed to support actions for healthy air quality across different contexts. At the same time, they acknowledge the need for each country to set up its own air quality standards to protect the public health of their citizens based on local conditions.
