Respecting the environment: a primary concern

Mitigation and compensatory environmental measures

From the very outset, Oc’Via struck a balance between environmental concerns and technical constraints, introducing mitigation and compensatory measures in partnership with local environmental authorities to protect flora and fauna along the railway corridor. During the construction phase for example, artificial homes were created to protect certain species.


Creation of an environmental Monitoring Unit

Set up before the start of construction work and for a duration stretching up to five years after the commissioning of the line, this Monitoring Unit assesses the impact of the project on the environment and tracks the deployment and efficiency of the mitigation measures.
