Some Capitol Hill Democrats are pressing President Biden to re-instate Obama-era carbon emissions and mileage rules for passenger cars — and then go much further.

Driving the news: 10 Senate Democrats and dozens of House Democrats, in letters yesterday, call for standards through 2025 that at least match prior rules weakened under President Trump.

  • The letters also urge Biden to set a "more ambitious long-term standard" that will drive down emissions and spur the adoption of electric cars.
  • And they call for setting a date that ends sales of fossil-fuel-powered vehicles, citing 2035 targets in California and Massachusetts.

Why it matters: It shows pressure on Biden to aggressively use existing powers — even as the White House is gearing up to float big new legislative spending proposals.

  • Signers of the letter, led by Massachusetts Sen. Ed Markey, include Sens. Richard Durbin, who is the chamber's number two Democrat, and high-profile progressive Elizabeth Warren.

Pledges to end net emissions by midcentury are now commonplace for big countries and companies, but several looming summits are putting a fresh focus on a much closer horizon.

Driving the news: U.S. officials intend to unveil a 2030 greenhouse gas emissions-cutting target under the Paris deal by April 22 — the date of a big summit Biden is hosting.

CDC: Vaccinated people in COVID hotspots should resume wearing masks

The Centers for Disease Control and Prevention issued updated guidance on Tuesday recommending that vaccinated people wear masks in indoor, public settings if they are in parts of the U.S. with substantial to high transmission, among other circumstances.

Why it matters: The guidance, a reversal from recommendations made two months ago, comes as the Delta variant continues to drive up case rates across the country. Millions of people in the U.S. — either by choice or who are ineligible — remain unvaccinated and at risk of serious infection.
