Clean Fuels Alliance America has submitted formal comments to the U.S. Treasury Department regarding proposed rules for the 45Z Clean Fuel Production Credit, calling for additional clarity as the agency works to finalize the policy. The organization praised Treasury for incorporating earlier industry feedback into the updated proposal. However, it emphasized the need for timely and definitive guidance to support producers navigating the new credit. “The proposed regulations accurately respond to taxpayer comments on prior guidance and provide additional certainty for the industry,” the group stated, while noting that further clarification is still needed. Kurt Kovarik, vice president of federal affairs, said producers are particularly seeking confirmation that the updated rules will apply to fuel sales made in 2025, when the credit took effect. Officials say clearer rules could boost domestic energy production and expand market opportunities for U.S. farmers.
