(NAFB.com) – USDA has issued guidance regarding climate-smart crops used in the manufacture of biofuels. The interim rule gives insight into how farmers can access renewable fuel tax credits, though a Trump administration freeze on recent federal regulations is creating more uncertainty. The U.S. Department of Agriculture introduced guidance to help farms measure the emissions saved from climate-smart crops grown for biofuels, a step toward helping producers access renewable fuel tax credits. The interim rule, released roughly a week before the end of Former President Joe Biden’s term, establishes standards to track and report the impacts of sustainable farming practices in corn, soy and sorghum — three major feedstocks used in alternative fuels. The guidance had been expected to increase farm participation in biofuel tax credit programs. However, a Trump administration freeze on recent federal regulation injects uncertainty into the future of these new opportunities.
