Cities and climate change researchers can’t stop talking about StreetLight Data’s 2019 U.S. Transportation Climate Impact Index. The study ranks the country’s top 200 metro areas on six key transportation impact factors affecting climate change: Vehicle Miles Traveled (VMT), bicycle commuting miles, pedestrian commuting miles, transit use, population density, and trip circuity.

Watch the webinar to hear StreetLight CEO Laura Schewel explain

- Why we chose these particular transportation impact factors
- How we weighted them
- How cities can use big data metrics like these to lower their emissions
