The methodologies used for some workforce-related and environmental indicators may be subject to limitations due to:
Data from subcontractors is included in the environmental reporting when VINCI is directly responsible for the data (i.e. the services or resources are provided by VINCI). In the event that VINCI companies operate as subcontractors, as may be the case for VINCI Energies, and do not have access to the data or their consumption is not material, then their water and electricity consumption data is not included.
The methodological guide to VINCI’s environmental reporting system allows for environmental data to be calculated based on spending and average unit prices for the base period, if source data is not available. This method is used in particular for VINCI Construction France worksites, VINCI Construction Terrassement worksites, Soletanche Freyssinet worksites in France and for Eurovia. In France, average unit prices come from national framework agreements and Eaufrance internet portal, which is a public information service on water and aquatic environments (for water consumption). At VINCI Immobilier, nearly 98% of the volume of waste is estimated. For its offices and agencies, estimates are based on actual data and cover about 75% of buildings. For its serviced residences, for which a waste per capita ratio is applied, estimates cover all the residences.
The figures in this Universal Registration Document are based on data known at the end of the financial year. They may, however, be adjusted the following year if a significant anomaly is observed and provided that the adjustment is substantiated in detail. None of the figures published in the 2020 Universal Registration Document were adjusted in 2021.
Total energy consumption is expressed in megawatt hours (MWh) higher calorific value (HCV). The conversion factors used are 10.66 kWh/l for diesel fuel, 9.82 kWh/l for petrol, 11.15 kWh/l for used oils, 11,833 kWh/t for heavy fuel oil and 3,069 kWh/t for coal (lignite). These factors were obtained from the French energy and environment non-profit ATEE (https://atee.fr/document calculette-de- conversion-des-unites-energetiques).
The conversion factors used to calculate greenhouse gas emissions are from the 2016 Ademe Base Carbone® database for Scope 1, and from the 2018 International Energy Agency (IEA) database for Scope 2.
In 2021, the location-based and market-based methods were used to calculate the greenhouse gas emissions produced by the consumption of electricity by Group entities (Scope 2). The location-based method takes into account the average electricity mix of the grid for each country where the electricity is consumed, applying an emission factor of zero to renewable energy use from self-consumption and under power purchase agreements. The market-based method calculates the emissions from the electricity actually purchased, applying an emission factor of zero for the consumption of electricity from renewable sources (including guaranteed sources).
To measure the Group’s performance in achieving its commitment to reduce greenhouse gas emissions from 2018 to 2030, an initial trajectory is being used as a baseline. Each business line has its own initial emissions reduction trajectory for 2030, based on the environmental commitments it has made and the intensity of its carbon reduction initiatives. Each year, the progress made is measured and the percentage by which actual emissions must still be reduced by 2030 is recalculated. This figure is based on two quantities (based on energy consumption data from the Group’s environmental reporting), which are actual direct greenhouse gas emissions for the past year, and actual emissions from changes in scope (acquisitions and disposals in the reporting scope) for the past year.
The progress made is measured for each business line, by applying the percentage of emissions remaining to be reduced by the business line to the cumulative emissions attributable to changes in scope for the past year (the sum of emissions from acquisitions, less the sum of emissions from the business line’s disposals). For example, consider an acquisition in year Y, included in environmental reporting in year Y+1. The emissions trajectory of this acquisition to 2030 is calculated by applying the percentage of emissions remaining to be reduced from the acquiring business line to the emissions of this acquisition in year Y+1. The acquisition is therefore included in the same trajectory as the acquiring business line.
The achievements of each business line are then consolidated to determine the progress along the trajectory made by the Group as a whole. Progress towards the Group’s target is thus measured each year by comparing the initial baseline with the performance achieved.
