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

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.

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.
