According to the GHG Protocol, the two primary methods for calculating value chain emissions are spend-based and activity-based.

  • The spend-based method multiplies the monetary value of a purchased good or service by an emission factor - the number of emissions produced per financial unit- which estimates the emissions produced.
  • The activity-based method involves the collection of more data, both internally and through suppliers. This method benefits a company's consumption or usage data on hand or that its suppliers have provided. The data, such as the litres of fuel burned by a vehicle or the kilogramme of plastic waste generated in operations, is multiplied by the emission factors of the activities to calculate the estimated emissions.
