Many cities continue to struggle with severe air pollution, particularly in developing countries. According to the latest State of Global Air (SoGA) report, air pollution was responsible for 8.1 million deaths worldwide in 2021. The World Health Organization (WHO) estimates that air pollution kills approximately seven million people annually, largely due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease (COPD), lung cancer, and acute respiratory infections. Children under five are particularly vulnerable, with over 700,000 deaths in this age group attributed to air pollution in 2021.
