Part 1. Greenhouse gas emissions inventory
Yes
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:
Boston University (BU) used the University of New Hampshire's Sustainability Indicator Management and Analysis Platform (SIMAP) to calculate greenhouse gas emissions. Prior to BU's FY2018 STARS submission, we used an institutional boundary that included just the Charles River and Medical Campuses. Starting in our FY2018 STARS submission, we have expanded our institutional boundary and associated metrics to off-campus facilities within New England. In addition, on June 1, 2018, Wheelock College merged with BU, becoming the Fenway Campus; this campus will also be included in our institutional boundary for the last month of the 2018 fiscal year (FY). We intend to include Global Programs when that data becomes available in the coming years.
We have uploaded FY 2006 through 2020 data into SIMAP. BU uses an FY2006 baseline year for all sustainability-metric data. We account for Scope 1 emissions of (1) stationary combustion of fossil fuels on campus, (2) transportation-related fossil fuel consumption, (3) emissions from refrigerants & chemicals [until FY2018], and (4) fertilizers, Scope 2 emissions of purchases of (5) electricity and (6) steam.
We included emissions from the Boston University Shuttle (BUS) for the first time in our 2018 STARS submission. In that submission, we included the same amount of emissions in our baseline year (FY06) as our performance year (FY16). In our FY2018 STARS submission, we include more precise estimates of the emissions from the BUS. Specifically, we used nearly complete BUS fuel consumption data from FY13-18 to estimate FY06-12 using a linear regression model. The FY13-18 data had 5 months of missing data; we estimated the fuel consumption of these missing months as the average of the other four years of data for the specific month missing.
Regarding water consumption: We used BU's Budget Planning and Business Affairs (BPBA) and Facilities Management and Operations (FMO) records of water consumption on campus.

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
BU visits all of its buildings on campus, inventories all emission producing equipment and calculates potential emissions using emissions guarantees and EPA-approved emission factors for criteria and GHG emissions. Actual emissions are calculated using the fuel use or run times of each piece of emission producing equipment.
No accounting was conducted for "Refrigerants & Chemicals". As of FY2019, Boston University is no longer required by the Massachusetts Department of Environmental Protection (MassDEP) to report on "Refrigerants & Chemicals".
