J.S. at Environmental Economics sighs:

The modern Republican Party has absolutely no affirmative environmental agenda whatsoever, and goes so far as to contest the entire rationale for continued environmental progress. Ironically, this extremely reactionary environmental agenda is coming at a time when the ideas that Republicans once championed are now widely accepted as the best ways to structure environmental policy.

Yes, I'm old enough to remember when cap and trade was the right-wing, pro-market view. And the conflict between conservatism and conservation is a perverse one. In so many ways, conservatism should be the greener option, as it has become in Britain.
