We've got enough problems without shooting ourselves in the foot
A somewhat depressing article in the NY Times about wasted money being spent on the waste gas HFC-23, so much so that it's been produced in order to be destroyed. It looks like the problem is finally being brought under control, with the UN tightening down what qualifies and the Europeans finally rejecting outright doing any more future payments for this. Still, the problem has been obvious for years. Offsets can work, but only if they're done right.
