This week, the House of Representatives will take up H.Con.Res.89, opposing carbon taxes in the United States, submitted by Congressman Scalise (R-LA). We previously blogged about the Senate version of this resolution, arguing that one could agree with many of the individual findings in the resolution and still find reason to support a carbon tax.

Last week, the Niskanen Center, joined by a group of conservative and libertarian colleagues, sent the following letter to Members of Congress responding to this resolution and making the affirmative case for a carbon tax as a least-cost mechanism for reducing greenhouse gas emissions and reducing climate risk.

Dear Representative,

Later this week Congress will take up a resolution sponsored by Congressman Scalise (R-LA1) that expresses the sense of Congress that a carbon tax would be detrimental to the economy of the United States. We are concerned that this resolution offers a limited perspective on carbon taxes and is blind to the potential benefits of market-based climate policy. Legislation that incorporates a carbon tax could include regulatory and tax reforms to make the United States economy more competitive, innovative, and robust, benefiting both present and future generations.

We recognize that a carbon tax, like any tax, will impose economic costs. But climate change is also imposing economic costs. This resolution falls short by recognizing the cost of action without considering the cost of staying on our present policy course. There are, of course, uncertainties about the future cost of climate change and, likewise, the cost associated with a carbon tax (much would depend on program design and the pace and nature of technological progress).1 The need for action, however, is clear. A recent survey of economists who publish in leading peer-reviewed journals on these matters found that 93% believe that a meaningful policy response to climate change is warranted.2

The least burdensome, most straightforward, and most market-friendly means of addressing climate change is to price the risks imposed by greenhouse gas emissions via a tax. This would harness price signals, rather than regulations, to guide market response. That is why carbon pricing has the support of free market economists,3 a majority of the global business community,4 and a large number of the largest multinational private oil and gas companies in the world (the corporate entities among the most directly affected by climate policy).5

In reaching a conclusion, this resolution neglects the fact that the United States already has a multiplicity of carbon taxes. They are imposed, however, via dozens of federal and state regulations, are invisible to consumers, unevenly imposed across industrial sectors, unnecessarily costly, and growing in size and scope.6 The policy choice is not if we should price carbon emissions, but how.

Unfortunately, this resolution also fails to differentiate between proposals that would impose carbon taxes on top of existing regulations (chiefly the Obama Administration’s Clean Power Plan), and proposals that would impose carbon taxes in place of those existing regulations.7 Conservatives and free market advocates should embrace the latter, regardless of how they view climate risks.

An economy-wide carbon tax that replaces existing regulatory interventions could reduce the cost of climate policy and deregulate the economy. It could also provide revenue to support pro-growth tax reform, including corporate income or payroll tax cuts, which could dramatically reduce overall costs on the economy.8 Revenues could be applied to compensate those who suffer the most from higher energy costs; the poor, the elderly, and individuals and families living on fixed incomes.9

Unfortunately, none of those options are presently available because Members of Congress have neglected opportunities to design and debate market-friendly climate policies in legislation. Instead, they have yielded authority in climate policy design to the Executive Branch. By discouraging a long-overdue discussion about sensible carbon pricing, this resolution frustrates the development of better policy.
