The San Joaquin Joint Powers Authority (SJJPA) has committed to achieving near zero greenhouse gas emissions in its locomotive and Thruway bus fleet by 2030 through use of 100% renewable diesel fuel. SJJPA is also committed to working with the State of California to achieve a zero-emission locomotive and Thruway bus fleet by 2035. This Climate Action Plan (CAP) Framework is a precursor to a more complete CAP and presents the initial analysis supporting the agency’s commitment and outlines the next steps for CAP development following identification of additional funding sources.
