Even if the plan were to be adopted, numerous key issues remain to be resolved. For example, as long as the United States remains a party to the WTO, rules and regulations from that body of authority must be observed. “Border carbon adjustments” may not be legally enforceable under international law obligations. They may also not be financially pragmatic given the large volume of imports into the United States. Further, dismantling the federal regulatory regime surrounding power plants may sound good to some voters, but is behind the curve from an international regulatory point of view. The strong dislike of “government” and “regulations” is a very American concept that plays into fears and preferences that do not necessarily correlate well with what is best for the nation’s (and world’s) natural environment, not to mention what is legally and financially possible. There is also evidence that upstream carbon taxes may only have limited effects on consumer behavior (Eric Biber, A Conservative Proposal For a Carbon Tax, Legal Planet, Feb. 15, 2017). Efficiency standards should thus be continued. Other questions abound: Is the carbon tax proposed really high enough to drive the much-needed shift away from a carbon economy to a decarbonized one? What if consumption continues to rise without sufficient renewable energy infrastructure being in place to accommodate the need? What roles do states have in the formulation of a new carbon tax? Would this be legally enforceable, and if so, exactly how would it be implemented? Is it just going to lead to more legal chaos than what we have already seen in the early stages of the new administration?
Such questions and many others remain. It might very well be questionable whether this particular tax proposal will be adopted. However, in such partisan times, it is at least good to see some bipartisan and conservative thinking that might spur further desirable action. Painful as it may be for some to realize, fossil fuels need to be left in the ground. The United States is falling behind the rest of the developed and even parts of the developing world when it comes to climate leadership. Markets want signals of what to expected in the future. The current flip-flopping of American law and policy in this respect is neither beneficial to our nation nor the world. Under the Paris Agreement, the United States agreed to take national action to help avoid a global temperature increase of more than 1.5 to 2° C. We are, from a global perspective, still not on track to meet that goal. A carbon tax, if correctly formulated, implemented, and enforced, could be a step in the right direction for the United States to meet our international obligations. Those are, of course, in the nation’s best interest too.
