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.


Rocky Mountain Institute’s Shipping Efficiency Operation was originally launched in 2010 by Carbon War Room—a global non-profit founded by Sir Richard Branson and a group of likeminded entrepreneurs that merged into RMI in 2014. Rocky Mountain Institute (RMI) is an independent nonprofit founded in 1982 that transforms global energy use to create a clean, prosperous, and secure low-carbon future. RMI engages businesses, communities, institutions, and entrepreneurs to accelerate the adoption of market-based solutions that cost-effectively shift from fossil fuels to efficiency and renewables. RMI has offices in Basalt and Boulder, Colorado; New York City; Washington, D.C.; and Beijing.

Together with RightShip, Rocky Mountain Institute manages the GHG Emissions Rating, which 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.
