In the past decade, ESG (environmental, social, governance) became a buzzword in investment circles for good reason. An ESG ETF is an exchange-traded fund that invests in companies that adhere to certain environmental, social, and governance (ESG) criteria.
Many investors have flocked to ESG ETFs over the years. Proponents have argued that ESG investing isn't just about caring for people and the planet; it's also good business, as some research suggests that companies with high ESG values have shown.
But ESG investing seems to have fallen out of favor with many investors, particularly in the U.S. Morningstar reports that U.S. investors withdrew about $6.1 billion from ESG and sustainable ETFs in 2024.
Declining enthusiasm about ESG ETFs has been attributed to a number of factors, including political backlash, high interest rates, poor performance, and concerns about greenwashing. Still, if you're a long-term investor who cares about mitigating risk and choosing investments that align with your values, ESG ETFs could be worth considering.
Exchange-traded funds, or ETFs, are collections of stocks or bonds. Some ETFs invest in securities that focus on certain themes. ESG ETFs are ETFs that invest in stocks or bonds based on environmental, social, and governance criteria. Sometimes, they're referred to as sustainable funds.
There are a few approaches to constructing an ESG ETF, including:
- Negative screening: Many ESG ETFs use a benchmark index that tracks a specific segment of the stock market, like the S&P 500 index, but exclude companies that have controversial practices or products, i.e., tobacco or fossil fuel companies.
- Positive or best-in-class screening: An ESG ETF may invest specifically in companies that receive above-average ESG scores compared to their peers.
- Thematic investing: Some ESG ETFs invest in specific themes, like clean energy, gender equality, or sustainable water.
- ESG integration: Some ETFs consider ESG factors in constructing a portfolio alongside other traditional financial criteria, like performance and risk, without specifically including or excluding companies based specifically on ESG benchmarks.
Before investing in any ETF, whether an ESG ETF or another type of fund, investors should consider factors like its historical performance, ETF expense ratio, dividend payments, and holdings before buying shares.
