A brief description of when and why the GHG emissions baseline was adopted:

In an effort to capture a more complete picture of our emissions, we have included fleet, fugitive, and shuttle emissions for the first time under Scope 1 - other sources. These figures had not been included in the past because of missing or incorrect data dating back to FY 2006. Historically, the boundary for the University's STARS reports has been limited to the Charles River and Medical Campuses. This year, for the first time we have been able to capture emissions data from facilities off campus within New England. We intend to include Global Programs when that data becomes available in the coming years. 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.
