Global Warming Impacts on the Business Directly: • Unstable raining cycles and droughts, more evaporation at dams, more consumption due to hot weather, more algi blooms, eventual spread of POPs/contaminants at watertables. Undirectly: • Investments / expenses for accomplishing to S. Paulo State challeging targets (20% reduction till 2025 – base line 2005); • Damage to installations (WTP in Franca and Campo Limpo were flooded in 2009).
Key Role of the Sanitation Sector • an electro intensive sector due to the needs in aeration at the wastewater treatment and for pumping water and sewage (more for water, that is distributed pressurized, than for sewage, that is mostly collected by gravity) – Sabesp is the major electricity consumer at São Paulo state, responsible for 1.82%; • the size at the economy: at Brazil, sanitation is responsible for 2.0% of the total GHG emissions at 2005 (2.0% at 1990). In absolute figures in 2005: 18107 Gg de CH4 e 639 Gg de CO2 . For comparison: gargage emissions mean 7.8% and industrial effluents 3.3%, (Source: Brazilian 2nd Nat. Com. to UNFCC – 2010). At the S. Paulo State Inventory the sanitation means 1.6% (26.5% of "Residues & Effluents" that means 6% of the GHGs issued at the state). The industrial effluents contribution is 1.1% and the industrial incinerators, 0.01%;
Positive inertia trend of the sanitation The sanitation potentially reduces emissions as universalization comes through, due to several reasons: 1) less methane generation at septic ditches and rivers beds (anaerobic degradation of settled solids from sewage discharges); 2) activated sludge treatment is the leading option for treatment. It is aerobic (generating mostly CO2) vs. anaerobic / facultative ponds (generating methane); 3) biogas from biodigesters to be burnt in general in flares or CHP plants abating methane. Obs: the inventories do not show this trend as compile emissions from existing plants.
Opportunities for conciliating “Ecology and Economy” • reducing water losses (leakages) and at the same time: 1) consu-ming less electricity (for pumping and treating); 2) avoiding investments for bringing raw water from even more far, with extra pumping costs; • promoting ciliary reforestation at rivers, lakes and dams and at the same time: 1) keeping the quality of the water natural resources, meaning less treating chemicals; 2) preventing erosion and so floods, flow reduction and poor quality by silting; • stimulating / inducing water rational use among consumers and at the same time: 1) creating a new service for the larger customers; 2) avoiding investments in developing new resources; • producing energy from dams and discharges level differences (hydropower with no new flooded areas); • burning WWT plants sludge and biogas and generating electricity and steam (heat for termophilic digestion meaning more methane and less sludge). Conclusions: Positive inertia on GHGs of the sanitation universalization, besides social & environmental benefits.
1st Inventory of a sanitation company in South America In 2008, Sabesp published its 1st Carbon Inventory pointing out 1.719.159 tonnes of CO2-e, ref. year 2007. The main source of direct emissions is the collection and treatment of sewage, corresponding to 93.2%. The 2nd most important are undirect emissions from electricity consumption: 3.7%. Note: the evaluation has followed the GHG Protocols.
CDP reporting since 2006 ... • Decision made for starting CDP Supply chain in 2011 (200 key companies will be selected (ABC curve) and involved); 2.6 billion without access to sanitation; • Perspective to adhere to the new “CDP Water” (survey on water footprint published at the Water Rational Use Handbook for Commerce Firms) in partnership with Fecomercio (Federation of Commerce in S. Paulo State).
Sabesp supported at COP15 more challenging goals Our CEO has subscribed the UN Global Pact “Seal the Deal Campaign” (148 messages from CEOs - 12 from Brazilian companies) Sabesp is the Brazilian leading sanitation company, proud to be in the Global Pact. The global warming will impact our business, affecting the rain cycle. So we are already taking actions for saving energy, reducing water losses, producing from renewables like biogas and hydropower at dams and sponsoring ciliary forest projects. Sabesp follows São Paulo State Policy on Climate Change, that express its commitment to overcome this challenge. We aim to do more and hope the world leaders agree a powerful compromise for dealing with this threat for the mankind and other species at Earth, our common home. Gesner Oliveira Sabesp CEO
Sabesp sponsors partnerships for awareness and projects on the GW issue An initiative for divulging sustainability concepts and good practices by a portfolio of 36 magazines and an exclusive site organized by Abril - the leading publishers group in South America. Promotion of meetings (Ex: Pavan Sukhdev – UNEP, Nobel prizes Al Gore and Muhammed Yunus; awareness exhibitions like "Planet at Ibirapuera Park" in São Paulo, manuals promoting citizens good environmental attitudes etc.). www.planetasustentavel.com.br Sponsoring partners
Through the partnership with Fapesp, Sabesp will take a major leap in research, technology and innovation… (R$ millions) • One of the 7 research lines is projects for energy efficience • FAPESP is one of the main institutions to develop scientific and technological research in Brazil. It has an annual budget of R$ 400 millions. FAPESP SABESP
Cooperation with leading tecnology companies… Sabesp and GE signed a technical cooperation agreement for partnerships in projects in water and sewage treatment (ultrafiltration membranes, MBR), effluent reuse and energy generation in Brazil and abroad.

1 Million Trees at Cantareira “The water doesn’drop from trees, but without trees, there is no water” A partnership with NGOs (Inst. Ipê and The Nature Conservancy) 552,000 saplings from 60 different species planted in 2009. The project is supported by local municpalities and the SP Environmental Affairs Secretary. It involves local people awareness and a restoring workers cooperative was created.

Fleet renewed with flex-fuel cars and optimization In 2009, 4,800 light and heavy vehicles from the service fleet were substituted by flex-fuel ones and alcohol feeding was made compulsory. The conversion brought 1.2 million liters savings per year, due to better performing engines and racionalization of the number of cars (1,605 owned vehicles decommissioned to 1,442 leased). The maintenance was streamlined with contract clauses related with performance. The share of alcohol at the total fuel purchased has increased from 17 to 28% (Obs: in Brazil the diesel contains 5% of biodiesel). The overall effect was an annual reduction of 1,200 t of CO2-e emissions.
