ESG investing is no longer niche—it’s mainstream. But evaluating a company’s ESG performance can be complex, especially when public perception plays such a large role. That’s where sentiment analysis adds value.
By analyzing how companies are discussed in trusted media, NGO reports, and regulatory sources, sentiment analysis reveals real-time insights into how stakeholders perceive a company’s environmental, social, and governance performance.
Why Sentiment Matters in ESG
- ESG ratings are lagging
Most ESG scores are updated quarterly or annually. Sentiment updates daily—or hourly. - Perception affects capital flow
A company’s inclusion in ESG funds can depend on how it’s perceived in public discourse. - Trust is intangible but measurable
Sentiment makes brand trust and stakeholder confidence visible and trackable.
How Sentiment Works Across ESG Pillars
| Pillar | Sentiment Insight |
|---|---|
| Environment | Track media tone around emissions, sustainability claims, or pollution incidents. |
| Social | Monitor sentiment related to labor practices, diversity, and human rights. |
| Governance | Capture tone around leadership ethics, transparency, and board decisions. |
Use Cases in ESG Investing
- Build portfolios that reflect both performance and perception
- Identify greenwashing risks through controversy sentiment
- Track stakeholder trust over time
- Align reporting with public sentiment trends
Challenges and Considerations
- Not all coverage is equally reliable—source weighting matters
- Sentiment scores must be calibrated for financial and ESG contexts
- False positives can occur during polarized public debates
