WHO is a leading advocate for policies and programmes to reduce ambient and household air pollution to protect public health at the global, national and local levels.

A wide range of tools that support decisions on air pollution, and more generally for sustainable human settlements and urban planning, has been developed and made available for users by WHO-HQ and by WHO Regional offices. Such tools include models and frameworks, interactive websites, templates, toolkits, and software.| www.who.int
The health impacts from exposure to ambient air pollution or household air pollution are dependent on the types, sources and concentrations of the pollutants in the air pollution mixture to which an individual is exposed. However, the health risks and disease pathways between ambient and household air pollution exposure are often similar, due to their similar composition.| www.who.int
