Krugman on cap-and-tradePaul Krugman at his blog gives an accessible defense of the "cap and trade" incentive system to reduce greenhouses gases in Unhelpful Hansen 12/07/09. The Hansen of the title is James Hansen (not neocon war zealot Victor Davis Hanson), who Krugman praises as "a great climate scientist", noting, "I take what he says about coal, in particular, very seriously." But Hansen argues that cap-and-trade is ineffective, and Krugman explains why he disagrees with that view. An excerpt:
... the fact is that cap and trade works. Hansen admits that the sulfur dioxide cap has reduced pollution, but argues that it didn’t do enough; well, it did as much as it was designed to do. If Hansen thinks it should have done more, he should be campaigning for a lower cap, not trashing the whole program.Tags: cap-and-trade, paul krugman
