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. The GHG Rating has changed the way charterers think about vessel selection and mitigate their emissions. It provides a proven emissions reduction strategy and a tangible way to reach your ESG goals.

The GHG Rating is a dynamic model, meaning a vessel’s GHG Rating moves relative to the changing market. This allows you to easily monitor market improvements, keep your sustainability strategy relevant and always drive positive change through your vessel selection process.
