STRATEGIC ISSUES

A collaborative process

To guarantee the reliability of the entire materiality

analysis process, Société du Grand Paris approached

specialist firm “Des Enjeux et des Hommes” to assist

it in implementing the process and in processing the

stakeholders’ responses.

The materiality matrix was developed using

a three-stage approach:

1. Identification of the main issues

Taking into account existing benchmarks and

guidelines, such as ISO 26000 certification or the

UN’s Sustainable Development Goals, a list of

CSR expectations related to the activities and

missions of Société du Grand Paris was drawn up.

This analysis was based on existing documentation

and Société du Grand Paris’s CSR roadmap formalised

in 2019.

2. Identification of stakeholders

The mapping of stakeholders, both internal and

external, was already available thanks to the detailed

knowledge acquired by Société du Grand Paris

as part of its process of ongoing dialogue

(the stakeholder wheel). This served as a basis

for the identification work specific to the materiality

exercise that enabled each stakeholder to be

approached. Some stakeholders were grouped

together to ensure that all categories and types of

stakeholders were represented in the analysis of the

results. Thirteen categories were defined.

3. Consultation with stakeholders

The consultation was carried out by way of an online

questionnaire, which was sent, between 17 November

and 7 December 2020, to 800 internal employees

and 2,200 contacts among the external stakeholders

identified. Local residents and users of the Grand

Paris Express were also involved in this consultation

through social media networks, in compliance

with the General Data Protection Regulation.

All stakeholders consulted were asked to assess

their level of expectation with regard to each issue

by ranking them on a scale of 1 (low expectation) to

4 (high expectation).

High level of participation

A total of 1,054 responses were received for this

survey, of which 754 were from external stakeholders.

This high level of participation and the wide range of

stakeholders represented meant that the results

could be consolidated to produce a materiality matrix.

The results confirm the consistency between the

expectations of external and internal stakeholders

and the guiding principles chosen by Société du

Grand Paris in both its 2019-2024 corporate strategy

and CSR approach.

Conclusion

Of the 18 issues listed in Société du Grand Paris’s

2020 materiality matrix, eight stand out as strategic

issues in the eyes of both external stakeholders and

internal employees (see matrix below). The analysis of

the risks linked to these eight strategic issues will be

used to define objectives for each one, build

appropriate action plans and measure their

performance regularly through key indicators.

Société du Grand Paris will integrate these aspects

into its CSR approach and share its progress with all

its stakeholders. This will enable it to review the

priorities of its CSR approach at regular intervals.
