The Legal and Administrative Risks of Climate Regulation

Dramatic and rapid reductions in greenhouse gas emissions are necessary to stabilize atmospheric concentrations of greenhouse gases (GHGs) at acceptable levels. Prioritizing federal environmental regulation as the primary means of achieving these goals may be a strategic mistake. Regulatory mandates, particularly if based upon existing statutory authority, will be vulnerable to legal attack, obstruction, and delay. Climate legislation can reduce the legal risks and accelerate the rate of policy implementation, but only on the margin. Adopting regulatory controls, sector-by-sector, technology-by-technology will be immensely resource intensive for the EPA and other federal agencies. Even with authorizing legislation, federal regulatory strategies may remain more time-consuming, conflict-ridden, and legally vulnerable than fiscal measures. A carbon tax, in particular, would be more legally secure and administratively easier to implement than regulatory controls on energy use and GHG emissions.
