Scope 1 GHG Emissions
From Open Risk Manual
Definition
Scope 1 GHG Emissions. Direct GHG Emissions that occur from sources owned or controlled by the reporting entity (company, city etc)
City Protocol
GHG emissions from sources located within the city boundary.[1]
Corporate Protocol
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.
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.
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.
