The CSL Group, a maritime leader, celebrates success in its biofuel program, having logged 75,000 hours on B100 biofuel, reducing 156,000 metric tons of CO2 emissions across their fleet. They advocate for government support to sustainably integrate biofuels and urge industry-wide adoption to curb marine emissions.



The CSL Group, renowned for responsible marine services, hails a significant milestone in its Great Lakes biofuel program, achieving pioneering strides in decarbonizing maritime operations. Over four years, CSL vessels accumulated 75,000 hours on B100 biofuel, substituting 55,000 metric tons of fossil fuel and averting 156,000 metric tons of CO2 emissions.

Louis Martel, CSL President and CEO, emphasizes their commitment: "We've shifted from biofuel trials to its active deployment, exemplifying our efforts to reduce carbon in operations." In 2023 alone, CSL's biofuel fleet hit a pinnacle, consuming 16,400 metric tons of B100, resulting in an 80 to 90% reduction in greenhouse gas emissions and evading 50,000 metric tons of CO2 across their Great Lakes fleet.

Initiated in 2019 with B50 blend trials, CSL's steady progress led to the use of B100, a pure biodiesel crafted from non-food-related waste plant material. Eight CSL vessels have consistently operated on B100 for substantial periods annually since 2021, demonstrating its efficacy in curbing GHG emissions, complying with emission regulations, and ensuring technical viability.

Mr. Martel envisions a biofuel-integrated future for their Great Lakes fleet, targeting eight vessels in 2024 and aspiring to expand this initiative fleet-wide. Despite biofuel's proven efficiency, CSL advocates for governmental backing to sustain its affordability. They call upon industry stakeholders to adopt sustainable practices in maritime transport.

CSL's biofuel program has significantly influenced industry standards and influenced organizations like the IMO, Classification Societies, CIMAC, and OEMs. Their pioneering data has propelled progress in biofuel integration within the maritime sector, fostering advancements in sustainable marine practices.

As the largest owner and operator of self-unloading ships worldwide, CSL remains committed to delivering cargo across continents. Their biofuel journey exemplifies a proactive approach toward environmental responsibility while steering the maritime industry toward sustainable horizons.


CSL's journey in biofuel adoption showcases not only an effective emissions reduction strategy but also a call for collaborative efforts between governments and industry stakeholders to mainstream sustainable practices in the maritime sector. Their pioneering efforts have set a benchmark, influencing global industry standards for a greener marine future.
