3 1. Syndicat des Eaux d'ile de France : 4,4 millions inhabitants 3

4 1. SEDIF : a public water authority Decides upon corporate strategy (management model, territory, targets related to sustainable development, etc...) Sets tariff structure and service level continuity of service sustainable financing and budget allocation Owns and manage infrastructure : asset management, investment planning and implementation Capex : 125 M /yr 4

5 1. SEDIF : Day-to-day operation and management delegated to Veolia Eau d Ile de France New contract since years contract employees Production and distribution Water quality Customer service Monitoring and maintenance Incentives/penalties based upon performance targets Operations Customer service Sustainable development 5

6 1. Syndicat des Eaux d'ile de France SEDIF: - 20% CO 2 emissions by 2020, 100% of renewable energy by % energe;c consump;on by 2020 France: Divide CO 2 emission by 4 by 2050, - 20%: 2020, 23% of renewable energy by 2020 Europe Divide CO 2 emission by 4 by 2050, - 20%: 2020, 20% of renewable energy by 2020 World: Divide by 2 the CO 2 emissions by

14 3. Objectives Veolia Eau d Ile de France commitments CO 2 Reduce by 20% the CO 2 emissions Incen;ve if reduc;on higher than 33% Energy Reduce by 6% the consump;on of electricity /m 3 Buy 100% of Green electricity by 2013 install a heat pump in Méry- sur- Oise treatment plant Transport Electric Vehicles for at least 3% of the pool in 2014, 10% in 2017, 18% in

15 4. Figures and action plan First figures comparison 2011/2012 n Acids/bases consumption: -562 tco 2 Légende : tonnes Seine Marne Oise Acide sulfurique - 96% Acide ortophosphorique - 75% Soude - 30,5% Chaux Neutralac H - 92% Chaux vive Neutralac Q3-92% Acide citrique C6H8O7-50% 15

16 4. Figures and action plan The main drivers for energy-linked gains are: n Membrane renewal optimization n Ozonation steps optimization n Network efficiency (leaks management) n Pumping optimization 16

17 4. Figures and action plan Estimated effects of the contract s commitments : At least 20% off in 2020 tco 2 Energy Materials and services Freight Transporta;on Fixed assets and works In & out waters Green electricity and energy efficiency Distance reduc;on (km) and electric vehicules Decrease in renewal of meters Ref: Carbone 4 17

18 4. Figures and action plan More reduction with additional actions Change mineral GAC by coconut GAC Product mineral GAC generates 4 ;mes more CO 2 than coconut GAC Move from fuel to biomass Replace fuel boiler by biomass boiler Develop trenchless technology Trenchless technologies allow dividing by 4 the emissions of tradi;onal technologies Use recycled materials Recycling avoid the extrac;on and transporta;on of raw materials 18

19 4. Figures and action plan Target 33% off in 2022 could be reached with these additional actions: 2011 Commitments Energy Materials and services plus Freight consump;on Transporta;on reduc;on Fixed assets and works In & out waters GAC replacement (mineral by coconut) Biomass replaces fuel Trenchless works Ref: Carbone 4 19

20 4. Figures and action plan On line monitoring of energy and chemical consumption in SERVO 20

21 4. Figures and action plan Offsetting CO 2 emissions through reforestation: Planting of 500,000 trees per year in emerging countries Costa Rica, Ecuador, Peru, Colombia, Sénégal, Madagascar, India 26

22 5. Conclusion SEDIF targets are more ambitious than European objectives To achieve these objectives most of the commitments have been transferred to Veolia Eau d Ile de France: 1. Realized a first carbon footprint as a reference in the contract 2. Develops industrial monitoring tools to improve the knowledge of the service and the energy consumption (ServO) 3. Identified the main drivers and started the implementation for CO 2 emissions reductions to reach the zero carbon footprint : Reduction of emissions Improvement of energetic efficiency Compensation 27
