A joint assessment by the UN Environment Programme (UNEP) and the Climate and Clean Air Coalition (CCAC) identifies 25 proven measures—including renewable energy, electric vehicles, clean cooking and heating solutions, and improved agricultural and waste management practices—that can deliver significant climate and air-quality benefits. The report estimates that implementing these measures could generate annual economic benefits equivalent to 2.8% of global GDP by 2035, rising to 4.5% by 2050 and 11.4% by 2100.
Full implementation of the measures could cumulatively prevent 144 million air-pollution-related premature deaths by 2050 and halve global carbon dioxide emissions compared with baseline scenarios. The assessment highlights the need for governments to integrate climate, air-quality, health, and economic policies to accelerate implementation and maximise these benefits.
