Following up Mark Thoma's posts last night (uno and deus), here is an opinion from The Economist:
THE pressure for political action on climate change has never looked stronger. Even George Bush has now joined the leaders of other rich countries in their quest to negotiate a successor regime to the Kyoto protocol, the treaty on curbing greenhouse gases that expires in 2012.
Too bad, then, that politicians seem set on a second-best route to a greener world. That is the path of cap-and-trade, where the quantity of emissions is limited (the cap) and the right to emit is distributed through a system of tradable permits. The original Kyoto treaty set up such a mechanism and its signatories are keen to expand it. The main market-based alternative—a carbon tax—has virtually no political support.
A pity, because most economists agree that carbon taxes are a better way to reduce greenhouse gases than cap-and-trade schemes. That is because taxes deal more efficiently than do permits with the uncertainty surrounding carbon control. ...
And, thank you, thank you, thank you for this bit of truthiness:
Too many politicians pretend that carbon taxes will hurt consumers more than a cap-and-trade scheme, even though the cost of carbon permits will be passed on to consumers just as quickly as a tax.
And, here is what I've been saying (and getting royally ripped for it):
Politicians are heading down the second-best path to combat climate change, but it may be the only one that leads anywhere.
