More people than ever are asking not just “How much can I earn from this investment?” but also, “What kind of impact does this investment have on the world?” That question lies at the heart of ESG investing—a fast-growing approach to building wealth while staying true to your values.
Whether it’s climate change, social justice, or ethical corporate governance, ESG investing aims to reward companies that are doing better for people and the planet. But is it right for you? And can it deliver competitive returns?
This guide breaks down what ESG investing is, how it works, the pros and cons, and whether it makes sense for your portfolio.

Environmental (E)
-
Climate change policies
-
Carbon footprint
-
Water usage
-
Renewable energy efforts
-
Pollution controls

What Is ESG Investing?
ESG investing is the strategy of selecting investments—typically stocks, ETFs, or mutual funds—based on how companies perform on environmental, social, and governance criteria.
The idea is to invest in businesses that:
-
Minimize environmental harm
-
Treat employees and communities fairly
-
Are well-managed and transparent
ESG investing may involve:
-
Positive screening: Investing in high-scoring ESG companies
-
Negative screening: Avoiding certain industries like tobacco, oil, or weapons
-
Thematic investing: Focusing on sectors like clean energy or sustainable agriculture
-
Shareholder activism: Using investment power to influence company behavior
How Is ESG Scored?
Several firms—including MSCI, Sustainalytics, and Morningstar—analyze companies and assign ESG scores based on available data and disclosures. These scores are often used by ESG-focused funds to build portfolios.
However, ESG scoring isn’t standardized. One firm might rate a company highly while another might not, based on different metrics or data interpretations.
How to Invest in ESG
1. ESG Mutual Funds and ETFs
These funds bundle dozens or hundreds of ESG-rated companies into a single investment. They offer instant diversification and professional screening.
Popular options include:
-
iShares ESG Aware MSCI USA ETF (ESGU)
-
Vanguard ESG U.S. Stock ETF (ESGV)
-
SPDR S&P 500 ESG ETF (EFIV)
-
Parnassus Core Equity Fund (PRBLX)
You can find ESG funds that track broad markets or specific sectors like tech, energy, or international stocks.
2. Robo-Advisors With ESG Options
Platforms like Betterment, Wealthfront, and Ellevest offer ESG portfolios. You simply select ESG as a preference, and they do the rest—automatic deposits, rebalancing, tax-loss harvesting, etc.
3. Self-Directed ESG Portfolios
If you want control, you can research and pick individual ESG-rated stocks yourself. Use tools like:
-
MSCI ESG Ratings
-
Yahoo Finance ESG tab
-
Morningstar Sustainability Ratings
Just be aware that building a balanced portfolio manually requires more time and risk management.
Does ESG Investing Hurt Returns?
This is one of the most common concerns—and the research may surprise you.
The Evidence:
-
Multiple studies show that ESG investments perform as well or better than non-ESG portfolios over time.
-
ESG companies often manage risk better, avoid scandals, and have more loyal customers and employees.
-
ESG funds may be slightly more expensive (higher fees), but many now offer low-cost index-style options.
The Catch:
-
In short timeframes, ESG can underperform if fossil fuels or controversial industries (like defense or gambling) are booming.
-
ESG screens may reduce diversification if too many companies are excluded.
Pros of ESG Investing
1. Aligns Your Money With Your Values
You’re supporting businesses that prioritize sustainability, fairness, and ethics—without having to give up investing.
2. May Lower Long-Term Risk
Companies with poor ESG practices often face legal, regulatory, or reputational trouble that affects stock prices.
3. Access to a Growing Market
Demand for ESG transparency is rising. ESG investing is expected to reach over $50 trillion globally by 2025.
4. Diversification Without Complexity
Most ESG funds still include hundreds of companies across sectors. You’re not sacrificing diversification.
Cons of ESG Investing
1. Lack of Standardization
ESG ratings vary widely between providers. It’s not always clear how companies are scored—or why.
2. Greenwashing
Some companies talk the ESG talk but don’t walk the walk. Without deep research, you might unknowingly invest in a firm with poor actual practices.
3. Higher Fees (Sometimes)
Some actively managed ESG funds charge higher expense ratios. But low-cost ESG index ETFs are increasingly available.
4. Possible Underperformance in Certain Markets
If excluded industries (like oil) are outperforming, ESG funds may lag temporarily.
ESG vs SRI vs Impact Investing
These terms are often used interchangeably but have subtle differences:
-
ESG Investing: Focuses on incorporating ESG scores to enhance financial performance and reduce risk
-
SRI (Socially Responsible Investing): More values-based; excludes “sin stocks” or companies that violate specific moral criteria
-
Impact Investing: Seeks direct social or environmental outcomes (e.g., investing in microfinance or solar energy projects)
ESG investing is often the most balanced between profit and principle.
FAQs About ESG Investing
Is ESG investing only for liberals or environmentalists?
No. ESG investing appeals to a wide range of people—anyone who wants their investments to reflect their values or avoid long-term risks.
Do ESG funds include tech stocks?
Yes. Many tech giants like Apple, Microsoft, and Nvidia score well on ESG criteria and are widely held in ESG funds.
Can I invest in ESG through my 401(k)?
Possibly. Some employers now offer ESG funds in their retirement plan lineup. If not, consider using an IRA or taxable account for ESG investments.
How can I tell if a fund is truly ESG?
Look at the fund’s holdings, ESG methodology, and whether it’s screened, actively managed, or passively following an ESG index.
Can ESG investing help fight climate change?
Yes—indirectly. By channeling capital away from high-emission companies and toward green alternatives, investors can help shift corporate behavior over time.
Final Thoughts: Values and Returns Don’t Have to Be Opposites
You don’t have to choose between growing your wealth and doing good in the world. ESG investing allows you to build a portfolio that reflects your values while potentially reducing risk and accessing long-term growth.
If you care about sustainability, ethics, and governance—and want to invest with purpose—ESG offers a path that’s both practical and principled.
It’s not about being perfect. It’s about being intentional.
