THE PRODUCT OF DIALOGUE
WITH STAKEHOLDERS
In 2020, Société du Grand Paris conducted a specific
consultation with its stakeholders to assess their
expectations and conduct its first materiality analysis.
This consultation enabled it to better identify its
“material” strategic issues, in other words, those
at the heart of stakeholders’ concerns in relation to
the main challenges facing Société du Grand Paris.
This analysis is presented in the form of a matrix that
maps both the issues related to the construction
of the Grand Paris Express and those specific to
Société du Grand Paris as a company. This matrix
ranks the expectations of both external and internal
stakeholders according to priorities that they
expressed.
