Proto-Standards for Carbon Accounting using E-ledgers
Launch of the E-asset Proto-Standard for Carbon Accounting
The E-ledgers Institute is pleased to announce the release of the Proto-Standard for E-assets, a major milestone in the development of the E-ledgers framework for carbon accounting and auditing.
The E-asset Proto-Standard establishes accounting and auditing principles under which carbon removals may be recognized as E-assets on an E-ledger and netted against E-liabilities. It defines when a unit of atmospheric carbon removal qualifies as a ledger-eligible asset and specifies how such assets are recorded, transferred, monitored, impaired, and ultimately netted within the E-ledgers system.
The proto-standard addresses a fundamental need in today’s carbon markets. While registry certificates may document that a carbon removal event has occurred, they do not necessarily constitute an asset that can persist through time, transfer between entities, or be netted against emissions liabilities. The E-asset Proto-Standard establishes the conditions under which carbon removals can be recognized and managed as accounting assets within a robust carbon accounting framework.
To qualify as an E-asset, a carbon removal must satisfy defined criteria related to: the likelihood that the removal has occurred or will occur; accurate measurement and independent verification of the removal amount; and the expected duration and reliability of carbon storage. By defining these criteria, the proto-standard clarifies when carbon removals can be recorded as tradable or nettable E-assets.
A Complement to the E-liability Proto-Standard
The E-asset Proto-Standard applies specifically to the removal of greenhouse gases that have already entered the atmosphere. Emissions reductions and the accounting of embedded emissions throughout supply chains are addressed separately through the E-liability Proto-Standard.
The E-liability method tracks the cradle-to-gate emissions embedded in products and services as they move through the economy, while the E-asset framework establishes how verified carbon removals can be recognized and applied against those liabilities. Together, they form the basis of the broader E-ledgers system.
Together, the E-asset and E-liability Proto-Standards serve a role analogous to financial accounting standards such as Generally Accepted Accounting Principles (GAAP) in financial markets. They establish foundational rules for recognizing and recording carbon-related assets and liabilities, enabling transparent, auditable, and interoperable carbon accounting systems.
