Scope 1 and Scope 2 GHG emissions

Gross GHG emissions

Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:

Gross Scope 1 GHG emissions from other sources 1,768.18 Metric tons of CO2 equivalent 2,411.62 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity 33,305.25 Metric tons of CO2 equivalent 36,574.57 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Total 59,646.58 Metric tons of CO2 equivalent 61,423.86 Metric tons of CO2 equivalent

Carbon sinks

Figures needed to determine net carbon sinks:

A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):
N/A

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 59,630.88 Metric tons of CO2 equivalent 61,409.46 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, 2021 July 1, 2018
End date June 30, 2022 June 30, 2019

A brief description of when and why the GHG emissions baseline was adopted:
Fiscal year 2019 was adopted as a reset of George Mason's baseline based on the accuracy of data available. It is ambitious to reset, as per sq ft reductions are discounted from the 2006 baseline to FY2019, but for accuracy and proper assessment going forward, Mason has decided to use FY19.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

Number of students resident on-site 5,293 6,121
Number of employees resident on-site 17 17
Number of other individuals resident on-site 0 0
Total full-time equivalent student enrollment 32,344 31,271
Full-time equivalent of employees 4,897 4,517
Full-time equivalent of students enrolled exclusively in distance education 5,151 952
Weighted Campus Users 25,395 27,661.50

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

897,987.02 Gross square meters

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
0.07 MtCO2e per square meter

A brief description of the institution’s GHG emissions reduction initiatives:
Mason has pursued several small-scale solar projects as living laboratory projects led by students, as well as hired consultants to create an Energy Plan for carbon reduction to include larger-scale renewable and efficiency projects. We have worked to implement operations and maintenance practices that improve energy efficiency and automation, as well as water conservation. We have increased back-of-house composting and started front-of-house composting pilot stations. Mason also conducted a fleet management study and we are implementing recommendations like fleet car sharing, and are working toward EV transitions. We are also optimizing efficiency for waste trucks and routes by installing smart waste stations around the exterior of campus, and we have written a reduction in shipping material and trips into contract language during requests for proposal engagements with vendors. We are working with vendors to reduce waste, including food waste and wasteful single-use plastics, as well as promoting and requiring the use of materials and products that have a higher percent recycled content or greater ability to be recycled at the end of life to promote product circularity. We have also updated our Design Standards and Design Guidelines with similar language and criteria requirements for various equipment and purchased goods.
