Calculation of Carbon Footprint Per Year


The Carbon footprint calculation can be conducted based on the stage of calculation as stated in www.carbonfootprint.com, which is the sum of electricity usage per year and transportation per year.
a. Electricity Usage Per Year 
The CO2 emission from electricity 
= (electricity usage/year in kWh/1000) x 0.84 
= (1633286 kWh/1000) x 0.84 
= 1371.96 metric tons 
Notes: 
Electricity usage per year= 1633286 kWh
0.84 is the coefficient to convert kWh to metric tons (source: www.carbonfootprint.com)
b. Transportation Per Year (Bus) 
= (Number of the shuttle bus in your university x total trips for shuttle bus service each day x approximate travel distance of a vehicle each day inside campus only (in kilometers) x 240/100) x 0.01 
= ((15 x 150 x 5 x 240)/100)) x 0.01 
= 270 metric tons 
Notes: 
240 is the number of working days per year 0.01 is the coefficient (source: www.carbonfootprint.com
) to calculate the emission in metric tons per 100 km for bus
c. Transportation Per Year (Car) 
= (Number of cars entering your university x 2 x approximate travel distance of a vehicle each day inside campus only (in kilometers) x 240/100) x 0.02 
= ((2000 x 2 x 5 x 240)/100)) x 0.02 
= 960 metric tons 
Notes: 
240 is the number of working days per year 0.02 is the coefficient (source: www.carbonfootprint.com
) to calculate the emission in metric tons per 100 km car

d. Transportation Per Year (Motorcycle) 
= (Number of motorcycle entering your university x 2 x approximate travel distance of a vehicle each day inside campus only (in kilometers) x 240/100) x 0.01
= ((4000 x 2 x 5 x 240)/100)) x 0.01 
= 960 metric tons 
Notes: 
240 is the number of working days per year 0.01 is the coefficient (source: www.carbonfootprint.com
) to calculate the emission in metric tons per 100 km for motorcycle

e. Total Emission Per Year 
= total emission from electricity usage + transportation (bus, car, motorcycle) 
= 1371.96 + (270 + 960 + 960) 
= 3561.96 metric tons
Note:
You can use your own method and put it in evidence (e.g. figure, link, etc.)
