Can you make money while making a difference? ESG investing suggests the answer is yes. By integrating environmental, social, and governance criteria into investment decisions, ESG investors aim to build portfolios that reflect their values while maintaining competitive financial returns.
What Does ESG Stand For?
Environmental (E)
How a company manages its relationship with the natural environment:
- Carbon emissions and climate change strategy
- Energy efficiency and renewable energy usage
- Water usage and waste management
- Biodiversity impact and deforestation
- Pollution control and environmental compliance
Social (S)
How a company manages relationships with employees, suppliers, customers, and communities:
- Labor practices, worker safety, and fair wages
- Diversity, equity, and inclusion
- Supply chain ethics and human rights
- Community relations and social impact
- Data privacy and consumer protection
Governance (G)
How a company is led and controlled:
- Board composition, independence, and diversity
- Executive compensation alignment with shareholders
- Shareholder rights and anti-takeover provisions
- Anti-corruption policies and business ethics
- Transparency and accounting standards
Approaches to ESG Investing
Negative Screening (Exclusions)
Excluding industries or companies that do not meet certain standards: weapons, tobacco, gambling, fossil fuels, adult entertainment. The simplest ESG approach — you define what you will not own.
Positive Screening (Best-in-Class)
Selecting companies that rate highest on ESG metrics within each sector. Rather than excluding an entire sector, you choose the oil company with the best environmental practices, for example. This maintains sector diversification while rewarding leaders.
ESG Integration
Incorporating ESG factors into traditional financial analysis without necessarily excluding any sectors. ESG risks (regulatory fines, reputational damage, supply chain disruptions) are financially material and should inform valuations and risk assessments.
Impact Investing
Investing specifically to generate measurable positive social or environmental impact, alongside financial returns. Common in green bonds, social bonds, and private equity investments in clean technology or sustainable agriculture.
Shareholder Engagement
Using the rights of ownership to push companies toward better ESG practices through voting at shareholder meetings and engaging with management. Practiced by major asset managers like BlackRock and Norges Bank.
Does ESG Investing Sacrifice Returns?
This is the central question for pragmatic investors. The evidence is nuanced but encouraging:
- Multiple meta-analyses of ESG research find that ESG integration has either neutral or mildly positive effects on returns
- ESG ETFs tracking MSCI World ESG indices have broadly matched or slightly outperformed the parent index over the past decade
- Companies with strong governance (the G in ESG) consistently show lower cost of capital and better risk management
- Climate-related risks are increasingly recognized as financially material, suggesting better-prepared companies will face fewer future shocks
However, ESG is not a performance guarantee. The 2022 energy rally significantly benefited fossil fuel stocks that ESG funds excluded. Short-term periods of ESG underperformance should be expected.
ESG Ratings: What You Need to Know
ESG ratings from agencies like MSCI, Sustainalytics, and S&P differ significantly in their methodologies. The same company can receive an A from one rater and a C from another. This inconsistency is a known limitation of the ESG ecosystem and reflects genuine complexity in measuring non-financial factors.
Look beyond a single rating. Understand what criteria the rating uses and whether they align with your specific values.
Getting Started with ESG Investing
- Define your values — which issues matter most to you? Climate? Labor rights? Weapons?
- Research ESG ETFs that screen for your priorities (MSCI World ESG Enhanced, iShares Paris-Aligned Climate ETFs, Xtrackers ESG ETFs)
- Compare the ESG ETF’s performance and holdings to its conventional counterpart
- Check expense ratios — ESG ETFs have become competitive in cost, often matching conventional indices at 0.12-0.20% TER
- Consider your pension provider — push for ESG options in your pension scheme
ESG investing is not perfect, and no investment can claim to be entirely “ethical” in every dimension. But for investors who want their capital to reflect their values while participating in market returns, ESG provides a practical and increasingly sophisticated toolkit.
