Clean Air Day highlights urgent need to invest in air pollution solutions for global prosperity

Nairobi, 7 September 2024 – The world marked the fifth annual International Day of Clean Air for blue skies today with calls for investment in clean air solutions now, as air pollution causes increasing public health, environmental, and economic harms. More than 99 percent of humanity is now breathing polluted air, leading to more than 8 million annual deaths, including more than 700,000 children under five.

Dirty air disproportionately affects more vulnerable populations such as women, children and older people. Air pollution has become the second leading risk factor for early death globally, overtaking tobacco for adults and second only to malnutrition for children under five. Yet despite already high and still rising economic, environmental and existential impact of air pollution, which each year costs the world USD $ 8.1 trillionin health damages alone, less than 1 per cent of international development funding is dedicated to tackling it. 

In addition to this silent killer’s toll on human health, “pollution is also choking economies and heating up our planet, adding fuel to the fire of the climate crisis,” UN Secretary-General António Guterres said in his message for the day, which the UN General Assembly designated as a day to champion clean air causes in 2019.

Led by the UN Environment Programme (UNEP), this year’s theme focuses on amplifying global calls to Invest in #CleanAirNow to ensure a healthier and more prosperous future for people and the planet.

“Investing in clean air requires actions by both government and businesses to phase out fossil fuels, strengthen air quality monitoring, enforce air quality standards, boost renewable energy, transition to clean cooking, build sustainable transport and sustainable waste management systems, clean up supply chains, and reduce harmful emissions, including methane,” the UN Secretary-General said.

Ahead of Clean Air Day, the UNEP-convened Climate and Clean Air Coalition(CCAC) launched AQMx, a global air quality management platform, on 5 September in response to calls from countries for greater regional knowledge sharing and action on improving air quality that led to a resolution at this year’s UN Environment Assembly (UNEA-6) talks.

UNEP Executive Director Inger Andersen used her Clean Air Day messageto call for greater investment in air pollution solutions in all societies, and an end to the violation of every human being’s fundamental right to breathe clean air.

“We are asking nations, regions and cities to establish robust air quality standards by backing renewable energy and sustainable transport, holding industry to account with strict emission standards, and integrating air quality into climate action,” she said.

“We are asking for strong funding through redirecting fossil fuel subsidies, through grants or microloans for cleaner cooking technologies, and through serious private sector engagement and investment,” she added. “We are asking for collective action, from international development initiatives to individuals that can make small changes in their own lifestyles.”

Events across the world marked the International Day of Clean Air for blue skies: South Africa held a two-day conference, and UNEP supported a webinar to highlight how African cities can avoid open burning of waste. There were high-level discussions in Asia featuring youth voices from across the continent, and a celebration on the site of a former steel mill in Beijing that was transformed into an outdoor Olympic Games area to tackle air pollution. In Latin America, UNEP and Wikimedia held an editing workshop to improve public information on air pollution, and in North America, the CCAC, UNEP and the World Resources Institute hosted a Clean Air Day event that featured speakers from NASA, the U.S. and U.K. governments, and the World Bank.

The good news is that air pollution is preventable, and people around the world are stepping up to address the crisis. Proving that change is possible, some cities have slashed air pollution levels, while countries have committed to reducing methane – a potent air pollutant also driving global warming – through the Global Methane Pledge and developed integrated plans to comprehensively tackle air pollution. A 20 per cent decrease in just one common pollutant, PM2.5, could lead to a 16 per cent jump in employment growth and 33 per cent jump in productivity, while reducing methane emissions could save between USD $4 billion and USD $33 billion by halving crop losses by 2050. Cutting super pollutants could further limit temperature rise and protect food security by preventing up to 0.5°C of warming by 2050. 

To limit harm from unclean air, Governments can, among other measures, set and implement stricter air quality standards, invest in air quality monitoring to identify and track pollution hotspots, build institutional capacity to address air pollution, and integrate clean air measures into national policies and plans. Businesses should invest in clean technologies and practices that reduce emissions and assess their air pollution footprint and make clean air a core aspect of their business planning.

Air pollution knows no borders, and everyone has a duty to protect our atmosphere and a right to inhale healthy air. By working across all regions, sectors, and societies, and investing in cleaning up our air we can collectively breathe easier for generations to come.
