Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	4,789.58 Metric tons of CO2 equivalent	7,002.20 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	June 1, 2021	June 1, 2009
End date	May 31, 2022	May 31, 2010

A brief description of when and why the GHG emissions baseline was adopted:

The Greenhouse Gas emissions baseline was adopted for Fiscal Year 2010 because that was the earliest that the College began accurately reporting through the Second Nature Reporting Platform. Fiscal Year 2010 also aligns with the best baseline year data for campus waste.

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	688	679
Number of employees resident on-site	16	16
Number of other individuals resident on-site	8	8
Total full-time equivalent student enrollment	1,126	1,305
Full-time equivalent of employees	251	314.33
Full-time equivalent of students enrolled exclusively in distance education	175	0
Weighted Campus Users	1,085.50	1,396.25

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	4.41 Metric tons of CO2 equivalent	5.02 Metric tons of CO2 equivalent

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

12.02

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

684,909 Gross square feet

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	1,176 Square feet
Healthcare space	2,570 Square feet
Other energy intensive space	112,040 Square feet

EUI-adjusted floor area, performance year:

804,441 Gross square feet

Metric used in scoring for Part 2

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

0.01 MtCO2e per square foot

A brief description of the institution’s GHG emissions reduction initiatives:

Since the baseline period, Catawba College has implemented a number of upgrades to reduce campus emissions. 170 kilowatts of behind-the-meter photovoltaic solar panels have been installed on campus rooftops, which reduce the College's demand for power generated off campus using more carbon-intensive generation methods. Solar water heating systems have been installed in numerous buildings, including Abernathy Gymnasium, the Hayes Field House, and Woodson, Stanback, and Barger-Zartman residence halls. These solar water heating systems reduce on-site natural gas usage. The College also benefits from the 16 geothermal wells that assist in heating and cooling many campus buildings. Geothermal wells eliminate the need for natural-gas-fired water heaters and HVAC units powered by electricity generated off campus. The College's dining hall has also upgraded its facilities to reduce energy use and has implemented diversion of food waste to Gallins Family Farm, a third-party composting contractor.
