As the oldest and the 5th largest transit agency in the US and carrying over 1.3 million passenger trips every day, the MBTA provides a clean and sustainable alternative means of transportation for the region. Without the MBTA, millions of tons of greenhouse gases and other air pollutants would enter our air every year. The MBTA is one of the most environmentally sustainable elements of the metropolitan Boston area.
We strive, however, to do more. The MBTA is committed to a more sustainable environment. One of the end products of a sound transportation system is the positive effect it has on the environment and the local communities. We are continually looking for new ways to reduce the impact of our operations, as well as to find new ways to provide even more sustainable transit trips for our passengers.
The links on the right are some of the projects and initiatives the MBTA is working on to help make Boston and the surrounding communities more sustainable.
