We understand that shipping is a highly efficient form of transport, but it is also, according to independent analysis from management consultants Booz & Co., “the largest potential energy efficiency opportunity in the transportation sector where new financing models will make a difference.”

ShippingEfficiency.org enables anyone with access to the internet to tell an efficient, low-emission ship from an less efficient one, for the first time. Using a simple search function, users can pull up an A to G rating for around 60,000 existing ships, including the majority of the world's container ships, tankers, bulk carriers, cargo ships, cruise ships and ferries.

The database is fuelled by the United Nations' International Maritime Organization's (IMO) for the Energy Efficiency Design Index (EEDI) and data from the world's largest ship registry, IHS Fairplay.

Ship-owners and operators are encouraged to update records at ShippingEfficiency.org when efficiency improvements to vessels have been implemented (see bottom of vessel search pages).

ShippingEfficiency.org has applied this data into its own A to G labeling system. This system is not affiliated with CCWG methodology.

In addition, the website hosts a searchable tool based on leading carbon calculation methodologies. We currently use the Clean Cargo Working Group's methodology for benchmarking ocean container vessels CO2 efficiency against other vessels plying the same major container routes (eg: Asia to Europe). The CCWG index rating only applies to container vessels, and is calculated in grams of CO2 per twenty-foot equivalent unit (TEU container) kilometer.
