More from Sustainability

Learn more about sustainability programs at the MBTA.

As one of the largest landowners in the Commonwealth of Massachusetts, the MBTA has a responsibility to support infrastructure that improves the health of the communities we serve. This includes, but is not limited to, programs that promote recreational land use, water quality improvements, and wildlife protection.


The MBTA works with the Division of Fish and Game (DFG) to maintain safe crossing areas for wildlife. These well-lit crossings are located near known animal habitats as well as locations safe for animals to live. They were first installed to help turtles cross railways, and since then, studies have shown that a variety of wildlife, including foxes and rabbits, use them too.

Stormwater Management

Some MBTA stations and carhouses are located near bodies of water. Stormwater and runoff pollution prevention is an essential part of planning, construction, and use of these facilities. Download the stormwater pollution prevention plans (SWPPP) associated with each project below.

Vegetation Management

Federal and state laws require transit systems to control vegetation that could interfere with rail safety. The MBTA’s 4 subway lines travel along more than 70 miles in 11 communities in the Boston area, and much of this service area requires preventative maintenance to control vegetation. 

Learn more about the MBTA’s vegetation management strategy and get details about the herbicides we use in the documents below.

Environmental Clean Up

Readville Yard 5

The MBTA inherited the 45-acre land parcel now known as the Readville Yard 5 facility in the 1970s. The previous owners used the land for vehicle maintenance and left behind debris, refuse, and contaminated land that became a concern for the T and surrounding communities. 

Ultimately, cleanup included the removal of 17,840 tons of contaminated soil, 11.2 tons of trash, 1,009 tons of concrete and metals, and 74 tons of railroad ties. 

The MBTA uses a small part of the site for rail purposes, another portion is a large solar farm, and another portion is being considered for the development of new commercial buildings.

Scituate Salt Marsh

In the early 2000s, the restoration of service on the Greenbush Line raised environmental concerns for the surrounding communities.

A 4.74-acre salt marsh, located in Scituate, mitigated the environmental impact of the project. Since it was first opened, the land has been colonized by salt marsh species, and the pathway adjacent to the marsh provides beautiful views of the North River and the nearby areas.
