2013-vinci-annual-report

The water and energy consumption of Eurovia France, Belgium and Poland – and, since 2012, the worksites (“mobile sites”) of VINCI
Construction France (previously estimated using a statistical method) – are calculated based on expenses and average unit prices for the
reference period. Continued efforts are being made at Eurovia to report energy consumption directly.
For VINCI plc, figures for total waste generation and the percentage of waste recycled are based on estimated fill ratios of waste skips, taking
into account the type and density of the waste.
Reporting of water consumption currently covers all water purchased. Water withdrawn directly from the environment is recorded by some
entities but is not yet included in consolidated reporting. VINCI is continuing its efforts to expand and improve the reliability of this reporting
item over a broader scope.
184 VINCI 2013 ANNUAL REPORT
Since 2011, VINCI Park in France has altered its method of calculating purchased water consumption. For car parks outside Paris that do not
have automatic sprinkler-type fire extinguishing systems, water consumption is calculated from the total purchase cost of water divided by
its average price in France. For other car parks, water consumption corresponds to the volume of water purchased.
Total energy consumption is expressed in MWh Higher Calorific Value (HCV). The conversion factors used are 0.0104 MWh/litre, 12.027 MWh/
tonne and 4.839 MWh/tonne for motor fuel, heavy fuel oil and coal (lignite), respectively.
The figures in the Annual Report 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 2012
annual report were adjusted in 2013.
Occupational illnesses are defined as illnesses contracted following prolonged exposure to a professional risk (noise, hazardous products,
posture, etc.) and recognised as such by the regulations in force, where such regulations exist. In most cases, the number of days of absenteeism
for occupational illness includes days lost due to illnesses declared as occupational but not yet formally recognised as such. The
Group continues to educate subsidiaries about the need to harmonise reporting practices.
4.5 Consolidation and internal control
Social data is collected from each operational entity using a specific package of the “Vision III” data reporting system, including automatic
controls. Data is checked and validated by the Group entities themselves.
This data is then consolidated in two steps:
ˇˇ
Step 1: each business line consolidates all data within its scope. When consolidation takes place, data consistency checks are carried
out. Having been consolidated and checked at the business-line level, data is then provided to the Group Human Resources department;
ˇˇ
Step 2: the Group HR Department consolidates data across the whole scope and checks its consistency.
Environmental data is collected, checked, consolidated and validated by the environment managers in each business line and division using
their own IT tools. The data is then consolidated centrally using “Vision III”. When consolidation takes place, data consistency checks are
carried out at Group level by the Delegation for Sustainable Development. Comparisons are made with the previous year’s data and any
material discrepancies are analysed in detail.
4.6 External controls
Each year since 2003, VINCI has asked its Statutory Auditors to give their opinion on the quality of the procedures used to report social and
environmental information. In 2013, both Statutory Auditors were appointed as independent third-party bodies in charge of verifying the
information published in the “Social and environmental information” chapter. The nature of the auditing work carried out and the findings
are presented on pages 192 to 194.
