FuelEU Maritime Pooling, Banking & Borrowing Strategy Tool

FuelEU Compliance Portfolio Optimizer

FuelEU Maritime Pooling, Banking & Borrowing Strategy Tool

Compare fleet pooling, same-ship banking, advance borrowing and penalty exposure across the current and next reporting period. Build a ship-level compliance portfolio, test the pool validity constraints, quantify borrowing debt and identify the lowest-cost flexibility path before verifier submission.

Reporting & Strategy Assumptions

The reporting-year target is populated from the current Article 4 reduction schedule. You can override the calculated target for scenario testing.

Reporting year

GHG intensity target

gCO₂eq/MJ

Used for the borrowing-cap screen. Override if your scenario requires another verified target.

Pool surplus transfer / opportunity value

€ / t CB

Pool administration cost per participating ship

€

Borrowing administration cost per ship

€

Discount rate for next-period cost

Minimum residual pool surplus

t CB

Keeps the modeled total pool compliance balance positive instead of exactly zero.

Objective

Quick Fleet Portfolio

Use positive quantities for both surplus and deficit. The tool applies brought-forward bank to current deficit first, then evaluates pooling, borrowing and unresolved penalty exposure.

Total current compliance surplus

t CO₂eq CB

Total current compliance deficit

t CO₂eq CB

Banked surplus brought forward

t CO₂eq CB

Expected next-period fleet balance

t CO₂eq CB

Positive = expected surplus. Negative = expected deficit before any borrowing repayment.

Average actual GHG intensity of deficit ships

gCO₂eq/MJ

FuelEU energy basis for deficit ships

Surplus ships

Deficit ships

Pool-eligible deficit share

Borrow-eligible remaining deficit share

Use 0% for a portfolio where borrowing is unavailable, including ships that borrowed in the immediately preceding reporting period.

Consecutive penalty years

Borrowing cap override

t CB

Leave blank to use 2% × target GHG intensity × entered FuelEU energy basis.

Ship Compliance Ledger

Current CB is the ship's estimated or verified GHG-intensity compliance balance before current-period flexibility actions. Positive = surplus, negative = deficit. Brought-forward bank is applied to the same ship first.

Important: This is a commercial and compliance-strategy screening model, not a substitute for the verifier, FuelEU database, statutory compliance-balance calculation or legal advice. Pool composition and allocation must satisfy the regulation and be accepted through the required FuelEU workflow.

Regulatory guardrails modeled: banking applies a surplus to the same ship's following reporting period; borrowing creates a 1.1 deduction in the following reporting period, is capped and cannot be used in two consecutive reporting periods; a ship participating in a pool cannot also borrow for that reporting period; pool total compliance must remain positive, a deficit ship cannot become more negative after allocation, and a surplus ship cannot become negative. Definitive pool composition and allocation are recorded by the selected verifier by 30 April of the verification period under the current regulation.
