Scope 1 and Scope 2 GHG emissions

Gross GHG emissions

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

Carbon sinks

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

If total performance year carbon sinks are greater than zero, provide:

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 GHG emissions

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

Performance and baseline periods

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.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

	Performance year	Baseline year
Number of students resident on-site	8,554	8,541
Number of employees resident on-site	17	0
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

Metrics used in scoring for Part 1

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	9.38 Metric tons of CO2 equivalent	15.50 Metric tons of CO2 equivalent

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

39.45

Part 2. GHG emissions per unit of floor area

Performance year floor area

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

Metric used in scoring for Part 2

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.
