Gross Scope 2 GHG emissions from imported thermal energy	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Total	19,380.82 Metric tons of CO2 equivalent	25,504 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	0 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

N/A

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	19,380.82 Metric tons of CO2 equivalent	25,504 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	July 1, 2017	July 1, 2009
End date	June 30, 2018	June 30, 2010

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

The baseline year was selected because it was the year in which the first greenhouse gas emissions inventory was completed. The year 2009-10 was selected because it was the most recent year for which data was available when the university signed the Second Nature Carbon Commitment in 2011. This is also the baseline year used in our previous (and first) STARS submission in 2017 and we believe that maintaining our original baseline will allow us to best track our progress over time.

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	2,596	1,940
Number of employees resident on-site	81	2
Number of other individuals resident on-site	2	2
Total full-time equivalent student enrollment	31,571	28,882
Full-time equivalent of employees	3,643.40	3,070
Full-time equivalent of students enrolled exclusively in distance education	1,928.20	0
Weighted Campus Users	25,635.90	24,451.50

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	0.76 Metric tons of CO2 equivalent	1.04 Metric tons of CO2 equivalent

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

27.52

Healthcare space	38,629 Square feet
Other energy intensive space	45,599 Square feet

EUI-adjusted floor area, performance year:

6,284,039 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 university installed a 4.75-megawatt solar photovoltaic energy system, constructed a net-zero energy classroom building, and renovated another building to LEED standards. We also launched a campus-wide building retro-commissioning project that aims to optimize energy conservation across all building floor space over a 10 year period. Additionally, we engaged in long-term planning for central plant infrastructure improvements including the retirement of aging infrastructure and retrofitting heating systems to include heat recovery chillers, which will help meet campus heating needs while also partially decarbonizing the centralized heating plant.

The university has also continued to encourage our campus community to shift toward more sustainable commuting modes. Programs include subsidized public transportation passes, improvements to bicycle infrastructure and wayfinding on and around campus, improved communication and marketing efforts to raise awareness about sustainable transportation programs, and the integration of the City of Long Beach's bike share program on campus grounds.
