The Environmental Protection Agency announced Monday a long-expected decision to begin scaling back mileage and carbon emissions rules for cars and light trucks.

Why it matters: The regulations were a pillar of President Obama's climate change agenda. The move may also set up a major battle with California, which currently has authority to maintain tougher mileage rules, and roughly a dozen states that follow California's lead.

Details: The Obama-era rules for model years 2022-2025 would have required a fleet-wide average of over 50 miles per gallon (though it comes out to roughly 36 mpg under real-world conditions).

What they're doing: EPA, in announcing the move, said Administrator Scott Pruitt had determined that "in light of recent data, the current standards are not appropriate and should be revised."

  • The Obama administration "made assumptions about the standards that didn’t comport with reality, and set the standards too high," Pruitt said in a statement.
  • What's next: The EPA and the Transportation Department, which jointly set federal rules, will begin a rule-making process to set "more appropriate" standards, the EPA said. California's waiver to set tougher standards under the Clean Air Act is also being "reexamined."

What they're saying: The Alliance of Automobile Manufacturers, a trade and lobbying group that represents GM, Ford and several other car companies, applauded the move.

  • "We appreciate that the Administration is working to find a way to both increase fuel economy standards and keep new vehicles affordable to more Americans," said spokeswoman. Gloria Bergquist.
  • But environmentalists attacked the decision: “We should be racing toward a cleaner, healthier transportation future. Instead, the Trump administration is steering us onto a dead end road," said Environmental Defense Fund President Fred Krupp.

As the coronavirus poses risks and concerns for the youngest and oldest Americans, the generations in the middle are buckling under the increasing strain of having to take care of both.

Why it matters: People that make up the so-called sandwich generations are typically in their 30s, 40s and 50s, and in their prime working years. The increasing family and financial pressures on these workers means complications for employers, too.
