NextFin news, NEW YORK — On Wednesday, September 24, 2025, former Vice President Al Gore unveiled an expansion of Climate TRACE, a nonprofit coalition's system that uses satellite technology and artificial intelligence (AI) to monitor sources of deadly soot pollution in 2,500 cities globally.
The Climate TRACE platform integrates data from 300 satellites and 30,000 ground sensors to track 137,095 sources of particulate pollution, including 3,937 classified as "super emitters" due to their high emissions. This system enables users to identify not only pollution levels but also the specific sources responsible.
Soot, or fine particulate matter, results primarily from fossil fuel combustion and is linked to millions of deaths worldwide annually, including tens of thousands in the United States, according to scientific studies. Unlike methane, soot does not directly contribute to global warming but poses significant health risks.
Gore emphasized the importance of transparency and public access to pollution data, stating that before AI, it was difficult for people to pinpoint pollution sources in their neighborhoods. He envisions integrating this data into weather apps within about a year, allowing daily updates similar to allergy reports.
Highlighting the health impact, Gore cited the example of "Cancer Alley," a 65-mile stretch between Baton Rouge and New Orleans known for petrochemical industry pollution. Using Climate TRACE data, he noted that if Cancer Alley were a country, its per capita greenhouse gas emissions would rank fourth globally.
The system identifies cities with the highest exposure to soot pollution, including Karachi, Pakistan; Guangzhou, China; Seoul, South Korea; New York City, USA; and Dhaka, Bangladesh.
Climate TRACE's approach aims to empower communities with precise, timely information about air quality and pollution sources, potentially influencing public health policies and individual behavior.
The initiative reflects ongoing efforts to leverage advanced technology for environmental monitoring and public health protection worldwide.
