As it turns out, investing for the greater good can be profitable, too. That's the story behind the rise in environmental, social, and corporate governance (ESG) investing over the past several years. Investors are flocking to ESG investing by way of ESG-focused funds. Annually, net inflows to sustainability-focused funds from investors around the world have reached billions of dollars.

Why have ESG funds become so popular? During market contractions in 2018 and 2020, companies with solid ESG track records showed more resilience than their non-ESG peers. As a broader point of comparison, the S&P 500 ESG Index has either aligned with or outperformed the standard S&P 500 (SNPINDEX:^GSPC) over the past three-, five-, and 10-year reporting periods.
What are ESG funds?
ESG funds invest in companies that actively manage their environmental, social, and governance risks. These companies commonly pursue a range of sustainability goals, such as:
- Improving energy efficiency.
- Reducing emissions.
- Forming social advancement opportunities within their communities and workforces.
- Preventing human rights violations throughout their supply chains.
- Enforcing ethical business practices.
- Creating board independence and reporting transparency.
In short, companies that prioritize ESG are good corporate citizens. They dedicate significant resources to improving their impacts on people, communities, and the environment.
In other respects, ESG funds function like any other investment fund. When you buy shares in an ESG fund, you own a slice of the fund's holdings and participate in the fund's performance. They can be mutual funds or exchange-traded funds (ETFs).

1. iShares ESG Aware MSCI USA ETF
This ETF tracks the MSCI USA Extended ESG Focus Index. The index mimics the performance of the broader market while excluding companies involved in civilian firearms, controversial weapons, tobacco, thermal coal, and oil sands. Top holdings by value include Nvidia (NVDA -0.49%), Apple (AAPL -1.66%), and Microsoft (MSFT +0.57%).
This ETF is appropriate as an anchor position for new ESG investors who want to invest in sustainability without materially altering their risk profiles. As long as the fund meets its goal, its performance should be near that of an S&P 500 fund.
2. iShares ESG Aware MSCI EM ETF
This iShares ETF provides ESG-screened exposure to emerging markets. The fund aims to produce returns similar to unscreened emerging market indexes while prioritizing companies with higher ESG scores. The portfolio includes more than 300 large-cap and mid-cap stocks, primarily from China, Taiwan, India, South Korea, Brazil, South Africa, and Saudi Arabia.
Financial companies comprise roughly one-quarter of the fund's value, and information technology stocks are a close second. The other top three sectors are consumer discretionary, communications, and materials.
3. iShares ESG Aware U.S. Aggregate Bond ETF
The iShares aggregate ESG bond fund invests in investment-grade, dollar-denominated bonds with diversified maturities. Treasury securities comprise most of the portfolio, followed by mortgage-backed securities and corporate bonds issued by industrials, financial institutions, and utilities. The fund seeks to match the risk profile of the Bloomberg US Aggregate Bond Index while favoring issuers with higher sustainability ratings.
4. SPDR S&P 500 ESG ETF
This SPDR ETF tracks the S&P 500 ESG Index, which often outperforms the traditional S&P 500. The index excludes S&P 500 companies involved in cluster weapons, landmines, chemical weapons, nuclear weapons, tobacco, or thermal coal extraction.
Also excluded are companies that Sustainalytics has classified as noncompliant with United Nations Global Compact principles. The principles are U.N.-defined business standards covering human rights, employee rights, the environment, and anti-corruption.
This fund's top three holdings by value are Apple, Nvidia, and Microsoft. The SPDR fund weights these positions slightly higher than the iShares ESG Aware MSCI USA ETF.
5. Nuveen ESG Small-Cap ETF
Nuveen's small-cap ESG fund invests in smaller domestic companies with good ESG track records. The stocks are selected from the MSCI USA Small Cap Index, screened with exclusionary rules, and then ranked by their comparative ESG performances.

8. Invesco ESG NASDAQ 100
This equity fund is the ESG version of the popular Invesco QQQ ETF (QQQ -0.96%). The fund identifies suitable stocks from the Nasdaq-100 by screening out those participating in unsavory activities, such as tobacco and gambling. It also excludes companies that don't comply with the United Nations Global Compact principles.
The portfolio contains roughly 90 large-cap, Nasdaq-listed stocks, with Nvidia, Microsoft, and Apple at the top of the list.
