ISO 14001 standard: Environmental Management

The ISO 14001 standard on environmental management aims to enable companies to take environmental issues into account in all their activities, and thus improve their environmental performance.

As part of its commitment to environmental responsibility, the Group encourages environmental management certification for all its activities impacting or dependent on the environment, i.e. all Group activities excluding tertiary, commercial or trading activities. For activities covered by this standard, the Group leaves it up to each entity to decide whether or not certification is appropriate, and if so, how.

At the end of 2025, 73.4% of revenues concerned by this standard were covered by ISO 14001 certification, EMAS (Eco Management and Audit Scheme) certification (the enhanced European translation of ISO 14001 certification), or other equivalent external or internal certifications.

Here are a few Group entities certified to ISO 14001.

ISO 27001: Information security management

The ISO 27001 standard for information security management aims to secure information essential to a company’s business, and to guarantee access to shared information.

Aware of the risks associated with the cybersecurity of data and information systems, and of the growing number of regulatory changes in this area, ENGIE’s operating entities are using the ISO 27001 standard as a basis for certification procedures, sometimes at the request of their own customers, sometimes in application of national regulations specific to critical infrastructures.

Here is an example of a Group entity certified to ISO 27001:

ISO 37001 standard: Anti-corruption management

The ISO 37001 standard for anti-corruption management aims to prevent, detect and deal with corruption issues that may affect the company.

As part of its integrity approach, ENGIE attaches particular importance to the fight against corruption, carries a strong zero-tolerance message and carries out external audits of its system. As early as 2015, the Group obtained certification of its anti-corruption system issued by Mazars and ADIT. In 2018, the Group introduced annual audits of ISO 37001 certification, which has been renewed every year since. All these audits are carried out at Group level and in several operating entities representative of its activities.
