本論文は、ESRSに基づく2024年度サステナビリティ報告書とIFRS財務諸表の「会計連結性」を、ポルトガル上場22社全社について検証する。4次元26項目の会計連結性指数（ACI）を開発し、スコアは17.1〜94.8（平均57.1）とばらつきを確認。EUタクソノミー指標と財務数値の定量的トレーサビリティは広く見られる一方、会計上の見積りや測定への実質的統合は7社に限られ、開示連結性と会計連結性の区別を提唱する。
English
This study assesses accounting connectivity between FY2024 ESRS sustainability statements and IFRS financial statements across all 22 Portuguese listed companies. Using a 26-item Accounting Connectivity Index across four dimensions, it finds ACI scores of 17.1–94.8 (mean 57.1). Quantitative traceability (largely EU Taxonomy-to-financial links) is widespread, but substantive integration into accounting assumptions and measurement is concentrated in only seven firms, supporting a distinction between disclosure connectivity and true accounting connectivity.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準の導入と有報・統合報告書でのサステナビリティ情報と財務情報の「連結性」確保が日本企業の実務課題となる中、ESRS先行適用の実証エビデンスは、日本版開示の質的深度を測る物差しとして直接参考になる。定量トレーサビリティと会計統合の乖離という知見は、SSBJ対応の実効性評価に示唆を与える。
In the global GX context
As ISSB/SSBJ adoption advances, connectivity between sustainability and financial reporting is a central disclosure-quality question. This paper offers early empirical evidence from the first ESRS reporters, providing a replicable, sector-neutral framework that complements TCFD/ISSB connectivity debates and can inform CSRD implementation reviews and global disclosure scholarship.
👥 読者別の含意
🔬研究者:開示連結性と会計連結性を区別する測定フレームワーク（ACI）は、サステナビリティ開示研究の新たな実証手法として活用できる。
🏢実務担当者:ESRS/SSBJ対応で、定量的な紐付けにとどまらず会計上の見積り・測定への統合をどう確保するかの実務チェックリストとして使える。
🏛政策担当者:開示連結性の形式的達成と実質的会計統合の乖離は、SSBJ/CSRDの実効性評価と今後の基準設計に重要な論点を提供する。
📄 Abstract（原文）
This study examines accounting connectivity between FY2024 sustainability statements prepared under the European Sustainability Reporting Standards (ESRS) and corresponding IFRS financial statements. Using the full eligible population of 22 Portuguese companies listed on the Euronext Lisbon regulated market, it develops and applies a 26-item Accounting Connectivity Index (ACI) across four dimensions: Referential, Quantitative, Methodological, and Accounting Consequence Connectivity. The analysis combines structured content analysis with qualitative assessment of sustainability-to-accounting pathways. ACI scores range from 17.1 to 94.8, with a population mean of 57.1. Quantitative Connectivity is the strongest and most widespread dimension, largely reflecting traceable relationships between EU Taxonomy metrics and financial-statement amounts. Accounting Consequence Connectivity, by contrast, is concentrated in seven companies. The results show that quantitative traceability does not necessarily imply substantive accounting connectivity and support a distinction between disclosure connectivity and integration into accounting assumptions, estimates, measurement, and financial-statement outcomes. Connectivity pathways also differ across sectoral and accounting contexts. The findings remain stable under alternative population definitions, item specifications, and weighting approaches. The study contributes a replicable, sector-neutral framework for evaluating the nature and depth of connectivity between sustainability and financial reporting.
