Air Quality Successes ? Criteria Pollutants
? NOx emissions have steadily declined since 1970s ? Reductions are due to improvements in vehicle efficiency and
advancements in stationary source engine and stack emission control technologies

Transportation Sector: Targets for Pathway to Zero-Carbon
Widespread Electrification
? By 2035: 100% new car sales are ZEVs; All school buses, marine port & airport equipment are ZEVs
? By 2045: All passenger vehicles on the road are ZEVs
Increased Transportation Options to Reduce VMT
? By 2035: Reduce vehicle miles traveled per capita by 25% ? By 2045: High-quality, efficient travel options for all Californians

Light-Duty Vehicle Regulations that Impact ZEVs
Advanced Clean Cars II
? Goal:
Reduce GHG emissions and increase ZEVs from automakers beyond 2025
Reduce NOx emissions to help attain Ozone Standards in 2031 in South Coast
? Method: Increased requirements for ZEVs, and lowered GHG and criteria fleet requirements
Clean Miles Standard
? Goal:
Reduce emissions, promote ZEVs, and reduce VMT within ride-hailing fleets
? Method: Set annual GHG targets and minimum required electric VMT
