The theme for the fourth annual International Day of Clean Air for blue skies, "Together for Clean Air", highlights the urgent need for stronger partnerships, increased investment, and share responsibility for overcoming air pollution. Air pollution, indoors and outdoors, directly impacts human and ecosystem health. We all share and breathe the same air; thus, we all have a responsibility to protect our atmosphere and ensure healthy air for everyone.

According to WHO, almost everyone (99 % of the global population) breathes polluted air. The transboundary nature of air pollution calls for local, national, regional, and global partnerships to tackle the problem. This year’s theme highlights that it is time to invest, work together, and contribute to clean air. Collaboration with UN member states, development organizations, international and regional organizations, the private sector, and civil society is crucial to reducing pollution and improving air quality.

Everyone has a part to play in cleaning our air and protecting our health, and everyone can benefit from it: a safe, clean, healthy, and sustainable environment, including clean air, is integral to the full enjoyment of a wide range of human rights.

On November 26, 2019, the Second Committee of the 74th session of the United Nations (UN) General Assembly adopted a resolution designating 7 September as the “International Day of Clean Air for blue skies”. 

The resolution stresses the importance of, and urgent need to, raise public awareness at all levels and to promote and facilitate actions to improve air quality.
