Environment

With all federal and state policies on the books as of June 2024, we estimate the US is on track to reduce its GHG emissions by 38-56% below 2005 levels in 2035, representing at least a doubling—and potentially as much as a four-times increase—from the pace of annual emissions abatement from 2005 to 2023. On the way to 2035, we find the US could reduce its emissions by 32-43% below 2005 levels in 2030. These emissions reductions under current policy are a measurable acceleration in mitigation even compared to our Taking Stock 2022 edition from just before the passage of the IRA, in which we found the US on track for a 24-35% reduction below 2005 levels in 2030. But they are not enough for the US to achieve its 2030 climate commitment under the Paris Agreement of a 50-52% reduction by 2030, or deep decarbonization by mid-century.
