Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:
| Performance year | Baseline year | |
| Gross Scope 1 GHG emissions from stationary combustion | 233,296 Metric tons of CO2 equivalent | 280,414 Metric tons of CO2 equivalent |
| Gross Scope 1 GHG emissions from other sources | 13,146 Metric tons of CO2 equivalent | 12,859 Metric tons of CO2 equivalent |
| Gross Scope 2 GHG emissions from imported electricity | 101,506 Metric tons of CO2 equivalent | 158,578 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 | 347,948 Metric tons of CO2 equivalent | 451,851 Metric tons of CO2 equivalent |
Figures needed to determine net 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 | 33,231 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 |
| 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 | 33,231 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):
The University's landfill gas (LFG) project captures methane from the Orange County, NC landfill. The methane is then either destroyed by a flare or piped to an electric generating engine on the University's Carolina North campus. The engine creates electricity that is sold to Duke Energy. Carbon offsets are registered with the Climate Action Reserve and verified by a third party.
Adjusted net Scope 1 and Scope 2 GHG emissions:
| Performance year | Baseline year | |
| Adjusted net GHG emissions | 314,717 Metric tons of CO2 equivalent | 451,851 Metric tons of CO2 equivalent |
Start and end dates of the performance year and baseline year (or three-year periods):
| Performance year | Baseline year | |
| Start date | Jan. 1, 2019 | Jan. 1, 2007 |
| End date | Dec. 31, 2019 | Dec. 31, 2007 |
A brief description of when and why the GHG emissions baseline was adopted:
The first comprehensive GHG emissions inventory, including steam and electricity produced for and sold to the hospital and a full range of scope 3 emissions, was completed in calendar year 2007.

| Number of other individuals resident on-site | 198 | 0 |
| Total full-time equivalent student enrollment | 29,272 | 25,895.25 |
| Full-time equivalent of employees | 13,329 | 11,295.23 |
| Full-time equivalent of students enrolled exclusively in distance education | 1,007 | 1,164.25 |
| Weighted Campus Users | 33,536.25 | 29,154.92 |
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

A brief description of the institution’s GHG emissions reduction initiatives:
"Annual energy intensity (Btu/Gross Square Foot) has declined, pointing to the immense success of the Energy Conservation Measures (ECM) Program. Energy Services’ Cogeneration Systems continues to replace aged thermal piping systems in its network. This has led to, and will continue to result in, increased thermal efficiency. Chilled Water Systems continues to lower its emissions factor through an ongoing chiller update program. Aside from curbing energy demand on campus, fuel-switching has also played a notable role in reduced emissions over the last several years.
