Coordinated action against air pollution and climate change could save millions of lives, slow global warming and generate roughly $15 in economic benefits for every $1 spent, according to a new UN-backed assessment.
The analysis by the United Nations Environment Programme and the Climate and Clean Air Coalition examines 25 proven measures and policy reforms that address the two crises together. They include wider use of renewable energy, electric vehicles and cleaner fuels for cooking.
The assessment says joint action can improve public health, strengthen economies and accelerate climate progress because many of the same activities and pollutants drive both global warming and dangerous air pollution.
The findings also underline the enormous health burden created by polluted air. The report estimates that coordinated implementation of the measures could prevent large numbers of premature deaths and cases of chronic disease while cutting major climate and air pollutants.
The climate benefits would extend over decades, with faster emissions reductions helping limit additional warming. The report argues that governments can gain more by coordinating climate, health, energy and air-quality policies rather than treating them as separate policy areas.
The assessment presents clean air spending not simply as an environmental cost but as an investment with measurable economic, health and climate returns.
