Reporting cycle

The Sustainability Report is published annually on the instruction of the Board of Directors of Salini Impregilo S.p.A..

Adherence to best practice standards

The Salini Impregilo 2014 Sustainability Report has been prepared in accordance with the “Comprehensive” option of the new “GRI G4 Sustainability Reporting Guidelines” and with the “Construction and Real Estate Sector Disclosures”, issued by Global Reporting Initiative (GRI) in 2013 and early 2014 respectively. By applying the Comprehensive option, we chose to disclose all indicators related to the identified material aspects.

In addition, the Report contains references to the ten principles of the Global Compact, showing the actions and systems implemented by the Group in order to integrate these principles into the corporate strategy and day-to-day activities of the Company.

Material topics

In order to implement the Reporting Principles for Defining Report Content provided for by GRI G4 Guidelines, the Group has defined an internal procedure aimed at identifying, prioritising, validating, and reviewing material topics, as described here. Material topics identified through this process with related boundaries are listed below5. A complete list of significant sites where topics are material is available hereinafter.


 5. Topics regarded as not material are: Products and Services, Customer Health and Safety, Product and Service Labelling, Marketing Communications and Customer Privacy.

Third-party assurance

To guarantee the veracity of the information provided in the Report, and to improve the accounting procedures, Reconta Ernst & Young S.p.A. has been engaged to carry out audit activities. The independent assurance report is available here.

Scope of the Report

The 2014 Sustainability Report contains an overview of the initiatives and activities carried out by the Group in 2014, as well as performance data from the period 2012–20146 and significant events which have involved Salini Impregilo after the 2014 year end.

The information provided in the Report refers to Salini Impregilo S.p.A. and the consolidated companies.

Unless otherwise specified in the Report and/or in the GRI Content Index, the scope of the report follows the criteria described below:

  • Financial data relates to the scope of the 2014 Salini Impregilo S.p.A. Consolidated Financial Statements, except for the figures on local purchases;
  • Corporate governance data and information relates to Salini Impregilo S.p.A.;
  • Environmental and social data (plus local purchases) refers to a scope established applying the control approach to the backlog at 30 September 2014. Specifically, sites included in the report (listed below) are all the active projects with one of the following characteristics:
    • direct contract;
    • contract managed by a consortium/JV/temporary partnership in which Salini Impregilo is the leading partner.

The sites excluded from the scope are considered not relevant to the present document.

Comparative data (2012 and 2013) has been restated in respect to those published in the Sustainability Report 2013, in order to apply the control approach instead of the equity share approach used in the previous report.

Any specific limitations to the scope are directly indicated in the Report, particularly in the GRI Content Index.

It should also be noted that the injury figures in this report refer to a scope wider than the one used for the Group Quality, Environment, Health and Safety management system, which applies to contract where decision-making roles (e.g. Head of QSE) are entrusted to Salini Impregilo.

Below is a list of operating sites included under the reporting scope of the Sustainability Report. For more information about the projects, visit our website

  6. New performance indicators provided for by the GRI-G4 Guidelines are reported only for 2013 and 2014.

Calculation methods

Data and information included in the Report are taken from the information systems used for the general management and accounting of the Group’s operations, along with data from a specific sustainability reporting system established in accordance with the GRI requirements. Some data and information is drawn from public sources.

Reported data is calculated with due accuracy and, where specified, by means of estimates. The methodologies applied to determine the main indicators are shown below.

Safety indicators
Safety indicators are calculated in accordance with the “ILO Code of Practice on Recording and Notification of Occupational Accidents and Diseases” provided in the GRI Guidelines.

Rates reported are expressed as the number of injuries occurred (IR) and the related lost days (LDR) for each 100 employees.

In particular, the IR is calculated as a rate between the total number of injuries with prognosis longer than 3 days occurred in the period (fatalities included) and the total hours worked, multiplied by 200,000. LDR is calculated as a rate between the total number of lost days (related to injuries with prognosis longer than 3 days) and total hours worked, then multiplied by 200,000. Lost days are calculated taking into account the calendar days.  

Both IR and LDR are related to the total workforce, comprising both direct and subcontractors’ employees.

Although injuries incurred while commuting are not included in the calculation of the safety indicators, any accidents occurring to independent contractors (e.g. consultants) are included in employee injury rates. Injuries occurring at the Company headquarters and at other offices are not considered as material, as they do not relate to construction activities. For this reason these injuries, if occurred, are not included in the safety indicators.  

HSE expenses
Health, Safety and the Environment expenses reported refer to:

  • Health and Safety protection expenses including personal protective equipment, safety installations (e.g. fire-fighting equipment, grounding), emergency response equipment and services (e.g. rescue team, rescue equipment, ambulances, first aid, etc.), H&S monitoring activities (e.g. laboratories, instruments, measurements, etc.) and healthcare expenses (e.g. running of clinics, medical staff, medicines);
  • Environmental protection expenses including environmental plants (e.g. wastewater treatment plants), environmental emergency equipment (e.g. spills kit, absorbent materials, anti-spillover systems, etc.) and services (e.g. those provided by third parties through framework agreements), waste management, environmental restoration and remediation, monitoring activities (e.g. laboratories, instruments, measurements, etc.);
  • H&S and Environmental management costs including internal personnel dedicated to running HSE management systems, external consultancy and training costs.

Energy used
Calculations on internal and external (i.e. sub-contractors’) consumption of direct energy are based on conversion factors provided by the Intergovernmental Panel on Climate Change (2006 IPCC Guidelines for National Greenhouse Gas Inventories).

Water withdrawal, discharge, and reuse
Water not withdrawn from aqueducts, bought from other sources (i.e. via tanks), or measured by counter (included those discharged and reused), is estimated on the working hours of the draining pumps used and the capacity of these pumps.

Wastewater is estimated as a percentage of total water withdrawn, depending on the specific use of the water (production or domestic).

Rainwater, although collected and stored, is not reported because it is not considered material. The Group does not use wastewater from other organisations.

Greenhouse gas emissions
Calculation of the Group’s greenhouse gas emissions is based on:

  • The emission factors provided by the Intergovernmental Panel on Climate Change (2006 IPCC Guidelines for National Greenhouse Gas Inventories) for the consumption of direct energy;
  • The emission factors provided by the International Energy Agency (CO2 Emissions from Fuel Combustion, 2012 edition, 2010 data) for the consumption of indirect energy;
  • The emission factors provided by IPCC (Fourth Assessment Report AR4 100yr) to convert CH4 and N2O in CO2 equivalent;
  • The emission factors provided by the UK Department for Environment, Food and Rural Affairs (2011 Guidelines to Defra/DECC's GHG Conversion Factors for Company Reporting) for the shipment of goods.

Data on waste production are gathered in accordance with the Construction Waste Measurement Protocol issued by ENCORD (European Network of Construction Companies for Research and Development) in May 2013.

For operations within the EU, disposal methods have been determined according to the classification provided by law of each waste category. For those outside the EU, methods have been determined according to the specific contracts stipulated with external waste contractors.
