Deploying electric vehicles instead of gasoline-powered models for services like Uber and Lyft provides outsized climate benefits compared to emissions cuts from electric vehicles for only personal use, per a peer-reviewed study in Nature Energy.

Why it matters: The analysis, based on California data, follows explosive growth in ride-hailing in recent years — and evidence that it's cannibalizing more climate-friendly mass transit.

  • The study is based on data provided by Uber and Lyft as well as charging providers, which together provide a detailed look at how the limited number of electric vehicles in the ride-hailing fleets actually operate in the real world.

The big picture: "[T]he potential environmental and emission reduction benefits are approximately three times higher for electric vehicles being used in ride-hailing compared with those of regular vehicle usage in California," finds the paper by Alan Jenn. He's with the Institute of Transportation Studies at the University of California, Davis.

How it works: There's a couple of big reasons expanding what's now a small number of electric vehicles in ride-sharing is helpful from an emissions standpoint.

  • One is that ride-hailing vehicles log lots of miles, so the comparative advantage of a zero-emissions vehicle becomes proportionately higher.
  • And the charging profile of the ride-hailing vehicle is different than cars used only for personal needs. The ride-hailing cars tend to charge during the day when solar penetration on the grid is higher.

Where it stands: The paper comes as California regulators and ride-hailing companies are seeking to increase the amount of electric vehicles used in the industry.

  • Most recently, Lyft announced a goal in June to have 100% electric vehicles (or other zero-emissions models) on its platform by 2030.
  • But the plan assumes significant help from state and federal policymakers.
  • Electric vehicle adoption in ride-hailing is challenging because the vast majority of vehicles are driver-owned and electric vehicles currently have higher up-front costs.

California labor commissioner sues Uber and Lyft

California's Labor Commission has filed lawsuits against Uber and Lyft, accusing them of "committing wage theft by misclassifying employees as independent contractors." The suit will replace individual claims that drivers have filed.

Why it matters: This is the latest move by California officials seeking to force the companies to reclassify their drivers from independent contractors to employees following a new law that went into effect in January.

Elliott Abrams to replace Brian Hook as Trump's Iran envoy

President Trump's Iran envoy, Brian Hook, is stepping down, Secretary of State Mike Pompeo confirmed Thursday. He will be replaced with Venezuela envoy Elliott Abrams, a noted Iran hawk who will serve in both roles.

Why it matters: Hook had been tasked with executing Trump's "maximum pressure" policy toward Iran, working closely with Pompeo. That strategy has deepened tensions and thus far failed to force Iran back to the negotiating table, as Trump had hoped.

Ohio Gov. Mike DeWine (R) has tested positive for COVID-19 and plans to quarantine at his home for the next 14 days, his office announced Thursday. He currently has no symptoms.

Why it matters: The 73-year-old DeWine was set to meet President Trump Thursday on the tarmac at an airport in Cleveland and was tested as part of standard protocol. He is the second governor known to have contracted the coronavirus, after Oklahoma Gov. Kevin Stitt (R).
