Our commitments

Quadrilatère recognizes its responsibility for the impacts of its decisions and activities on the society and on the environment. From 2020, the company is committed to maintaining its growth objectives, while improving its CSR (Corporate Social Responsibility) report. To orchestrate this, Quadrilatère appointed a Director of Sustainable Development, and created an internal CSR committee intended to rethink, suggest and implement tangible improvements.

Since 2021, Quadrilatère’s CSR policy has been subject to rating by EcoVadis, a platform for evaluating CSR performance and responsible purchasing (ecovadis.com). In 2024, Quadrilatère obtained a score of 74/100, corresponding to the gold medal, which places us in the top 5% of companies evaluated by EcoVadis.


At Quadrilatère, taking into account the well-being of our users is not an option, but an obligation. The challenge for our customers today is to improve the quality of the working environment of their employees, to offer them comfortable workspaces, beyond a good chair, a beautiful desk or sofa. We are talking about acoustic comfort, light and functionality.

In order to “set an example”, Quadrilatère has had its head office certified by the “Osmoz Aménagement” label from Certivea.

On the program: environmental health (air quality, visual, acoustic, thermal atmosphere, exposure to electromagnetic waves), lifestyle, balance between private and professional life, communication and social ties, functionalities, collaborative approach (Repository accessible on request via the contact form on the site www.certivea.fr ; certified characteristics available on www.certivea.fr).

Quadrilatère is also an associate member of IDET, the largest professional network in France dedicated to Work Environment managers. (www.idet.fr).

“If the employees feel good, in addition to being good ethically, it perfectly meets the societal mission of the company.”


Quadrilatère is committed to implement an eco-responsible policy within its company and aims to develop this approach within its projects.

Quadrilatère carried out its first carbon assessment in 2021, on all the goods, services and activities operated by the company (3 scopes). As we suspected, our construction sites represent 96% of our GHG emissions. On the strength of these conclusions, and in partnership with our consulting firm BL Evolution, Quadrilatère’s internal CSR committee is now working to define a real strategy for reducing our emissions.

At the same time, Quadrilatère being convinced that every gesture counts, the company continues to limit the use of the plane for the business trips of its employees and to encourage soft mobility.

Within its premises, Quadrilatère has implemented a number of actions aimed at reducing its consumption of paper, water and electricity.

In order to reduce its waste as much as possible, the company is equipped with durable dishes, 2 refrigerators and 2 dishwashers. Coffee and tea are purchased in bulk. For the management of its internal waste, Quadrilatère calls on Tricycle Environnement, which collects its disposable masks, coffee grounds and paper/cardboard.

Since March 2022, Quadrilatère has extended its contract with Tricycle to the reuse of its construction waste. Differentiated bins are installed on site at each start of construction to collect scrap metal, plastic, ordinary industrial waste, electrical and electronic waste, cardboard/paper, rubble, wood, plaster and tiles.

For its projects, Quadrilatère recommends the use of natural and eco-responsible materials, from clean industry or from the recycling industry, verifies their origin and consults the existing Environmental and Health Declaration Sheets. These products are referenced in an e-materials library, supplied by our Materials Manager. The products are then implemented by its installers and subcontractors, in accordance with the certificate obtained by the finishing materials, and according to the objective of the ecological label to be achieved on the projects.

Likewise, for fittings and furnitures, Quadrilatère verifies the origin of materials, and favors factories located nearby in order to limit CO2 emissions caused by transportation. A CSR furniture catalog, referencing eco and socially responsible manufacturers and products, is currently being drafted.


Quadrilatère pays particular attention to the working conditions of its employees and claims the fairest possible employer / employee relationship : job stability, development opportunities, parity, diversity, skills development, dialogue and transparency regarding the objectives and results of the company.

Since 2020, employees have also been associated with the economic performance of the company through a Company Savings Plan.
