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. Financial Institutions use the GHG Rating to minimise or mitigate lending risk and to develop more sustainable practices. As the trend towards sustainable investment grows, financial institutions increasingly factor sustainability into their lending criteria.

Energy efficient vessels often have lower fuel costs and better chartering potential, which can ensure greater return on investment over the lifetime of the vessel. In addition, a more efficient vessel may align more closely with an organisation’s Corporate Social Responsibility (CSR) requirements. The GHG Rating providing a standard framework for measuring the efficiency of an investment portfolio and the ability to track changes over time

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. Financial institutions 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 financial institutions 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 in your portfolios, which allows the development of a baseline of emissions and an overall carbon-emissions target.


GHG Rating advantages

Check out the advantages for you
Sustainable investments

Banks are provided with an opportunity to reduce their risk by using the GHG Rating to identify and finance energy efficient assets. This is especially significant given the current over-supply of vessels in the market and the typical 25-30 year investment horizon.

Better returns

The GHG Rating can also be used to map the correlation between investment risk and vessel employment as an increasing number of charterers seek out more efficient vessels. An energy efficient vessel has lower fuel costs and better chartering potential, which may lead to a higher initial asset value and a longer period of economic depreciation.

Access more data

Efficiency data is also being used in credit-approval processes for vessel purchases, sustainable finance assessments for retrofit projects, with banks citing efficiency as a key indicator for a vessel’s profitability.
