Does the institution's GHG emissions inventory include all Scope 1 and Scope 2 GHG emissions?:
Does the institution's GHG emissions inventory include all Scope 3 GHG emissions from any of the following categories?:
| Yes or No | |
| Business travel | No |
| Commuting | No |
| Purchased goods and services | No |
| Capital goods | No |
| Fuel- and energy-related activities not included in Scope 1 or Scope 2 | No |
| Waste generated in operations | No |
Does the institution's GHG emissions inventory include Scope 3 emissions from other categories?:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
NAU uses Clean Air - Cool Planet: Campus Carbon Calculator
Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
A brief description of the internal and/or external verification process:
The Office of Sustainability is responsible for the GHG reporting and the Green NAU Energy Initiative verified the numbers below.
In 2013 a graduate class, "The Science and Management of GHG" conducted a parallel inventory of NAU's GHG to compare to internal assessment. The results coincided.
The Sustainability Director has taken the 500 level class on "The Science and Management of GHG" and works to incorporate the Climate Registry's best practices into NAU's GHG inventorying.
Scope 1 and Scope 2 GHG emissions::
| Performance Year | Baseline Year | |
| Scope 1 GHG emissions from stationary combustion | 20,573.89 Metric tons of CO2 equivalent | 18,466.58 Metric tons of CO2 equivalent |
| Scope 1 GHG emissions from other sources | 1,564.58 Metric tons of CO2 equivalent | 1,655.63 Metric tons of CO2 equivalent |
| Scope 2 GHG emissions from purchased electricity | 31,637 Metric tons of CO2 equivalent | 32,822.72 Metric tons of CO2 equivalent |
| Scope 2 GHG emissions from other sources | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Figures needed to determine total carbon offsets::
| Performance Year | Baseline Year | |
| Institution-catalyzed carbon offsets generated | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
| Carbon sequestration due to land that the institution manages specifically for sequestration | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
| Carbon storage from on-site composting | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
| Third-party verified carbon offsets purchased | 3,515 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
A brief description of the institution-catalyzed carbon offsets program:
A brief description of the carbon sequestration program and reporting protocol used:
A brief description of the composting and carbon storage program:
Dining Services composts an estimated 40,000 lbs of food waste and green materials each year.
Grounds composts all organic landscaping materials.
A brief description of the purchased carbon offsets, including third party verifier(s) and contract timeframes:
NAU purchases 10% of our energy from Green Power. Because our energy supplier already has some renewable energy in its mix, our total percentage of green power is 26.47%.
Figures needed to determine “Weighted Campus Users”::
| Performance Year | Baseline Year | |
| Number of residential students | 7,100 | 6,053 |
| Number of residential employees | 20 | 15 |
| Number of in-patient hospital beds | 0 | 0 |
| Full-time equivalent enrollment | 19,320 | 12,523 |
| Full-time equivalent of employees | 2,679 | 2,202 |
| Full-time equivalent of distance education students | 4,764 | 4,104 |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2012 | June 30, 2013 |
| Baseline Year | July 1, 2004 | June 30, 2005 |
A brief description of when and why the GHG emissions baseline was adopted:
2005 has been the used baseline year in our last two STARS submissions.
Gross floor area of building space, performance year:
Floor area of energy intensive building space, performance year:
| Floor Area | |
| Laboratory space | 90,301 Square feet |
| Healthcare space | 20,706 Square feet |
| Other energy intensive space | 144,104 Square feet |

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:
As part of Northern Arizona University's efforts to reduce costs and emissions associated with energy waste, Facility Services contracted NORESCO to provide and implement energy conservation measures (ECMs). This 15-year Energy Savings Performance Contract pays for the upgrades with cost avoidance generated by the ECMs, saving approximately $1,500,000 annually.
Yellow Bike Program encourages students to ride bikes
Green Fund Projects funds projects that reduce NAU's carbon footprint
Campus gardens support locally grown food
