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	July 1, 2018	July 1, 2009
End date	June 30, 2019	June 30, 2010

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

The University of San Diego GHG emissions baseline was adopted and approved in the university's Fall 2016 Climate Action Plan. Using 2010 as a baseline, the original goal was to reduce the university’s emissions and environmental footprint with target years of 2020, 2030, and 2035. The targets to reduce emissions levels were informed by and consistent with the City of San Diego’s Climate Action Plan, including baselines and target years. However, in October 2019, USD President Dr. James Harris committed to climate neutrality by 2035, so the USD Climate Action Plan will be revised to reflect this new goal. The original 2010 baseline will be retained to track progress.

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	2,641	2,543
Number of employees resident on-site	20	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	8,328	6,897
Full-time equivalent of employees	2,116.40	1,737
Full-time equivalent of students enrolled exclusively in distance education	377.70	122.30
Weighted Campus Users	8,215.28	7,019.53

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	1.28 Metric tons of CO2 equivalent	2.33 Metric tons of CO2 equivalent

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

44.94

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

3,315,288 Gross square feet

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	23,769 Square feet
Healthcare space	4,528 Square feet
Other energy intensive space	5,218 Square feet

EUI-adjusted floor area, performance year:

3,377,100 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:

0.00 MtCO2e per square foot

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

The primary focus of GHG emissions reductions has been energy efficiency. Since 2010, USD has reduced its energy consumption 35.5% despite increasing building square footage and enrollment. The Climate Action Plan completed in 2016 set out goals for further reductions, but those will be revised in 2020 after Dr. Harris signed the Climate Commitment and pledged that USD will achieve climate neutrality by 2035.
