Phoenix College Carbon Emissions Report
Scope of Project
• To determine, track, and potentially reduce:1. Direct emissions from sources that are owned and/or
controlled by your institution (Natural gas, propane, gasoline, diesel fuel, refrigerants, fertilizers).
2. Indirect emissions from sources that are neither owned nor operated by your institution but whose products are directly linked to on-campus energy consumption (Purchased electricity).
3. Other emissions attributed to your institution, deemed “optional” emissions by corporate inventories (Employee/student commuting, district financed air travel, landfill waste, paper).
*Note: Emission sources that do not pertain to PC’s campus have been excluded.

Emissions per Operating Funds
Emissions per operating dollar estimates the environmental impact of PC operation.
The upward trend in 2009 is due to an
increase in employee/student commuting. These emissions are not considered to be under the control of the institution.
