Advanced Clean Transit

This page last reviewed August 15, 2016


Adopted in 2000, the existing rule, the Fleet Rule for Transit Agencies, requires 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.  ARB is currently working on refreshing the rule, Advanced Clean Transit (ACT) rule, by actively engaging stakeholders such as public transit agencies, bus manufacturers, technology providers, and other stakeholders.  The transformation of the existing transit fleet is an important first step in ARB's strategy to accelerate the use of advanced technologies in the heavy duty vehicles to meet air quality, climate and public health goals.  

Staff is currently developing a proposal to further reduce emissions from the conventional bus fleet by requiring use of renewable fuels and the cleanest available engines and phasing-in zero emission bus purchases.   As fleets become familiar with zero emission bus technology, and technology evolves, purchase requirements would increase with the goal of transforming the statewide transit bus fleet by 2040. The proposed amendments would also include flexibility options for fleets to work together to pool requirements or to develop regional plans to meet the same goals.

  • A tool for estimating electricity costs for battery electric bus (BEB) deployments is now available.  The Battery Electric Bus Charging Cost Calculator, first mentioned at the April 8 utility workgroup meeting, estimates monthly electricity costs for deployments of BEBs that are charged at the depot or on-route.  The spreadsheet allows numerous variables to be factored in for the nine utilities included in the tool.  A detailed description and instructions for the tool are included in the file.
