Tehran, Iran’s capital with 14.4 million residents, is grappling with severe air pollution, ranking among the world’s five most polluted cities. The crisis has led to the closure of schools and increased emergency calls, with 357 pollution-related deaths reported in late November. The Air Quality Index soared to ‘unhealthy’ levels, prompting warnings from officials about the dire health implications. Contributing factors include aging vehicles, emissions from power plants, and ineffective enforcement of the Clean Air Act.
