Does the GHG Protocol set a materiality threshold?
A materiality threshold establishes an acceptable percentage (or absolute quantity) difference between the company’s emissions inventory and the verifier’s belief of what the company’s emissions would be if all omitted sources were accounted for. For example, if a company does not include a certain set of sources that the verifier thinks should be included, and those sources are estimated to emit more than the materiality threshold, this would be material discrepancy and emissions from at least some of those sources would need to be inventoried.
