Green House Gas Rating

The maritime industry's gold standard for emissions comparison, RightShip's Green House Gas [GHG Rating] provides an independent assessment of vessel design efficiency.

Understanding the GHG Rating

RightShip rates vessels on a scale from A to E. GHG Rating combines EEXI, EVDI, and EEDI data with a speed-corrected methodology to deliver a fair and consistent benchmark across the global fleet. This enables owners, charterers, financiers, and other stakeholders to make more informed decisions that support decarbonisation across the maritime supply chain.

Why the Industry Trusts the GHG Rating

 

ghgrating1-06

Trusted Industry Benchmark

Recognised across the maritime industry, the GHG Rating provides a common framework for comparing vessel efficiency through an independent and consistent methodology.


ghgrating2-07

Greater Transparency for Stakeholders

A clear A–E rating gives owners, charterers, financiers, and supply chain partners a transparent view of vessel efficiency performance.


ghgrating3-08

Recognition of Efficiency Improvements

Investments in vessel design enhancements, energy-saving technologies, and efficiency upgrades are visibly reflected within the rating, helping organisations demonstrate progress.


ghgrating4-09

Simplified Sustainability Decisions

Complex efficiency and emissions data are translated into a single, easy-to-understand metric that supports vessel selection, fleet planning, and sustainability strategies.

Support Commercial and Investment Outcomes

Consistent benchmarking helps identify more efficient vessels, reduce emissions exposure, and inform chartering, financing, and portfolio management decisions.


Frequently Asked Questions

How does the GHG Rating differ from the IMO’s CII?

While both use an A–E scale, they measure different aspects of vessel efficiency. The IMO Carbon Intensity Indicator (CII) reflects a vessel’s actual operational performance over a reporting period, whereas the RightShip GHG Rating evaluates a vessel’s modelled efficiency under standardised conditions within a peer group. This approach enables consistent comparison of vessels based on their relative efficiency, independent of specific trading patterns.

What is the impact of Engine Power Limitation (EPL) on a rating? RightShip applies a standardised, speed-normalised methodology that enables vessels to be compared consistently within a peer group. This approach reduces the impact of short-term operational measures such as Engine Power Limitation (EPL) or ShaPoLi on the rating, ensuring the GHG Rating reflects underlying relative efficiency rather than temporary operating conditions.
How can a vessel improve its GHG Rating?

The rating is dynamic and reflects a vessel’s current technical state. Owners can improve their rating by investing in energy-saving devices (ESDs) or propulsion upgrades. Once these retrofits are verified by a classification society and the documentation is submitted to RightShip, the rating is recalculated to reflect the improvement. 

Why should I pro-actively make a GHG Verification submission?

Verified vessels benefit from a more efficient vetting process. While unverified ratings use available S&P Global data and IMO assumptions, a "Verified" status confirms accurate performance data. This provides greater confidence to charterers and financiers, positioning a vessel at a competitive advantage.
