Scopes of carbon emissions
Usually, greenhouse gas emissions are divided into multiple categories that correspond to different scopes of involvement in the emissions. An entity is responsible for all these emissions, but it may have different levels of control on the various scopes.
Scope 1: Direct emissions
This is the CO2 or other greenhouse gas (GHG) the organization emits directly. Examples: Direct fossil fuel burning, methane leak, etc.
Scope 2: Indirect emissions from energy consumption
This is the GHG emitted by consuming electricity, heat or steam that has been generated by another entity.
Scope 3: Other indirect emissions
This is all the other GHG emissions that result from the entity’s activities. Examples: purchase of raw materials, services, employee travel, logistics and transports, waste, use of sold products, etc.
