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.

This year, the Sustainability Commitment Signatories Subcommittee and APTA staff will be working on updating the Transit Agency application. We will improve some technical and procedural aspects of the application, address concerns related to the impacts of COVID-19 and more. As we work on updating the Transit Agency application for a relaunch in 2023, we will NOT be accepting Transit Agency applications in 2023.

Business Members/Non-Operators are welcome to apply for higher level recognitions. The deadline to apply is May 31, 2023.

Lastly, all APTA members are still welcome to sign the Commitment Letter (entry-level) to help advance and promote sustainability in the public transportation industry.

How to Participate in the Program

Become a Signatory

​There are no prerequisites for members to sign the commitment. APTA members can sign onto the APTA Sustainability Commitment at any time and have the flexibility to meet the core principles on their own timing and resource availability.​ To become a signatory, complete and submit the Commitment Form that applies to your organization.

Agencies looking to measure baseline and follow-up indicators may use the Transit Emissions Quantifier Tool to calculate their criteria air pollutant emissions, greenhouse gas emissions and greenhouse gas savings:

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. These brief annual status updates are due to APTA by Friday, June 30, 2023.

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.

Please email Christina Jung at for any questions.

Connect with Other Signatories

Signatories can connect with and learn from other organizations who have signed the Commitment through the APTA Sustainability Commitment Signatories Subcommittee. Membership to this subcommittee is open to all signatories and will allow access to the Subcommittee online community where signatories can participate in discussion pertaining to implementation of the Commitment and share best practices and challenges.
