Unpacking Eme Homer: Cost, Proportionality, And Emissions Reductions, Daniel A. Farber

Michigan Journal of Environmental & Administrative Law

Interstate air pollution can prevent even the most diligent downwind state from attaining the air quality levels required by federal law. Allocating responsibility for emissions cuts when multiple upwind states contribute to downwind air quality violations presents a particularly difficult problem. Justice Ginsburg’s opinion for the Court in EPA v. EME Homer City Generator, L.P., gives EPA broad discretion to craft regulatory solutions for this problem. Although the specific statutory provision at issue was deceptively simple, the underlying problem was especially complex because of the large number of states involved. Indeed, neither the majority opinion nor the dissent seems to …

Instrument Choice, Carbon Emissions, And Information, Michael Wara

Michigan Journal of Environmental & Administrative Law

This Article examines the consequences of a previously unrecognized difference between pollutant cap-and-trade schemes and pollution taxes. Implementation of cap-and-trade relies on a forecast of future emissions, while implementation of a pollution tax does not. Realistic policy designs using either regulatory instrument almost always involve a phase-in over time to avoid economic disruption. Cap-and-trade accomplishes this phase-in via a limit on emissions that falls gradually below the forecast of future pollutant emissions. Emissions taxation accomplishes the same via a gradually increasing levy on pollution. Because of the administrative complexity of establishing an emissions trading market, cap-and-trade programs typically require between …
