The age of carbon footprinting
What is carbon footprinting?
In its simplest form; energy x carbon co-efficient
For example, gasoline density is 2,791 grams per gallon, containing 85.5% carbon by weight. Therefore, one gallon contains 2,386 grams of carbon
When combusted, oxygen molecules combine with carbon, making carbon dioxide. C + O2 = CO2

The age of carbon footprinting
Carbon weight = 12Oxygen weight = 16Combined weight = 12 + 16 + 16 = 44
Ratio of C to CO2 = 12:44, CO2 weighs 3.67 more than C

The age of carbon footprinting
One gallon of gasoline = ~ 6lbsOne gallon of gasoline becomes ~ 19lbs of CO2
One gallon of gasoline becomes 172 cubic feet / 4.87 cubic meters of CO2
February 2008Green Infrastructure and Sustainable Communities17-14
The age of carbon footprinting
One metric tonne CO2 = 2,204 lbsOne gallon of gasoline = 19 lbs114 gallons of gasoline = 1 tonne CO2
1 tonne of CO2 easily fills up a 19,000 cubic feet / 556 cubic meter container

Recap
• Climate change will change parameters of all infrastructure and processes
• Everything can and will be expressed in carbon• A project’s carbon footprint will be an increasingly
important evaluation criteria
• Help establish your organization’s carbon footprint, extend that practice to client work
