Who's Polluting Your Air?

Climate Trace's new Pollution Plumes map uses animated markers to dramatically visualize the amount of air pollution people are exposed to worldwide. At the same time, the map reveals the locations of the largest emitters of PM2.5 pollutants into the atmosphere.

By entering your location into the Pollution Plumes map, you can view the locations of all the super emitters near you. The tool also lets you watch animated simulations of air pollution drifting across your area - both on a typical day with prevailing conditions and on a worst-case day when the largest number of people are exposed.

The data behind the Pollution Plumes map comes from Climate TRACE’s global inventory of more than 660 million pollution sources. This database combines facility-level emissions data from power plants, ports, refineries, mines, and factories. You can investigate this data in more detail on Climate Trace's Explore map.

This Explore map provides a global view of greenhouse gas emissions across every major sector of the economy. The map currently highlights emissions from 2021 to 2025, with totals updating dynamically as you filter by geography, sector, or gas type.

The tool is designed for deep exploration and comparison. Users can search for individual facilities, companies, or regions, then break down emissions by sector, gas, or timeframe. It also reveals the world’s top emitters, ranks them, and shows how their output changes month to month. For broader context, the map includes city-level data for more than 9,000 urban areas worldwide.
