Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	49,130.76 Metric tons of CO2 equivalent	76,574.24 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, 2023	July 1, 2011
End date	June 30, 2024	June 30, 2012

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

It's been a few years, but BGSU used to have a consulting firm called Sightlines compile an annual Sustainability Report for BGSU. We have since assumed responsibility for our own climate data reporting through SIMAP. For the sake of this submission, we have referred to Sightlines' decision to choose FY12 as our baseline year. Their 2020 Report provided the following rationale:

"The included energy efficiency investments are over a 7 year period, between FY12 and
FY19
• A simple payback calculation would measure the impact of a single investment. For this calculation,
we were looking at campus-wide projects over multiple years, and therefore normalized the
investment across 5M+ square feet and 7 years
• If building level consumption is provided, we can calculate more specific payback for individual
projects
• 2012 was chosen as the base year for electricity consumption to account for the 7 year
investment period"

2012 was also the year that BGSU commited to the Presidents' Climate Commitment, so FY12 provides a good benchmark against which to measure our 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	5,451	6,671
Number of employees resident on-site	17	30
Number of other individuals resident on-site	1	0
Total full-time equivalent student enrollment	13,793	15,755
Full-time equivalent of employees	2,186	1,956
Full-time equivalent of students enrolled exclusively in distance education	988	0
Weighted Campus Users	12,611.25	14,958.50

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	3.90 Metric tons of CO2 equivalent	5.12 Metric tons of CO2 equivalent

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

23.90

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

5,231,570.67 Gross square feet

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	389,202.26 Square feet
Healthcare space	2,745.37 Square feet
Other energy intensive space	0 Square feet

EUI-adjusted floor area, performance year:

6,015,465.93 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
