Irene and I have joked about those carbon offset bumper stickers being a form of climate absolution. That said, to some limited extent the idea makes sense, though it may give people the wrong idea of how cheap it would be to solve the climate issue. The problem is that the marginal cost per unit of remediation goes up with volume, which is one of the ways a closed environment confounds the open-system thinking of economists.
Anyway, it appears that one entire nation is committed to this form of absolution. Guess which country is absolved of its sins?
