Air Quality Successes – Criteria Pollutants

2

  • 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

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).

ZEVs, coupled with infrastructure that increases climate resiliency Sustainable communities that improve travel choices and reduce VMT

* When accounting for in-state fuel production

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

Transportation Sector: Targets for Pathway to Zero-Carbon

CALIFORNIA AIR RESOURCES BOARD

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

Options to Sequester Carbon (sinks)

10

  • 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

GHG Accounting Practices

13

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
