CMA CGM slashes CO2 emissions by 50 percent in 10 years

French shipping giant CMA CGM announced a 50 percent improvement in its CO2 performance for its owned fleet. Thanks to an efficient environmental policy sustained by deploying innovative solutions, this success was accomplished in 10 years.

Today, a container emits approximately 60 grams of CO2 per kilometer, compared to 120 grams in 2005. The group’s best-performing ships emit 37 grams of CO2 per container transported, such as the CMA CGM Bougainville that can carry up to 200,000 tons of goods in 18,000 TEUs.

By redesigning its vessels structure, CMA CGM improved their hydrodynamics, reducing fuel consumption and CO2 emissions.

The following technical innovations have been implemented on the CMA CGM fleet:
- New bulbous bows have been installed in order to adapt the hydrodynamics of the ships to the new reduced sailing speed.

- Propellers have been optimized to gain efficiency following the decrease in engines' power: their diameter has been increased and a blade removed.
- A new twisted leading edge rudder improves water flow and thus the hydrodynamic performance of the vessel.

The carrier develops and uses new environmentally friendly containers, which save 1 to 2 tons of fuel
per day, thereby preventing emissions of 3 to 6 tons
of CO2.
