SBTi検証済み目標と韓国・豪州の開示企業について、排出量変化を産出量・エネルギー原単位・炭素強度の3項に分解し、絶対量目標の達成判定が何を覆い隠すかを検証した。産出量項を除くと検証済み目標で約4分の1、開示企業で3〜4割の判定が変わる。成長企業年の半数〜3分の2では産出量当たり排出は低下しており、判定は総量には正確だが構成には沈黙する。新規データなしで各判定を3項で開示できると提案する。
English
Decomposing emissions change into output, energy intensity and carbon intensity terms, this paper re-evaluates SBTi-validated targets and Korean/Australian disclosing firms. Removing the output term flips roughly one in four validated-target verdicts and three to four in ten disclosing-firm verdicts. Half to two-thirds of growing firm-years with rising emissions still cut emissions per unit of output. Verdicts are accurate on totals but silent on composition; reporting all three terms needs no new data.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準・有報でのScope1/2開示が進む日本企業にとって、絶対量目標の達成判定だけでは移行経路の実態（効率改善か縮小か）を示せないという論点は、統合報告書での説明責任や投資家との対話に直結する。SBTi認証取得企業が多い日本では、目標判定の構成分解を開示に加える実務的示唆が大きい。
In the global GX context
As ISSB/SSBJ-aligned disclosure and CSRD push firms toward transition-plan reporting, this paper argues that absolute-target verdicts alone misrepresent the route taken. It offers a no-new-data decomposition that lenders and assurance providers can use to test whether efficiency, fuel switching or asset retirement carried a verdict — directly relevant to transition-finance eligibility and greenwashing scrutiny.
👥 読者別の含意
🔬研究者:絶対量目標の達成判定を要因分解する手法を、SBTi検証データと開示データに適用した実証枠組みを提供する。
🏢実務担当者:自社の目標達成が効率改善によるものか縮小によるものかを3項で説明でき、移行計画の説得力を高められる。

📄 Abstract（原文）
Transition finance supports high-emitting firms along different routes, from efficiency and fuel switching to retiring high-emitting assets. Yet progress is often judged by whether a firm meets an absolute emissions target. We ask what this verdict shows about how its result arose. A firm's emissions change sums the changes in its output, energy use per unit of output and emissions per unit of energy. We recompute each verdict with the output term removed and, without price data, with the change in energy use removed. We apply both to targets validated by the Science Based Targets initiative and, imposing a 1.5°C-aligned path, to the firms in Korean and Australian disclosures and sustainability reports. The verdict is accurate about total emissions but silent about their composition. Growing firm-years with rising emissions miss a one-year path by construction, yet in half to two-thirds of them emissions per unit of output fell. Removing output changes about one verdict in four under validated targets and three to four in ten among disclosing firms with revenue. In Korea the total follows output through energy use, while emissions per unit of energy show little association with sales. Attainment with lower output is not thereby undeserved, as it may reflect a planned retirement; the decomposition cannot establish which route a firm is on. It shows which component carried a verdict and so which evidence, such as retirement plans or equipment and fuel changes, a lender should check. Reporting each verdict with its three terms requires no new data. Preprint, not peer reviewed. Version 1, 2 October 2026.
