ESG investing means considering environmental, social, and governance factors alongside traditional financial analysis. It’s grown from a niche approach to a major force in global markets.
What ESG Actually Means
| Factor | What It Measures | Examples |
|---|
| Environmental | Impact on the planet | Carbon emissions, pollution, renewable energy |
| Social | Impact on people | Labour standards, diversity, community relations |
| Governance | How the company is run | Board diversity, executive pay, shareholder rights |
ESG Investing Approaches
| Approach | Strategy | Example |
|---|
| Exclusionary | Avoid “sin stocks” (tobacco, weapons, fossil fuels) | Most basic ESG funds |
| Best-in-class | Invest in leaders within each sector | Companies with highest ESG ratings |
| Thematic | Invest in specific ESG themes | Clean energy, water, gender equality |
| Impact | Measurable positive outcomes | Green bonds, community development |
| Integration | ESG factors into standard analysis | Sophisticated institutional approach |
This is the most debated question in ESG investing.
| Period | ESG vs Non-ESG | Notes |
|---|
| 2010–2019 | ESG slightly ahead | Low rates favoured ESG companies |
| 2020–2021 | ESG significantly ahead | Tech and clean energy boomed |
| 2022 | ESG underperformed | Energy stocks (low ESG) soared |
| 2023–2026 | Roughly equal | Performance has converged |
Conclusion: ESG doesn’t inherently underperform. But it does have sector biases — less energy, more tech — which affect relative performance in different market conditions.

How to Evaluate ESG Funds
| Question | What to Check |
|---|
| What’s excluded? | Oil, tobacco, weapons, gambling? |
| How is ESG scored? | In-house, MSCI, Sustainalytics? |
| Does it match your values? | Some “ESG” funds still hold fossil fuels |
| What’s the track record? | At least 3 years of performance |
| What’s the fee? | ESG funds tend to have higher fees |
Common Criticisms
- Greenwashing — Some funds claim ESG credentials without meaningful screens
- Inconsistent ratings — MSCI, Sustainalytics, and S&P often rate the same company differently
- Lower diversification — Exclusion reduces your investment universe
- Not always ethical — A “best-in-class” oil company is still an oil company
ESG in 2026: Current Trends
- EU Sustainable Finance Disclosure Regulation (SFDR) — Article 8 and 9 fund classifications

Bottom Line
ESG investing allows you to align your portfolio with your values without necessarily sacrificing returns. Choose a fund with transparent criteria and a strong track record. Beware of greenwashing — read the fund’s holdings, not just its marketing. And remember: the best ESG investment is one you can stick with through market cycles.
