Has the institution conducted a GHG emissions inventory that includes all Scope 1 and 2 emissions? :
Yes

Does the institution’s GHG emissions inventory include all, some or none of its Scope 3 GHG emissions from the following categories?:
All, Some, or None
Business travel Some
Commuting Some
Purchased goods and services Some
Capital goods None
Waste generated in operations None
Fuel- and energy-related activities not included in Scope 1 or Scope 2 None
Other categories None

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, including how the institution accounted for each category of Scope 3 emissions reported above:

Yale began reporting on its GHG emissions in 2005, when it set a goal to reduce emissions by 43% from 2005 levels by 2020. These emissiosn were defined as purchased electricity that passes through Yale's Central Power Plant, Sterling Power Plant, and Central Campus Chiller Plant, along with all gas and oil that is consumed by Yale's Central Power Plant and Sterling Power Plant.
Yale also recently began reporting its GHG emissions to The Climate Registry (TCR), using TCR's General Reporting Protocol. Emissions are quantified using standardized methodologies, and is consistent with the World Resources Institute's Greenhouse Gas Protocol Corporate Standard, which is recognized as an international best practice. We will be transitioning solely to TCR in 2020, which is the end date for our current GHG emissions reduction goal.


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?:
No

A brief description of the internal and/or external verification process:

The inventory conducted for The Climate Registry has been verified by an external third party. The inventory included here (which is using the methodology consistent with our 2005 baseline) has not been externally verified.

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes

Number of other individuals resident on-site and/or in-patient hospital beds was not available for FY05, so we entered 0.

Scope 2 GHG emissions were much lower for FY17 in FY15. In FY15, all of our Central Power Plant turbines were down and being replaced; consequently we had to buy from the grid. By FY17, the turbines were back up and running.
