In 2019, the United Nations General Assembly officially appointed September 7 as the International Day of Clean Air for Blue Skies. This day serves as a platform to heighten awareness and promote global efforts to combat air pollution.

Acknowledging the significance of clean air for people's health and daily well-being, the initiative emphasizes that air pollution poses a significant environmental threat, leading to seven million premature deaths annually. The goal of the day is also to enhance international collaboration in endeavors aimed at improving air quality and mitigating air pollution.
