Environmental management systems

Environmental management systems


In 2021, 363 audits were carried out in relation to HSEQ issues


In 2019 Snam started to update existing certifications, in accordance to the new standards (ISO 14001:15 and ISO 9001:15)


Snam’s policy is to minimise the environmental impact of its activities, applying, where technically and economically feasible, the best available technology and implementing specific management systems and procedures

Attesting management systems means to be in compliance with regulations ant to improve processes

To continuously improve its environmental performance, Snam actively manages its commitments with regard to prevention, certifying the management systems of its operating activities in accordance with the reference standard UNI EN ISO 14001 and with Snam's environmental policy.

Snam’s environmental policy, promoted by the CEO and adopted by all group companies starting from executive management, extends to the entire value chain and applies: to all the production phases of every product (e.g. production of natural gas compressors) and services (e.g. transportation of natural gas), including distribution and logistics phases, in addition to related waste management; to each site and building; all the relationships with external stakeholders; all mergers and acquisitions; every key business partner (including partners related to non-managed operations, joint ventures, outsourcing or third-party producers); every supplier, including service and contractor suppliers; all due diligence processes as well as Merger and Acquisition processes.

For what concern the environmental management systems, those should be based on two guiding principles: compliance with regulatory obligations, and the improvement of the corporate response to environmental issues.

The purpose of these systems is to:

  • identify and control the main environmental issues;
  • coordinate all activities with an environmental impact;
  • assign specific responsibilities for their implementation.



Deming Cicle



In order to systematically address environmental issues, Snam identifies and analyses the main problems and only then defines strategic and operational measures to manage them. Once this process is completed, the efficiency of these measures is assessed and further weak points are analysed, as necessary. Based on this control phase, the planning cycle then starts over again with the definition of new objectives.

Snam manages the achievement of these objectives through the process explained above, called the “Deming cycle” or “Plan, Do, Check, Act”.


Management system certifications:

Also in 2020 Snam implemented all the activities necessary to extend the management system certifications to the new companies entering the scope of consolidation and to maintain and update other existing certifications, in accordance to the new standards (ISO 14001:15 and ISO 9001:15).

To check the effectiveness of the management systems, an internal team made up of 7 auditors carries out audits on health, safety and the environment: in 2021, 363 audits were carried out, 316 at the various companies of the group (of which 98 conducted by an external team) and 47 at contractors working on construction sites.

Main certifications ISO 14001 for  Snam group can be seen in this table.
