Clean Shipping Index
For clean air and healthy oceans
Independent and holistic labelling system
Clean Shipping Index is an independent and holistic labelling system of vessels' environmental performance; a practical tool for differentiating port- and fairway fees or choosing more sustainable shipping alternatives.
Our vision
Clean ships sailing in healthy seas.
How will we accomplish this?
By providing key players in the maritime supply chain with the information they need to make environmentally responsible decisions. This results in competitive economic advantages for environmental leaders in the shipping industry. It’s a win-win situation for both environment and business.
Clean Shipping Index offers shipping companies:
Reduced fairway dues by the Swedish Maritime Administration (SMA)
Reduced port fees by: Ports of Stockholm, Port of Gothenburg, Port of Vancouver, Port of Prince Rupert, Port of Gävle, Brofjorden, PetroPort, Port of Turku
Information about discounts and how to apply for them can be found in the FAQ.
Benefits with Clean Shipping Index
Joining Clean Shipping Index offers numerous advantages. No matter your role in the shipping industry.
The Swedish Maritime Administration has chosen Clean Shipping Index as a practical tool for differentiating fairway dues
- Clean Shipping Index is a practical tool that can directly be used by any key player in the maritime supply chain.
- The holistic approach to emissions, including more categories than only air emissions, ensures a high score can only be obtained when a vessel scores points in all possible emission categories.
- Third-party verification is an important part of the methodology. A vessel certificate can only be obtained after a verification process of the self-assessed data, ensuring the credibility of scored points. Port- & fairway due rebates are only given when the data are verified. Shipowners can use the certificate to receive these rebates and to market their verified environmental performance.
- Vessels are scored beyond legal compliance. As legal compliance sets a baseline, every point scored is a better performance than legal compliance demands.
- Costs for verification of self-assessed data are low compared to the possible discounts on port- & fairway dues. Therefore obtaining a CSI certificate often directly pays off after the date of issue.

Database access
- As a database user you’ll access detailed information on the environmental performance of all registered vessels. A broad range of maritime stakeholders currently have access to the database with information on environmental performance of ships. Any company or organisation sharing our vision of "Clean ships sailing in healthy seas" can become user with full database access.
- The user fee for Clean Shipping Index is €2,800 per year. In order to register as a user, please contact us.
- Shipowners becoming users have the possibility to issue 10 CSI vessel certificates per year without the €500 admin fee. The CSI logo can be used as a performance label in marketing.
- Please contact us if you have any other questions regarding the use access of Clean Shipping Index or read more in the "benefits" presentation under ¨download¨.
