Platts updates 2026 RVO assessment, 2025 cellulosic biofuel RVO percentage, effective March 30

Platts, part of S&P Global Energy, has updated its 2026 Renewable Volume Obligation weightings (RVOY026 and RVOR002) and the 2025 cellulosic weight (RVCY025) using the Environmental Protection Agency's finalized Renewable Fuel Standards for 2026, effective March 30, 2026.

The EPA released its finalized rule on March 27, 2026, and as per Platts methodology, RVO formulas may be updated when the EPA makes such changes.

As per Platts methodology, the renewable fuels are mandated by the EPA; they are subject to change without prior notice. When the EPA sets forth such changes, Platts will inform the market of any resulting changes to the assessment formulas through subscriber notes.

Prior to the final rule, Platts calculated the 2026 RVO using the 2025 Annual Energy Outlook and the proposed standards for 2026, assuming a 50% reallocation for small refinery exceptions, November Small Refinery Exemption and the updated adjustment factors. Platts launch note can be found here.

The EPA's latest RFS 2026 weightings are as follows:

Therefore, Platts calculates the 2026 RVO in cents/gal using the following formula, considering new percentages:

RVO = 9.08 % (D6) + 0.39 % (D5) + 5.24% (D4) + 0.79 % (D3)

Platts has also updated the cellulosic biofuel percentage (D3) mandate for its calculated values of the US RVO for compliance year 2025 (RVOY025).

The update follows the EPA's partial waiver of the 2025 cellulosic biofuel volume requirement, published March 27, 2026.

The updated 2025 D3 percentage is 0.71%, down from the EPA's initially stated 0.81%.

Platts publishes current-year RVO (RVOR002) and 2025 RVO ( RVOY025 ) in the Platts Biofuelscan, LatinWire, USMarketWire, Fuel Ethanol Report and Biomass-Based Diesel Report.

Symbols also appear on Platts Alert pages PBF10, 201, 210, 301, and 310, and PGA, PFR 28, 164,165, 310, 330, 331, 350, 351, 410, 411, 430, 431, 450, 451, 481.
