WHO: ‘New WHO Global Air Quality Guidelines aim to save millions of lives from air pollution’

Copenhagen and Geneva, 22 September 2021

Air pollution is one of the biggest environmental threats to human health, alongside climate change.

New World Health Organization (WHO) Global Air Quality Guidelines (AQGs) provide clear evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood. The guidelines recommend new air quality levels to protect the health of populations, by reducing levels of key air pollutants, some of which also contribute to climate change.

Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. For that reason, and after a systematic review of the accumulated evidence, WHO has adjusted almost all the AQGs levels downwards, warning that   exceeding the new air quality guideline levels is associated with significant risks to health. At the same time, however, adhering to them could save millions of lives. For further reading, click here.
