(NAFB.com) – The government released short-term guidance on accessing clean fuel tax credits under the Inflation Reduction Act. However, the announcement fell short of finalizing the program’s details. Farm Policy News says biofuel groups were hoping for more clarity on the tax credits for fuels that help combat climate change. The groups are hopeful that more complete guidance will provide a pathway for corn-based ethanol to expand its market as a sustainable aviation fuel feedstock. The Treasury Department says it provides further details on how to ensure fuels meet certain emissions-reductions criteria to access the subsidy and adds that a crucial climate model upon which the program relies will be available in the future. Reuters says the administration intends to release the program’s climate model this week, but it will not include adjustments for so-called climate-smart agricultural practices like no-till farming, which ethanol hoped it could use to meet the lifecycle emissions requirements.
