A first-of-its-kind study published on Aug. 25 revealed that 122 companies, dubbed “carbon majors,” are disproportionately responsible for the American West’s water crisis. 

The authors found that from 2014 to 2024, climate change sapped over a third of the West’s typical annual snowpack and decreased streamflows by about 13%. About half of those losses stem directly from 122 fossil fuel companies and cement producers, Jake Bolster writes for Inside Climate News.

“Carbon-major pollution has drained the West of trillions of gallons of water, about the full capacity of Lake Mead, the largest reservoir in the U.S.,” writes Bolster.
