S&P Global updates biofuels specifications guide for key fuels markets

Almost 2,000 biofuel price assessments now sit under one S&P Global Commodity Insights framework after the company updated its Global Biofuels specifications guide in April 2026, tying ethanol, biodiesel, renewable diesel, sustainable aviation fuel and credits to one pricing framework. The guide sits inside S&P Global’s methodology library for commodity assessments, setting the trading language behind the numbers.

Trading locations define the benchmark

The guide starts with definitions of trading locations, then moves through ethanol, biodiesel, renewable diesel, also called hydrotreated vegetable oil, sustainable aviation fuel, biobunkers, and tickets and credits. A benchmark only works when the location, product and contract convention match the cargo or certificate being traded. S&P Global’s biofuels market data platform covers ethanol, biodiesel, SAF and advanced fuels, and the specifications guide is the rulebook behind that pricing grid.

Why one fuel rarely trades like another

Biofuels move across jurisdictions with different tax treatments, blend requirements and carbon-accounting systems, which means the same molecule can face very different economics depending on where it lands. The guide gives producers, traders, airlines and refiners a common language for price discovery, but it also shows where comparability ends, especially when a physical fuel, a compliance ticket and a credit no longer clear against the same rules.

Renewable diesel and SAF often draw on similar lipid feedstocks, while ethanol markets can influence alcohol-to-jet pathways. A buyer looking at one product family therefore has to watch the others, because feedstock competition and refinery behavior can push prices, availability and margins in different directions even when the end use looks adjacent.

Physical fuel, drop-in fuel and paper value

S&P Global’s structure also separates the physical markets from the paper markets that sit around them. Biobunkers belong in the same guide because maritime demand is now part of the clean-fuels pricing map, while tickets and credits sit beside the molecule assessments because compliance value can move separately from the underlying barrel. That split matters when a contract depends on whether a shipment is deliverable, whether a credit is bankable, or whether a benchmark reflects a physical differential rather than a policy premium.

The same logic applies to regional comparisons. A cargo priced in one hub may not be directly comparable with a cargo in another unless the spec, timing and location definitions line up. Those differences are visible up front because trading location definitions sit at the top of the guide rather than at the end.

The wider S&P biofuels stack

The April 2026 specifications update sits beside a Global Biofuels Forward Curves methodology guide updated in May 2026. That forward-curves guide includes T2 Rotterdam ethanol forward curves, used cooking oil forward curves and sustainable aviation fuel forward curves, showing how S&P extends the same benchmark logic from spot-style specifications into the curve structure that desks use for hedging and procurement.

S&P Global Energy’s biofuels and bioenergy business maintains a frequently updated plant capacities database covering conventional fuels, ethanol and biodiesel, and drop-in fuels, renewable diesel and SAF. Put together, the specifications guide, forward curves and plant-capacity data form one market infrastructure layer, covering pricing, supply and timing rather than treating each fuel as an isolated niche.

Policy keeps resetting the price signals

In April 2026, S&P Global tied the U.S. Environmental Protection Agency’s new biofuel mandate to a three-year high in RIN credit prices. That kind of move feeds straight back into how market participants read physical and paper biofuels prices, since credit values can reshape margins even when gallons are unchanged.

S&P Global’s January 15, 2025 Global Biofuels Special Report placed the start of EU ReFuelEU Aviation SAF mandates in January 2025 and the deadline for EU member states to transpose RED III into national law at the end of May 2025. Those deadlines keep SAF, related credits and regional pricing structures in motion.

On June 17, 2026, S&P Global called biofuels a critical demand catalyst for agriculture amid structural surplus risk, linking feedstock markets and finished-fuel markets through the same demand pull.

Its World Biofuels, Ethanol & Feedstocks Conference 2026 is scheduled for Nov. 3-5, 2026 in Barcelona, where S&P expects to bring together more than 400 biofuels leaders for conference sessions, training and SAF Horizons discussions.
