CSL Group’s four-year marine B100 trial makes significant decarbonization strides

In Canada, CSL Group announced a significant milestone in its Great Lakes biofuel program – one of the longest-running initiatives of its kind in the maritime industry.

With a cumulative 75,000 running hours on B100 biofuel over the past four years, CSL ships have made significant strides in supporting decarbonization efforts by replacing 55,000 metric tons of fossil fuel with biodiesel and avoiding 156,000 metric tons of CO2.

CSL initiated its biofuel journey in 2019 with a B50 blend, gradually progressing to B80 and, in 2020, running two ships on B100 – pure biodiesel produced entirely from waste plant material unrelated to food production. Since 2021, eight CSL vessels have run continuously on B100 for five to eight months per year, proving the technical viability and practicality of biofuel in reducing well-to-wake GHG emissions and meeting regulatory limits for SOx and NOx emissions.
