A brief description of the methodology and/or tool used to complete the GHG emissions inventory, including how the institution accounted for each category of Scope 3 emissions reported above:
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?:
A brief description of the internal and/or external verification process:

	Emissions
Business travel	34,504 Metric tons of CO2 equivalent Date Revised: Aug. 15, 2022 University of Colorado Boulder requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 241792 Metric Tons of CO2 Equivalent Explanation: In 2021 a suspected error was discovered in this individual field reported in 2017. However, the EC GHG team could not source the original meta data from which the reported value was calculated. Upon request, CU Purchasing (PSC) was able to find and send additional records to us. Those data enabled a recalculated result that aligns more consistently with historic CU values and those of similar sized institutions we reviewed. Therefore, after consulting with STARS staff, we are submitting a correction to more accurately reflect our air travel trends and emissions for the record.
Commuting	2,618 Metric tons of CO2 equivalent
Purchased goods and services	---
Capital goods	---
Fuel- and energy-related activities not included in Scope 1 or Scope 2	---
Waste generated in operations	1,609 Metric tons of CO2 equivalent
Other categories	---
