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

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

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

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

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 44 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 grams CO2e/MJ. HEFA-SPK is modeled using a lifecycle greenhouse gas reduction of 80%, resulting in a carbon intensity of 18.8 g CO2e/MJ.

Example calculation (based on Platts SAF FOB FARAG barge assessment published Jan. 21, 2026):

• 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 g CO2e/mt
• 3,308,800 divided by a million = 3.30 tCO2e
• 3.30 tCO2e divided by 1.02803 (accounting for difference in calorific value) = 3.21 tCO2e
• $1,540/mt divided by 3.21 tCO2e = $479.75/tCO2e (S<AF Cost of Abatement price)

This assessment will appear in Biofuelscan, Carbon Market Daily and the Platts price database.
