Clean Shipping Index

For clean air and healthy oceans.

Clean Shipping Index is an independent and holistic labelling system for assessing vessels' environmental performance. It serves as a practical tool for differentiating port and fairway fees or selecting more sustainable shipping alternatives.

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.

  • Science at the core

    The Clean Shipping Index is an independent labelling system for the environmental performance of vessels, which rewards beyond legal compliance. The Clean Shipping Index Methodology and Reporting Guidelines are developed by a technical committee with scientists and industry representatives.

    Read more about Methodology and Verification

Methology

  • Vessels are scored beyond legal compliance. As legal compliance sets a baseline, every point scored is a better performance than legal compliance demands.
  • 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.
  • The methodology is applicable on all types of vessels (tanker, container, cruise, etc.)
  • 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.
  • 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.

Why did Preem become a Clean Shipping Index user?

Preem has been working with safety focus in procurement for many years. It is important to make sure that the risks are kept to a minimum when transporting petroleum products on tankers – this is of course important to everyone in the business. We have been working with vetting (a type of procurement with specific demands and requirements on safety issues and risk assessment for vessels) for a long time. The questionnaires consist of many questions which gives us detailed information on the routines, certificates, equipment etc. that needs to be implemented and validated onboard the vessel to make sure it is handled in the best and safest way possible. In order to take this procurement assessment one step further we use the Clean Shipping Index database to get information about the environmental performance of the tankers. The Clean Shipping Index, gives Preem the opportunity to look ahead and beyond current emission regulations. It corresponds well with our Company’s vision “Preem leads the transition towards a sustainable society”. By being a part of developing the index, and subsequently requiring that tankers managed by us rate well in all categories, we aim to reduce the environmental impact from our transports.

Can you describe your environmental ambitions with regard to transport?

At Preem we have a double responsibility when it comes to environment – we need to make sure that products can be developed to satisfy the needs of the society, and at the same time make sure we do it in an environmentally and ethically sustainable way. At Preem we focus on partnerships to move towards a sustainable development. It can for instance be partnerships between companies, researchers, authorities and/or organizations as this will give us more expertise to reach our overall sustainability goals. A part of this strategy is to network with other Clean Shipping Index users – to work together with other ambitious companies which also push for a cleaner, healthier environment.

How would you describe the Clean Shipping Index?

The CSI is a tool which helps us, as transport purchaser, to select high-performing shipping companies when it comes to environmental criteria. The CSI also assists when it comes to giving us input on measuring emissions. We can either look at the over-all environmental performance of a shipping line or the details of a specific vessel or benefit from the CSI’s ranking system entailing a holistic perspective where categories such as CO2, SOx and PM, NOx, chemicals and water and waste are included.
