There are four levels of core social indicators:
The complementary nature of these four levels of indicators makes it possible to measure the results of the Group’s human resources policy and social commitments.
Some of the workforce-related indicators published for 2022 do not include data from Cobra IS (newly consolidated in 2022). They are safety, absenteeism, remuneration and employer social contributions.
The core environmental indicators are made up of seven types:
These types of indicator were taken from the following sources:
Each business line continues to use its own additional indicators, which are based on its specific environmental challenges.
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 the worksites of VINCI Construction’s Building France, Civil Engineering France and Road France divisions, for the worksites of the Earthworks, Maritime and River Works delegation of VINCI Construction’s Networks France Division and for Soletanche Freyssinet in France. In France, average unit prices come from national framework agreements and the 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 50% 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.
Total energy consumption is expressed in megawatt hours (MWh) higher calorific value (HCV). The conversion factors used are 10.66 kWh/litre for diesel fuel, 9.82 kWh/litre for petrol, 11.15 kWh/litre for used oils, 11,833 kWh/tonne for heavy fuel oil and 3,069 kWh/tonne for coal (lignite). These factors were obtained from Ademe’s Bilan Carbone worksheet V8.6.
The conversion factors used to calculate greenhouse gas emissions are from the 2022 Ademe Base Carbone® database for Scope 1, and from the 2020 International Energy Agency (IEA) database (published in 2022) for Scope 2. The conversion factors were updated on 31 December 2022, resulting in a 4% reduction of VINCI’s Scope 1 emissions and a 9% reduction of Scope 2 emissions, using the market-based method.
In 2022, 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).
