Environmental commitment
Alongside the infrastructure they build, AGIFI members are also responsible for managing environmental projects on a sometimes-impressive scale. These environmental aspects are a key part of the project agreements.
To limit the environmental impact of their projects and meet natural habitat preservation targets, AGIFI members rigorously apply the “avoid, reduce, offset” (ARO) principle. To do so, they develop close collaborations and partnerships with local stakeholders (environmental organisations, institutional partners) and experts in the field.
Beyond protecting biodiversity, AGIFI members have launched a number of initiatives to decrease their carbon footprint, reduce water and energy consumption, and improve waste management.
Some examples of environmental measures
AGIFI members have rigorously applied the “avoid, reduce, offset” approach to reduce the environmental impact of their projects.
Avoid
During the design phase, emphasis is placed on limiting the project’s environmental impact.
- Modification of routes to avoid the main sensitive/protected areas
- Protection of natural habitats (sites of high ecological value, limiting the destruction of wooded areas, keeping right-of-way requirements to a strict minimum)
Reduce
Creation of systems to monitor and ensure the long-term efficacy of these measures.
- Construction of structures to ensure ecological transparency, fish rescue and removal
- Restoration/creation of permanent or temporary channel diversions
- Installation of acoustic protection
Offset
The use of offset measures requires in-depth knowledge of the species, their lifestyles, and their ability to adapt and cohabitate. As a result, concession holders have developed very specific in-house expertise.
- Planting of hedges, bushes, and trees
- Installation of benches or floating pontoons to benefit certain species
- Construction of substitution pools
Carbon Footprint
As railway infrastructure managers, AGIFI members support low carbon mobility solutions and contribute directly to the reduction of greenhouse gas emissions.
The Public-Private Partnership model leads to comprehensive and long-term optimisation of all aspects of the project.
This provides a direct and immediate reduction in the quantity of “materials used”, with a positive impact on the project’s carbon footprint.
Examples of initiatives:
Reusing excavated material
Reducing the carbon footprint after construction
LISEA estimates the project will become carbon neutral before 2030.
The SEA HSL avoided more than 109,000 tonnes of CO2 emissions in 2019 thanks to the modal shift from road and air transport to rail. This corresponds to the annual carbon footprint of more than 9,900 French people. Thanks to the CO2 emissions avoided each year, LISEA estimates that the project will become carbon neutral before 2030, after offsetting CO2 emissions generated during construction of the line.

Environmental Observatories
These unique structures monitor public land-use planning investments to provide public scientific data about biodiversity protection to inform future projects.
The SEA, BPL, and CNM have created environmental Observatories on their lines.
These Observatories have several objectives:
These Observatories have several objectives:
- Evaluate the broad-ranging environmental impact of HSLs over time and verify the effectiveness of measures taken
- Improve knowledge and share lessons learned for future large-scale transportation and land-use planning projects.
Certifications
Project companies are spearheading a variety of initiatives to improve their waste, water, and energy management. As part of this effort, AGIFI members have sought out certifications.
In 2018, OPERE obtained ISO 9001 (Quality Management System) and ISO 14001 (Environmental Management System) certification for the Bretagne-Pays de la Loire line and the maintenance base. Oc’via and MESEA (the company that maintains the SEA HSL) are also working to obtain these certifications very soon.
