Maritime Compliance Dashboard

International shipping has entered a structurally different regulatory era. What was once a gradual efficiency-driven policy landscape has evolved into a multi-layered carbon compliance regime with direct financial consequences, operational constraints, and long-term asset valuation implications.

In July 2023, the International Maritime Organization adopted its revised greenhouse gas strategy, formally committing international shipping to reach net-zero emissions by or around 2050, with interim checkpoints for 2030 and 2040. While the IMO framework establishes the global decarbonization trajectory, regional regulators have moved faster and further in introducing binding market-based measures.

The inclusion of maritime transport in the EU Emissions Trading System marks the first time international shipping faces direct carbon pricing at scale. From 2024 onward, ship operators calling at EU ports must surrender emission allowances based on verified CO₂ output, with coverage expanding from 40% in 2024 to full exposure by 2026. This mechanism transforms emissions from a technical metric into a balance sheet liability, directly linking operational decisions to cash flow and risk management.

Simultaneously, the FuelEU Maritime Regulation introduces a parallel compliance obligation beginning in 2025, targeting the greenhouse gas intensity of energy used on board. Unlike EU ETS, which prices emissions, FuelEU regulates fuel quality performance on a lifecycle basis. This creates structural incentives for alternative fuels, onshore power supply, and wind-assisted propulsion, while embedding penalty mechanisms for underperformance. Operators must now manage not only how much carbon they emit, but the carbon intensity of the energy they procure.

Overlaying these EU instruments is the Carbon Intensity Indicator (CII) regime under the IMO framework, which rates vessels annually from A to E based on operational efficiency relative to reference lines. A persistent D or E rating triggers mandatory corrective action plans and may influence charter attractiveness, financing terms, and long-term asset value.

Taken together, these frameworks do not operate independently. They interact operationally, financially, and strategically. A fuel switch that improves FuelEU compliance may affect EU ETS exposure. Speed optimization decisions that improve CII ratings may alter voyage economics. Allowance procurement strategies must account for evolving fuel pathways and trading patterns. Compliance is no longer a siloed reporting task—it is an integrated optimization problem spanning operations, finance, procurement, and commercial strategy.

Against this backdrop, shipping companies require systems that move beyond static reporting tools. They need platforms capable of continuously translating operational data into regulatory outcomes, financial exposure, and forward-looking risk indicators across multiple frameworks simultaneously.

The Maritime Compliance Dashboard has been developed precisely for this new regulatory reality. It consolidates EU ETS, FuelEU Maritime, and CII obligations into a single analytical environment, enabling operators to quantify exposure, anticipate compliance gaps, and align operational decisions with regulatory and financial objectives in real time.

Maritime Compliance Dashboard
Key Features

1. Real-Time Fleet Compliance Overview

The dashboard provides a consolidated compliance view across all applicable regulatory frameworks:

EU ETS Exposure:

  • Verified CO₂ emissions

  • Coverage classification by voyage type

  • EUA (European Union Allowance) requirements

  • Phase-in application (40% in 2024, 70% in 2025, 100% from 2026)

  • Mark-to-market financial exposure based on current EUA prices

Coverage logic:

  • Intra-EU voyages → 100% of emissions covered

  • EU ↔ non-EU voyages → 50% of emissions covered

  • Non-EU ↔ non-EU voyages → 0% covered

  • At berth in EU ports → 100% covered

FuelEU Maritime Compliance:

  • Well-to-wake GHG intensity (gCO₂e/MJ)

  • Annual reduction target tracking (2% from 2025 baseline)

  • Compliance balance (banking, borrowing, pooling)

  • Penalty exposure modelling

  • Onshore Power Supply (OPS) compliance

  • Wind-assisted propulsion reward factors

CII Ratings:

  • Annual Attained CII (AER-based)

  • Reference line comparison (per MEPC.339(76))

  • Rating bands A–E (per MEPC.338(76))

  • Projected end-of-year rating

  • Corrective action planning for D/E risk

Fleet-level aggregation enables compliance officers and management teams to assess exposure, risk, and capital requirements across the entire portfolio.

2. Vessel-Level Compliance Profile

Each vessel includes a dedicated compliance workspace featuring:

  • Annual emissions history (from 2023 onward)

  • ETS-classified voyage log with automated coverage allocation

  • Fuel consumption records (BDNs, noon reports, flow meters)

  • Verified MRV data alignment

  • CII historical ratings and forward projections

  • FuelEU annual compliance balance

  • Credit tracking (OPS, wind, pooling)

All data is structured to support verifier-ready documentation and audit trails.

3. Intelligent Voyage Management

The system automatically evaluates each voyage against all applicable frameworks.

For EU ETS:

  • Dynamic classification based on port pairings

  • Automatic 100% / 50% / 0% coverage allocation

  • Berth emissions inclusion

  • Real-time EUA requirement calculation

For FuelEU:

  • Energy mix analysis

  • Lifecycle emission factor application

  • Voyage contribution to annual intensity

For CII:

  • Distance, cargo proxy, and fuel inputs

  • Continuous AER impact monitoring

Voyage completion triggers synchronized recalculation across all regulatory layers, ensuring up-to-date compliance positioning.

4. Advanced Regulatory Calculation Engine

The backend architecture exposes stateless calculation services implementing:

EU ETS:

  • CO₂ emissions using IMO emission factors

  • Phase-in schedule logic

  • EUA requirement computation

  • Exposure modelling based on EUA price scenarios

FuelEU Maritime:

  • Well-to-wake GHG intensity calculation

  • Annual limit comparison

  • Banking, borrowing, and pooling logic

  • Penalty projections as defined in regulation

CII:

  • AER computation methodology

  • Vessel-type reference line modelling

  • Rating band allocation

  • Multi-year trajectory simulation

All calculation logic aligns with applicable IMO and EU regulatory texts and is version-controlled to accommodate future amendments.

5. Proactive Compliance Alerting

An embedded alert system continuously monitors regulatory risk indicators:

Critical Alerts:

  • EUA shortfall risk

  • Projected FuelEU penalty exposure

  • CII downgrade to D/E (projected or confirmed)

Warning Alerts:

  • D-rating trajectory risk

  • FuelEU compliance deficit trending

  • Phase-in escalation impact

Advisory Alerts:

  • Regulatory amendments

  • Reporting deadlines

  • Verification milestones

All alerts are traceable, assignable, and auditable to support internal governance processes.
