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.
GHG Rating

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
Transparency
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.
Benchmarking
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.



GHG Rating advantages
Part of your due diligence
Seamlessly integrate the GHG Rating with RightShip’s vessel vetting to align industry emissions reduction targets with your ESG and CSR targets, allowing you to screen for only the most efficient vessels.
Increased throughput
Ability to increase cargo volumes (throughput) while maintaining or reducing overall CO2 emissions.
Trend setter
Improved stakeholder relations generating significant social capital within the local community, due to the health benefits for local residents from the reduced emissions. Recognition as a leader in the maritime industry, pioneering the growing global movement to increase focus on emissions and efficiency.
We’ve used RightShip to ensure the vessels we use are safe and environmentally sound, so it was a logical step to ask the team to help us measure our scope 3 emissions. Working with them is very straightforward and we are confident in the accuracy and reliability of the results. There are very few scope 3 data sources and, as far as we are aware, there is no other agency able to deliver this level of accuracy for ocean transport.
RightShip, the ship approval system used to verify vessel efficiency, has confirmed the fuel savings Odfjell has achieved using MAN Diesel & Turbo’s Kappel Propeller upgrade package. After the upgrade, the vessels are amongst the most energy efficient chemical tankers in the world, and achieve the highest score on the RightShip’s energy rating, A+.
Until 2016, our scope 3 emissions were estimated but that’s no longer good enough. We need to understand our emissions so we can benchmark them against other shippers and control them effectively. RightShip allows us to do that.
We’re proud to be accelerating the shipping industry’s movement toward greater efficiency and sustainability using RightShip’s GHG Emissions Rating. Since launching our Green Wave vessel incentive program in 2014, RightShip has been an exemplary qualifying measurement that has allowed vessel charterers and owners to take advantage of significant discounts to harbour dues at the Port of Prince Rupert. The support we have received through our partnership with RightShip has been integral to the success of our program. Our recognition of environmental performance is encouraging the adoption of similar practices across the global shipping industry.
By using more-efficient ships, we are gaining cost efficiencies and furthering our efforts to reduce Mosaic’s carbon footprint. Given the success of GHG Emissions Rating vetting, we are reviewing options to also exclude F-rated vessels. Emissions from shipping currently represent less than 5 percent of Mosaic’s carbon footprint.
