📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではSSBJ開示やサプライチェーン排出量算定の負担が課題であり、E-ledgersはリアルタイムで正確なScope 3データを提供し、開示の信頼性向上とコスト削減に寄与する可能性がある。

In the global GX context

Globally, this aligns with ISSB and CSRD demands for accurate, verifiable emissions data. E-ledgers could transform disclosure from estimates to transaction-based accounting, enhancing comparability and reducing greenwashing.

👥 読者別の含意

🔬研究者:Provides a novel accounting framework for real-time carbon tracking, opening research avenues in accounting and climate disclosure.

🏢実務担当者:Offers a potential infrastructure for automating Scope 3 reporting and improving data accuracy for disclosure.

🏛政策担当者:Highlights the need for regulatory support and standardization to enable E-ledgers implementation.

📄 Abstract(原文)

In prior publications, we introduced a global system of interconnected E-ledgers that produces—in as close to real time as practicable—accurate, comparable, and verifiable accounts of the cradle-to-gate (net) greenhouse gas emissions in any product or service that transacts in the economy. In this paper, we delve more deeply into the accounting infrastructure required for the E-ledgers system, including the specific journal entries for recording E-liabilities and E-assets. We explain how the E-ledgers of different entities in the economy articulate with each other and how they connect with jurisdictional E-ledgers that record emissions from end consumers. These entity and jurisdictional E-ledgers can be aggregated into a geological master ledger that tracks anthropogenic GHG emissions and removals, as debits and credits, to a geological carbon equity account. We also provide summary insights from computational technology and pilot studies to guide rapid and cost-effective E-ledgers deployment at scale. This paper was accepted by Shiva Rajgopal, accounting. Funding: Funding for R. S. Kaplan’s research was provided by Harvard Business School. K. Ramanna receives a salary from Oxford University. The authors are co-founders of E-ledgers Institute, a nonprofit organization, which seeks to implement the E-ledgers carbon accounting method in practice.
