CALSTART launched the Secure Transportation Energy Partnership in June 2005 as a public-private partnership of industry, automotive, business, academia, policy, and nongovernmental professionals to provide guidance and spur specific actions to resolve transportation energy policy issues for California. CalSTEP’s goal is to move beyond political impasse to reach consensus on and implement specific strategies to increase California’s transportation energy efficiency and alternative fuel use, while growing the economy, reducing GHG emissions, and improving the overall welfare of Californians. The CalSTEP effort was made possible by funding from the William and Flora Hewlett Foundation.
