ベトナムVN30の上場30社の2024年サステナビリティ報告書等を質的内容分析し、Scope 3データ測定の課題を環境管理会計(EMA)の視点で検証。多くが「ダブル・デカップリング」により象徴的な報告に留まり、環境会計と財務会計が未統合で、サプライチェーンや投融資先のScope 3データが欠如していることを示す。CBAM等の貿易障壁による競争力喪失リスクを警告し、ICPやPCAF等の高度会計ツールと柔軟な政策ロードマップを提言する。
English
This study examines Scope 3 data measurement challenges across Vietnam's 30 leading listed firms (VN30) through Environmental Management Accounting, using qualitative content analysis of 2024 sustainability and annual reports. It finds widespread "double decoupling": symbolic, communication-oriented reporting that cherry-picks data, with environmental accounting unintegrated into financial accounting and Scope 3 supply-chain and portfolio data largely absent. Warning of competitive loss under CBAM, it recommends Internal Carbon Pricing, PCAF standards, and a flexible policy roadmap to prevent greenwashing.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
新興国・輸出型企業におけるScope 3開示の実態と課題を示す事例として、SSBJ基準導入や有報でのScope 3対応、CBAM対応を迫られる日本企業・投資家にとって示唆が大きい。特にサプライチェーン上流のデータ収集難と象徴的報告(グリーンウォッシュ)リスクは、日本企業がアジア調達先を管理する際の実務的教訓となる。
In the global GX context
This adds emerging-market empirical evidence to global Scope 3 and disclosure scholarship (ISSB/CSRD/CBAM), showing how institutional pressure without technical capacity produces symbolic reporting and "double decoupling." It is directly relevant to supply-chain disclosure debates and the CBAM-driven push for credible Scope 3 accounting in export-oriented economies.

🏢実務担当者:サプライチェーン上流のScope 3データ収集と財務会計統合の難しさ、ICP・PCAF導入の実務的意義を学べる。
🏛政策担当者:CBAM等の貿易障壁を見据え、Scope 3開示義務化とEMA導入を段階的に促す柔軟な政策ロードマップ設計の必要性を示す。
📄 Abstract(原文)
This study analyzes the current situation and challenges in measuring Scope 3 emissions data across the 30 leading listed companies in the Vietnamese market (VN30) through the lens of Environmental Management Accounting (EMA). Drawing upon Institutional Theory and the Resource-Based View (RBV), the research applies qualitative content analysis to data extracted from 2024 Sustainability Reports and Annual Reports, which were coded in accordance with Gioia’s (2013) methodological framework and subjected to a rigorous inter-coder reliability testing process. Empirical results reveal the prevalence of the "Double Decoupling" phenomenon, indicating that most enterprises employ "cherry-picking" or "halo effect" techniques to construct a positive, communication-oriented image (symbolic sustainability reporting) to adapt to institutional pressures and technological deficiencies. Furthermore, environmental accounting systems lack integration with financial accounting, demonstrating a notable absence of monetized reports and Scope 3 data from supply chains and funding portfolios. Warning of the risk of losing competitive advantage amid global trade barriers such as the Carbon Border Adjustment Mechanism (CBAM), the study proposes the application of in-depth accounting tools (e.g., Internal Carbon Pricing - ICP, PCAF standards) and the establishment of a flexible policy roadmap for substantive EMA implementation, thereby preventing greenwashing risks.
