Air pollution and the climate crisis are two of the greatest challenges of our time, but they also present an opportunity for us to do better, to be better. Approximately 99% of the world’s population is now breathing polluted air, warns the WHO. Eight million people die prematurely each year due to air pollution, with populations from low- and middle-income countries being exposed to ambient PM2.5 levels that are 1.3 to 4 times higher.

Clean air is increasingly recognized as a global priority.

#WorldCleanAirDay encourages collaboration across borders and boundaries, between sectors and beyond silos to reduce air pollution and leverage finance and investments towards air quality measures and solutions.

Our Campaign

The World Economic Forum has partnered with UNEP to engage the private sector and garner commitments through its new Alliance for Clean Air. The Forum has partnered with industry leaders and experts to scale progress on air pollution reduction. Solutions and best practices will be adopted and featured in the years to come.

This year on 7 September – the fourth International Day of Clean Air for blue skies – pledge to reduce emissions and invest in research and development to imagine new ways of doing business.
