Supreme Court declines to block Biden rules on planet-warming methane and toxic mercury emissions

The Supreme Court on Friday left in place Biden administration regulations aimed at curbing oil and gas facility emissions of methane, a major contributor to climate change.

In a separate action, the court also rejected a bid to block a regulation aimed at curbing emissions of mercury and other toxic pollutants from coal-fired power plants.

In both cases, the court rejected emergency applications without comment, with no noted dissents. Litigation against the Environmental Protection Agency (EPA) will continue in lower courts.
