Hank Paulson endorses a carbon tax. But is he right this time?
The climate change industry always needs a fresh angle, and the latest is that carbon emissions are an economic threat akin to mortgage-backed securities before the financial panic. The analogy comes from Hank Paulson —and if he has spotted a bubble this time, we guess one out of two is an improvement on zero out of one.
With the travelling billionaire wilburys of Tom Steyer and Michael Bloomberg, the former Treasury Secretary put out a 197-page study last week that predicts the costs of a warming catastrophe. Their “Risky Business” project is meant to awaken the green conscience of business leaders, and President Obama’s endorsement was inevitable: Even George W. Bush’s money man agrees . . .
The report reads like a prospectus, except with years of “investments” in fossil fuels returning damage across industries and regions. The authors estimate storms along the eastern seaboard and Gulf of Mexico will cost $2 billion to $3.5 billion more, while they also look at so-called “tail risks,” or worst-case crises with a 1-in-100 chance of happening: New York City could be 6.8 feet underwater by century’s end, crops could wither in heat waves by 42%, and so forth.
Mr. Paulson’s particular contribution has been to summon the apparitions of the 2008 crash. He recently mused that his career in business and government taught him that “it is time to act before problems become too big to manage.” The “climate bubble,” as he puts it, is like the housing excesses that built up in the global financial markets and could lead to contagion.
CEOs might reasonably question Mr. Paulson’s skills as a risk manager, given that as Treasury chief he went along with the Beltway flow and assured the public that Fannie and Freddie were in good shape until it was too late. And are there even amateur investors who are unaware that climate change is a matter of some political interest? Many public companies already embed a proxy cost of carbon when they invest and disclose material risks that climate change may or may not pose to their balance sheets.
