The UN Secretary-General is marking ‘Clean Air Day’ with a call for global investment in solutions that tackle climate change and the increasing public health, environmental, and economic harm caused by air pollution.

This year’s International Day for Clean air and Blue Skies, celebrated annually on 7 September, is focused on the theme ‘Invest in #CleanAirNow’ and highlights the economic, environmental and health benefits of investing in clean air.

The Day was established in 2019 after the UN General Assembly noted how detrimental air pollutants are and recognised the importance of clean air for people’s lives. 

UN chief António Guterres said pollution is a silent killer that can be stopped and urged the world to “invest now, so we can breathe easy”. 

Mr. Guterres highlighted how harmful pollution can be, noting that 99 per cent of humanity breathes polluted air which leads to millions of global premature deaths.

Pollution is also choking economies and heating up our planet, adding fuel to the fire of the climate crisis,” the UN chief said. “And it disproportionally affects those most vulnerable in society, including women, children, and older persons.” 

The Secretary-General said investing in clean air will take action from governments, businesses, development organizations and more at a regional and global level.

Mr. Guterres is encouraging the relevant stakeholders to decrease their use of fossil fuels, transition to clean cooking and increase air quality monitoring.

“​​Investing in clean air saves lives, combats climate change, strengthens economies, builds fairer societies, and advances the Sustainable Development Goals,” he said. “…let’s invest now so we can breathe easy knowing we are securing a healthier planet for all.”
