Description
"Greenhouse gas emissions" are emissions in terms of tonnes of CO2 equivalent of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), nitrogen trifluoride (NF3) and sulphur hexafluoride (SF6).
"Scope 1 emissions" are GHG emissions generated from sources that are controlled by the company that issues the underlying assets.
Scope 1 direct GHG emissions are principally the result of the following types of activities
undertaken by the company:
- Generation of electricity, heat, or steam. These emissions result from combustion of fuels in
stationary sources, e.g., boilers, furnaces, turbines
- Physical or chemical processing.3 Most of these emissions result from manufacture or
processing of chemicals and materials, e.g., cement, aluminum, adipic acid, ammonia manufacture,
and waste processing
- 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.
