Well, in communities, the transportation sector represents about a third of all energy and GHG emissions from it. So supporting public transit is a winner in all aspects, if you go through the sustainability principles of financial, economic, and social. That would be a prime focus.
Talking about how to plan cities better to accommodate transit and transit infrastructure is another area. And then the whole idea of vehicles—single-occupancy vehicles—is something that needs to be addressed. Part of the challenge there is measuring it, measuring change from one mode to another.
