Which is greener using a life-cycle analysis: walking to my nearby standard supermarket and buying standardly-commercial produce and meat, or driving the 5.4 miles (10.8 miles round trip) to Green Grocer and buying organic, locally-sourced produce and meat?
I suspect it’s the former.
BUT (a) such a calculation ignores any quality differential between the goods on offer at the two stores, and (b) there’s a Whole Foods 1.4 miles from my house, so I do have a closer option.
