Third party verification is needed for accessing e.g. rebates on Swedish fairway dues and certain port fees, but also for obtaining the CSI performance label for marketing purposes.

The costs for the verification are a matter between the shipping company and the verifier. We recommend to ask different verifiers for quotes. Accredited verification companies are mentioned here. CSI charges a €500 admin fee per certificate, which is invoiced via the verification company.

The Clean Shipping Index methodology is based on the 'beyond legal compliance' principle, meaning that the methodology should be updated from time to time, leading to various versions. When a vessel obtains a certificate, it is verified against that version of the methodology during the 3-year validity of the certificate. After it expires, a new certificate can be obtained, verified against the version of the methodology at that moment. When obtaining a new certificate, the easiest way is to wait until the current certificate expires and to issue a new certificate afterwards. Then the vessel is automatically verified against the new version of the methodology.

However, some shipowners would like to obtain a new certificate already while the old certificate is still active, in order to ensure avoiding a period of non-certification. But because there are different versions of the methodology, it is not possible to just issue a new certificate right away. Instead, the current certificate should be removed in that case, after which the new version of the methodology becomes available for assessment.

For these situations CSI recommends the following steps:

1. The shipowner prepares the answers to the questionnaire of the current (new) methodology in a separate file.
2. The verifier performs the entire verification procedure.
3. The verifier prepares the assessment (including the scores that will be given + an explanation) in a separate file.
4. The verifier removes the current certificate.
5. ASAP after this: The shipowner closes and re-opens the vessel information and fulfills their self-assessment, which is based on the newest version of the methodology.
6. ASAP after this: The verifier does the assessment and issues the new certificate, with a new 3-year validity.
