Curbing suburban sprawl will do little to reduce CO2 emissions except for Portland.

[Snowden352]

You know, after rereading the article it occurs to me the reason why Portlanders travel less (and consume less energy) has less to do with whether our city is sprawling but rather where people are traveling to. It seems to me that people are traveling less because their destinations are nearer at hand. I suspect that the causation of the reduction in CO2 is from smarter planning, not density of living.
