International Day of Clean Air for Blue Skies—“Clean Air and Sustainable Development”, 7 September 2025
Clean air is important for the health and day-to-day lives of individuals, while air pollution is the leading environmental threat to human health and one of the major preventable causes of death and disease worldwide. Furthermore, air pollution disproportionately affects women, children, and older individuals and also negatively impacts ecosystems.
Today, the international community acknowledges that improving air quality can enhance climate change mitigation, which, in turn, can improve air quality. Encouraged by the increasing global interest in clean air and the need to make further efforts to improve air quality, including reducing air pollution to protect human health, the General Assembly has decided to designate September 7th as the International Day of Clean Air for blue skies.
Echoing the mission of clean air and sustainable development goals, MDPI’s established journals in the environmental and earth sciences field serve as leading platforms for scientific communication. By sharing cutting-edge research and practical solutions, MDPI contributes to global efforts to prevent and reduce air pollution to improve air quality globally.
