California is making significant progress on a first-of-its-kind regulation that will reduce GHG emissions from ride-sharing vehicles.

As directed by Senate Bill (SB) 1014, the California Air Resources Board (CARB) is developing the Clean Miles Standard, a first-of-its kind regulation designed to reduce greenhouse gas (GHG) emissions from ride-sharing vehicles and increase the use of zero-emission vehicles (ZEV). The regulation will include two primary requirements related to: (1) increasing the percentage of total miles driven by ride-sharing companies using ZEVs; and (2) reducing GHG emissions per passenger mile traveled. CARB staff rolled out this regulatory concept in a series of public workshops earlier this year, and recently presented updated targets at a workshop on November 19, 2020, along with draft regulatory language released on November 20, 2020. The COVID-19 pandemic has impacted development of the targets, since prior assumptions about ride-sharing are now in flux and the regulatory timeline has been delayed. Here are the top four things to know about this first-in-the-nation regulation.
