Part 1. Greenhouse gas emissions inventory

Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :

Yes

A copy of the most recent GHG emissions inventory:

Public_Verified_Emissions_Report.pdf

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

Stanford uses The Climate Registry’s (TCR) General Reporting Protocol to prepare and file its GHG emission inventories. The university has been reporting third-party-verified emissions inventories since 2006. The document uploaded above shows Stanford's third-party-verified Scope 1 & 2 emissions as reported through TCR for calendar year 2019. This information is also publicly available after registering for a free TCR login: https://www.theclimateregistry.org/our-members/cris-public-reports/

Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:

Yes

A brief description of the GHG inventory verification process:

Stanford verifies its Scopes 1 and 2 emissions inventory every year through an independent third party. This process follows TCR's General Verification Protocol. Please see more details on the verification protocol here: https://www.theclimateregistry.org/tools-resources/verification/general-verification-protocol/

The Scope 3 emissions are not verified following TCR's Verification Protocol. However, Scope 3 emissions were evaluated using calculation tools, such as SIMAP and the EPA Waste Reduction Model tool. Contracted consultants and internal professional reviewers at Stanford from the Office of Sustainability and Facilities Energy Management, which are teams outside of the Business Affairs group calculating the Scope 3 data, additionally reviewed the data inputs to verify the accuracy and reasonableness of the input data.

Total gross Scope 1 GHG emissions, performance year:

32,761.92 Metric tons of CO2 equivalent

Scope 2 GHG emissions

Gross Scope 2 GHG emissions, performance year (market-based):

	Weight in MTCO2e
Imported electricity	33,433.01 Metric tons of CO2 equivalent
Imported thermal energy	199.87 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:

GHG emissions from biomass combustion

Gross GHG emissions from biogenic sources, performance year:

15.02 Metric tons of CO2 equivalent

Scope 3 GHG emissions

Does the GHG emissions inventory include Scope 3 emissions from the following sources?:

	Yes or No	Weight in MTCO2e
Business travel	Yes	43,708 Metric tons of CO2 equivalent
Commuting	Yes	24,049 Metric tons of CO2 equivalent
Purchased goods and services	Yes	402,153 Metric tons of CO2 equivalent
Capital goods	Yes	394,556 Metric tons of CO2 equivalent
Fuel- and energy-related activities not included in Scope 1 or Scope 2	Yes	25,555 Metric tons of CO2 equivalent

Other sources	Yes	113,182 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:

994,156 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:

While the university has laid out a path to reducing scope 1 and 2 emissions, scope 3 emissions mitigation strategies are less clear. As a result, the university launched a new Scope 3 Emissions Program in 2021, sponsored by the Vice President of Business Affairs. Initial scope 3 emissions estimates were completed for a subset of scope 3 categories based on calendar year 2019 data using a blend of external calculation tools and custom internal methodologies. The "Stanford University CY19 Scope 3 Emissions Inventory" workbook attached in the "Additional documentation to support the submission" section contains more information on Stanford's holistic approach, as well as individual methodologies for specific scope 3 categories. More information on Stanford's Scope 3 Emissions Program can be found here: https://sustainable.stanford.edu/campus-action/energy/stanford-energy-system-innovations-sesi/emissions-inventory/scope-3-emissions

Part 2. Air pollutant emissions inventory

Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:

Yes

Annual weight of emissions for::

	Weight of Emissions
Nitrogen oxides (NOx)	7.96 Tons
Sulfur oxides (SOx)	0.08 Tons
Carbon monoxide (CO)	1.99 Tons
Particulate matter (PM)	0.46 Tons
Ozone (O3)	---
Lead (Pb)	0.00 Tons
Hazardous air pollutants (HAPs)	---
Ozone-depleting compounds (ODCs)	---
Other standard categories of air emissions identified in permits and/or regulations	0.77 Tons

Do the air pollutant emissions figures provided include the following sources?:

	Yes or No
Major stationary sources	Yes
Area sources	No
Mobile sources	No
Commuting	No
Off-site electricity production	No

None

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

Stanford uses EPA approved conversion factors to calculate emissions based on fuel usage for both permitted and exempt sources. The SOx data reported is for SO2. The data in Part 2 reported is from 2019 to align with the Part 1 data reported above.
