Amicus Brief in Ninth Circuit on Montana Coal Mine Expansion

The expansion of the Bull Mountains Mine project in Montana would allow for an increase in coal production likely resulting in more than $9 billion in climate damages. We filed an amicus brief in the U.S. Court of Appeals for the Ninth Circuit criticizing the Office of Surface Mining’s analysis of the project, which fails to monetize climate impacts using the social cost of carbon. We explain that the project’s full economic benefit is, at most, just one-third of its expected climate costs.
