The OPX is a benchmark index that tracks real FuelEU pooling transaction prices. Unlike simple averages, it uses a basket-weighted methodology to reflect what buyers actually pay across small, medium, and large deal sizes. This makes OPX a reliable reference point for shipping companies when planning EU ETS and FuelEU compliance.

OPX is calculated from available FuelEU pooling offers across three representative volume groups: 500–1,499, 1,500–2,999 and 3,000–10,000 MTCO₂eq. Each eligible offer is assigned to the groups covered by its quoted volume range. Fixed prices are used directly, while flexible prices are calculated using linear interpolation. The resulting average price for each group is then combined into the OPX.

No. OPX reflects listed offer prices only. It does not reflect executed transactions, penalty levels, or forward projections.

Surplus balances are year-specific and not interchangeable.
OPX 2026 and OPX 2027 are calculated separately to reflect distinct compliance years.

OPX provides transparent pricing for FuelEU pooling, allowing companies to compare pooling costs with penalties or biofuels. It gives owners and managers a neutral settlement basis for charter-party and SHIPMAN agreements, reducing disputes and supporting fair cost-sharing.

Unlike other pooling indexes, OPX is:
Volume-adjusted – reflects actual transaction sizes.
Transparent – methodology is published and easy to understand.
Independent – no fees or margins are taken from transactions, keeping the index unbiased.
This makes OPX more accurate and trusted for negotiations and compliance planning.

OPX is published monthly and reflects observable listed market conditions during the reference month.

OPX is updated regularly with new market transactions, ensuring that shipping companies, owners, and managers have up-to-date insight into FuelEU pooling prices. This helps with timing compliance decisions, comparing options, and preparing for upcoming pooling windows.
