US Senate bill would shrink tax credit for biofuels made from foreign feedstocks

Senate Republicans have proposed a tax bill extending the 45z clean fuel tax credit through 2031, mirroring the House bill's extension but differing on feedstock eligibility. The Senate version would trim the credit value by 20% for biofuels using foreign-produced feedstocks, while both bills would exclude emissions from tilling land, potentially benefiting corn-based ethanol producers. The 45z tax credit, established under the Inflation Reduction Act, aims to incentivize lower carbon intensity fuels.

Analysis

Senate Republicans have introduced a tax bill proposing an extension of the 45z clean fuel tax credit through 2031, a move that aligns with a similar House bill passed in May. A key divergence is the treatment of foreign feedstocks: the Senate proposal would reduce the credit value by 20% for biofuels derived from non-U.S. feedstocks, whereas the House bill imposes a more stringent ban on most foreign feedstocks. Both legislative proposals, however, share a provision to exclude emissions from land tilling for feedstocks like corn and soy from the biofuel's credit value calculation. This specific exclusion is anticipated to make it easier for corn-based ethanol to qualify for the lucrative tax credits, which were initially established under the Inflation Reduction Act to incentivize fuels with lower carbon intensity. The overall sentiment surrounding this legislative development is moderately positive, indicating potential benefits for domestic oil and biofuel producers who can demonstrate reduced carbon intensity, particularly those utilizing corn as a primary feedstock.

Key Decisions for Investors

• Investors should monitor companies in the U.S. biofuel sector, particularly those focused on corn-based ethanol production, as they stand to benefit from the proposed exclusion of land tilling emissions in credit calculations and the extension of the 45z tax credit.
• Consider the potential divergence between House and Senate versions regarding foreign feedstock eligibility, as this could impact companies reliant on imported feedstocks; clarity on the final bill will be crucial for assessing specific company risks and opportunities.
• Evaluate investments in the broader renewable energy and clean fuel space, recognizing the continued legislative support aimed at incentivizing lower carbon intensity fuels through 2031.
