President Donald Trump has granted a key approval to a major new pipeline that would move oil from Canada into the central U.S. The three-foot-wide Bridger Pipeline Expansion would carry up to 550,000 barrels of oil a day from the Canadian border with Montana down through eastern Montana and Wyoming, where it would link up with another pipeline.

Acting under an earlier order in the case, the administration in February released an analysis that said the decision to resume coal sales would make little difference over time in greenhouse gas emissions from burning coal, a contention critics said was flawed. Attorneys for the plaintiffs argued the administration only considered emissions from a handful of leases and failed to capture the cumulative, long-term impact of the coal program. Yet critics of the coal program note that some lease sales have continued and say the administrations moves could open tens of thousands of acres of public lands to new mining. The coal program is overseen by the U.S. If those mines are to continue operating, they will need to keep expanding onto federal lands, he said.
