International Day of Clean Air

International Day of Clean Air, observed on September 7, highlights the importance of breathable, pollution-free air for people, communities, and the planet. It encourages greater awareness of air pollution, its effects on health and the environment, and the shared responsibility to help create cleaner, safer places to live.

The observance is an invitation to learn more about the sources of air pollution and support meaningful solutions—from cleaner transportation and renewable energy to protecting green spaces and reducing waste. On September 7, people around the world can take a moment to reflect on how everyday choices and collective action can contribute to healthier air for everyone.

The **International Day of Clean Air** is observed on **September 7**. Its creation reflects growing international concern about air pollution, which is linked to respiratory and cardiovascular disease, premature deaths, ecosystem damage, and climate pressures. The observance also recognizes that polluted air crosses national borders, making cooperation among governments, cities, businesses, scientists, and communities essential.

The United Nations General Assembly formally established the day through **Resolution 74/212, adopted on December 19, 2019**. The initiative was advanced with support from the Republic of Korea and the United Nations Environment Programme. The first observance took place on **September 7, 2020**, under the title “International Day of Clean Air for Blue Skies.” The resolution called attention to the need for stronger international efforts to prevent and reduce air pollution and encouraged countries to share knowledge, technology, and effective environmental policies.

Over time, the observance has developed into an annual platform for public education and policy discussion. Governments and environmental organizations use **September 7** to highlight sources of pollution—including transport, industry, energy production, agriculture, waste burning, and household fuels—and to promote measures such as cleaner energy, improved public transportation, emissions monitoring, and better urban planning. Annual campaigns have also emphasized that clean air is connected with public health, climate action, sustainable development, and environmental justice.

Culturally, the day gives communities a shared language for discussing an environmental problem that is often invisible but affects daily life. Schools, health organizations, scientists, and civic groups may mark **September 7** with awareness campaigns, public lectures, air-quality information, tree-planting activities, or calls for stronger protections for vulnerable populations. Its broader significance lies in presenting clean air not merely as a local environmental preference, but as a common public good and a foundation of human well-being.
