“Researchers have published the State of Global Air (SoGA) 2024 report, which presents data on exposures to and health impacts of common air pollutants, including fine particulate matter (PM2.5), ozone (O3), and, for the first time, nitrogen dioxide (NO2), from 1990-2021. The report finds that while air pollution was the second largest risk factor of death for children under five in 2021, the death rate from air pollution for this group has decreased by 53% since 2000.”
