Not only does traffic contribute to climate change, but it costs the average American $1,377 per year in lost time. We’ll break down the issue, and debate some possible solutions like mass transit renovations, bike sharing, congestion pricing, and smaller market-based mechanisms. We’re joined by Christian Alberga (Williams College), Matt Grottkau (Washington University), and special guest Dr. Cutler Cleveland: Professor of Earth & Environment at Boston University and Associate Director of the BU Institute for Sustainable Energy.
