Developed by the maritime risk-management specialist RightShip and Carbon War Room, GHG Emissions Rating is a tool that uses an A-to-G scale to assess the efficiency of vessels, wherein A represents the most-efficient ships and G the least.

Mosaic, which charters around 130 vessels a year, will now eliminate all G-rated vessels for international shipping.

"Emissions from shipping currently represent less than 5% of Mosaic’s carbon footprint."

The Mosaic Company Sustainability director Neil Beckingham said: "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% of Mosaic’s carbon footprint."

The use of the GHG Emissions Rating and the A to G scale has increased by more than 450%, during the past two and a half years, Carbon War Room stated.

Mosaic and the other 24 RightShip charterers using the GHG Emissions Rating will also benefit from lower annual fuel bills and greenhouse gas emissions.

GHG Emissions Rating is also allowing shipping companies use the data held on each individual ship to calculate their carbon footprint from maritime shipping. The Mosaic Company uses this data for the assessment of their Scope 3 emissions reporting within CDP.
