Scope 1 GHG Emissions

Definition

Scope 1 GHG Emissions. Direct GHG Emissions that occur from sources owned or controlled by the reporting entity (company, city etc)

Examples

GHG Emissions Sources that are owned or controlled by the company are:

• Physical production in owned or controlled process equipment
• Generation of electricity, heat, or steam. These emissions result from combustion of fuels in stationary sources, e.g., boilers, furnaces, turbines
• Chemical processing. Most of these emissions result from manufacture or processing of chemicals and materials, e.g., cement, aluminum, adipic acid, ammonia manufacture, and waste processing
• Emissions from company owned vehicles
• Transportation of materials, products, waste, and employees. These emissions result from the combustion of fuels in company owned/controlled mobile combustion sources (e.g., trucks, trains, ships, airplanes, buses, and cars)
• Fugitive emissions. These emissions result from intentional or unintentional releases, e.g., equipment leaks from joints, seals, packing, and gaskets; methane emissions from coal mines and venting; hydrofluorocarbon (HFC) emissions during the use of refrigeration and air conditioning equipment; and methane leakages from gas transport.

Notes

• Direct CO₂ emissions from the combustion of biomass shall not be included in scope 1 but reported separately.
• 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.

As defined in

Calculation

For most small to medium-sized companies and for many larger companies, scope 1 GHG emissions will be calculated based on the purchased quantities of commercial fuels (such as natural gas and heating oil) using published emission factors.
