The three main emissions scopes are:

1. Scope 1 emissions are emissions that are directly produced by a company or organization. These emissions come from sources that are owned or controlled by the company, such as vehicles, boilers, and other types of machinery.

2. Scope 2 emissions are emissions that result from the generation of electricity, heat, or steam that a company or organisation uses, but which are not directly produced by the company. For example, if a company buys electricity from a utility, the emissions from the power plant that generated that electricity would be considered scope 2 emissions for the company.

3. Scope 3 emissions are all other indirect emissions that are a result of the activities of a company or organisation, but which occur outside of the organization’s direct control. These emissions can come from a wide variety of sources, such as the use of a company’s products, waste generated by a company, or the transportation of goods to and from the company’s facilities.
