ENVIRONMENTAL & SOCIAL PERFORMANCE

METHODOLOGY Group reporting for the 2016 financial year is based on the guidelines set out in the Global Reporting Initiative (version 4). The Saur reporting protocol, established by the corporate social responsibility (CSR) department, specifically defines each indicator and the internal consolidation systems and resources used to produce Group-level data. These data are verified and validated at source, and are then tested for consistency during the consolidation stages by the originating departments and the CSR department. REPORTING SCOPE Quantitative reporting for France covers all the business activities of Saur and those subsidiary companies (excluding real estate and financial subsidiaries) in which the Group holded a 50% or greater equity stake on 31 December 2016. Internationally, it includes the main operating locations of Poland, Saudi Arabia, Spain and the UK, and adopts the same principles of the majority shareholder. This scope represents more than 95% of group employees. Sub-contracted services are not included. For some indicators, the values for particular entities may not be significant, and are therefore not incorporated. Similarly, indicators specific to certain areas of business activity refer only to more tightlycircumscribed scopes of reporting. In either case, the limitations of scope are indicated below. HISTORICAL INDICATORS Historical indicators are shown for two preceding years. Variances of reporting scope as a result of company disposal, company formation, company cessation or contracts won or lost are reflected in the indicators. SOCIAL INDICATORS The consolidated data are prepared on the same basis of calculation as those used for social reporting in France. In terms of management contracts, only Group employees are included in the scope. Workforce The figures shown refer to the number of employees present on 31 December of the financial year. They include civil servants on secondment, seasonal workers and expatriates. Employee turnover All recruitments made outside the scope of the Group are treated as external recruitments. Remuneration Salaries paid in foreign currencies are converted to Euros at the exchange rate prevailing on 31 December of the financial year concerned. Organisational structure, working hours and absenteeism The number of overtime hours shown corresponds to that shown in pay calculation and processing files. The rate of absenteeism shown represents the number of working days absence (accidents in the workplace and when travelling, illness, maternity leave, absences for family events, authorised and unauthorised unpaid absence, strike, layoffs and parttime working on health grounds) divided by the total number of working days. Training Only training provision covered by invoices (internal or external) is included. Total expenditure on training includes the salary costs of employees trained, transport and accommodation costs, and the cost of instruction. Safety The frequency and severity rates are calculated in accordance with the provisions set out in the French government order of 12 December 1985. Employee representatives Employee representative numbers are based on lists of elected or appointed representatives, and lists provided by trade union departments. They include the members and alternate members of the various entity employee representative organisations: union representatives, employee representatives, members of works councils and the central works committee, and unified employee representative bodies. 2016 Saur non-financial performance 2

ENVIRONNEMENTAUX ENVIRONMENTAL INDICATORS Water Water consumption relates essentially to the production of drinking water by Saur. The published value refers to the quantity of raw water abstracted from the natural environment to produce drinking water and/or water for irrigation. Drinking water The supply system efficiency, linear loss index and compliance rates are estimated in accordance with definitions P104.3, P106.3, P101.1 and P102.1 of the regulatory indicators for mayors. These definitions are published on the www.services.eaufrance.fr website. Wastewater treatment The figure for volumes treated is consolidated for all wastewater treatment plants with a capacity of 2,000 residents or higher, beyond which threshold the obligation for continuous flow monitoring and regular discharge controls applies. For these plants, the purification efficiency figures reflect the ratio between the quantities of pollution eliminated and those received by the wastewater treatment plant. They are estimated by analysing chemical oxygen demand and biological oxygen demand (COD and BOD). Waste Business waste Wastewater treatment sludge is the principal source of waste. For purposes of comparison, the quantity is expressed as dry material, independent of water content. The following are considered as waste recovery channels: composting, agricultural spreading, heat recovery and landfill generating and recovering biogas. Waste management by the waste management subsidiary The input quantities - weighed on-site at the point of acceptance - are generated by the invoicing management software. The figure shown for the proportion of waste recovered represents the new raw materials sold by Coved. Waste recovered by Coved, but invoiced by local authorities, is not included. As a result, the recovery rate is underestimated. Energy For management contracts, only energy consumed by Group employees is included in the scope. Primary energy consumption includes the fuel (diesel and vehicle natural gas) consumed by vehicles and machinery, and the natural gas and fuel oil consumed by buildings and processes. Electricity consumption includes buildings, technical facilities and office systems. The ratios per m 3 produced and kg COD (chemical oxygen demand) eliminated are calculated by isolating operationsrelated consumption and are used to monitor the energy efficiency of drinking water production and wastewater treatment processes. These items refer to the highest instances of electricity consumption. Consumption of green electricity generated from renewable energy sources is consolidated on the basis of certificates provided by suppliers. Renewable energy generation from biogas includes electricity sold and heat used on-site by waste storage centres. Air The figure given for total greenhouse gas (GHG) emissions refers to Scope 1 and Scope 2 emissions, as defined in the GHG protocol. Direct (Scope 1) emissions include CO 2, CH 4 and N 2 O, released as a result of: Fuel and natural gas combustion (emissions calculated using the Bilan Carbone spreadsheet). The decomposition of waste in waste storage (landfill) facilities, as declared in the legally-required annual declaration of emissions and transfers of pollutants and waste (Gerep). Wastewater treatment (emissions calculated in accordance with ASTEE - Scientific and Technical Association for Water and the Environment - standards, and validated by ADEME, the French Environment and Energy Management Agency). Indirect (Scope 2) emissions from consumption of purchased electricity are quantified using the Bilan Carbone spreadsheet and breaking down consumption by generating country. Emissions avoided are estimated on the basis of the quantities of new raw materials recovered and energy generated from biogas, subject to the associated emission factors. These factors are taken either from the Bilan Carbone spreadsheet or the EpE (Entreprises pour l Environnement) guide to emissions from waste management. 2016 Saur non-financial performance 3
