CII Calculator – Carbon Intensity Indicator (CII)

MariApps designed the smartOps Basic module to efficiently capture and seamlessly integrate comprehensive vessel operations data. This module helps meet EU MRV and IMO DCS reporting requirements for compliance.

smartOps Basic helps maritime stakeholders manage and report operational data in a compliant and efficient manner.

Get a complete understanding of the commercial impact of the Carbon Intensity Indicator (CII) with smartOps’s CII calculator. As an integral feature of the CII Dashboard, the calculator enables users to compute and project the impact of CII ratings based on modifications to key parameters.

Explore a user-friendly tool equipped with dynamic forms that generate depending on engine types and vessel layout. Utilize our CII calculator to obtain an accurate estimation based on the primary determinant in this formula.

What is Carbon Intensity Index?

The Carbon Intensity Indicator (CII) assesses a ship’s carbon emissions over time, taking into account factors such as annual fuel consumption, distance sailed, deadweight, and gross tonnage. Vessels are rated on a scale from A to E based on their emission levels.

CII requirements come into effect in January 2023

From January 1, 2023, all ships with a gross tonnage (GT) of 400 and above are required to calculate their Energy Efficiency Existing Ship Index (EEXI) to assess their energy efficiency. They must also report the annual operational carbon intensity indicator (CII) and CII rating for vessels exceeding 5,000 GT. The inaugural annual reporting is scheduled for 2023, with initial ratings issued in 2024.

When will CII rating enter in force ?

Starting from January 1, 2023, both CII and EEXI will be implemented as the new IMO regulations for monitoring Green House Gas (GHG) emissions and advancing the decarbonization of the shipping industry.

What is the diffrence between CII and EEXI ?

The EEXI is a guideline used to assess the energy efficiency of vessels with a gross tonnage (GT) exceeding 400, falling within the scope of MARPOL Annex VI. Calculated with reference to the Energy Efficiency Design Index (EEDI), the ship’s EEXI is verified during its initial annual, intermediate, or renewal survey for the International Energy Efficiency Certificate (IEEC).

Do I need approved calculators ?

While approved calculators are not obligatory, the attained annual CII must undergo verification. The operational carbon intensity rating will be documented in a “Statement of Compliance,” providing additional details in the ship’s Ship Energy Efficiency Management Plan (SEEMP).

How does CII impact ship owners?

CII ratings will greatly influence how appealing ships are for business. Charterers will steer clear of poorly rated assets, leading to higher insurance costs and difficulties securing preferred slots in global ports and terminals. These vessels may also face increased port fees. Ship owners can prioritize investments in fuel-efficient technologies and sustainable practices to enhance their CII rating and maintain competitiveness.

How can you reduce your Carbon Intensity Index?

MariApps can assist you in meeting CII requirements and making informed decisions to enhance ratings and improve technical and operational aspects. Our data-driven approach is customized to suit your specific needs.
