The United Nations General Assembly designated 7 September as International Day of Clean Air for blue skies in 2019, with the first Day held in 2020. This designation reflects the global community’s growing awareness of air pollution risks and underscores the need for urgent efforts to improve air quality to safeguard human and environmental health.  

The International Day of Clean Air for blue skies aims to build a global community of action, encouraging countries to collaborate in tackling air pollution to protect the health of people and planet. This day provides a platform for cooperation at individual, national, regional, and international levels to work together.
