These different scopes are a categorization for the delimitation of CO2 emissions.
Scope 1: In the first category, direct emissions from the company's own sources or sources controlled by the company itself (company headquarters, vehicles, etc.) are determined.
Scope 2: In the second category, indirect CO2 emissions from the energy used by the company are aggregated.
Scope 3: Here, all other emissions are collected that are related to the company. However, these emissions are usually outside the direct control of the company. An example of this would be emissions generated by suppliers or by the use of the company's products. Nevertheless, these emissions should be considered, reported and actively contributed to by companies in order to reduce them.
