Walking vs Driving…

(I am writing this here in my blog and linking to it from Facebook, since at the moment there is no easy way to search and find old stuff on FB — like this will be 6-months from now, and that is annoying!)

Anyway, here goes:

So you might be interested in this FB thread where we discuss the NYTimes article


2. And a friend goes on (via email) to do a little quick research into this (he has a PhD in ecology) and came up with a rough estimate of the carbon footprint of walking vs driving. (This is different than energy cost of course, but related…). What I believe he came up with is that it depends a lot on the diet. If it is heavy on the meat and dairy, then it is a close match carbon wise (which makes sense because “making” meat is very very resource intensive) But if you are eating a plant-based diet, walking wins. But still, not be the “many orders of magnitude” difference one might expect. In other words, it’s certainly quite possible that (say) 4 people on foot or on bikes could be better off carpooling or using a well-used train, etc. But probably not if they are vegan and eating locally sourced, organic/“solar” food. But my friend needs to do more careful number crunching based on some of the research articles on the topic he pulled up.
