GHG Rating

The shipping industry is changing rapidly. Increasingly, we are seeing new technology that can be used to reduce emissions. Battery-powered ships and alternative fuels are impacting the way we do business and reducing emissions in the process. 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, the RightShip GHG Rating has changed the way vessel operators benchmark their vessels and demonstrate the benefits of investing in efficiency.

RightShip’s GHG Emissions Rating was developed in response to the growing trend of global CO2 emissions reductions and customer demand for practical solutions. It has been designed to highlight and reward those who prioritise efficiency in the design of their vessel. The GHG Rating is a dynamic model, meaning a vessel’s GHG Rating moves relative to the changing market. By using the GHG Rating benchmarking you can easily compare your vessels at a fleet, sector or global level and design a sustainability strategy that means you always have a market advantage through your investments.

The GHG Rating compares a ship’s theoretical CO2 emissions relative to peer vessels of a similar size and type using an easy to interpret A – G scale. 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. Those who do the right thing are rewarded, with their results clearly displayed in our platform data, increasingly the likelihood that their vessel will be an attractive charter option.
