A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory, including how the institution accounted for each category of Scope 3 emissions reported above:

The leading methodology was developed in 2004 as a partnership between the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD). The success and usefulness of their Greenhouse Gas Protocol is evidenced by its adaptation to protocols employed by the US Environmental Protection, the International Standards Organization (ISO), and others with minor modifications.

In an effort to comply with the industry’s best practices, and to prepare for state or federal regulation, we have adhered to this WRI/WBCSD standard as closely as possible,
taking guidance from EPA, ISO, and Climate Registry documentation where appropriate. In some cases, the established protocols did not fit our process or infrastructure. Where possible, we developed emission models to improve upon the recommended methodology.


Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
No

A brief description of the internal and/or external verification process:
---

Documentation to support the internal and/or external verification process:
---

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes

Gross Scope 1 and Scope 2 GHG emissions:
Performance Year Baseline Year
Gross Scope 1 GHG emissions from stationary combustion 274,613 Metric Tons of CO2 Equivalent 280,392 Metric Tons of CO2 Equivalent
Gross Scope 1 GHG emissions from other sources 5,546 Metric Tons of CO2 Equivalent 7,230 Metric Tons of CO2 Equivalent
Gross Scope 2 GHG emissions from purchased electricity 129,131 Metric Tons of CO2 Equivalent 163,788 Metric Tons of CO2 Equivalent
Gross Scope 2 GHG emissions from other sources 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Total 409,290 Metric Tons of CO2 Equivalent 451,410 Metric Tons of CO2 Equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year Jan. 1, 2015 Dec. 31, 2015
Baseline Year Jan. 1, 2007 Dec. 31, 2007

A brief description of when and why the GHG emissions baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

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 total carbon offsets:
Performance Year Baseline Year
Third-party verified carbon offsets purchased (exclude purchased RECs/GOs) 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Institution-catalyzed carbon offsets generated 40,409 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Carbon sequestration due to land that the institution manages specifically for sequestration 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Carbon storage from on-site composting 417 Metric Tons of CO2 Equivalent 511 Metric Tons of CO2 Equivalent
Carbon offsets included above for which the emissions reductions have been sold or transferred by the institution 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Net carbon offsets 40,826 Metric Tons of CO2 Equivalent 511 Metric Tons of CO2 Equivalent

A brief description of the offsets in each category reported above, 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.

University composted yard waste (1637.2 tons) and food waste (679.4 tons) are equivalent to 297.7 Composted MTCO2e and 122.29 MTCO2e respectively using the EPA's WARM model. This results in a total of 417 MTCO2e that is offset due to composting and would not otherwise have been captured preventing release to the atmosphere.


Emissions reductions attributable to Renewable Energy Certificate (REC) or Guarantee of Origin (GO) purchases:

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:

"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.

A comprehensive indoor and outdoor recycling and composting program captured 47% of campus discards in FY 2016. Food waste from UNC dining halls, catering, and several high volume Green Events venues is routinely recovered. "
