La protection du loup

An eco-sustainable project

The base tunnel between Italy and France originated as part of a project to protect the environment of the delicate Alpine region. It is one of the cornerstones of the TEN-T network, which has the goal of connecting national and European infrastructure networks, but above all a priority operation within the framework of the decarbonisation goals foreseen by the Green Deal, the new €1 trillion EU investment plan.
TELT’s Environmental Policy
TELT’s policy is based on the idea that, as a work of European priority, the development of the Lyon -Turin- base tunnel be realised in line with the safeguarding of resources and promotion of the opportunities generated. Innovation takes a key place in this policy, which follows the sustainability guidelines included in the 2030 Agenda for Sustainable Development Goals.
Guidelines Governing the Construction Sites Project

In the case of a company such as TELT, which is building a project spanning more than one EU Member State, all elements concerning the environment are under the jurisdiction of the laws and regulations of the country in which the actual work takes place.

However, TELT has also implemented high-level comprehensive monitoring tools that cover both countries. These tools were the applied result of TELT’s environmental policy and allowed the company to gain the ISO 14001:2015 international certification for environmental management systems. This certifies the presence of a systematic and pre-established approach to the environmental management of the construction sites, with a special focus on the relationship with the locals as well as the authorities. TELT has always paid the closest attention to its local footprint and, since the beginning of its first surveys, it has adopted specific precautions (such as deploying numerous monitoring stations in France and Italy to keep under observation a vast area of water resources) and extraordinary control measures of the main environmental parameters. These actions are those that allowed the constitution of a large repository of lessons learned.

Noise and dust

The TELT construction sites operate in such a way as to minimize noise and dust emissions. The methods used are an improvement and refinement of those developed in recent decades in other large construction sites around the world, such as those of the Swiss base tunnels and of the Brenner.

The value of water

The project foresees that all the water collected within the tunnels, once it is divided by type of use (drinking water, hot water, etc.), will be made available to general use through a series of collectors that will convey it to the entrance.

Land use

In France as in Italy, over 50% of the surface area affected by the construction sites is not properly classifiable as natural environment but it is rather land that has already been exploited or that includes abandoned buildings. This confirms the importance of the ecological dimension in choosing and defining the work sites.

Environmental Controls

TELT’s commitment in all its sites can be summarised in the “Safeguarding the territory” programme. This one refers to the environment both as a natural habitat as well as to the historical and cultural system of local communities.

In Italy, the tools employed are the “localisation” of the project and a state-of-the-art system of environmental controls based on good practices already adopted during the excavation of the Chiomonte exploratory tunnel. In that case, TELT constantly monitored over 135 different parameters, including subsoil, hydrogeological risk, surface and subterranean waters, air, vibrations, noise, and electromagnetic fields.

Assessing the Impact on Citizens' Health

Following its successful trial in Chiomonte, the HIA – Health Impact Assessment – carried out by the Occupational Medicine section of the University of Turin will be applied to all construction sites.

The HIA, first applied to the Chiomonte exploratory tunnel, is a study that measures the possible effect of a construction project on the health of the citizens. The 80,000 samples collected from 40 stations during the four years of work did not identify any health hazard.

The study, drawn up by the University of Turin, has shown that the pre-existing environmental levels of Chiomonte have remained the same and that there has been no negative impact on the health of the citizens who live near the construction site.
