SamTrans is committed to supporting a more sustainable San Mateo County.

SamTrans promotes sustainability by providing affordable, accessible, environmentally friendly mobility options to move people where they live, work and play. Its Sustainability Program regularly evaluates the agency’s operational impacts on communities and the environment, and finds ways to lessen those impacts. The agency also encourages environmental stewardship in SamTrans’ partners, customers and employees.

Sustainability Benefits of Riding Public Transit
Customers that ride SamTrans promote sustainability in many ways that benefit the community:
• Reducing fuel consumption
• Saving households money[1]
• Mitigating traffic congestion
• Reducing greenhouse gas emissions and related climate change impacts
• Improving regional air quality

SamTrans’ Commute Calculator helps estimate how much money customers save by taking SamTrans instead of driving. A Carbon Savings Calculator estimates how taking transit can reduce your carbon footprint.

[1] An average 20-mile trip by car can cost $10-15 (AAA 2014 “Your Driving Costs”)

APTA-Sustainability-Bronze-Recognition-logo Sustainability Program Framework
Sustainability is a key component of the San Mateo County Transit District’s vision and Strategic Plan. The District’s Sustainability Policy summarizes our commitment to incorporating sustainability into standard operating procedures and long-term decision-making.


The District is a strong supporter of American Public Transportation Association’s Sustainability Program and participates in the annual Sustainability & Public Transportation Workshop as well as APTA’s Sustainability committees. In 2010, the District became a founding signatory to the APTA Sustainability Commitment. In 2011, the District received the APTA Sustainability Commitment Bronze Recognition for its SamTrans bus service. As of April 2015, of the 113 signatories to the sustainability commitment, SamTrans is one of only 24 organizations to have achieved higher-level recognition.
