Scope 1 emissions are direct greenhouse gas emissions from sources owned or controlled by an organization. Onsite natural gas combustion in owned buildings represents direct emissions from stationary combustion sources that the organization owns and controls. The combustion process directly releases CO2 and other greenhouse gases into the atmosphere from company-owned equipment, making this a textbook example of Scope 1 emissions.

A. Electricity use in offices - This is Scope 2 (indirect emissions from purchased electricity).

B. Business travel on commercial airplanes - This is Scope 3 (indirect emissions from third-party transportation).

C. Generator fuel use at leased facilities - This is Scope 3 (emissions from assets not owned/controlled by the organization).
