Whether during the study stage or the site monitoring stage, our environment and sustainable development engineers and study managers define strategies, evaluate scenarios and projects and carry out analyses for sustainable development.

This expertise is supported by their ability to:

• Establish methodologies that integrate sustainable development stakes, such as the creation of eco-mobility grids, assistance with drafting action plans, assistance for negotiations and organisation of technical and working group meetings to provide project improvement possibilities,
• Draft functional tools and tools to assist with the acknowledgement of sustainable development, such as the eco-comparison, the CO2 simulator, the Sustainable Development Management Plan (PMDD) which defines the objectives and highlights the actions to which participants are committed or the Environmental and Sustainable Development Management System (SMEDD) which covers the design and production phases and operational-related concerns,
• Innovate and propose new technical and managerial solutions by carrying out the Bilan Carbone® (carbon footprint), creating specific carbon evaluation tools (train stations, technicentres, networks) or through life cycle analysis for material selection.

INEXIA's sustainable development expertise also covers soft and active mode travel: cycle paths, bike routes, soft travel development schemes, green lanes and tourist routes.

"We carried out a study to evaluate greenhouse gas emissions for activities related to the operation of the 1^st phase of the Rhine-Rhône HSL Eastern branch and the construction of two TGV stations. This was a real challenge as the study related to 30 years of operation after commissioning at the end of 2011". Aurélia Gravet, Sustainable Development Engineering Domain Manager.
