APTA Sustainability Commitment

The APTA Sustainability Commitment recognizes members who commit to becoming more sustainable in their operations and practices. Through a series of core sustainability principles, the Commitment provides both agency and business members with a common framework that helps define, initiate, and advance sustainability in the public transportation industry.

Currently, we are NOT accepting Transit Agency applications for higher level recognition at the moment.  The Sustainability Commitment Signatories Subcommittee and APTA staff are working on updating the Transit Agency application and will launch the updated application in Summer 2025.

We are accepting Business Members/Non-Operators applications for higher level recognition.  The deadline to apply is May 31, 2025.

Please note all APTA members are still welcome to signing the (entry-level) Commitment Letter to help advance sustainability in the public transit.

How to Participate in the Program

Become a Signatory​

There are no prerequisites for members to sign the commitment.

APTA does ask commitment signatories to report on their sustainability progress through a brief annual status update using a higher-level application template provided by APTA.

Advance Further

APTA members can also obtain further recognition for their actions by applying for higher levels of the commitment, which requires a demonstration of increasingly greater numbers of short- and long-term sustainability achievements and targeted improvements across key indicators. Levels of recognition start at Bronze and advance through Silver, Gold, and finally Platinum.

Signatories can apply for higher recognition or report on their Commitment progress and adherence by using the appropriate application template.
