In an effort to help reduce the MBTA's carbon footprint, we’re converting our bus fleet to zero-emissions vehicles over the next several decades.

This will require:

  • Gradually replacing our nine bus maintenance facilities—upgrading one facility every 2-3 years
  • Investing an estimated $4.5 billion in modern bus facilities that can support battery electric buses (BEBs)
  • Investing $100 million annually (as facilities become ready), to build our fleet of BEBs

Building a Better T

As part of our $8 billion, 5-year capital investment plan, we're renovating stations, modernizing fare collection systems, upgrading services for our buses, subways, and ferries, and improving the accessibility of the entire system.

Our Plan for a Zero-Emissions Fleet

Our goal is to transition to a zero-emissions fleet that improves service flexibility, capacity, and equity over the next several decades. This will require changes to the system as a whole, which will need to be coordinated to happen in tandem.

To achieve this, our strategy targets three focus areas as part of the overall project. Each of these areas presents its own set of challenges and possible solutions:

What We’re Doing Now

We’re taking a phased approach to purchasing additional vehicles and upgrading the facilities that will support BEBs.

Currently, we’re evaluating opportunities and planning projects that can help us move toward a zero-emissions future faster:
