John OlverToday CWR takes you to a conference at the intersection between climate change and transportation held last week at the University of Massachusetts, Amherst. There, climate scientists, engineers, government officials and activists gathered for a “Climate Change Think Tank” to brainstorm solutions to the problem of transport accounting for some 30 percent of carbon emissions. CWR co-hosts Francesca Rheannon and Bill Baue spoke with Representative John Olver, chair of the House Appropriations Sub-committee on Transportation; Paul Brubaker, head of the US Department of Transportation Research and Innovation Technology Administration; Michael Replogle of Environmental Defense Fund; and Jeff Brown of RideBuzz.org, a regional ride-sharing initiative.
