Advanced Clean Transit

This page last reviewed December 4, 2014

Background:


Adopted in 2000, the Fleet Rule for Transit Agencies (Transit Fleet Rule) required reductions in both criteria pollutant emissions and exposure to air contaminants from urban buses and transit fleet vehicles.  The transit fleet rule also established a demonstration and purchase requirement of zero emission technologies for large transit agencies.  Some transit agencies are actively operating and demonstrating zero emission fuel cell and battery electric buses.

The zero emission bus purchase requirement is currently on hold.  Staff is conducting a technical assessment and is planning amendments to the transit fleet rule.  These amendments would further reduce criteria pollutant and greenhouse gas emissions from transit fleet vehicles while continuing to foster zero emission technologies.

The commercialization and widespread adoption of zero and advanced clean emission technologies in the heavy-duty vehicle sector is critical for meeting California's air quality and greenhouse gas emissions reduction goals and transit agencies play an important role in this strategy.

  • This website will be used for all upcoming regulation amendments and notices that apply to transit fleets. It has been reorganized to include all past information about Transit Fleet vehicle requirements including zero emission buses.  We have also combined three listserves for transit fleet vehicles, urban buses and zero emission buses into a single listserve "bus-act".

  • Online Annual Reporting is now available for agencies subject to the Fleet Rule for Transit Agencies. An annual report of a transit agency’s urban buses and transit fleet vehicles as of January 1, 2014 is due to ARB no later than January 31, 2014.
December 3, 2013
  • The Air Resources Board held a workshop on December 3, 2013 at the Metropolitan Transportation Commission. The workshop summarized the four panels (fuel cell electric bus, battery electric bus, ZBus infrastructure, and transit fleets operating ZBuses) from the first workshop on September 17, 2013, and the common themes expressed during the individual stakeholder meetings staff have been conducting. This workshop focused on the potential regulatory concepts and options under consideration for ZBus deployment and included a discussion of a planned broader look at the transit fleet rule that will occur in 2014.
September 17, 2013
  • The Air Resources Board held a workshop on September 17, 2013 at the South Coast Air Quality Management District. The workshop provided an update on ZBus technology, provided an opportunity to comment on suggested program changes that would enhance successful commercialization of ZBuses, and promoted reductions in smog and greenhouse gas emission from transit fleets.
February 5, 2013
  • Online Annual Reporting is now available for agencies subject to the Fleet Rule for Transit Agencies. An annual report of a transit agency’s urban buses and transit fleet vehicles as of January 1, 2013 is due to ARB. The reporting deadline has been extended this year to February 28, 2013.
