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. Ports and Terminals use the GHG Rating to create cleaner environments through benchmarking emissions and environmental incentive programs. It provides a proven emissions reduction strategy and a tangible way to reach your ESG goals.

Positioned – quite literally – at the forefront of the effects of global warming and rising sea levels, ports are increasingly aware of the impact of CO2 emissions. Pioneering ports such as Canada’s Port of Vancouver and Prince Rupert Port Authority now use RightShip’s GHG Rating to offer incentives for more efficient ships, reducing CO2 emissions and other criteria pollutants in port.

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. Ports and terminals 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 ports and terminals 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 per vessel call, which allows the development of a baseline of emissions and an overall carbon-emissions target.
