企業の気候移行評価指標として「Budget-at-Risk」を提案し、概念的・実証的に検証した研究。FTの「Europe's Climate Leaders」ランキングを事例に、データ検証の不足や排出原単位など変動性の高い指標への過度な依存が企業の実際の排出動向を覆い隠すことを示す。累積排出量やセクター別脱炭素経路、秩序ある気候シナリオ下での削減要件を欠くランキングは誤解を招く結果を生みうると指摘する。
English
This study proposes and validates Budget-at-Risk, a forward-looking metric quantifying a firm's emissions surplus or deficit against a sectoral carbon budget at a given confidence level. Using the FT's 'Europe's Climate Leaders' ranking as a case, it shows that weak data verification and overreliance on volatile metrics like emissions intensity can mask real emissions dynamics. Omitting cumulative emissions, sectoral decarbonization pathways, and orderly-scenario reduction requirements may yield misleading rankings.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準や有報での気候関連開示が進む日本では、企業評価・ランキング手法の妥当性検証は投資家対応や移行金融の判断材料として重要。第三者評価の限界を理解する上で示唆に富む。
In the global GX context
As ISSB/CSRD and transition-finance frameworks mature, this paper directly critiques how third-party transition rankings are constructed, offering regulators and standard-setters a methodology to stress-test disclosure-based assessments against sectoral carbon budgets.

🏛政策担当者:移行評価・ランキング制度の設計時に、累積排出量やセクター経路の組み込みを検討すべき根拠となる。
📄 Abstract（原文）
As corporate climate commitments become increasingly widespread, the need for robust assessment methodologies to evaluate progress towards their achievement is imperative. However, the development of such methodologies requires careful consideration of several critical factors and potential pitfalls. We use Budget-at-Risk as a forward-looking transition assessment metric that quantifies a firm’s emissions surplus or deficit relative to a targeted sectoral budget at a specified confidence level. We evaluate Budget-at-Risk through a combination of conceptual and empirical validation analyses and compare the resulting assessments with the annual “Europe’s Climate Leaders” ranking published by the Financial Times. Taking “Europe’s Climate Leaders” ranking as an illustrative example, we show that inadequate data verification and an overreliance on volatile metrics such as emissions intensity may mask the real emissions dynamics of firms. Moreover, the exclusion of critical transition dimensions, including cumulative emissions, sector-specific decarbonisation pathways and the emissions reductions required under orderly climate scenarios, might produce misleading and controversial ranking outcomes. Our study is particularly relevant to policymakers and regulators, who develop transition assessment methodologies, as well as to stakeholders whose decisions rely on such ranking results.
