Platts proposes to modify CI for renewable diesel margin indicators, effective Jan. 5, 2026

Platts, part of S&P Global Commodity Insights, proposes to modify the carbon intensity (CI) for the Renewable Diesel (RD) Soybean Margin Indicator (RRDFJ00) and RD Tallow Margin Indicator (RRDFK00), considering the latest guidance stated in the Big Beautiful Bill Act, effective Jan. 5, 2026.

According to the Big Beautiful Bill Act, the emissions rate shall be adjusted to exclude any emissions attributed to Indirect L and U se Change (ILUC) from the calculation of the Clean Fuel Production Credit (CFPC). These amendments apply to transportation fuels produced in 2026.

In line with the Big Beautiful Bill Act, Platts proposes to modify the reference carbon intensity for the margin indicators to reflect the change for the calculation of the CFPC while maintaining the ILUC for the Low Carbon Fuel Standard credit calculation.

The proposed CI values are derived from S&P Global Commodity Insights research and analytics data, based on the 45ZCF-GREET model excluding ILUC and rounded to the nearest multiple of 5 kgCO2/MMBtu.

The reference CI scores for the tallow and soybean oil margin indicators would be the following:

Platts publishes the RD margin indicators in Platts Connect, Biofuelscan, Biomass-Based Diesel Report and fixed pages PBF0010, PBF0011 and PBF0012.
