Transportation

VMT Per Capita Compared to Population

Growth Relative to Base Year

Why it Matters

  • Vehicle miles traveled (VMT) is an important metric to track as it has large implications for California’s greenhouse gas emissions.
  • As VMT grows, increased use of clean vehicles and fuels are critical for reducing emissions of greenhouse gasses and smog-forming pollutants.
  • Reducing the growth in vehicle miles traveled is necessary to meet the State’s greenhouse gas emission goals.

CA Greenhouse Gas Inventory 2014

By Sector and Activity (2016 Edition)

Why it Matters

  • Transportation is the largest source of GHG emissions in California, most of which comes from passenger vehicles
  • However, when you consider emissions associated with the extraction and refining of transportation fuels, the share of the GHG emission inventory linked to transportation increased.
  • Over 51% of industrial sector emissions are attributable to oil and gas extraction, petroleum refining and hydrogen production, and pipelines.
  • When taking into account industrial and tailpipe emissions, transportation accounts for nearly half of the State’s greenhouse gas emissions.

Change in Active Transportation

Relative to 2002

Why it Matters

  • Active transportation includes walking, biking, and other non-motorized modes of travel.
  • In 2013, California established the Active Transportation Program within the California Department of Transportation (Caltrans).
  • The goals of the Active Transportation Program include: Increasing the proportion of trips accomplished by biking and walking, improving safety for non-motorized travelers, reducing greenhouse gas emissions, improving public health, and ensuring benefits to disadvantaged communities.
  • Since 2002, the number of miles traveled by biking and walking has increased.
  • In addition to reducing greenhouse gas emissions, increases in active transportation result in large benefits to public health
