The prominent environmental policy veteran Carol Browner is joining Lime as an adviser as the dockless bike and scooter company ramps up its focus on sustainability and climate change.

Why it matters: Browner is a well-connected figure in green circles after heading the EPA under President Clinton and serving as the White House "climate czar" under President Obama. She arrives as the industry is making the case for its environmental bona fides and seeking to improve its initially rocky relationships with cities and other layers of government.

The big picture: Brown's arrival as sustainability adviser comes 2 months after Lime pledged that all rides on its electric scooters and bikes will be "carbon neutral" — the first part of a wider environmental initiative called "Lime Green."

Browner tells Axios that she's excited about the emissions-cutting role that bikes and scooters can play, noting at one point that the number of car trips of a mile or less is "amazing."

  • "It's exciting to be working directly on how to reduce carbon emissions. Transportation is a significant piece of the puzzle," she says.
  • “It’s not just carbon dioxide benefits. It’s conventional pollution benefits,” Browner adds.

Details: Browner is already drawing on her experience as an environmental regulator to think about the role that bikes and scooters can play.

  • For instance, she says it's worth looking at how states can incorporate them into EPA-mandated plans for meeting air quality standards for pollutants like sulfur dioxide and soot.
  • “It’s not inconceivable that you would give credit for alternative forms of transportation that don’t produce pollution.”

One fun thing: Browner admits that she'll be playing some catch-up, telling Axios: “I am waiting for one of my millennial children to give me a lesson on how to use the scooter.”

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.

U.S. vs. Google — the siege begins

The Justice Department fired the starter pistol on what's likely to be a years-long legal siege of Big Tech by the U.S. government when it filed a major antitrust suit Tuesday against Google.

The big picture: Once a generation, it seems, federal regulators decide to take on a dominant tech company. Two decades ago, Microsoft was the target; two decades before that, IBM.

Why the stimulus delay isn't a crisis (yet)

If the impasse between House Speaker Nancy Pelosi and the White House on a new stimulus deal is supposed to be a crisis, you wouldn't know it from the stock market, where prices continue to rise.

  • That's been in no small part because U.S. economic data has held up remarkably well in recent months thanks to the $2 trillion CARES Act and Americans' unusual ability to save during the crisis.
