Platts proposes to launch a European SAF Cost of Abatement Price Assessment May 11

Platts, part of S&P Global Energy, proposes to launch a daily assessment for European Sustainable Aviation Fuel (SAF) Cost of Abatement Price effective May, 11 2026.

The SAF cost of abatement assessment would reflect the implied cost per metric ton of carbon dioxide equivalent emissions (CO2e) avoided when substituting fossil-based Jet A-1 with neat SAF, based on Platts SAF FOB FARAG ( SUAFB00 ) and standardized lifecycle emissions assumptions.

The proposal follows market feedback, highlighting demand for a transparent and standardized index amid diverging methodologies used by market participants.

The assessment would be expressed in $/mtCO2e, enabling standardized comparison across fuel pathways and decarbonization options. The assessments would be published daily at the market close at 4:30 pm London time, following the London publishing calendar.

Calculation

The assessment incorporates differences in fuel energy content by applying net heat of combustion values of 42.8 MJ/kg for Jet A-1, in line with minimum ASTM D1655 specifications, and 4 4 MJ/kg for HEFA-SPK as defined under Annex III, Directive (EU) 2018/2001 (Renewable Energy Directive) , as amended (latest consolidated version 2024).

Carbon intensity assumptions are based on the EU Renewable Energy Directive fossil fuel comparator, with Jet A-1 assigned a baseline value of 94 gCO2e/MJ. HEFA-SPK is modeled using a lifecycle greenhouse gas reduction of 80%, resulting in a carbon intensity of 18.8 gCO2e/MJ.

Example Calculation:

• 94 gCO2e/MJ (CI) multiplied by 0.8 (GHG) = 75.2 gCO2e/MJ avoided

• 75.2 gCO2e/MJ multiplied by 44,000 (HEFA-SPK Energy in MJ/mt) = 3,308,800 gCO2e/mt

• 3,308,800 divided by a million = 3.30 tCO2e

• 3.30 tCO2e divided by 1.02803 = 3.21 tCO2e

• $1540/mt divided by 3.21 tCO2e = $479.75/tCO2e (SAF Cost of Abatement price)

This assessment would appear in Biofuelscan, CMD and the Platts price database.
