It’s been known to happen that environmental regulations turn out to be ill-considered, counterproductive, entirely corrupt instances of regulatory capture by politically dominant industries, or simply poor cost-benefit tradeoffs. Gigantic pickups are a consequence of poorly considered environmental regulations in the United States, for instance.

True, at their core though, those aren't environmental at their heart but rather something else green-washed, be it corruption, subsidisation or something else.

Or sometimes the regulators make mistakes. Good intentions are no guarantee of good outcomes.

True.
