It’s an attractive proposition: Generate financial returns while backing companies committed to developing environmentally sustainable technologies, products, and services. Rather than relying solely on government policy or personal consumption habits to fight climate change, they let their money and the power of the markets go to work.
While often grouped under environmental, social, and governance (ESG) framework, green investing—also called eco-investing or sustainable investing—is focused on environmental sustainability, especially producing clean energy and reducing carbon emissions. Below, we take you through how exchange-traded funds (ETFs) are acting as a conduit for green investing.
Key Takeaways
- While environmental, social, and governance (ESG) investing includes an environmental component, green investing focuses on it: clean energy, sustainable infrastructure, and reducing carbon emissions.
- Green ETFs offer investors the chance to diversify while investing in sustainability and avoiding single-company risk in emerging sectors.
- While long-term returns for renewables-focused companies remain promising, investors are likely to face periodic volatility due to shifting political winds in the U.S.
- Beware of greenwashing if you’re committed to the fight against climate change. Some funds exaggerate the environmental credentials of the companies they’re invested in.
What Are Green ETFs?
Green ETFs let investors take on climate change by investing in companies engaged in that fight, whether by producing solar power and battery storage or developing green buildings. This investment is critical. According to one estimate, investment in renewable energy needs to triple during the 2020s if the world is to fight climate change effectively.
As the climate crisis worsens, the number of green ETFs has risen, but so too have claims of “greenwashing” by funds looking to attract money with exaggerated claims. Regulators have tried to clamp down on such practices, but investors still need to conduct due diligence to be sure they’re investing in the right ETFs. They also need to be aware of higher levels of volatility that can come with investing in industries that can be heavily affected by policy.
While some green ETFs track broad ESG indexes that lean toward environmental impact, most focus on environmental impact, offering an accessible way for institutions and individuals to align their portfolios with their environmental goals. The advantage of doing so via ETFs is that investors don’t have to research individual stocks or worry about picking winners and losers in emerging industries. They can immediately achieve diversification while enjoying the convenience and cost-effectiveness of buying and selling green ETFs on traditional exchanges.
As with ETFs in general, some green ETFs are more narrowly focused than others. You might invest in a broad range of companies across multiple sectors, or concentrate in “pure” play sectors—a handful of solar or wind-power companies, for example. Those that are more narrowly focused can be especially sensitive to any change in government policy because many rely on the support of government initiatives or carbon-emission regulations. That’s been the case in the mid-2020s, with cuts from the current administration.
Note
A survey of fund managers found that more than 60% say that companies that perform poorly on environmental or social issues metrics will lag behind companies that don’t.
Returns and Volatility
The idea that sustainable investing comes with weaker returns is increasingly being called into question. While green investing may underperform when other sectors are booming—think oil and gas immediately after the Russian invasion of Ukraine—the growing consensus among fund managers is that performance on environmental and social issues is linked with financial outcomes. In one survey, 67% of managers of sustainable funds and 61% of traditional fund managers said companies that perform poorly on environmental or social issues will lag companies that don’t.
But that doesn’t mean green investing won’t be a bumpy ride, especially in the short term. After several years of huge inflows, since 2022 many green funds have seen sharp declines in value as well as massive outflows. Several factors have driven these results. Higher interest rates have made financing clean energy projects more expensive, supply chain issues have slowed development, and inflation has pushed up costs. Some sectors, especially solar, have also struggled with overproduction.
Politics is also a risk. Much of the gains seen in the early 2020s were driven by green-friendly policies from the Biden administration. Some of these were canceled during the beginning of Donald Trump’s second term, which contributed to a wave of outflows from renewable-focused ETFs. The largest clean energy funds, including iShares Global Clean Energy ETF (ICLN) and Invesco Solar ETF (TAN), experienced sharp losses following the election.
Still, some analysts view the recent downturn as a mere correction from the days of peak ESG enthusiasm. They say rising capital costs could be a temporary setback rather than a long-term deterrent, and point to broad support for the clean energy transition both worldwide and among a significant share of Americans. The expectation is that the long-term growth trajectory remains intact, despite the mid-2020s bearishness.
‘Greenwashing’
With interest in sustainability investing surging, some fund managers have engaged in “greenwashing,” making false or exaggerated claims about the environmental merits of their funds, undermining both investor trust and the broader fight against climate change.
Regulators are beginning to crack down. In one high-profile case, New York-based WisdomTree agreed to pay $4 million to settle charges by the U.S. Securities and Exchange Commission (SEC) that three ETFs it had labeled as ESG had later invested in coal mining and natural gas extraction.
In another case, fund manager DWS Investments, which is controlled by Deutsche Bank (DB), agreed to pay $25 million to settle allegations that it overstated the ESG characteristics of its funds and violated anti-money-laundering rules.
To fight this, the SEC amended its “Names Rule” in 2023, requiring funds to invest at least 80% of their assets in line with the themes suggested by their names, including ESG strategies. Still, investors should carefully examine the holdings of any green ETF to make sure they’re getting into the kind of investments they’re promised.
Warning
While regulators are cracking down on “greenwashing,” investors who are committed to the fight against climate change should still scrutinize the holdings of any green ETF they’re considering.
Evaluating Green ETFs
There are several steps investors can take to verify a green ETF‘s environmental credentials.
- Read the fund’s prospectus. It will outline the stated investment strategy and objectives, including the criteria for selecting companies. Does it rely on proprietary analysis or widely accepted third-party screening systems? Does it use exclusionary screening—merely avoiding companies that don’t meet sustainability standards—or does it focus on “pure play” companies in green sectors?
- Look at the fund’s actual holdings. Make sure the holdings align with your values. Do you see companies that you personally consider objectionable for environmental reasons?
- Look at third-party certifications. A stamp of approval from organizations like Fairtrade, BioGro Organic, and B Corp lends credibility to the fund’s claim to green status. Compare how these different groups rate the fund and their criteria for doing so.
- Ask questions. Don’t be afraid to contact the fund provider and ask detailed questions about their holdings and how they select them.
The Bottom Line
Green ETFs offer an accessible, potentially impactful way for the average investor to support the battle against climate change while pursuing meaningful financial returns. But they come with their own risks, including greenwashing and policy-induced volatility, so it’s essential for all investors to do their homework.
