Yeah, makes sense. In fact I don't care much if oil is taken out or not. I just came up with a funny scheme. Each person submits a bid saying "I'd like to receive X dollars per 1MT increase in net daily emissions, and I'm willing to pay the same sum per 1MT decrease". The tricky part is paying for second derivative: not CO2 concentration, not emissions, but change in emissions. Then as the emissions actually happen, they get tallied up by the government, an average "price per 1MT increase" gets determined, and emitters are forced to pay that price, so everyone gets paid (or pays) exactly as they asked. If carbon capture also happens, then carbon capture companies also get paid, either by emitters if there's a net increase, or from people's stated bids if there's a net decrease. This seems weird at first, what if everyone submits million-dollar bids? Well, then emitters reduce emissions for a short time and take everyone's money. On the other hand, what if everyone submits zero? Then emitters keep increasing emissions, and everyone misses out on being paid. So there's some optimal bid in between. Anyone who wants emissions to go down just submits a larger bid.
