International Day of Clean Air for Blue Skies

The UNEP-hosted “International Day of Clean Air for Blue Skies”, will be celebrated globally for the first time on September 7th 2020. The main aims of the day, which will be repeated on September 7th in the years to come, are:

a) To raise awareness of the topic in general (sources, effects (incl. on plants), abatement measures, links to other environmental challenges such as climate change),

b) To share best practices how to combat air pollution and its effects, and  

c) To form a global network of organisations, policymakers, research institutes etc. that will put this topic on the international stage.

In addition, this year’s event will promote the day itself, as well as the link between air pollution and Covid-19 and the proposed “green recovery”. For future years, different formats will be trialled, including potentially topical foci such as effects of air pollution on vegetation (crops, forests).
