In September 2025, Climate TRACE, led by Al Gore, launched a groundbreaking AI-powered tool that tracks the sources and dispersion of toxic particulate pollution (PM2.5) across 2,500 cities and 660 million assets worldwide. Utilizing 300 satellites, 30,000 ground sensors, and advanced atmospheric models, this system identifies “super emitter” facilities responsible for the largest share of health-threatening pollution. Nearly 1.6 billion urban residents are exposed to emissions mapped by the system, which highlights direct neighborhood impacts and global hotspots like Karachi, Guangzhou, Seoul, and New York City. The data shows that these emissions cause millions of premature deaths annually, linked to severe diseases and chronic health risks. By making pollution visible at a local level and naming its sources, the tool empowers global public health action and accelerates pressure to curb fossil fuel usage, transforming environmental transparency and accountability through technology.
