President Joe Biden’s administration approved legislation blocking new coal mining in parts of Wyoming and Montana due to climate change concerns. Republican politicians in both states vowed to challenge and eventually overturn the decision.

The Bureau of Land Management announced its approval of the Resource Management Plan Amendment for the Buffalo Field Office in Buffalo, Wyoming, according to reports. This amendment will prohibit new federal coal mining leases in the Powder River Basin by 2041. The judgment was made over concerns about the amount of greenhouse gas emissions due to coal mining operations, according to documentation.
