Contribution to climate change
The risk is that the target contribution to reducing greenhouse gas emissions resulting from the opening of the Grand Paris Express will not be achieved, which may take the form of:
– an unchecked increase in direct emissions due to more carbon-intensive construction methods; – or an overestimation of indirect emissions avoided due to unrealistic assumptions about modal shift or land-use planning.

– Sobriety in the design of structures and rolling stock – Use of low-carbon concrete and fibre-reinforced concrete in tunnels – Resource conservation in the construction of stations: efficient use of space, sober architecture, material savings, use of low-carbon materials, durability of materials, etc. – Exceed the targets of the 2020 environmental regulations for real estate projects – HQE-certified operations centres

e 8 Climate change adaptation Climate change adaptation relates to the company’s ability to take into account the impacts of climate change on the end product (the rail network and stations), paying particular attention to the presence of flood zones and the increase in violent weather events.

Vulnerability and exposure to climate risks
The physical risk relates to the increased exposure of Société du Grand Paris’s activities and the Grand Paris Express infrastructure to changes in the frequency and intensity of climatic events, particularly the most violent ones (heat waves, droughts, floods, etc.). These events may jeopardise the longevity of the infrastructure (deformation of rails or catenary, failure of electrical equipment, changes in crew and maintenance schedules, etc.), the service (changes in passenger habits, etc.) and passenger safety. It must take into account the sizing and coordination of the measures implemented to prevent or deal with these exceptional events.

Response to legislation and flood control measures – Development of Société du Grand Paris’s flood management strategy, which sets out the guidelines to be reviewed and integrated into the design of the Grand Paris Express infrastructure affected by the risk of flooding – Level of protection afforded to structures suited to the type of flood and implementation of additional protection on a case-by-case basis – Hydraulic compensation: volumes taken by the project from the flood expansion field will be compensated for, cubic metre for cubic metre – Strengthening of legal documents
Design of operating systems – Definition of suitable transport systems by operational teams – Preparation with partners for operation by future transport operators
Strengthening resilience – Mapping of physical climate risks within the scope of Société du Grand Paris’s activities
