Proposition 30 would provide money to aid California’s transition to electric vehicles.

Despite the Bay Area’s eco-friendly reputation, donors from the region are bankrolling the campaign against Proposition 30, which would raise taxes on the wealthiest Californians to speed up the state’s transition to electric cars.

Opponents of the measure have raised more than $14 million so far. They include some of San Francisco and Silicon Valley’s most well-known billionaires, venture capitalists, CEOs and developers.

Supporters of the initiative have put those deep-pocketed opponents — who include Netflix CEO Reed Hastings and venture capitalist Michael Moritz —in the spotlight in recent weeks. They launched a website to criticize anti-Prop. 30 donors, as well as a mobile billboard campaign. The billboard displays a man in a gas mask transposed against the image of burning forests, and has been seen rolling through the streets of the Financial District and other affluent areas of the city in recent weeks.

“The billionaires opposing Prop. 30 can breathe easy,” the Yes on 30 campaign declares its ads. “But 38 million Californians can’t.”

Prop. 30 on the Nov. 8 ballot would increase California’s income-tax rate by 1.75% for people earning more than $2 million per year. Most of the money, 80%, would be dedicated to rebates and infrastructure for electric vehicles. The remaining 20% would be earmarked for wildfire prevention and firefighting.

But opponents of the measure have been far out-raised by its backers — actually, one very big supporter.

Lyft and Uber must comply with a California requirement that their fleets use zero-emissions vehicles for 90% of the miles their drivers travel by 2030.

Lyft, the ride-hailing company, has spent more than $45.3 million to back Prop. 30, though a host of environmental groups have led the public campaign. If the measure is approved, it could provide the company with a major pot of funding to help its drivers buy electric cars.

Ride-hailing platforms, such as Lyft and Uber, must comply with a state mandate that requires their fleets to use zero-emissions vehicles for 90% of the miles their drivers travel by 2030.

Gov. Gavin Newsom, despite championing the state’s aggressive electric-car regulations, has been the face of the campaign opposing Prop. 30. He has called the measure a “cynical scheme” by Lyft to grab taxpayer funding. Other major opponents of the measure include Govern California, a powerful network of wealthy donors, and the California Teachers Association, which warns it could suck up money the state might need for schools.

“Don’t be fooled,” Newsom said in a recent TV ad. “Put simply: Prop. 30 is a Trojan Horse that puts corporate welfare above the fiscal welfare of our entire state.”

Supporters of Prop. 30 have punched back, suggesting Newsom is looking out for wealthy donor friends. But who exactly is backing the effort to defeat the measure? Below are five of the largest donors to the opposition campaign.

None of the donors responded to a request for comment, aside from Moritz, who replied with a YouTube link to Newsom’s ad.
