Constitutional Issues in Cap and Trade: New Light from an Unexpected Source

At the end of April, the Supreme Court decided an obscure case called McBurney v. Young about state public records law.  Quite unexpectedly, the court’s opinion turns out to be good news for state environmental regulators.  In particular, it clarifies how cap and trade relates to what lawyers call the dormant commerce clause — a doctrine that prevents states from creating barriers to interstate commerce. McBurney may also have some implications for renewable portfolio standards, although that’s less clear.

The case involved a Virginia law that allowed state residents, but not non-residents, to make FOIA requests for state documents.  One issue was whether the law discriminated against interstate commerce.  Here’s what the Court had to say about that issue:

We have held that a State does not violate the dormant Commerce Clause when, having created a market through a state program, it “limits benefits generated by [that] state program to those who fund the state treasury and whom the State was created to serve.”  “Such policies, while perhaps ‘protectionist’ in a loose sense, reflect the essential and patently unobjectionable purpose of state government—to serve the citizens of the State.” [citations omitted]

This logic applies equally to cap-and-trade systems.  Emissions trading is the market for a product (emissions allowances) which the state has created, so it is free to limit participation in the market to in-state firms under the reasoning of McBurney. The same reasoning seems to apply to offset credits.

Of course, language in a single Supreme Court case isn’t necessarily decisive, since future cases have to be considered in light of other existing precedents, and differences in facts matter too.  But McBurney is definitely a helpful precedent for defending cap and trade.

What about renewable portfolio standards that give credit only for locally generated power?  This is a trickier question.  To the extent states restrict trading between utilities in renewable energy credits once they’re created, McBurney seems to apply.  But more serious problem involves restrictions on how those credits are generated by purchasing power for renewable sources.  Some state plans might be considered discriminatory because they in effect exclude out-of-state renewables.  McBurney may or may not be helpful here.

Although you could view renewable portfolio credits as a market created by the state, the state doesn’t create the interstate electricity market. There’s some other language in McBurney, however, that might help the state in defending the restriction to in-state generators:

The ‘common thread’ among those cases in which the Court has found a dormant Commerce Clause violation is that ‘the State interfered with the natural functioning of the interstate market either through prohibition or through burdensome regulation.’

If we consider the “natural functioning of the interstate market” to be the electricity market’s functioning without the state’s renewable portfolio standard, it’s not clear that out-of-state renewable providers would even be participating in the state’s naturally functioning electricity market. So unless they can show that the state’s program deprives them of sales they would make in the absence of the renewable portfolio standard, McBurney suggests that they wouldn’t have a discrimination claim. But it’s not clear whether a court would accept this argument. A judge might consider the argument just too subtle to worry about, in the face of the common sense point that in-state renewables are being treated more favorably than out-of-state renewables.  On balance, McBurney seems to help the state in this situation, but it’s not clear how much.

  1. Cap and trade is slowly declining and will disappear altogether as anxiety over climate change continues to subside. Global warming was an interesting episode in the environmental movement but now its over. Time to move on. Have a good day and be happy.

  2. Dan,

    This is an interesting argument. The cases the court cites to in its brief foray into DCC doctrine and creation of a market are ones I hadn’t looked at before. So thank you. Also, your RPS analysis above reminds me very much of the appellate panel decision in the recent Ontario FIT case. Check out the part of the opinion where the court discusses definition of a subsidy under the SCM agreement (117-140).

    A few questions:

    Does the state confer a benefit when it includes a source of emissions in a cap-and-trade program?

    Should it matter for the analysis if the market upon which the incidental effects are imposed (wholesale electricity) is not the one that the state created (cap and trade)?

    Best,
    Michael

  3. Where has this reader been? With record super storms and droughts in the news almost daily Global Warming is a hotter topic than ever. In California there are heated discussion about where funds from cap and trade will go. The governor wants to put it into the general fund. Others would like it to go to transportation alternatives. Cap and Trade is just getting started.

    1. Theodora — Good question. It may depend on what you mean by a “straight energy tax.” If it’s a tax on the sale of fuel or electricity in the state, there shouldn’t be any problem at least under this commerce clause doctrine. You’d also have to check that you weren’t collide with any federal statutes.
