HOW TO CITE Clean Air Fund (2025). The State of Global Air Quality Funding Report 2025. London:Clean Air Fund. ISBN (e-Book): 978-1-0684433-2-9 FOREWORD Air pollution is the world’s largestenvironmental health crisis, yetit receives neither the attentionnor the resources it demands.Each year, eight million people dieprematurely from a crisis that islargely preventable.1Today, nine inten of these deaths occur in low-and middle-income countries, wherethe means to respond are mostlimited.2Without urgent action, thistragic toll will continue to rise. South Africa knows this reality well.The majority of our people breatheair that does not meet WorldHealth Organization guidelines.Independent analysis suggests that,in 2019, air pollution caused anestimated 25,800 premature deaths,5-6% of all national fatalities.3Theeconomic costs are significant too: a2025 report suggested air pollutionled to an estimated 30 million lostworkdays in South Africa.4 Dr Dion George, MP,Minister of Forestry, Fisheries and the EnvironmentRepublic of South AfricaG20 Presidency 2025 Yet, in recent years, we have also shown that progress is possible.

It also aligns with our broader mandate:by investing in cleaner energy, sustainable mobility, and robust environmentalgovernance, we can grow the economy, create jobs, and strengthen the ethicaland capable institutions our people deserve. Our approach in the G20 mirrors efforts globally to place air pollution onthe agenda. Earlier this year, Member States approved the World HealthOrganization’s updated 2025 Road Map, which includes a voluntary target tohalve the health impacts of anthropogenic air pollution by 2040.5In parallel,the emerging Africa Clean Air Programme is defining a continent-wide effort tostrengthen standards, monitoring, and investment for clean air.
