ZEBTA
In collaboration with Stanford University's Precourt Institute for Energy, AC Transit developed our groundbreaking Zero Emission Transit Bus Technology Analysis (ZETBTA). These reports represent meaningful analysis of the various bus technologies which AC Transit operates. This analysis is the first ever true, side-by-side evaluation of zero emission bus technologies operated by the same agency, in the same service environment, with ZEBs from the same bus manufacturer, and compared to conventional fleets.
Read the report to learn:
- How AC Transit has updated the ZEB Transition Plan to meet the requirements set forth in the Bipartisan Infrastructure Law
- How AC Transit’s workforce has achieved over 25,000 hours of instruction on ZEB technology and is moving forward with testing virtual and augmented reality to further enhance training
- How each of the four volumes of the study compare, summarizing the past two years of data, including fleet performance
The 2024 ZEBTA Report was published on July 22, 2025.
