The US Supreme Court let President Joe Biden’s administration keep using its formulas for estimating the social cost of greenhouse gas emissions when regulating energy and infrastructure projects, giving the White House at least a temporary boost in its efforts to slow climate change.

The justices, without explanation or noted dissent, rejected calls from 10 Republican-controlled states led by Louisiana to reinstate former President Donald Trump’s cost-estimation approach while they pursue litigation to block the Biden policy in a lower court. The Biden method pegs the costs at a much higher rate, meaning more stringent regulation.
