Shipping Efficiency is an initiative launched by the Carbon War Room and RightShip to increase information flows around the energy efficiency of international shipping and ultimately help reduce the environmental impacts of the world's shipping fleet. enables anyone to tell an efficient, low-emission ship from a less efficient one, for the first time. Using a simple search function, users can pull up a GHG Emissions Rating for around 76,000 existing ships, including the majority of the world's container ships, tankers, bulk carriers, cargo ships, cruise ships and ferries.




Steering the way in safety and environmental sustainability, RightShip is the world’s leading maritime risk management and environmental assessment organisation.

RightShip’s comprehensive online risk management system is accessed 24/7 through, using up-to-the-minute data from over 76,000 ships and thousands of maritime companies to deliver instant, reliable marine risk and environmental sustainability assessments. RightShip also provides clients with hosted ship vetting, as well dry bulk and tanker inspection services.

RightShip Qi, the organisation’s new online platform, is launching in 2016. Qi brings all the benefits of big data and predictive analytics to maritime risk management, providing users with sophisticated, real-time vetting insights and enhanced reporting capabilities.

RightShip used its years of maritime sector experience in online risk rating algorithms to develop the Greenhouse Gas (GHG) Emissions Rating. Partnering with the Carbon War Room on, the GHG Rating enables customers to include the growing importance of carbon emissions in their vessel selection process. It is now used as a vessel selection tool for 1 in every five ships chartered, equating to over 2 billion DWT per annum.

Carbon War Room

Carbon War Room (CWR) was founded in 2009 as a global non-profit by Sir Richard Branson and a group of likeminded entrepreneurs. It intervenes in markets to accelerate the adoption of business solutions that reduce carbon emissions at gigaton scale and advance the low-carbon economy.

CWR merged with Rocky Mountain Institute (RMI) in 2014 and now operates as an RMI business unit. The combined organization engages businesses, communities, institutions, and entrepreneurs to transform global energy use to create a clean, prosperous, and secure future. The combined organization has offices in Snowmass and Boulder, Colorado; New York City; Washington, D.C.; and Beijing.

Carbon War Room launched the Shipping Efficiency Operation in 2010. Since then, it has worked with RightShip to develop the GHG Emissions Rating and make it publicly available at The Rating ranks vessels against others of a similar type and size on a simple A to G scale, from most to least efficient. It is now used by charterers to shift a fifth of the world's shipped tonnage to more efficient ships annually and by other shipping stakeholders, including ports and banks.
