Clean M Miles Standar ard W Workshop 2018 B Base Y Year Emission ons I Inventor ory September 25, 2019 1

Purpose • Establish 2018 base year emissions inventory • Discuss data sources, methodology and assumptions • Present preliminary results • Solicit feedback on the assumptions 2

Imp mpor ortan ant N Note • The data analysis and results presented in this workshop are pr prelim limin inary ry • The analysis is conducted using March 2 2019 019 data submittals • Staff has worked closely with TNCs since March to QA/QC the data – updates were incorporated • Preliminary results presented in this workshop may not reflect all of the latest updates 3

Outlin line • Introduction to SB 1014 • Base year inventory methodology • Data description • Assumptions (overlap removal/occupancy/fuel efficiency) • Preliminary Results • Next Steps 4

(Int ntroduc duction) n) (Methodology) (Data Description) (Overlap Removal) (Occupancy) (Fuel Efficiency) (Preliminary Results) Transportation N Network C Companies • California Public Utilities Commission (CPUC) Definition: “ A Transportation Network Company (TNC) is a company or organization operating in California that provides transportation services using an online-enabled platform to connect passengers with drivers using their personal vehicles. ” • In California, the CPUC oversees regulation and permitting of TNCs such as charter-party carriers. There may up to 14 different companies providing services 6

(Int ntroduc duction) n) (Methodology) (Data Description) (Overlap Removal) (Occupancy) (Fuel Efficiency) (Preliminary Results) Princi ciples o of the New R Regulation • TNCs can facilitate state/local governments in meeting emissions reduction goals • Decrease GHG emissions using a compliance metric of annual grams-CO 2 - per-passenger-mile traveled • Transportation decarbonization by increasing zero-emission vehicles • Increase passenger-mile-traveled by increased pooling, active transport (walk/bike), and transit usage • Forward-looking with automated vehicles or new modes that may arise in future • Aligned with other State policies • Maximize transportation access equity 7
