Platts proposes to launch FuelEU CO2 Abatement 50% EU ETS assessments, amend B24 Singapore abatement assessment, adjust EU ETS Tank-to-Wake factors Aug 3

Platts, part of S&P Global Energy, proposes to launch a series of F uelE U abatement assessments reflecting 50% of EU ETS costs, and change its existing methodologies for several F uelEU abatement assessments, effective Aug. 3, 2026.

Platts proposes the following:

1. To launch two new FuelEU CO2 Abatement assessments that reflect 50% EU ETS costs
2. To amend the methodology of the B24 Singapore (VLSFO) (MGVLF00) assessment, and launch a new B24 Singapore (VLSFO) EU ETS exclusive assessment
3. To amend Tank-to-Wake emission factors in existing abatement calculations, in line with EU ETS regulation

1. Proposed new 50% EU ETS assessments

The EU ETS covers 50% of emissions for voyages between EU and non-EU member states and 100% of emissions for voyages occurring between two EU ports. Market feedback has indicated a need for abatement assessments that capture voyages between EU and non-EU ports. In response, Platts proposes to launch the following assessments:

• FuelEU CO2 Abatement B30 Rotterdam (VLSFO) 50% EU ETS
• FuelEU CO2 Abatement UCOME Rotterdam (VLSFO) 50% EU ETS

The new assessments would supplement the existing FuelEU CO2 Abatement assessments launched September 1, 2025 , which reflect 100% of emissions under the EU ETS , and the EU ETS exclusive assessments, launched Nov. 17, 2025.

2. B24 Singapore proposed changes & new EU ETS exclusive assessment

Platts proposes to change the methodology for the calculation of EU ETS costs for the existing FuelEU CO2 Abatement B24 Singapore (VLSFO) assessment (MGVLF00), which includes EU ETS costs. As per the EU ETS directive, voyages with one port outside the EU and one port inside the EU must account for 50% of emissions.

The current methodology calculates the EU ETS cost by multiplying the Tank-to-Wake emissions factor by Platts daily EUA value, divided by two, and also halves the final abatement cost for B24 versus VLSFO. Based on market feedback, Platts proposes to calculate the EU ETS cost by multiplying the Tank-to-Wake emissions factor by Platts daily EUA value, divided by two, without halving the abatement cost.

In line with this, Platts proposes to rename the assessment from "FuelEU CO2 abatement B24 Singapore (VLSFO)" to "FuelEU CO2 Abatement B24 Singapore (VLSFO) 50% EU ETS ," and would continue to publish it under the same symbol (additionMGVLF00).

In addition, Platts proposes to launch a FuelEU CO2 abatement B24 Singapore (VLSFO) EU ETS exclusive assessment, complementing the existing EU ETS exclusive assessments. Under the proposal, Platts would publish the following abatement assessments for Singapore:

• FuelEU CO2 Abatement B24 Singapore (VLSFO) 50% EU ETS ( MGVLF00)
• FuelEU CO2 Abatement B24 Singapore (VLSFO) EU ETS e xclusive (new)

3. Proposed amendments to Tank-to-Wake emission factors

Platts also proposes to update the Tank-to-Wake emission factors for biofuels in its FuelEU CO2 Abatement EU ETS inclusive assessments, to reflect the inclusion of methane and nitrous oxide emissions under the EU ETS from 2026.

Since Jan. 2, 2026, Platts has reflected methane and nitrous oxide emissions only for the fossil fuel volumes within its abatement assessments, and has retained Tank-to-Wake emission factors of zero for UCOME components. Platts proposes to amend the Tank-to-Wake emissions factors for UCOME components to 0.05489tCO2eq/mtfuel from Aug. 3, to include methane and nitrous oxide as per the EU ETS regulation.

For UCOME, the default emissions value is 14.9 gCO2eq/MJ under the EU Renewable Energy Directive (RED). The emissions factors for Well-to-Wake emissions are calculated in accordance with regulation (EU) 2023/1805 of the European Parliament.

This change would impact the following existing assessments, whilst the new 50% EU ETS abatement assessments proposed above would also use the updated Tank-to-Wake emission factors:

* proposed name change

Platts proposes to reflect all the above changes from Aug. 3, 2026.

The FuelEU maritime CO2 abatement assessments are expressed in $/mtCO2e, allowing for standardized comparisons across different fuel types.

The new assessments would be published on the following fixed pages for daily assessments: PGB2050, PGA2051, PRF2050; and the following for monthly averages: PGB2052, PGA2053, PRF2052.

All FuelEU CO2 abatement assessments reflect a 16:30 London time market close and follow the Platts UK publishing schedule, apart from FuelEU CO2 Abatement B24 Singapore assessments, which follow the Singapore publishing schedule reflecting a 17:30 Singapore time market close and Platts Singapore publishing schedule.

They would also be published in Platts Bunkerwire, Bunkerwire Monthly and Biofuelscan.

All FuelEU CO2 abatement assessments are published as mirror symbols in the following fixed pages for daily assessments: CMA2500, ETA2500, and the following for monthly averages: CMA2501, ETA2501. The mirror symbols will also appear in the Carbon Markets Daily report.
