Platts updates 2026 RVO assessment, effective Sept. 18

Platts, part of S&P Global Commodity Insights, has updated the 2026 Renewable Volume Obligation calculated values using the revised proposed percentage standards for 2026, mandated by the US Environmental Protection Agency effective Sept. 18, 2025.

Platts has updated the RVO, based on the 2026 50% reallocation percentages as proposed by the EPA.

The RVO is the aggregated cost of the RIN percentages per gallon of transportation fuel as the US EPA mandated in the Renewable Fuel Standard Program.

The US EPA mandates the use of biofuels, and hence the RVO calculation is subject to change. On Sept. 16, the EPA submitted a proposal for 2026 and 2027 RVO addressing the reallocation of Small Refinery Exemption granted on Aug. 22.

As per Platts' methodology, RVO formulas may be updated at any time when the EPA makes such changes.

The RVO is a calculation that combines Renewable Identification Number prices and weights them based on federal biofuel blending mandates. The current and previous percentages considering 50% reallocation used for the 2026 RVO (RVOY026) calculated values are as follows:

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

2026 RVO formula:

RVO = 9.48 % (D6) + 0.3 9 % (D5) + 4. 46 % (D4) + 0. 81 % (D3)

These assessments are published in the daily Platts Biofuelscan, Weekly Fuel Ethanol Report, and the Weekly Biomass-Based Diesel Report.

They also appear on Platts Biofuels Alert pages PBF10, 201, 210, 301, and 310.
