The sustainability information provided in this report was drawn up for the first year of application of the legal and regulatory requirements resulting from the transposition into French law of the European Union’s Corporate Sustainability Reporting Directive (CSRD). This first year of CSRD implementation raises several issues:
In light of these issues, the Group has focused on meeting the applicable requirements set by the ESRS at the date of preparation of this Sustainability report, based on available information.
Minimum disclosure requirements
The Group is actively continuing its work to meet the minimum disclosure requirements (MDRs). Targets and time horizons have been defined for certain key actions and specific activities. However, due to the diversity of the Group’s businesses and its decentralised organisation, not all information required on policies, actions, metrics and targets can systematically be reported at a consolidated level. This decentralised approach reflects the Group’s commitment to maintaining a flexible and agile strategy that can be adapted to the actual operating conditions of its business lines.
Explanations relating to certain social and environmental indicators
The methodologies used for some social and environmental indicators may be subject to limitations due to:
To measure the progress made by the Group in reducing its direct greenhouse gas emissions between 2018 and 2030, the reduction achieved in year Y is compared against an initial emissions baseline. Each year, the 2018 baseline is adjusted for emissions relating to acquisitions and disposals of companies during the period (see paragraph 5.2, “Changes in scope”, of the methodology note, page 274). Accordingly, emissions reported in 2018 are adjusted for changes in scope between 2018 and year Y, in order to track the Group’s progress against its emissions reduction targets on a like-for-like basis (see paragraph 5.3.3.2, “Progress against emissions reduction targets”, of the methodology note, page 274).
Uncertainties and limitations relating to certain environmental indicators
The Group has identified key areas for reducing direct emissions (Scopes 1 and 2) and indirect emissions (Scope 3). In these areas, its own initiatives combine with those of external stakeholders involved in the decarbonisation of its value chain. VINCI strives to accelerate these external efforts and strengthen its role as a driver of the low-carbon transition. Scope 3 emissions reduction will remain largely dependent on external factors, such as the electrification of mobility infrastructure and the decarbonisation of building materials and energy equipment (see paragraph 2.2.2.1, “Transition plan”, page 205).
Use of estimates
Due to the fast close process, some entities estimated their environmental data for the last one, two or three months of 2024. On its intranet, the Group provides a guide presenting six methods for estimating data for the final months of the year. Each entity can then select the method most relevant to its context.
For some entities for which environmental data was not available, the Group may have extrapolated data to cover its full scope, provided they contribute less than 5% of their division’s total revenue.
Some environmental indicators include estimated value chain data derived from indirect sources. This data refers to information from third parties or from estimates based on models, sector averages or data provided by value chain partners. For example, the Group uses estimates to calculate indirect greenhouse gas emissions (Scope 3) (i) to estimate activity data or to apply monetary ratios and (ii) to estimate emission factors when this data is not available. Overall, 52% of Scope 3 emissions were based on physical activity data. The overall uncertainty of the resulting Scope 3 data is estimated to be between 20% and 30% (see paragraph 5.3.3.3, “Scope 3 greenhouse gas emissions”, of the methodology note, page 274). VINCI is focused on improving the reliability of reporting to reduce the use of data estimates based on indirect sources.
In accordance with the EU Taxonomy, several estimates were needed, which are detailed in paragraph 5.3.4.2, “Methodological approaches”, of the methodology note, page 276.
