The International Day of Clean Air for Blue Skies is observed worldwide every September 7. Established by the United Nations General Assembly, this day aims to highlight the dual issue of air pollution, which adversely affects both human health and the environment. It emphasizes the significant health risks associated with polluted air, including chronic respiratory diseases and cardiovascular problems, as well as the environmental impact linked to short-lived climate pollutants that contribute to global warming. The observance encourages cooperation among government agencies, businesses, and civil society to implement effective policies for reducing emissions and improving air quality. The UN Environment Program facilitates this initiative in collaboration with various organizations to unite stakeholders in the fight against air pollution.
