California Air Resources Board

Join researchers from the University of California, Davis, or UC Davis, for a webinar exploring the challenges that ride-hailing drivers face with zero-emission vehicle use in California.  

Companies that provide ride-hailing services through an online platform in California are required to comply with the Clean Miles Standard that has a target of 90% electric ride-hailing miles by 2030. These services are operated by Transportation Network Companies, or TNCs, such as Uber and Lyft.

We will explore the research findings on opportunities and challenges ride-hailing drivers face with electric vehicles, and how many TNC drivers use this vehicle technology. The research team will share insights on:

• Current use of electric vehicles by TNC drivers, and how factors such as income, weekly hours of TNC driving, and access to home charging influence these trends
• Key barriers to purchasing and driving electric vehicles that TNC drivers face
• Policy recommendations to help TNC drivers through better education, incentives, and fueling infrastructure

Note on Language Interpretation

Due to budget constraints, we are updating our process for providing language interpretation services (e.g., Spanish, American Sign Language, etc.) at public meetings. In accordance with the Dymally-Alatorre Bilingual Services Act, language interpretation will be provided when at least 5% of anticipated attendees request such services. Registered participants may request services on behalf of others in advance to ensure their needs are being met. You, or someone on your behalf, must request language interpretation services from us at least 14 calendar days before the meeting date.

Background

The Clean Miles Standard Program is a regulation developed by the California Air Resources Board, or CARB, and implemented by the California Public Utilities Commission, or CPUC. It seeks to cut greenhouse gas emissions from passenger ride-hailing services operated by transportation networks companies, called TNCs, such as Uber and Lyft. With CARB’s vehicle emissions expertise and authority and the CPUC’s authority over TNC permits in the state, the Clean Miles Standard is a joint effort to gradually increase zero-emission miles for TNC services and reduce greenhouse gas emissions. The regulation establishes an annual increase in the percent of zero-emission passenger miles traveled and greenhouse gas emission reduction targets that TNCs are required to meet.

The UC Davis research project was designed to give insight on how to get more TNC drivers into electric vehicles.
