Carbon credits are nonsense because there is no large scale atmospheric carbon removal industry, so you are trying to run a market using only a supply curve with no demand curve. There is no way to set the price so the market doesn't work, it ends up being a tax that doesn't even directly contribute to the goal of removing the carbon emitted by industry. For carbon markets to work properly there would need to be industrial processes that pull CO2 out of the atmosphere at a price per ton. Companies would then pay those companies to remove the CO2 they release at that price point. Multiple companies could compete to be the most efficient at removing CO2 and taking the largest share of the market. But it has been 30 years now and we still don't have a supply side to the market beyond some penny ante tree planting and research projects.
