ナイジェリアと南アフリカの上場企業2015〜2024年のパネルデータを用い、グリーンウォッシュの要因とステークホルダー信頼への影響を比較分析した。ナイジェリア企業でグリーンウォッシュがより多く、南アフリカ企業はガバナンスとESG開示の信頼性が高い。グリーンウォッシュはステークホルダー信頼には有意に影響しないが、ESG開示の信頼性を有意に低下させる。取締役会独立性や監査委員会規模の効果は両国で対照的であり、規制執行強化と独立したESG保証を提言する。
English
Using panel data from listed firms in Nigeria and South Africa (2015–2024), this study compares drivers of greenwashing and its effects on stakeholder trust and ESG disclosure credibility. Greenwashing is more prevalent in Nigeria, while South African firms show stronger governance and more credible disclosures. Greenwashing significantly reduces ESG disclosure credibility but not stakeholder trust, and governance effects differ across countries. The authors recommend stronger governance, regulatory enforcement, and independent ESG assurance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準の導入と有報でのサステナビリティ開示が進む中、開示の信頼性を担保するガバナンスと第三者保証の重要性を示す。新興国比較は、日本企業のグローバル・サプライチェーンにおけるESGデューデリジェンス強化の根拠となり得る。
In the global GX context
As ISSB/IFRS S1-S2 adoption spreads globally, this paper provides emerging-market evidence that governance mechanisms and assurance are critical to disclosure credibility. It complements TCFD/CSRD debates by showing that greenwashing undermines credibility more than stakeholder trust, with implications for regulatory enforcement and independent assurance requirements.
👥 読者別の含意
🔬研究者:Provides comparative panel evidence on greenwashing determinants and the mediating role of trust in emerging African markets, useful for testing disclosure-credibility frameworks.
🏢実務担当者:Highlights the need for robust governance and independent ESG assurance to avoid greenwashing accusations and maintain disclosure credibility, especially in weak-governance contexts.
🏛政策担当者:Supports stronger regulatory enforcement and mandatory independent ESG assurance, particularly in Nigeria, to improve disclosure quality and stakeholder confidence.
📄 Abstract（原文）
The growing adoption of ESG reporting among listed companies in Nigeria and South Africa has raised concerns about greenwashing, weak corporate governance, and the credibility of sustainability disclosures. This study examines the factors influencing greenwashing, its effect on stakeholder trust, the mediating role of stakeholder trust in ESG disclosure credibility, and the influence of corporate governance mechanisms. Using an ex post facto comparative panel research design, the study analysed data from selected listed companies over the period 2015-2024, employing descriptive statistics, correlation analysis, panel unit-root tests, fixed- and random-effects regressions, Hausman specification tests, mediation analysis, and robustness tests. The findings indicate that greenwashing is more prevalent among Nigerian firms, while South African firms demonstrate stronger governance structures and more credible ESG disclosures. Corporate governance mechanisms significantly influence greenwashing, with board independence and audit committee size reducing greenwashing in South Africa but exhibiting contrasting effects in Nigeria. Greenwashing does not significantly affect stakeholder trust in either country but significantly reduces ESG disclosure credibility. Furthermore, stakeholder trust does not significantly mediate the relationship between greenwashing and ESG disclosure credibility. The study recommends stronger corporate governance mechanisms, enhanced regulatory enforcement, independent ESG assurance, and transparent and verifiable sustainability reporting, particularly in Nigeria, to curb greenwashing and strengthen the credibility of ESG disclosures.
