Report on the Implementation of AB 197 Mary D. Nichols, Chairman FEBRUARY 3, 2020 1 CALIFORNIA AIR RESOURCES BOARD
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 NOx Statewide Emissions Trend (tons/day) 4,000 3,000 2,000 1,000 0 STATIONARY AREAWIDE ON-ROAD MOBILE OTHER MOBILE 2
Air Quality Successes – Toxic Air Contaminants Substantial statewide toxic air contaminant reductions have occurred since the early 1990s due to Federal (Clean Air Act), State (Air Toxics Control Measures) and local air district regulations (stationary source reductions).

Transportation Sector: Critical New Paradigm Necessary Aggressive strategies needed to meet National air quality standards, SB 32 GHG requirements, and carbon neutrality in 2045 By 2045: Goal is zero-emission transportation sector through transformative action ZEVs, coupled with Sustainable infrastructure that communities that increases climate improve travel choices resiliency and reduce VMT * When accounting for in-state fuel production 6 CALIFORNIA AIR RESOURCES BOARD
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 • 7 CALIFORNIA AIR RESOURCES BOARD
Transportation Sector: State Actions to Achieve Targets Supporting Requirements Financial Programs • Vehicles • Incentives for • State • Fleets veh’s & chargers investments • SB 375 SCSs • Outreach and education 8 CALIFORNIA AIR RESOURCES BOARD
Carbon Neutrality Sources Sinks Fossil Energy Carbon capture and sequestration Industrial Processes Sources Direct air capture Natural and working = lands Natural and working Sinks lands 9 CALIFORNIA AIR RESOURCES BOARD
Options to Sequester Carbon (sinks) Carbon capture and sequestration (CCS) Capture and store carbon from large emitters (cement, refineries) Direct Air Capture Capture and store carbon from the atmosphere Natural and working lands Emit greenhouse gases, must be managed to emit less and store more carbon over time 10 CALIFORNIA AIR RESOURCES BOARD

GHG Accounting Practices To date Per AB 32, GHG Inventory and GHG targets only include fossil emissions Natural and working lands inventory published separately Looking forward for achieving Carbon Neutrality Per IPCC, impacts from both fossil and natural and working lands emissions matter 13 CALIFORNIA AIR RESOURCES BOARD
