投資ファンドのネットゼロ戦略が相対的な炭素原単位(CI)指標に依存すると、実際の絶対排出削減と乖離する問題を指摘。著者らは、インフレ調整済みCI指標とポートフォリオ開始時の絶対排出制限の導入を提案。これによりオランダとスウェーデンの総排出量に相当する「排出原単位の抜け穴」を防げると論じる。
English
The paper identifies that net-zero investment strategies guided by relative carbon intensity (CI) metrics can be misleading and insufficient. It proposes an inflation-adjusted CI metric and absolute GHG emission limits at portfolio inception to close 'emission intensity loopholes' as large as the combined emissions of the Netherlands and Sweden.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、日本の機関投資家（GPIFなど）が採用するネットゼロコミットメントにも重要な示唆を与える。SSBJ開示基準では絶対排出量と原単位の両方が求められるが、実際の投資判断では原単位偏重がリスク。日本の投資家は絶対排出制限の導入を検討すべき。
In the global GX context
This paper is highly relevant to global climate finance debates, particularly for investors aligned with the Paris Agreement. It challenges the widespread reliance on carbon intensity in net-zero portfolios and offers practical solutions to align with real-world emission reductions, influencing TCFD/ISSB reporting and transition finance frameworks.
👥 読者別の含意
🔬研究者:Researchers in sustainable finance and carbon accounting will find the empirical demonstration of the 'emission intensity loophole' and the proposed metrics valuable for advancing portfolio decarbonization methodology.
🏢実務担当者:Sustainability and investment teams at asset managers and pension funds can use the paper's insights to revise their net-zero targets and reporting, moving beyond flawed intensity metrics.
🏛政策担当者:Regulators and standard-setters (e.g., ISSB, SEC, EU) can draw on this analysis to require absolute emission limits in net-zero commitments and prevent greenwashing.
📄 Abstract（原文）
ABSTRACT The climate crisis calls for rapid absolute reductions in greenhouse gas (GHG) emissions, requiring significant capital reallocation. In the financial industry, net‐zero investment strategies are mostly guided by relative carbon intensity (CI) metrics rather than absolute GHG emissions. We show that such net‐zero oriented investments can be misleading, cause insufficient investor action, and delay meaningful emission reductions. We propose two solutions: first, the rigorous and universal application of an inflation‐adjusted CI metric that accounts for changes in a key financial fundamental relative to the portfolio inception year. Second, we propose the addition of absolute GHG emission limits at portfolio inception. These measures will better align net‐zero investment strategies with real‐world absolute GHG emissions targets and avoid “emission intensity loopholes” as large as the GHG emissions of the Netherlands and Sweden together.
