CMA CGM is Proud To Act

The CMA CGM Group is a world leader in transport and logistics committed to energy transition. We work daily to reduce the environmental impacts of our maritime and land activities. We do this with a pioneering mindset: to act today on the basis of the best solutions available.


Climate Change

Climate change is a major issue for maritime transport. The burning of the fuel oil consumed by ships which accounts for 88% of the Group’s greenhouse gases, the main source of greenhouse gas emissions.

In 2015, the Group met its 2005 objective of reducing CO2 emissions per TEU-km by 50%, and a new objective has been set: – 30% of CO2 per TEU transported by 2025. In 2017, CO2 emissions per container transported decreased by 10% vs. 2016.

Changing Ship Propulsion

Given the power requirements of large container ships, there are few alternative means of propulsion to fuel oil that have reached sufficient technical and industrial maturity. The CMA CGM Group invests in and is involved with all solutions that offer serious potential for emissions reduction.

A resolute investment in LNG technology

The CMA CGM Group has chosen to invest heavily in LNG technology by ordering 20 gas-powered vessels including 9 giant 23,000 TEU ships.

These vessels represent a first-order technological innovation that limits the impact of maritime transport on the environment. On average, they emit up to 20% less CO2 than traditional-powered vessels. In addition, LNG emits virtually no air pollutants and thus preserve air quality.

LNG is the best technology available. We are investing in it resolutely rather than waiting for a better one to mature.

Conclusive tests on 2nd generation biofuels

Second-generation biofuels produce marine fuel consisting of forest residues and used oil and not food crops.

These new biofuels reduce CO2 emissions by 80-90% over the entire so-called “well-to-propeller” cycle.

In 2019, CMA CGM conducted a series of biofuel tests in partnership with one of its preferred customers, IKEA. Since these tests proved conclusive, CMA CGM has selected Shell to supply tens of thousands of tons of second-generation biofuel and will offer new biofuel services to its customers in 2020.


The new IMO Low Sulphur regulations involve lowering the sulphur content of fuels used in maritime transport to one seventh current levels, thereby reducing sulphur oxide emissions globally by 85%. Since January 2020 CMA CGM is in compliance with this new regulation and goes even further.

By investing in LNG technology

Liquefied natural gas can eliminate 99% of sulphur oxide (SOx) emissions, but it also reduces fine particulate emissions by 99% and nitrogen dioxide emissions by 85%. Very significant progress in improving air quality, especially for people living near coasts and port cities.

By equipping its ships with smoke treatment systems

CMA CGM implements an extensive equipment plan for its ships by installing smoke treatment systems called Advanced Air Quality Systems. We have chosen to use hybrid technology that allows these devices to operate in a closed loop and to recover filtration residues at the dock rather than discharging them at sea.

By using new types of low sulphur fuel oils

CMA CGM will also use new types of fuel oil with a sulphur content of no more than 0.5%. This involves significant operational changes such as training crews in the use of new fuels and modifying supply chains.

By investing in dockside electrical connections

A significant proportion of a ship’s air pollutant emissions are related to the operation of engines to generate shore-based electricity. CMA CGM equips its ships with “cold ironing” devices that connect them to the land-based electricity grid.


CMA CGM will not use the Northern Routes

The Northern sea route which runs along Russia’s polar coast and connects Asia to Europe has now been rendered navigable by the effects of global warming and the melting of ice. Rich in unique and still unknown biodiversity, the Arctic is essential to the regulation of currents and the global climate. Its massive use would pose a real danger to the exceptional natural ecosystems of this part of the world due in particular to the risk of accidents and oil pollution or collision with cetaceans.

In order not to further jeopardize this fragile environment, Rodolphe Saadé, CEO of the CMA CGM Group has decided that none of the 500 vessels of the CMA CGM Group would use the Northern Routes.

Control of the transfer of invasive species

Ballast tanks on either side of a vessel are filled with seawater and serve as ballast to ensure the stability and integrity of the vessel.

Ballast water carried by container ships may contain living organisms that, if released in another environment, can disrupt the balance of flora and fauna.

In 2015, CMA CGM began equipping its vessels with a ballast water treatment system. This innovative system filters ballast water using UV rays when water is collected and discharged in order to remove living organisms that are harmful to marine life.
