Scope 3 GHG emissions are all indirect emissions not covered in Scope 2. Consistent with the WRI Corporate Value Chain (Scope 3) Standard, Scope 3 GHG emissions sources include:
Upstream Scope 3 emissions
Purchased goods and services
Capital goods
Fuel- and energy-related activities (not included in scope 1 or scope 2)
Upstream transportation and distribution
Waste generated in operations
Business travel
Commuting (employee and student)
Upstream leased assets
Downstream Scope 3 emissions
Downstream transportation and distribution
Processing of sold products
Use of sold products
End-of-life treatment of sold products
Downstream leased assets
Franchises
Investments
This metric is looking for the amount of greenhouse gas (GHG) emissions (in metric tons of CO2 equivalent) generated from waste generated in operations that the institution is indirectly responsible for during the performance year:
For WikiRate researchers:
Institutions who report to the STARS program are listed on the STARS Participants & Reports website.
Use the institution Index, CTRL F, or Command F to search for the institution you want to research
By clicking on the hyperlinked name of the institution, you will be redirected to the page where all their STARS reports are listed. You can select either the most recent report, or one of the older reports to start tracking their performance over time.
NB: While the values in the reports might apply to different points in time (performance year, baseline year, most recent, etc.), the submission date of the report should be listed as the “year” on WikiRate. This is to ensure that reports of the same submission year can be compared. Any time specific information for the individual values should be included in the comment to that specific metric value.
To narrow down your search, navigate the reports’ index using the Reporting Category - Operations - and Credit Category - Air & Climate - to finally select the Credit Title: Greenhouse Gas Emissions.
You should now be on the report page that discloses the amount of greenhouse gas (GHG) emissions (in metric tons of CO2 equivalent) generated from waste generated in operations that the institution is indirectly responsible for during the performance year. To locate the exact value you can search the page using CTRL F or Command F with keywords like Scope 3 and waste.
Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value
Add comments to include details of simple or complex calculations or conversions made to determine the metric value and document any relevant contextual information, like:
the start and end date of the performance year
Further guidance on how to research values is available here, including detailed guidance on adding, editing and checking metric values.
STARS compliance guidance for institutions:
Timeframe
Performance Year
Institutions should report the most recent data available from the three years prior to the anticipated date of submission. Institutions may use the most recent single year for which data is available or an average from throughout the period. Institutions may choose the annual start and end dates that work best with the data they have (e.g., fiscal or calendar year), as long as data are reported from a consecutive 12-month (or 3-year) period.

Sampling and Data Standards
To conduct a GHG emissions inventory, campuses may use the Campus Carbon Calculator/CarbonMAP, the Scope 3 Evaluator tool, and/or any methodology or calculator that is consistent with the World Resources Institute (WRI) Greenhouse Gas Protocol Corporate Standard and the Scope 3 calculation guidance provided by WRI.
