Clean Shipping Index (CSI) Verification

Verifavia is the first Independent Verifier to Provide Clean Shipping Index (CSI) Verification.

If your ships report to the Clean Shipping Index (CSI), we can independently verify your submission to the CSI against the requirements of the CSI requirements (Methodology and Reporting Guidelines and Verification Guidelines) and the ISO 14065 standard.

The verification of CSI data and information by an independent third-party is a mandatory requirement of the CSI to guarantee the quality of the  data reported.

We can perform:
> initial CSI verification of your ships
> CSI re-verification
> annual verification of SOX/PM and CO2 performance data

CSI Verification - 6 steps to report verified data to the CSI

In practice, we conduct the CSI verification audit in three main phases. Audit conducted with a head office visit at company’s head office and on-board audit as per CSI requirements.

Data to be verified


Extended Verification deadline of CSI scores

Due to the short timespan between the approval of the Swedish Maritime Administration (SMA) regulations on fairway dues and when they enter into force, the SMA has decided to give a grace period for the verifying of CSI scores. For more details please click here.
