This is the fundamental problem with carbon credits. There is currently no wide scale production system for scrubbing CO2 from the atmosphere. Because of this, the price of the carbon credits is set arbitrarily by politicians. It's meaningless. A carbon market only works if there are sellers. Companies that sequester carbon for X dollars per ton so producers need to buy enough credits to cover their emissions. There could even be competition as people find more efficient ways to remove carbon from the atmosphere. Currently the whole thing is a big game that nobody takes seriously. It is a game because if we actually priced in the cost of scrubbing CO2 from the atmosphere using current technologies no fossil fuel industries would be competitive. It would threaten the gravy train for people like Rex Tillerson, so it's a nonstarter politically.
