本研究は、化石燃料企業10社と新エネルギー企業34社のESG開示品質を、内容分析を用いて比較。新エネルギー企業は採用フレームワーク数が多く、MSCI格付け上位到達率が高く、Scope 3を含むカーボンニュートラル宣言が多い一方、伝統企業は格付け改善速度が速く、全社が取締役会レベルのESG委員会を設置。開示の広さが必ずしも実質的なパフォーマンス向上を意味しないと論じる。

English

This study compares ESG disclosure quality between 10 traditional energy and 34 new energy companies using content analysis. New energy firms adopt more frameworks, achieve higher MSCI ratings, and include Scope 3 in net-zero commitments more often, while traditional firms improved ratings faster and all have board-level ESG committees. The authors argue broader disclosure does not necessarily indicate better performance.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではSSBJ開示が始まり、エネルギー企業の開示品質比較は投資家対応に示唆を与える。特にScope 3を含むカーボンニュートラル宣言の実態把握は、日本のエネルギー企業の開示戦略に参考になる。

In the global GX context

Globally, this paper contributes to the debate on disclosure quality vs. actual performance, relevant to ISSB and CSRD implementation. It highlights that framework adoption and ratings may not reflect true sustainability outcomes, informing standard-setters and investors.

👥 読者別の含意

🔬研究者:Provides empirical evidence on ESG disclosure quality differences between energy sectors, useful for studies on greenwashing and disclosure effectiveness.

🏢実務担当者:Highlights that adopting more frameworks and achieving high ratings may not equate to better performance; encourages focus on substantive metrics.

🏛政策担当者:Suggests that disclosure regulations should emphasize outcome-based indicators rather than just framework adoption.

📄 Abstract（原文）

Today, almost all major energy companies publish information about their Environmental, Social, and Governance (ESG) practices. However, it remains unclear whether there is a real difference in the quality of these documents between companies selling fossil fuels and those selling clean technologies. This study uses a transparent and repeatable content analysis method to compare the ESG disclosure quality of 10 traditional energy companies and 34 new energy companies. This study compares each company along four dimensions: the number and types of reporting frameworks adopted, changes in MSCI ESG ratings from 2023 to 2025, the format of key sustainability forms, and a small number of outcome indicators such as total greenhouse gas emissions and board gender. Descriptive results indicate that new energy companies adopt a broader portfolio of frameworks (61.8% use three or more frameworks, compared to 40.0% for traditional companies), are more likely to reach MSCI top-tier levels (33.3% vs. 0.0% in 2025), and more likely to include Scope 3 emissions in their carbon neutrality commitments (70.6% vs. 10.0%). However, the study also finds that traditional companies improved their average MSCI scores faster over three years, and all 10 companies had ESG committees at the board level. The study therefore argues that broader disclosure shouldn't be read as proof of genuinely better performance.
