Paul Krugman: The Big Green Test

Are Republicans willing to settle for second best solutions to climate change?:

The Big Green Test, by Paul Krugman, Commentary, NY Times: On Sunday Henry Paulson, the former Treasury secretary and a lifelong Republican, had an Op-Ed article about climate policy... In the article, he declared that man-made climate change is “the challenge of our time,” and called for a national tax on carbon emissions... Considering the prevalence of climate denial within today’s G.O.P., and the absolute opposition to any kind of tax increase, this was a brave stand to take.
But not nearly brave enough. Emissions taxes are the Economics 101 solution to pollution problems... But that isn’t going to happen in the foreseeable future. ... Yet there are a number of second-best things ... that we’re either doing already or might do soon. ... Let me give some examples of what I’m talking about.
First, consider rules like fuel efficiency standards, or “net metering” mandates requiring that utilities buy back the electricity generated by homeowners’ solar panels. Any economics student can tell you that such rules are inefficient compared with the clean incentives provided by an emissions tax. But we don’t have an emissions tax, and fuel efficiency rules and net metering reduce greenhouse gas emissions. So a question for conservative environmentalists: Do you support the continuation of such mandates, or are you with the business groups (spearheaded by the Koch brothers) campaigning to eliminate them and impose fees on home solar installations?
Second, consider government support for clean energy via subsidies and loan guarantees. ... Are you O.K. with things like loan guarantees for solar plants, even though we know that some loans will go bad, Solyndra-style?
Finally, what about the Environmental Protection Agency’s proposal that it use its regulatory authority to impose large reductions in emissions from power plants? ... Are you willing to support this partial approach? ...
In policy terms, climate action — if it happens at all — will probably look like health reform. That is, it will be an awkward compromise dictated in part by the need to appease special interests... It will be the subject of intense partisanship, relying overwhelmingly on support from just one party, and will be the subject of constant, hysterical attacks. And it will, if we’re lucky, nonetheless do the job.
Did I mention that health reform is clearly working, despite its flaws?
The question for Mr. Paulson and those of similar views is whether they’re willing to go along with that kind of imperfection. If they are, welcome aboard.
