I started talking about the concept of “sustainable information” here at Grist a couple of months ago, and drew mostly blank stares. It was as if yoking the two words together couldn’t possibly make sense.

I didn’t mean information about sustainability, valuable though that is.

I didn’t mean the sustainable delivery of information — as in, “think of the trees before you print out this e-mail,” or “don’t leave your laptop on its charger round the clock.”
