Environmental audit of the school Lorenzo Da Ponte by the class 3E

1. ENVIRONMENTAL AUDIT OF OUR
SCHOOL LORENZO DA PONTE
ELECTRIC ENERGY
HEATING
TRANSPORT
PAPER
WATER
WASTE
Comenius project “Let’s know, let’s love, let’s protect
our environment”

2. OUR PROJECT
Investigate CO2 production related to our lifestyle, in order to
reduce CO2 emissions.

3. The 6 main aspects are:
Electricity
Water
Heating
Paper
Transport
Waste

4. The tasks
3^ A
Collecting data
Saving behaviours
3^ E
Finding out formulas
Excel Calculation

5. Class 3^ E

6. Our final product

7. ELECTRIC
ENERGY

8. When we use less electricity,
power plants produce less kWh
therefore, carbon dioxide
emissions are reduced
Electricity impacts on
Carbon Dioxide production

9. FORMULA
Kg of CO2 Kwh 0,72
1 kWh
= X
0,72 kg CO2

10. Water

11. How
does water consumption produce CO2?
Water is pumped
and brought to our
houses
After the use, water is
brought to the depuration
plants
At the end the depurated
water is restored to the
natural cycle.

Formula

14. Heating
in our school is due to methan
burning

15. C E
Methan 8250 kcal/m3 0,2338 gCO2/kcal
How
does heating produce CO2?
2- E = emission of CO2
1- C = amount of energy prduced by the fuel

17. PAPER

18. Paper production needs:
How
does paper consumption
produce CO2?

Chemical products Cut of trees

19. TYPE OF PAPER KGS OF CO2
PRODUCED
White paper 1,7
Recycled paper 0,75

20. Kgs of white paper

21. MEANS OF
TRANSPORT

22. Means of transport produce carbon
dioxide through fuel burning
HOW DO MEANS OF TRANSPORT
PRODUCE CO2?

23. EMISSIONS FROM SOME MEANS OF
TRANSPORT
F
Car 237 (gCO2/km)
Motorcycle 90 (gCO2/km)
Bus 75 (gCO2/passenger/km)
Train 45 (gCO2/passenger/km)
Tube 22 (gCO2/passenger/km)
Tram 33 (gCO2/passenger/km)
Plane 150 (gCO2/passenger/km)

27. Responsible for emissions from waste is especially
the methane that is released from biodegradable
garbage disposed in landfills. The fraction that is not
captured to produces energy, spreads into the
atmosphere.
