本研究は、SBTiへの参加が企業の炭素パフォーマンスに与える影響をScope1,2,3に分けて分析。2015〜2024年の欧米アジアの上場企業3113社を対象に、傾向スコアマッチングとOLS回帰を用いた結果、Scope1と市場ベースのScope2で改善が見られたが、立地ベースのScope2とScope3では有意な効果は観測されなかった。
English
This study examines whether SBTi participation improves corporate carbon performance across emission scopes. Using coarsened exact matching and OLS regression on 3,113 listed firms (2015-2024) in Europe, North America, and Asia, it finds consistent improvements in Scope 1 and market-based Scope 2, but no effects on location-based Scope 2 or Scope 3. Results suggest SBTi signals credible direct emission reductions, but stronger guidance is needed for Scope 3.

日本のGX文脈において
本論文はSBTiの効果をScope別に検証しており、日本企業のSBT認証取得やSSBJでのScope3開示に関する議論に示唆を与える。特にScope3での改善が見られない点は、日本のサプライチェーン排出削減政策の課題と重なる。
In the global GX context
This paper provides empirical evidence on SBTi effectiveness across emission scopes, relevant to global disclosure frameworks like TCFD and ISSB. The null result on Scope 3 highlights a critical gap in current target-setting approaches, informing ongoing debates on Scope 3 accountability in CSRD and SEC climate rules.
👥 読者別の含意
🔬研究者:Provides rigorous causal evidence on SBTi's differential impact across scopes, offering a benchmark for future research on corporate climate target credibility.
🏢実務担当者:Suggests that while SBTi signals genuine progress on direct emissions, companies should not assume it drives Scope 3 reductions without additional supply chain engagement.
🏛政策担当者:Indicates a need for stronger regulatory guidance on Scope 3 target setting and verification, aligning with ISSB and CSRD developments.
📄 Abstract（原文）
Abstract Corporate climate strategies increasingly rely on science-based targets to demonstrate credible alignment with global decarbonization pathways. This study examines whether participation in the Science-Based Targets initiative (SBTi) is associated with measurable improvements in corporate carbon performance by disentangling effects across Scope 1, Scope 2 (both location- and market-based), and Scope 3. After applying coarsened exact matching, the analysis covers 3113 listed firms in Europe, North America, and Asia between 2015 and 2024, tracking outcomes for up to four years post-participation and estimating effects using ordinary least squares regression. The results show consistent improvements in Scope 1 and market-based Scope 2, while no measurable effects are observed for location-based Scope 2 and Scope 3. Robustness checks, including alternative dependent variables for corporate carbon performance and a stacked difference-in-differences analysis, corroborate these findings. Overall, the findings suggest that the SBTi serves as a quality signal of credible corporate efforts to reduce directly controllable emissions. At the same time, fostering progress on Scope 3 demands stronger guidance and enhanced monitoring. The results also highlight promising avenues for future research on cross-scope interactions and the long-term dynamics of Scope 3 reductions.
