GHG Rating

We want to reach a 50 per cent reduction in shipping emissions by 2050. RightShip’s GHG Emissions Rating provides a transparent method to assess the relative efficiency of vessels and compare a ship’s theoretical CO2 emissions relative to peer vessels of a similar size and type using the easy to interpret A – G scale. Those resisting the evolution risk an impact to their bottom line.

When you employ sustainability measures recommended by RightShip, you strengthen your market position. The GHG Emissions Rating is a systematic and transparent means of comparing the relative efficiency of the world’s shipping fleet. It is disrupting the market, putting those who use it out in front of their competition through increased transparency. In rating ships according to their efficiency, we enable users to make informed decisions about the sustainability of their supply chain.

Companies who have adopted policies to remove inefficient vessels from their supply chain are enjoying the economic and sustainability benefits flowing to their business. The GHG Rating has changed the way insurers think about the correlation between insurance risk and vessel employment as an increasing number of charterers seek out more efficient vessels. It provides a proven emissions reduction strategy and a tangible way to reach your ESG goals.

The GHG Rating is a dynamic model, meaning a vessel’s GHG Rating moves relative to the changing market. This allows you to easily monitor market improvements and keep your sustainability strategy relevant. As more nations place a price on carbon, the payoff for investing in energy efficient vessels will materialise and insurance firms and P&I clubs that continually invest in their sustainability strategy will have significant market advantage.

Features of GHG Rating for ports and terminals



The GHG Rating increases transparency in the shipping industry by ranking ships according to their energy efficiency and GHG emissions. Marine insurers can quickly and easily identify vessels standing out from others in their peer group, measuring the impact of vessels that will improve the emissions profile of their company.


Informed selection

Assists the maritime industry to transition to a low carbon economy through informed selection of more efficient ships. The clearly explained methodology provides easy to understand ratings used by all players in the industry and provides a market-based need for marine insurers to select companies who invest in essential energy saving equipment.



Compare the relative efficiency of vessels through global and fleet benchmarking, allowing you to fully understand your emissions profile and the emissions of your supply chain. Track emissions of vessels you insure, which allows the development of a baseline of emissions and an overall carbon-emissions target.
