Health and safety: our first priority

One Safety : a common language for a common culture

In 2022, we launched a transformation plan called ENGIE One Safety to harmonize the prevention of occupational risks across the Group worldwide. This initiative is built around three fundamental pillars: “No life at risk” for physical safety, “No mind at risk” for mental health and quality of life at work, and “No asset at risk” for the integrity of our industrial assets.The program brings all our teams together around shared standards, tools, training programs and feedback mechanisms to strengthen our collective learning.

Since 2026, the No Mind at Risk pillar has been reinforced with the upcoming publication of a new standard introducing three requirements to be implemented across all ENGIE entities by the end of 2027: detection, managerial engagement, and reporting & learning.

This development now structures the prevention of psychosocial risks around a more systematic approach:

• Detection: Each entity must rely on shared tools (annual psychosocial risk survey, indicators, weak signals, etc) to quickly identify risks that may impact mental health or operational vigilance.
• Managerial engagement: Managers are now required to actively contribute to this prevention effort, notably through dedicated safety rituals and specific training.
• Reporting & learning: Serious psychosocial events must be reported within 30 days and analyzed using a harmonized methodology in order to promote collective learning across the Group.

These new requirements strengthen ENGIE’s ambition to treat mental health as a core element of sustainable performance, alongside physical safety and asset integrity.

ENGIE’s health & safety approach

Major risk management: 9 lifesaving rules

Each ENGIE entity establishes a detailed risk mapping to identify, as close as possible to operations, the dangers specific to its activities. This approach is reinforced by the systematic application of 9 lifesaving rules, non-negotiable standards designed to prevent serious accidents linked to high-risk activities.These form the essential foundation of the behaviors expected from everyone, in all circumstances.

In addition, we address high-potential incidents (HiPo): events that, under slightly different circumstances, could have led to serious or fatal consequences. Analyzing them allows us to act on these warning signals before an accident occurs.

Shared vigilance: Looking out for one another

ENGIE promotes a culture of shared vigilance, where everyone is encouraged to report dangerous situations, prevent deviations and take care of their colleagues’ safety.

Learning to detect weak signals and having the confidence to share them is a powerful act of prevention that strengthens our collective ability to avoid incidents.

The life-saving minute: Taking a moment to think

Before starting any activity, every employee is invited to take “the life-saving minute” – a brief pause to assess the environment, verify that the necessary resources are in place, and ensure that all safety conditions are met.

The stopping point: Knowing when to say stop

ENGIE encourages everyone to fully exercise their right – and their duty – to use the word stop. In case of doubt, observed deviation or changing conditions, anyone can interrupt a task without hesitation or prior justification. The ability to say “stop” at the right moment is one of the most powerful ways to prevent accidents.

Events and incidents: Acting on warning signals

The rigorous treatment of events and incidents, particularly those with a high potential severity (HiPo), lies at the core of our approach. These situations – which could have had severe consequences in another context – are systematically analyzed to identify their root causes. Turning these warning signals into concrete actions helps prevent recurrence and sustainably raise the level of safety.

Committed leadership

Managers’ exemplary behavior is the driving force behind the transformation of our safety culture, with a clear objective: the lasting elimination of serious and fatal accidents for all workers, including our contractors. Between 2023 and 2025, a training and coaching program was rolled out for all managers to strengthen safety rituals (site visits) and promote a shared Occupational Health and Safety (OHS) culture. Performance is monitored by the Executive Committee through the analysis of accidents that have occurred and reports of dangerous situations or high-potential events. In the interest of transparency, this data is certified by the statutory auditors and reviewed by the Global Forum, our official international social dialogue body established under the 2022 Global Framework Agreement.

A commitment extended to our partners and contractors

The Group’s priority is to protect the health and safety of everyone working on our sites, our projects and at our customers’ facilities. Our requirements apply with the same level of rigor to contractors as to our own employees through a comprehensive collaboration process:

• Selection and qualification: Only companies demonstrating the highest prevention standards are authorized to work with ENGIE.
• Supervision and safety rituals: Every assignment begins with a systematic safety briefing and continues with rigorous on-site monitoring of ENGIE standards.
• Evaluation and progress: Partners are assessed on their ability to guarantee the safety of every individual. At the end of each assignment, a feedback process helps identify areas for improvement together.

ENGIE systematically provides a safety briefing during which key safety principles are clearly explained to workers, both in theory and in practice.
