Part 1. Greenhouse gas emissions inventory

Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :

Yes

A copy of the most recent GHG emissions inventory:

ghg_2020_brochure_print_final.pdf

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

MIT's greenhouse gas inventory assesses the quantity of greenhouse gases (GHG) the Institute produces, and identifies the emissions’ sources. The MIT Office of Sustainability (MITOS) uses the Operational Control Approach as defined by the World Resources Institute’s GHG Protocol, the worldwide corporate and campus standard for greenhouse gas emissions measurement. The GHG Protocol defines emissions using three "scopes," which are detailed below along with the specific greenhouse gases measured.

MIT currently measures emissions from owned and leased academic buildings, fugitive gases, and campus vehicles. The emissions from these activities are calculated using the Campus Carbon Calculator - the most commonly used inventory tool for universities - which converts data into a single unit: metric tons of carbon dioxide equivalent (MTCO2e).

MITOS conducts and manages the annual GHG inventories in collaboration with the Department of Facilities and the Environment, Health and Safety Office. The MIT Office of Treasury and Planning audits the findings for accuracy. MIT plans to expand the scope of its GHG inventory in the future and actively engage the academic and operational community in the use, refinement, and application of the inventory in order to reduce the carbon intensity of the campus.

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?:

Yes

A brief description of the GHG inventory verification process:

Underlying fuel use data audited by the Office of the Treasury and Planning. Regulatory GHG Inventory submitted to state authorities is audited by a certified third party.

Scope 3 GHG emissions

Does the GHG emissions inventory include Scope 3 emissions from the following sources?:

	Yes or No	Weight in MTCO2e
Business travel	No	---
Commuting	No	---
Purchased goods and services	No	---
Capital goods	No	---
Fuel- and energy-related activities not included in Scope 1 or Scope 2	Yes	4,279 Metric tons of CO2 equivalent
Waste generated in operations	No	---
Other sources	Yes	4,582 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:

8,861 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:

In 2020, the MIT Office of Sustainability expanded upon a multi-year effort to build a preliminary picture of the Institute’s Scope 3, or indirect, GHG emissions. This is done to inform MIT’s total greenhouse gas emissions activities (Scopes 1 + 2 + 3) and explore where strategic opportunities may exist to reduce emissions beyond what MIT is currently tracking. This effort is developing additional emissions data associated with MIT’s purchased goods and services, MIT-sponsored travel, commuting, and capital goods (furniture, fixtures, tools, etc.) using the WRI & WBCSD GHG Protocol for Scope 3 framework.
