Building Trust: Independent Emissions Verifier

Clean Shipping Index (CSI) Verification

Clean Shipping Index (CSI) Verification 

Cargo owners are increasingly seeking shipping partners that are environmentally responsible. The global shipping industry contributes significantly to greenhouse gas emissions, which has prompted calls for action. The Clean Shipping Index (CSI) is a voluntary initiative that empowers informed choices by ranking ships based on verified data on their emissions and efficiency. Normec Verifavia provides independent verification, which is crucial for ensuring accuracy and transparency in the maritime industry, fostering trust among stakeholders.

    Shipowners select a qualified verifier, which CSI then grants access to the submitted data. 

  3. Comprehensive audit

    The independent verifier conducts a three-phase audit, including contract review, head office visit with interviews and document review, and on-board inspection with crew interviews and logbook review. 

  4. Certification upon successful verification

How is the CSI Score Determined?

The CSI score is determined by evaluating the adoption of environmentally friendly technologies and practices onboard. Points are awarded not only for compliance with current International Maritime Organization (IMO) standards for sulfur oxides (SOx), particulate matter (PM), and nitrogen oxides (NOx) but also for implementing measures that surpass these standards. The score’s final weight is influenced by the detailed environmental data submitted through the CSI survey. 

What Vessel Types Qualify for CSI Verification?

CSI verification is open to a wide range of cargo-carrying vessels. Eligible types include, but are not limited to, general cargo ships, refrigerated cargo ships (reefers), bulk carriers, tankers, gas carriers, container ships, roll-on/roll-off (RoRo) vessels, roll-on/roll-off passenger ships (RoPax), and car carriers. This inclusivity ensures a broad segment of the maritime industry can participate in the CSI program. 

What Does the CSI Verification Process Involve?

For a vessel to undergo CSI verification, a comprehensive 25-question survey needs to be completed. This survey covers key areas such as emissions of carbon dioxide (CO2), nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM), alongside chemical usage, and water and waste management practices. Additionally, the vessel’s Energy Efficiency Operational Indicator (EEOI) must be calculated in accordance with the IMO’s guidelines as per MEPC.1/Circ.684. Verification assesses data from the last 12 months to ensure compliance and environmental performance. 

How are points allocated?

Scores are allocated based on the implementation of eco-friendly solutions, with additional points awarded for measures exceeding current IMO regulations on SOx, PM, and NOx. The weighting depends on the environmental data provided in the survey. 

Which types of vessels are eligible for CSI verification?

Practically all cargo-carrying vessel types, including general cargo, reefer, bulk, tanker, gas carrier, container, RoRo, RoPax, and car carrier. 

What is required for CSI verification?

Verification entails providing information from a 25-question survey regarding the vessel’s emissions (CO2, NOx, SOx, PM), chemical usage, and water and waste management. Additionally, the company must have the EEOI calculated and available for the vessels under audit, adhering to IMO requirements outlined in MEPC.1/Circ.684. Data from the preceding 12-month period is assessed.
