text: Thats where we are now with GHGs. We are going to get more or less GHG regulation over time depending on who is in the White House and whether the particular GHG regulations that EPA issues are legally defensible. Thus, each regulation is going to have to be attacked (or defended) on the merits. My own view is that EPAs latest GHG proposal, for new source performance standards for coal-based electric generation, is not legally defensible and will be overturned in Court. But there will be many more GHG regulations to come, and we are in for another long, hard rule-by-rule slog under the CAA, in this case to shape the timing and stringency of GHG regulation in this country.
