Carbon accounting

Updated Feb 3, 2025

The Climate Registry Verified Reports

The Climate Registry (TCR) is a nonprofit organization that empowers organizations to do more in the fight against climate change. The MTA is a founding member of TCR, and has voluntarily reported our greenhouse gas emissions with TCR since 2008.

By reporting our emissions, we work to reduce our greenhouse gas emissions and educate the public in the role that mass transit plays in avoiding carbon emissions.

Transit Agency Performance Metric Reports

MTA reporting to TCR also includes metrics on our emissions in relation to ridership and service level. Measuring emissions in relation to service level, such as emissions per passenger mile, allows us to better understand the progress we are making in reducing emissions while better serving our riders.
