Sanitation & Climate Change
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) consuming 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.
Sabesp carbon inventory
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 efforts for mitigation
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.

Reducing water losses
Losses reduction in percentage figures
Sabesp water loss: 26%. Circa the 1/3 comes
from non payed water and frauds, most of it at
slums in S. Paulo Metropolitan Region.
Brazil’s water losses: aprox. 40 % of the
WWT and wells output.

one of the largest in the world ...
EXPAND the use of water reuse in the
INDUSTRY
ENABLE the water supply needed to the

Supply capacity: 1.000 l/s
Enough to supply a city of 600K inhab.
Total investment: R$252 million
Renewing the vehicles fleet &
Ethanol use
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.

Think about GW in daily habits – reduce the gap
between speaking and attitude
Each 1 PET bottle 1 liter of mineral water
requires 200 ml of oil for being made. The flight
from Fidj to San Francisco of mineral water
means 0.85kg of fuel per bottle. The world
consumes 180 billion liters of mineral water per
year. This businesss issues 60K tonnes yearly
only in Australia = 13,000 cars.

(of course if it is from a good supplier)
