Greening the State Fleet

In recognition of the state's responsibility to minimize its environmental footprint and maximize its role in contributing towards the health of our environment, California State departments are adopting a green way of thinking about their fleet. Under the leadership of Governor Edmund G. Brown Jr., California has undertaken an ambitious effort to promote a reliable, environmentally responsible and cost effective fleet.

Petroleum Reduction

In 2007, legislation was passed that established a goal of reducing or displacing the consumption of petroleum products by the state fleet by 10 percent in 2012 and by 20 percent in 2020 (compared to a 2003 baseline). The state exceed the 2012 goal of a 10 percent reduction and is on pace to exceed the 2020 goal of reducing petroleum consumption by 20 percent.

Fuel Efficient Vehicles

To further reduce petroleum reduction and greenhouse gas (ghg) emissions, in 2012 Governor Brown issued Executive Order (EO) B-16-12 mandating that at least 10 percent of state fleet purchases of light-duty (LD) vehicles are zero emission vehicles (ZEV) by 2015 and 25 percent by 2020. In 2016, Governor Brown issued the 2016 ZEV Action Plan which increased the ZEV percent of state fleet purchases of light duty fleet assets to 50 percent by 2025. Vehicles having special performance requirements necessary for the protection of public safety and welfare are exempted from this mandate.

Since the EO took effect the state has exceeded the annual 10 percent goal and combined with the ZEV purchases made prior to 2015 the state has approved purchase requests for over 700 ZEVs.

Miles Per Gallon

The fuel economy of a vehicle is a critical component towards increasing the state’s fuel overall fuel efficiency and meeting its petroleum reduction goals. Therefore, the state tracks the average miles per gallon (mpg) of its light duty fleet to determine overall efficiency of the state fleet and the corresponding greenhouse gas emissions. The state’s light duty fleet has increased its average MPG by 1.24 percent and reduced its ghg emissions by 5.12 percent on an annual basis since 2013.

Department Contributions

This website tracks the progress towards meeting these goals as well as the results of these policies on fleet vehicle mpg and ghg emissions. The state fleet consists of approximately 50,000 assets split out amount amongst the various state departments. Without departments being proactive in furthering these environmental initiatives, the state would not be able to continue to meet and exceed these goals.
