Corporate greenhouse gas (GHG) emissions accounting seeks to provide an estimate for the GHG emissions attributable to an entity, such as an electric company or combined utility. GHG emissions accounting relies on voluntary guidance designed to enable the development of high-quality emissions inventories. However, when leading guidance documents lack consensus or sufficient specificity, entities may apply differing methods to complete their GHG emissions inventory, raising concerns for inventory quality. This EPRI report aims to illuminate existing challenges faced by electric companies and combined utilities when developing their corporate GHG emissions inventories. By articulating these challenges, electric companies can better identify issues and engage with entities that develop and maintain GHG emissions accounting guidance and other stakeholders to develop solutions that address these challenges.
