本論文は、IFRSに専用基準がない中での炭素資産・負債の分類、認識、測定の概念的枠組みを提案する。IFRIC 3撤回後の3つのアプローチ(IAS 38、IAS 2、IAS 37)の比較分析により、資産と負債の評価の非対称性が財務結果に人工的な変動をもたらすことを示した。Engie、Enel、EDFの報告分析から、会計処理の多様性と低い比較可能性を確認し、カーボンニュートラル宣言がIAS 37上の構成義務となり得ると論じる。

English

This paper proposes a conceptual framework for classifying, recognizing, and measuring carbon assets and liabilities under IFRS, given the lack of a dedicated standard. A comparative analysis of three approaches (IAS 38, IAS 2, IAS 37) reveals that the asymmetry in asset and liability valuation creates artificial volatility in financial results. Case studies of Engie, Enel, and EDF confirm diverse accounting practices and low comparability. It also argues that public carbon neutrality declarations may qualify as constructive obligations under IAS 37, expanding the scope of recognized provisions.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではSSBJがサステナビリティ開示基準を策定中だが、本論文は財務会計上の炭素取扱いに焦点を当てており、有報や統合報告書における炭素関連の会計処理の整合性向上に示唆を与える。特に、カーボンニュートラル宣言の構成義務化は、日本の企業の開示実務に影響し得る。

In the global GX context

Globally, this paper addresses the persistent issue of inconsistent accounting for carbon instruments under IFRS, which undermines comparability for investors. It provides a systematic analysis of the three prevailing approaches and identifies financial reporting risks, contributing to the ongoing debate on whether a dedicated IFRS standard is needed. The findings are relevant for entities participating in emissions trading schemes and for standard-setters aiming to enhance transparency.

👥 読者別の含意

🔬研究者:Provides a structured comparison of accounting treatments for carbon instruments and identifies risks, serving as a foundation for further empirical or theoretical work.

🏢実務担当者:Offers guidance on selecting accounting policies for carbon assets and liabilities, highlighting potential pitfalls and the implications of constructive obligations from net-zero pledges.

🏛政策担当者:Demonstrates the need for a uniform IFRS standard on carbon accounting and provides evidence of current diversity in practice, supporting regulatory or standard-setting efforts.

📄 Abstract(原文)

Purpose. The purpose of this study is to develop a conceptual framework for the classification, recognition, and measurement of carbon assets and liabilities under International Financial Reporting Standards (IFRS) that reduces methodological uncertainty arising from the absence of a dedicated standard and provides a consistent basis for financial reporting by entities participating in emissions trading schemes. Results. The research has established that the absence of a specialised standard is a natural consequence of the withdrawal of IFRIC 3 in 2005 and the subsequent freezing of the IASB project on pollutant pricing mechanisms, which forced enterprises to develop their accounting policies independently based on analogies with related standards. A comparative analysis of the three main approaches, based on IAS 38, IAS 2, and IAS 37, showed that none of them provides a methodologically consistent reflection of carbon instruments. The key structural problem is the asymmetry in the valuation of the asset and the liability, which generates artificial volatility in financial results. Three categories of financial reporting risks have been identified: overstatement of assets, understatement of liabilities, and destabilisation of the capital structure. Analysis of the reporting of Engie, Enel, and EDF confirmed the diversity of accounting approaches and low comparability of reporting data in the absence of a single standard. It is substantiated that public declarations on achieving carbon neutrality can be qualified as constructive obligations under IAS 37, which significantly expands the scope of provisions subject to recognition in financial reporting. Scientific novelty. The theoretical justification for classifying approaches to carbon instruments under the IFRS framework has been deepened; the content of the concept of constructive obligation in relation to corporate climate declarations has been refined; and financial reporting risks arising from the volatility of carbon markets have been systematised. Practical value. The study’s results can be used by enterprises to inform their accounting policies for carbon instruments, by regulatory authorities to develop national standards for climate assets, and by the scientific community as a methodological basis for further research into ESG reporting and emissions accounting automation.
