Definition
This metric tracks the mass of Scope 1 greenhouse gases emitted by the company, as measured in metric tons (t) of carbon dioxide (CO2) equivalent in the last calendar year.
Expanded Definition
Scope 1 emissions are defined by the GHG Protocol as direct emissions that “occur from sources that are owned or controlled by the company, for example, emissions from combustion in owned or controlled boilers, furnaces, vehicles, etc.; emissions from chemical production in owned or controlled process equipment.”
- Also included are emissions from company owned/controlled mobile combustion sources (e.g airplanes, trucks, trains, ships, buses, and cars), which are used to transport materials, products, waste, and employees.
- According to the GHG Protocol, “[d]irect CO2 emissions from the combustion of biomass shall not be included in scope 1 but reported separately. The GHG Protocol specifies that “GHG emissions not covered by the Kyoto Protocol, e.g. CFCs, NOx, etc. shall not be included in scope 1 but may be reported separately.“
- GHG Protocol provides tools, step by-step guidance, and electronic worksheets to help users calculate GHG emissions from specific sources or industries.
