Overview

• Climate TRACE now maps 137,095 particulate sources worldwide and labels 3,937 as super emitters.
• The coalition’s system fuses data from about 300 satellites, 30,000 ground sensors, and artificial intelligence to identify sources and plumes.
• The website displays who is emitting and provides long-term trend views, with daily, near–real-time updates and weather-app integration planned in roughly a year.
• Initial exposure rankings show Karachi with the largest population affected, followed by Guangzhou, Seoul, New York City, and Dhaka.
• Although soot itself does not warm the planet, it stems from the same combustion that drives greenhouse gases and is linked to millions of deaths annually, with analyses highlighting hotspots such as Cancer Alley.
