Assessing State Efforts to Integrate Transportation, Land Use and Climate Change
Rebecca Lewis Rob Zako
Climate change is increasingly recognized as a threat to life on earth. “Continued emissions of greenhouse gases (GHG) will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of GHG emissions.” (IPCC WGI, 2013.)
The transportation sector accounts for almost one-third of all GHG emissions in the United States. Growing Cooler describes GHG emissions from transportation as comprised of a three…

Scooting to a New Era in Active Transportation: Examining the Use and Safety of E-Scooters
Kristina Currans Reid Ewing , Nicole Iroz-Elardo
In recent years, shared electric scooters (e-scooters) have taken cities around the world by storm. But how are people using this new mode of transportation? Seeking to understand the potential impacts of e-scooters on land use, infrastructure and sustainability goals, researchers have some new interesting data to share on e-scooter users, exploring the interplay between demographics, behaviors and trip purposes.
Funded by the National Institute for Transportation and Communities (NITC) and…
