A tool for cities to effectively develop sustainable transportation policies.  In the United States, transportation accounts for nearly 30 percent of all greenhouse gas emissions. As cities attempt to become more sustainable, it is imperative that they curb those emissions. ITDP has defined indicators that are actionable, scalable, and easily understood.

There are many existing indicators of sustainable transit, but many of them are developed using indices that become black boxes, leaving little discernible actions to improve them. Many other existing indicators suffer from an over reliance on complexity, thus requiring a high level of technical knowledge to fully understand and act upon them. In order to avoid those pitfalls, the indicators presented here are easily understood, replicable, and can be tied to policy interventions. We hope this data can be used to advocate for improvements.
