DCNS commits to environmental protection

DCNS considers that addressing environmental issues contributes to the company’s performance.

This is clear for the production sites, all located close to the coast or a river, and is a question of coherence when the Group is positioned on the marine renewable energy market. It is also a competitive advantage when this concern is integrated into the products and activities.

DCNS is developing centrally the Group’s strategy within the Performance and Quality department, and is involving all employees in this initiative, capitalising on a network of 15 environment managers distributed across France.

Since 2008, all DCNS sites and activities located in France are ISO 14001 certified.

To illustrate its commitments, DCNS has set ambitious goals for 2015 – 2017.

First objective: zero environmental accidents

The management of industrial risks is our priority. There are 150 industrial installations spread across all our sites. None are classed SEVESO. They are duly regulated and regularly inspected by the authorities. Their associated risks have all been identified and analysed, and the risk-control measures have been implemented.

Since 2012, there have been no environmental accidents with significant impact on the environment and incidents resulting in a temporary impact (thresholds briefly exceeded or limited localised pollution) are falling constantly.

DCNS’s primary objective is to avoid accidents altogether.

Second objective: 50% of programmes pro-actively embracing eco-design

Eco-design is at the heart of our environmental policy, representing a competitive advantage. Over and above the purely regulatory compliance aspect, it firstly allows an increase in the attractiveness of products through energy efficiency and the reduction of waste and emissions. It also allows the preparation of their recycling under the best possible conditions through the selection of the most appropriate materials and a thorough awareness of dangerous substances. The Group’s objective is to ensure that one in every two vessel programmes is particularly pro-active in this respect.

Third objective: reduce environmental impact

The emission of greenhouse gases (GHGs)

To contribute to the fight against global warming, DCNS has decided to reduce its greenhouse gas emissions by 10% within three years. To reach this goal, reduction initiatives are being conducted in the following three main areas:

  • Gas (Scope 1) and electricity (Scope 2) consumption.
  • Business travel (Scope 3).
  • Home-work commuting (Scope 3).

ENV 4 GHGNote: An objective of a 10% reduction in gas and electricity consumption has been set for 2015-2017 while each site will have its own Company Mobility Plan by the end of 2016.

Concerning VOC (Volatile Organic Compounds), sulphur dioxide (SO2) and nitrogen oxide (N0x) emissions, analyses are performed annually and a national working group has been set up to propose ideas for improvements.


In application of the principles of the circular economy, DCNS is seeking to reduce and better recycle its waste. An overall recycling goal (materials and energy) has thus been set for the entire Group (≥ 70%) with a minimum per site of 50%.

Water consumption

The quantity of water used for installation cooling is continuously falling each year with most installations now operating on a closed circuit.

The slight increase observed in 2015 is due to leaks, which were detected and repaired with some delay.

Only the Indret site continues to pump large volumes from the Loire when thermal-machine tests are performed on the site; the volumes consumed can thus vary significantly from one year to another.

The DCNS Group has always been naturally interested in biodiversity questions because of the location of its sites and the nature of its activities. Each industrial site is located in proximity to a natural land or marine reserve, listed as a result of the rarity or fragility of the indigenous species, both fauna and flora, and their habitats.

In each of these cases, the industrial and economic decisions are not taken to the detriment of environmental protection, and both dimensions are taken into account, addressing the needs of each.

Special attention is given to marine renewable energy (MRE). This is a recent and fast-developing activity for which it is not always possible to foresee the impact on the environment. This is why for each of its projects DCNS studies the living habitat and the activities, to perform impact studies and adapt the project with the aim of protecting the environment and ensuring societal acceptability.
In this domain, DCNS is a partner in several projects aimed at improving the knowledge of habitats, in particular with the “France Energies Marines” institute.
