Environment

The T helps protect our natural resources by providing an alternative to the automobile for over one million people every day and we believe we have an opportunity and a responsibility to do more for the environment.

Working collaboratively with the Environmental Protection Agency grant program, we're working on a first-in-the-nation pilot project to develop a model for locomotive engine pollution control devices and our efforts to develop an Environmental Management System have received national recognition and serve as our platform to identify new opportunities to reduce, reuse and recycle.

We're working on environmentally friendly T-Projects everyday, and making enormous environmental strides-retiring our oldest diesel busses, replacing them with hundreds of new CNG buses and reducing the average age of our busses from 14 to just 4 years.

In 2008, the MBTA commenced a program that lets us monitor the exhaust emissions of our entire bus fleet. Permanent emissions monitoring stations are in operation at the Charlestown and Cabot bus garages. Over each of the last four trimesters, no more than 14 buses have ever failed emissions testing. They were immediately removed from service for repairs. Below are test result summaries for the tests completed to date:

• MBTA Trimester Report Bus Emissions-Testing conducted from 8-26-2008 to 1-22-2009
• MBTA Trimester Report Bus Emissions-Testing conducted from 4-15-2008 to 8-20-2008
• MBTA Trimester Report Bus Emissions-Testing conducted from 12-10-2007 to 4-9-2008
• MBTA Trimester Report Bus Emissions-Testing conducted from 8-13-2007 to 12-6-2007

This website will be updated on a regular basis as new reports are generated. For further information of the MBTA's Bus Emissions Monitoring Program, see attached document.
