Demystifying the ?Absolute Zero? concept

GreenBiz

The nuances of all the various adjectives and descriptors that are used to describe climate action — from "science-based" to "net zero" to "carbon negative" — are enough to make heads spin, especially for those who spend their professional lives worrying about how to communicate these concepts. Offsetting versus insetting.
