Clark Williams-Derry of Seattle's Sightline Institute has a nice analysis in their weekly mailing: walking burns about 220 mpg, or 1/12th that of driving.
The claim made awhile back that it's better, GHG-wise, to drive than walk, is bogus. It assumed that human calories were made up of beef, the most GHG-intensive food of all. Of course, those who wanted to use the study for ideological purposes failed to note this inconvenient fact.

Walking's not 220 mpg when you're fetching water to put out a refinery fire. Anyway, we should all be cycling.
