John Tierney discusses an argument that pedicabs may be less environmentally benign than taxis -- and more broadly, that driving may be greener than walking -- when one takes into account the carbon-intensivity of the food the hungry non-drivers are eating. I have my doubts about this. Aren't people in cars also eating an awful lot of carbon-intensive burgers? But whatever. If you want to reduce carbon emissions, tax them; the price system will then sort out these kind of debates very quickly.
Mitch Johnson and I wrote about pedicab politics here.
