"---" indicates that no data was submitted for this field

Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:
Performance year Baseline year
Gross Scope 1 GHG emissions from stationary combustion Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Total Metric tons of CO2 equivalent Metric tons of CO2 equivalent

Figures needed to determine net carbon sinks:
Performance year Baseline year
Third-party verified carbon offsets purchased Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Institution-catalyzed carbon offsets generated Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Carbon storage from on-site composting Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Carbon sold or transferred Metric tons of CO2 equivalent Metric tons of CO2 equivalent
Net carbon sinks Metric tons of CO2 equivalent 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 Metric tons of CO2 equivalent 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.

Figures needed to determine “Weighted Campus Users”:
Performance year Baseline year
Number of students resident on-site
Number of employees resident on-site
Number of other individuals resident on-site
Total full-time equivalent student enrollment
Full-time equivalent of employees
Full-time equivalent of students enrolled exclusively in distance education
Weighted Campus Users

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:
Performance year Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user Metric tons of CO2 equivalent Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

Gross floor area of building space, performance year:
1,810,103.66 Gross square meters

Floor area of energy intensive building space, performance year:
Floor area
Laboratory space 235,571.26 Square meters
Healthcare space 18,703.70 Square meters
Other energy intensive space 124,943.76 Square meters

EUI-adjusted floor area, performance year:
2,443,597.32 Gross square meters

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
0.13 MtCO2e per square meter

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.
