CSR

Take sustainable action to protect what matters

At DEF, our mission is to protect property and people. This responsibility comes with a strong commitment: to contribute to development that is more sustainable, more people-centred, and more responsible.

 

Since 2014, DEF has actively supported the Ten Principles of the United Nations Global Compact, which address human rights, labour standards, the environment, and the fight against corruption.

Protect the environment

Since 2011, DEF has formalised its environmental commitment through ISO 14001 certification, an international standard that serves as the benchmark for implementing an environmental management system.

ISO 14001 certification provides DEF with a framework for structuring its approach to balancing its business operations, environmental concerns, and economic imperatives.

A Health & Safety policy at the heart of our commitments

At DEF, occupational health and safety is a top priority, supported by a structured approach that is ISO 45001-certified. Guided by the goal that “everyone returns home safe and sound,” our policy aims to protect the physical and mental well-being of everyone.

It relies on building managers’ skills, enhanced preventive measures, and psychological support that is accessible to everyone. This approach also extends to our subcontractors, in order to share our requirements and best practices throughout our entire supply chain.

At DEF, health and safety are fully integrated into our strategy: a key driver of sustainable performance and workplace well-being.
