In our first annual U.S. Transportation Climate Impact Index, we rank the country’s 100 most populous metro areas. Our data scientists analyzed several carbon-related transportation factors, including VMT, bicycle and pedestrian commutes, and circuity.

How well is your region doing?

Rather than study traditional design-based measures (like, how many miles of bike paths exist) our list draws on performance-based metrics (how much actual bike commuting people do). Big Data captures real-life mobility behavior. In other words, you may have built it, but did they come?

Our fresh perspective highlights the tight connection between transportation and urban planning, and offers insights into how cities can offset their carbon output.
