How can organizations ensure the completeness of their carbon ledger

Updated 9/24/2025

Ensuring completeness in a carbon ledger involves capturing all significant sources of emissions within the organization’s operational boundaries. Organizations should start by identifying and categorizing emissions according to the Scope 1, 2, and 3 framework, which covers direct, energy indirect, and other indirect emissions respectively. It’s important to use comprehensive data collection methods and maintain thorough documentation for each emissions source. Engaging with departments across the organization, such as procurement, logistics, and facilities management, can help in identifying overlooked emissions sources. Regular audits and reviews of the carbon ledger can also ensure that all relevant data is captured and any discrepancies are addressed promptly. Adopting recognized standards, such as ISO 14064, can provide guidelines for maintaining completeness. This approach not only aids in accurate reporting but also supports strategic initiatives for emissions reduction. Sources: Greenhouse Gas Protocol, ISO 14064.
