Measures for preventing, reducing and rectifying air, water and soil pollution

External certifications (e.g. ISO 14001) and in-house standards (Ecosite label and the Colas checklist) are the main resources available to the Bouygues group’s operating units for limiting the impacts of its activities, especially all forms of pollution (waste along with air, water or soil pollution). In addition, Bouygues and its business areas promote high environmental quality benchmarks to customers with a view to curbing such pollution.

Bouygues Construction

At Bouygues Construction, action to reduce environmental impacts is covered by the ISO 14001 management system. This is reinforced by Ecosite, most notably through the “hazardous materials”, “air” and “bodies of water” standards, each of which lays down minimum requirements with which to comply.

Worksite-related environmental standards are supplemented by specific preventive measures and equipment requirements for site accommodation. Lastly, within each entity, emergency procedures exist in the event of pollution incidents that put in place the appropriate remedial action.
In addition, a database keeps a list of hazardous materials and the associated preventive measures, as approved by the occupational health expert.
Bouygues Construction is also involved in several R&D projects investigating ways in which to limit wastewater pollution in operations. For example, a phytoremediation process is undergoing experiments, and a process for neutralising the effects of road salts is being studied.

Bouygues Immobilier

Bouygues Immobilier’s commitment is chiefly based on the HQE® (High Environmental Quality), LEED® and BREEAM® certifications:

  • in the design phase: HQE® aims to improve the environmental quality of new and existing buildings,
  • in the construction phase: an HQE® worksite must ensure that all types of pollution (air, water or soil) are curbed.

The implementation of the Clean Worksite charter helps to guard against and reduce air, water and soil pollution. For its office developments, Bouygues Immobilier uses LEED® and BREEAM®, which have a separate Pollution and Emissions category for air, water and soil pollution caused by a building throughout its lifecycle.

Bouygues Telecom

In the context of classified installation reporting requirements for its office buildings, Bouygues Telecom regularly ensures that it complies with requirements relating to air-conditioning systems and generators.

 Under the HQE® initiative, Bouygues Telecom monitors air quality in its office buildings. No plant protection products are used in the upkeep of grounds on its sites.


At Colas, the basic documentation for all environmentally certified sites contains an environmental analysis report, monitoring charts and prevention plans (especially for pollution management, where this is identified as a significant issue).

These documents are assessed during reviews by management, which analyse improvements in environmental performance and control of impacts. No accident with a serious effect on the environment occurred during the year under review.


In its guidelines to maintenance service providers, TF1

bans the use of substances that are harmful to the environment.
