ESG Credibility, Ratings, and Greenwashing: Key Concepts and Challenges

1. Importance of ESG Ratings

  • ESG scores, climate rankings, and sustainability indices help investors, regulators, and consumers evaluate corporate sustainability performance.
  • Ratings differentiate between companies that are performing vs. pretending.

2. How ESG Ratings Work

  • Agencies like MSCI, Sustainalytics, Refinitiv, and ISS rate companies based on risk management across environmental, social, and governance (ESG) criteria.
  • Challenges:
    • Different agencies use different indicators, weights, and data sources.
    • Reliance on self-reported data rather than verified audits.
    • Scores often reflect disclosure quality, not actual performance.

Example: Inconsistent Ratings

Company Environmental Score Social/Governance Score Reason
Tesla High Low Labor and transparency issues
ExxonMobil Lower actual impact Higher ESG score Strong disclosure systems, but not necessarily cleaner operations

3. The Greenwashing Problem

Greenwashing refers to companies appearing sustainable without making meaningful changes.

Common Tactics:

  • Highlighting minor achievements while hiding larger negative impacts.
  • Using vague, eco-friendly language without supporting data.
  • Publishing glossy reports while continuing harmful practices.

Quote: “Sustainability reporting is often used as a substitute for sustainability performance.” – Parker

4. Efforts to Improve Credibility

  • Regulatory Push: EU Taxonomy, CSRD (Corporate Sustainability Reporting Directive).
  • India: SEBI BRSR Core with sector-specific KPIs and third-party assurance.
  • Global Frameworks: IFRS, ISSB for standardization.
  • New Approaches: Impact-based metrics, supply chain audits.

5. Key Challenges

  • Too many standards, too little enforcement.
  • ESG space described as a “wild west”.
  • Ratings are helpful only when paired with:
    • Strong verification
    • Transparency
    • Regulation

6. The Ultimate Goal

Not just to look green, but to act green across operations, products, and people.

📘 Exam Tip:

Focus on understanding the difference between disclosure-based ratings and actual performance. Be prepared to explain greenwashing with examples, and know how regulatory frameworks like CSRD and BRSR aim to improve credibility. Use comparative examples (e.g., Tesla vs. ExxonMobil) to illustrate rating inconsistencies.
