Galsi considers protection of the environment to be a fundamental social value, and believes in the compatibility of "business growth" and "respect for the environment". For this reason Galsi undertakes to work in accordance with the law, and apply the best available technologies, to promote and plan its business development so as to valorise natural resources, preserve the environment for future generations, and promote initiatives for the broadest protection of the environment.

Since 2004 Galsi has worked alongside qualified research centres, engineering, geological and environmental companies and industry experts to analyse the environmental impact of the infrastructure and optimise the technical choices, minimise disturbance and identify the best ways to mitigate harm and restore the original environmental conditions. The findings were included in the Environmental Impact Study (EIS)(glossario) which Galsi presented to the authorities to demonstrate compliance with the strictest environmental protection standards. The Ministry for the Environment and Protection of Land and Seas and the Ministry for Arts and Culture will jointly engage in an "Environmental Impact Assessment" to certify compliance with prevailing environmental regulations and the eco-compatibilitytale of the project. A similar process will be carried out by the competent authorities in Algeria.

The Environmental Impact Study, based on Environment Ministry guidelines, examines the possible environmental impacts on the:

  • air
  • water, marine and coast environment;
  • soil and subsoil;
  • vegetation, flora, fauna and ecosystems;
  • countryside;
  • human ecosystems;
  • noise levels.

As the study makes clear the impact of the Galsi project on each of the environments in question will be minimal, only for the duration of the construction, work, and will be almost entirely reversible. Once in operation the pipeline will have no interaction with the surrounding environment since it will be buried and therefore invisible, and will have no impact on the local territory..

The compressor stations will produce very low emissions and noise and in any case well below the levels permitted by law. To keep emissions from the gas turbines in the compressor stations to a minimum, cutting edge technologies will be adopted incorporating low emissions high efficiency combustion systems. Great care will also be taken to screen the facility and ensure that it blends into the countryside without spoiling the natural landscape. In planning the project Galsi has been advised by top environmental engineering and architecture experts throughout.

The route and landing points for the pipeline were determined on the basis of atrade-off between the technical feasibility constraints and the need to limit interference with the environment. Both the onshore and offshore sections have been carefully planned to guarantee minimum disturbance to nature and protected areas. In stretches close to the shore and for the entire length of the onshore line the pipe will be buried to avoid affecting the surrounding ecosystems. Galsi performed extensive research and onsite inspections of the area, adopting the latest pipe laying technologies, including sophisticated “trenchless” techniques for the offshore sections to ensure minimum interference with the marine environment.

Once the construction and burial phases are complete, the original natural habitat will be fully restored. The measures to mitigate damage and restore the vegetation are designed to integrate the infrastructure as far as possible into the natural environment, both during construction through specific design choices, and subsequently with special engineering solutions to preserve the original conditions.

Restoration works will be approved by the competent authorities (Regional Authority, Forestry Corps). The seeding and tree planting process as well as the choice of species will be performed in conjunction with the National Forestry Corps and other competent bodies who will make joint inspections of the sites concerned. The final goal will be to restore the soil to its original condition and reinforce its stability.

The whole process who will be overseen by ateam of specialist engineers, geologists, forestry experts and agronomists who will assess the impact of the works on the environment and ensure maximum eco-compatibility.
