Zeroing in on ZEBs, December 2021

The Advanced Technology Transit Bus Index: A North American ZEV Inventory Report

CALSTART’s annual inventory of zero-emission buses provides insight on the current state of ZEBs ahead of $5.25 billion in Infrastructure Investment and Jobs Act funding through the Federal Transit Administration’s Low-No Program. Full-size ZEBs have grown to 3,533 buses nationally, an increase of 27% since the 2020 count. The report notes that most ZEB fleets are small, ten or fewer, so the coming funding will be instrumental in scaling fleets. “Zeroing in on ZEBs” is based on data gathered primarily through local, state, and federal award documents, press releases, phone interviews, and validated via sales information from bus manufacturers. As there is no centralized accounting of ZEBs, and transit agency plans for adoption can shift and/or be delayed, it is important to note that figures contained in the report should not be considered static.
