Some clothing brands have been criticized for subjecting their workers to sweatshop labor. Now, a new map aims to spotlight their environmental impacts too.

The IPE Green Supply Chain Map is a new tool, currently the only one publicly available, that shows how multinational brands’ suppliers are contributing — or not — to air and water pollution in China. The country is the world’s largest producer of textile, and is known for its huge manufacturing industry, including clothing.

The map is an initiative by Beijing-based environmental research organization The Institute of Public & Environmental Affairs and New York-based international environmental advocacy group Natural Resources Defense Council, and contains data for close to 15,000 major industrial facilities in China. It identifies brand suppliers’ name and location, emissions data, waste and water consumption, and environmental violations overtime.

It also provides a visual of air and water quality in different Chinese cities and localities. The map ranks Khotan, a town in Xinjiang province in Western China, as having among the worst air pollution in the country.
