The Green New Deal that Democrats unveiled last week is actually two deals: one to combat global warming, another to create millions of well-paid jobs for targeted groups.
Individually, both goals have their merits. But by combining them, the Green New Deal promises to make climate mitigation both absurdly expensive and deeply partisan and is thus more likely to set back than advance the climate cause.
The premise behind the Green New Deal is right. While the world may not spontaneously combust in 10 years, global carbon-dioxide emissions need to start dropping soon, by a lot, to keep temperatures from rising more than 1.5 degrees Celsius from 1800s levels, according to the Intergovernmental Panel on Climate Change. Increases beyond that raise the probability of extreme weather, deadly heat and rising sea levels.
The Green New Deal’s plan to upgrade every building in the U.S. to “maximum energy efficiency” is even more questionable. A study by Meredith Fowlie, Michael Greenstone and Catherine Wolfram in the Quarterly Journal of Economics found the federal government paid an average of $4,585 each to weatherize homes in Michigan. Extrapolate that to 95 million homes nationwide, and the bill tops $400 billion. The cost of avoided carbon dioxide: up to $285 per ton.
To understand how high $83 to $285 per ton of carbon dioxide is, consider that Barack Obama’s economists put the economic harm of a ton of CO 2 at $50. Or that you can pay a power producer just $6 to reduce emissions by one ton in New England, $15 in California, and $25 in the European Union, based on emission permit prices in those jurisdictions, notes Mr. Greenstone, an economist at the University of Chicago.
