GHG Rating

RightShip’s GHG Rating rates the emissions output of commercial vessels on a scale from A (most efficient) to E (least efficient). The gold standard for emissions comparison in the shipping industry, it is the first rating to incorporate EEXI values alongside EVDI and EEDI. It works by calculating and comparing a vessel’s designed efficiency against peer vessels of similar size and type using a speed-corrected methodology.

Vessels at anchor, loading and unloading produce large volumes of greenhouse gas emissions, impacting ports and terminals and their surrounding local communities. The GHG Rating gives ports the ability to assess the emission profile of any vessel in their port, enabling them to develop effective decarbonisation strategies such as port incentive programmes to attract more efficient vessels.

GHG rating features

Simplified decisions

The GHG Rating takes inputs from IMO standards, regulatory indices, and public, third-party, and proprietary data sources to allow best practice environmental vessel selection processes.

Standardised approach to decarbonisation

Speak the same language as your customers and suppliers by using the GHG Rating, easily understood and used by all players in the industry to decarbonise their supply chain.

Reduce supply chain emissions

Quickly identify vessels standing out from others in their peer group through global and fleet wide benchmarking, and develop strategies to attract the most energy efficient vessels to call at your port or terminal.

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.

The data RightShip provides is so critical for us – a trusted source of information and an integral part of our accounting process. MEP has enabled us to communicate confidently and transparently, and we’d encourage others to get on board and do the same.


GHG Rating advantages

Part of due diligence

Seamlessly integrate our GHG Rating with our vessel screening, vetting and other due diligence products, to ensure you meet industry emissions reduction targets with Environmental, Social and Governance (ESG) and Corporate Social Responsibility (CSR) targets.

Develop incentives

Join pioneering ports such as Canada’s Port of Quebec and Prince Rupert Port Authority who use our GHG Rating to offer incentives for more efficient ships, reducing CO2 emissions and other air pollutants in port while increasing cargo volumes and throughput.

Healthier communities

Improve stakeholder relations and generate significant social capital within local communities, thanks to the health benefits for residents from reduced emissions.
