About the day

The United Nations General Assembly adopted the Resolution to hold an International Day of Clean Air for blue skies on 19 December 2019, during its 74th session and invited the United Nations Environment Programme (UNEP) to facilitate the observance of the international day on 7 September in collaboration with other relevant organizations.

This year, #WorldCleanAirDay aims to raise awareness at all levels – individual, community, corporate and government – about the importance of healthy air for healthy people and a healthy planet.

The day provides a platform for strengthening global solidarity and political momentum for action against air pollution and climate change, including increased international cooperation on the collection of air quality data, carrying out joint research, developing new technologies and sharing best practices.
