Scope 1 and Scope 2 GHG emissions
Gross GHG emissions
Performance year | Baseline year | |
Gross Scope 1 GHG emissions from stationary combustion | 20,626.27 Metric tons of CO2 equivalent | 18,466.58 Metric tons of CO2 equivalent |
Gross Scope 1 GHG emissions from other sources | 1,675.45 Metric tons of CO2 equivalent | 1,655.63 Metric tons of CO2 equivalent |
Gross Scope 2 GHG emissions from imported electricity | 23,751.86 Metric tons of CO2 equivalent | 32,822.72 Metric tons of CO2 equivalent |
Gross Scope 2 GHG emissions from imported thermal energy | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Total | 46,053.58 Metric tons of CO2 equivalent | 52,944.93 Metric tons of CO2 equivalent |
Carbon sinks
Performance year | Baseline year | |
Third-party verified carbon offsets purchased | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Institution-catalyzed carbon offsets generated | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Carbon storage from on-site composting | 14.18 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Carbon storage from non-additional sequestration | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Carbon sold or transferred | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
Net carbon sinks | 14.18 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
If total performance year carbon sinks are greater than zero, provide:
Compost: NAU tracks the weight of compost generated each year. This weight is entered into SIMAP, and the report generates MTCDE. FY 2023, we composted 96,476.00 pounds of organic waste from waste to soil, which is then sold to community members or used around campus.

A brief description of the institution’s GHG emissions reduction initiatives:
The campus achieved a 13.04% reduction in overall emissions, with a significant 27.63% decrease in emissions from imported electricity. Despite a rise in student population by 3,632 and campus size, emissions per person and per square footage decreased. In 2023, NAU made investments in energy reduction, appointing key roles like Chief Sustainability Officer, Sustainability Data Analyst, Energy/Water Manager, and Conservation Program Coordinator. These roles will focus on cutting carbon footprint through behavior change and data-backed improvements. A Green Seed Investment Fund of $500,000 was initiated for greenhouse gas reduction initiatives. Upgrading campus meters in FY 2024 is planned to enhance consumption tracking for effective reduction efforts.
Note: AZNM's emissions factor has dropped due to the closure of coal plants in the past 15 years.
