The two main challenges faced today are the fight against climate change and the protection of biodiversity
In order to develop new establishments Snam adopts procedures that meet stringent environmental compatibility and safety assessments.
With regard to developing the network of gas pipelines, which represents the most recurring and significant event, in the design phase the path is chosen from among different alternatives, seeking to avoid or reduce to the necessary minimum the network’s passage through developed areas or those in which new residential settlements are expected, areas of significant natural or cultural interest, archaeological areas and geologically unstable areas.
These assessments are made as part of the Environmental Impact Assessment (EIA), after which the administrations in charge, both centrally and locally, issue the authorisations provided for by current regulations.
On the website of the Ministry of Environment it is possible to find the ongoing investigations and the granted provisions about projects subjected to EIA, while on the website of the Ministry of Economic Development (available in italian only) it is possible to find procedures about gas pipelines and compressor stations for which the Construction Authorisation is granted.
Once obtained the expected authorisations, in order to restore the ecological value of the areas, Snam designs and implements environmental protection measures, with specific actions to restore the natural habitat.
Right from the design phase, Snam conducts field studies to understand the areas affected by the laying of pipelines. The various specialized surveys (geognostic, hydrological, forest, botanic, faunal, landscape, etc.) carried out analyse the main faunal, botanic and soil parameters of the areas, without any impact on vegetation, water or existing ecosystems.
This work is carried out by highly skilled personnel (including engineers, surveyors, geologists, agronomists, foresters and naturalists) who examine the entire area in order to identify the best routes.
The results of these studies help the company to make the most appropriate design choices to minimise the biodiversity impact, especially during the construction phases, which are followed by environmental restoration and monitoring, carried out in agreement and in cooperation with the entities in charge.
The purpose of the environmental monitoring projects is to verify the renaturalisation process along the stretches of pipeline laid, based on a comparison of the original environmental conditions (“ante operam”) and the environmental conditions once the works have been completed (“post operam”). In particular, monitoring is carried out on more significant habitats (directly and/or indirectly affected by gas pipelines in development) that are identified and analysed during the “ante operam characterization” phase of the project.
The objective of vegetation restoration, especially reforestation, is not merely to rebuild the forested areas, but also to reconstitute the countryside and restore the biological function of areas with specific biodiversity characteristics.
Restoration and reforestation are followed by the execution of “plant care”, i.e. caring for and maintaining the bedded-out plants for a period of at least five years.
The stages of biodiversity
Snam produced guidelines for the “conservation and sustainable use of biodiversity in the design, construction and decommissioning of pipelines” with a dual purpose:
- to provide guidelines for the best possible actions to ensure the respectful and sustainable use of biodiversity in its gas pipeline operations
- to provide an additional knowledge base for all company personnel
An operating unit within Snam Rete Gas was established to perform centralised activities for the conservation of biodiversity, ensuring the coordination and implementation of environmental impact assessments.
2012 - 2016
Published the Sustainable Pathways series; the series was created to raise awareness of Snam's commitment to safeguarding the environment, vegetation and morphological restoration. The second volume of the series was realized in 2013 and it reports on the collaboration between Parco delle Prealpi Giulie and Snam which led to the creation of the Malborghetto-Bordano pipeline. The third volume, dedicated to Maiella Park, was realized, while the fourth volume, dedicated to Ticino Park was published in 2016. During 2016 was also created Seasonal paths, an information and multimedia support created by Snam in conjunction with Federparchi and three Italian parks (Nebrodi, Prealpi Giulie, Ticino), the main protagonists of the project. The digital platform is composed of a website that houses the history of the region of the park and a mobile app so that you can always have your itinerary with you, even when there is no signal.
