1. Carbon Footprinting

2. By the end of the session you should be able to…
Understand what carbon footprinting is and why organisations and individuals do it
Understand how to start calculating your own carbon footprint

3. What is included?
Developed by Mike Berners-Lee for the WWF.

4. How do you carbon footprint something?
Fuel Type Measurement
Unit
Emissions Factor kgCO2 / per
measurement unit
Electricity
kWh
0.541
Natural Gas1
0.1836
In 2013/14 Joe Blogs used 4,750 kWh of electricity and 5,200 GWh of natural gas.
Electricity = 4750 x 0.541
= 2, kg CO2
Gas = 5200 x
= kg CO2
Total = 2,
= kg CO2

5. Try and calculate my footprint.
Electricity: kg CO2/kWh
= 1652 x 0.541
= kg CO2
Natural Gas: kg CO2/kWh
= 8445 x
= kg CO2
Total carbon footprint from energy consumption: =
= kg CO2
=2.44 t CO2

7. My annual footprint is c 7. 87t CO2/yr
My annual footprint is c 7.87t CO2/yr. Annual global comparison include (World Bank, 2009):
UK – tonnes
United States – tonnes
China – tonnes
India – tonnes
