All GHG emissions were calculated with the EPA Simplified GHG Emissions Calculator in accordance with the GHG Protocol Corporate Accounting and Reporting Standard.

​

Scopes 1 & 2
Due to the nature of our remote working staff, BCS does not have any Scope 1 or Scope 2 emissions to report for the Calendar Year 2022. Government-owned and operated buildings were not included as BCS properties as they are not owned or operated by BCS staff. A small number of our staff does occupy a rented office space infrequently however, after reaching out to the building's leasing office, we were informed that they do not submeter individual offices. Therefore, BCS does not have any Scope 1 or 2 emissions as the building owner does not specifically attribute any electricity or fuel use to our space.
 
Scope 3
BCS contributed 18.45 metric tons of carbon dioxide equivalent (CO2-e) through business travel and employee commuting in Calendar Year 2022. Travel and commute data was self-attested by the employees that took these trips, and when calculating commuting data it was assumed that the year included 50 working weeks. 61% of our GHG emissions were from employees commuting to on-site work. The other 39% of our GHG emissions were due to employee travel for various company duties and events. 
​​

All of our scope 3 emissions come from commuting and related business travel. A breakdown of these emissions can be found in the attached workbook.
