The Biden administration has announced the most stringent tailpipe emissions standards in U.S. history. Under the EPA’s plan, new gas-powered passenger vehicles will have to average at least 55 miles per gallon beginning in 2026. Critics note the rule change will effectively restore emissions cuts that were canceled by the Trump administration, and say Biden should do much more. In a statement, the Center for Biological Diversity said, “These rules are little more than a speed bump on the road to climate catastrophe when the president needed to make a U-turn.”
