Rewriting the RFS Playbook: The Impact of No Half-RIN and Higher RVOs on Projected Biomass-Based Diesel Production and Feedstock Use for 2026-2027

Why It Matters

Higher RVOs boost domestic biofuel output but reallocate feedstock demand toward imports, reshaping the U.S. biomass‑based diesel supply chain and pressuring feedstock markets.

Key Takeaways

• Updated RVOs raise biomass diesel targets ~20%
• Domestic feedstock demand drops 20% with half‑RIN removal
• Capacity utilization reaches near‑100% by 2027
• Total feedstock demand climbs 58% versus 2023‑25 average
• Imports fill gap as domestic feedstock shrinks

Pulse Analysis

The EPA’s pending rulemaking removes the half‑RIN penalty that previously discouraged imported biofuels, replacing it with higher renewable volume obligations for biomass‑based diesel. By setting RVOs at 5.25 billion gallons for 2026 and 5.61 billion gallons for 2027, and applying a 1.6‑to‑1 RIN equivalence, the agency creates obligations roughly 20% larger than earlier proposals. This shift not only simplifies compliance for importers but also raises the projected D4 RIN generation to over 12 billion gallons by 2027, establishing a robust compliance buffer.

Higher obligations translate into markedly increased production and capacity use. Renewable diesel capacity, already at 5.0 billion gallons, is projected to operate at 78% in 2026 and nearly 100% in 2027, while FAME biodiesel remains flat before expanding to 2.3 billion gallons. Feedstock composition adjusts as domestic sources lose about 8 billion pounds annually—roughly a 20% cut—while imported feedstock rises to offset the shortfall. Overall feedstock consumption climbs from 40 billion pounds in the 2023‑25 average to 63 billion pounds by 2027, a 58% surge that intensifies demand for animal fats, used cooking oil, and soybean oil.

The policy trade‑off reshapes market dynamics. Biofuel producers benefit from higher guaranteed volumes and a streamlined import regime, but domestic feedstock suppliers face reduced demand, potentially compressing margins. Importers, conversely, stand to capture the displaced feedstock, altering trade flows and pricing. With total U.S. demand approaching half of global biomass‑based diesel feedstock supply, stakeholders must navigate tighter supply constraints, invest in feedstock diversification, and monitor regulatory developments that could further influence RVO levels or RIN equivalence values.
