The Senate this week is debating a bill that attempts to mitigate global warming through a “cap and trade” permitting system that over time imposes severe constraints on the emissions of greenhouse gases. By 2050, the bill limits U.S. greenhouse gas emissions to 70 percent below the 2005 level. The bill, sponsored by senators Joe Lieberman (D-Conn.) and John Warner (R-Va.), allocates or auctions emission allowances to power plants, refineries, factories, and other covered facilities. Companies that succeed in reducing their emissions below the required level can sell their emission allowances to other companies.
In a recent Heritage Foundation Backgrounder, Ben Lieberman identifies the significant costs and minimal benefits of the bill.
• GDP hit:
It is hard to think of any economic activity that does not involve energy, and there is not one that would not be made more expensive by Lieberman–Warner. No matter how measured, the impacts of the bill on the American economy overall as well as on individuals and households would be substantial and hardly different from a massive energy tax.
The impact on the overall economy is reflected in cumulative gross domestic product (GDP) losses estimated at $1.7 trillion (with generous assumptions) to $4.8 trillion (with more realistic assumptions) by 2030. The single-year GDP losses would range from $111 billion to $436 billion, or $949 to $3,726 per household for each of the nation’s 117 million households. … Thus, the annual costs of the Climate Security Act would significantly exceed the Department of Homeland Security’s 2007 expenditures of $43 billion and could also exceed the $155 billion spent on highways at all levels of government in 2005.
After-tax incomes decline by $47 billion to $120 billion in 2015, or $402 to $1,026 per household. Declines in consumption average $54 billion to $113 billion over the forecast period, or $462 to $966 per household annually.
• Job losses:
America’s Climate Security Act would spark a temporary increase in employment in the first few years as regulated companies invest heavily to comply. After that, however, the bill causes job losses that are expected to exceed 500,000 before 2030 even under the most optimistic assumptions. … It should be noted that these are net job losses after the jobs created by the Climate Security Act are taken into account. Particularly hard hit are manufacturing jobs as higher energy costs dampen several energy-intensive sectors. … Some of the lost jobs will be destroyed entirely, while others will be outsourced to nations like China that are unlikely to place similar, if any, constraints on their emissions.
• Higher energy prices (amounting to a regressive excise tax) for consumers:
While the Lieberman–Warner bill lowers many household incomes, it raises the cost of living, particularly by raising energy prices. To meet the bill’s targets, consumer energy demand must be driven down, which is achieved through higher prices. The price per gallon of gasoline is expected to increase by at least 29 percent by 2030: about $1.10 more per gallon based on current prices. By 2030, average household electricity costs are also expected to increase by $647 annually, and natural gas is expected to increase by $303.
• Little benefit: The bill imposes constraints on the U.S. economy as a solution to what is posited as a global problem, even though China, India, and other developing countries has shown no willingness to risk economic growth in order to reduce greenhouse gas emissions. But even if all nations abided by the limits on greenhouse gas emissions in the Kyoto protocol, there would be only a .07 degree Celsius reduction in world temperatures, “an amount too small even to verify and one for which any resulting benefits would be inconsequential.” Lieberman says: “It is unlikely that Lieberman-Warner would be much different.”
Cato’s Pat Michaels calculates:
Assume that all the nations of the world fulfill their obligations under the Kyoto Protocol (they won’t!), which reduces global emissions about 5% below 1990 levels. That results in a “savings” of global warming of 0.07 degrees Celsius by 2050—an amount too small to measure, as global temperatures vary on their own about twice that much from year-to-year.
Now add in Lieberman-Warner. Say the U.S. actually does what the law says, though no one knows how to. The result is an additional 0.013 degrees (C) of “prevented” warming.
In a recent National Review article, Heritage’s Michael Franc notes another set of problems with the bill: As a tax on energy, it is a massive revenue raiser, and thus paves the way for an ever larger federal government. The bill will bring in an extra $1.2 trillion over the first seven years of the “cap and trade” system. Sen. Barbara Boxer, recognizing that the bill’s prospective damage to the economy will be a significant political hurdle, has introduced a substitute bill that seeks to buy political support for the bill by dedicating some of the new revenue stream to things like worker retraining and adjustment. Franc writes:
Liberals instinctively want their global-warming regime to resemble the tax code. Saturate it with special-interest provisions to protect favored constituencies from pain. Place a disproportionate share of the burden on the privileged few. If the wealthiest 1 percent of taxpayers can pay 40 percent of all income-tax revenue, why can’t they also cough up 40 percent of all CO2-emission reductions? And, if the bottom half of taxpayers only have to pay 3 percent of taxes, then why can’t we exempt them from the economic pain and dislocations inherent in any cap-and-trade scheme?
But this global-warming free lunch can’t be subsidized away. Why not? That unforgiving cap on overall carbon emissions in Lieberman-Warner means if you alleviate the burden on one favored group, you necessarily have to increase it on others. The reductions ultimately have to come from somewhere. We must comply with that cap.
Industries that don’t lobby successfully for a subsidy will incur the most concentrated economic harm. And, of course, they will pass these costs on to all those who thought they had hired really good lobbyists to protect their interests.
