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

	Performance year	Baseline year
Gross Scope 1 GHG emissions from 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.	215,761 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: 244582 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.

Gross Scope 2 GHG emissions from 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.	50,970 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: 51650 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.
