• Credit Info

Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
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 GHG inventory verification process:
Documentation to support the GHG inventory verification process:
Gross Scope 1 GHG emissions, performance year:

	Weight in MTCO2e
Stationary combustion	183,930 Metric tons of CO2 equivalent Date Revised: March 3, 2023 Yale University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 222633 Metric Tons of CO2 Equivalent Explanation: Currently, we indicate that the hospital is not part of our institutional boundary (PRE-3), but the hospital IS part of our emissions boundary through The Climate Registry (TCR) which means it is included in the GHG data (it impacts our scope 2) and energy data we submitted. We realized this error in hindsight of our submission, as we had not worked with TCR when we submitted prior to 2022.
Other sources (mobile combustion, process emissions, fugitive emissions)	5,980 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
Gross Scope 2 GHG emissions, performance year (market-based):

	Weight in MTCO2e
Imported electricity	30,506 Metric tons of CO2 equivalent Date Revised: March 3, 2023 Yale University requested that AASHE Staff correct a mistake in this reporting field for the reason specified below. Previous Value: 31131 Metric Tons of CO2 Equivalent Explanation: Currently, we indicate that the hospital is not part of our institutional boundary (PRE-3), but the hospital IS part of our emissions boundary through The Climate Registry (TCR) which means it is included in the GHG data (it impacts our scope 2) and energy data we submitted. We realized this error in hindsight of our submission, as we had not worked with TCR when we submitted prior to 2022.
Imported thermal energy	0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
Gross GHG emissions from biogenic sources, performance year:

Purchased goods and services	Yes	164,766 Metric tons of CO2 equivalent

Other standard categories of air emissions identified in permits and/or regulations	10.40 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
