In the original Inflation Reduction Act, which significantly expanded the existing carbon capture tax credit, there was a price differential baked into the tax credits: Producers got more money per ton of CO2 they sequestered underground without any oil production involved, and less for CO2 used specifically to produce more oil and gas. But the One Big Beautiful Bill Act eliminated this differential, allowing producers to collect on the full credit even if they are using CO2 to produce more fossil fuels. The total expansion of tax credits for carbon capture in the One Big Beautiful Bill Act, the analysis found, could send out more than $1.4 billion of public money to oil and gas companies each year.
