Africa: Climate, Clean-Air Action Could Return $15 for Every $1 Invested - UN

What the report says

A new United Nations assessment says governments and investors could see substantial economic returns by tackling climate change and air pollution together. Published by UNEP and the Climate and Clean Air Coalition and reported by Capital FM in Nairobi, the study argues that every US$1 spent on integrated action could generate about US$15 in benefits. The report was released on the International Day of Clean Air for Blue Skies and is presented as a broad economic and health case for combining environmental policies rather than treating them separately.

The assessment says the costs of delay are already large, estimating that each year without action could mean more than US$1.5 trillion in lost benefits. It also links pollution to major health burdens, including millions of premature deaths globally, alongside rising cases of asthma, dementia and other illnesses. According to the report, those health impacts translate into higher healthcare costs and weaker productivity.

The UN-backed study outlines 25 measures across energy, transport, industry, agriculture, household cooking, waste and wastewater. These include cleaner energy, stricter vehicle standards, methane leak reduction, better farm practices and cleaner cooking technologies. If adopted quickly, the report says the package could cut emissions sharply and reduce warming over time.

The broader message is that cleaner air and climate action can be treated as part of economic planning, not only as an environmental expense. The report also notes that fragmented policymaking and weak enforcement remain barriers to implementation.
