What is Carbon Accounting?

Carbon accounting involves measuring a company’s Greenhouse Gas (GHG) emissions—the gases released from a company’s activities and operations. This process adheres to the GHG Protocol.

For first-time assessments, companies perform a ‘baseline emissions assessment,’ which identifies and quantifies all emissions sources. These include:

Direct emissions: From activities like burning fossil fuels (e.g., driving a car).

Indirect emissions: From activities such as electricity consumption, freight transportation, or the purchase of goods and services.
