Supreme Court leaves in place two Biden environmental regulations

The Supreme Court left in place Friday two Biden administration environmental regulations aimed at reducing industry emissions of planet-warming methane and toxic mercury.

The justices did not detail their reasoning in the orders, which came after a flurry of emergency applications to block the rules from industry groups and Republican-leaning states. There were no noted dissents.

The high court is still considering challenges to a third Environmental Protection Agency rule aimed at curbing planet-warming pollution from coal-fired power plants.

The regulations are part of a broader effort by the Biden administration aimed at curbing climate change that includes financial incentives to buy electric vehicles and upgrade infrastructure, and rules tightening tailpipe pollution standards for cars and trucks.
