What could climate change mean for your investments?

Long-term growth forecasts are at risk, says our Chief Investment Office. Consider these three approaches to investing in a cleaner world as you build your portfolio.


September 17, 2021


Solar thermal power plants, like the massive one in California’s Mojave Desert pictured in the photo above, have very low greenhouse gas emissions.

THE EFFECTS OF CLIMATE CHANGE on the environment are well known. Increasingly, though, there’s recognition of its potential financial impact on the global economy and, by extension, on corporations and the markets. Without a sharp reduction in carbon emissions, temperatures could rise to 3 degrees Celsius above preindustrial levels by the end of this century—enough to decrease global GDP by an estimated 25%, according to the Group of Thirty,1 a nonprofit assembly of experts focused on global economic risks.


Though this projected erosion of global gross domestic product (GDP) may seem like a long-term threat, it’s already on executives’ minds. For good reason: When GDP declines, the stock market also tends to dip, along with reduced consumer spending and corporate earnings. “Climate change will likely become a more central feature of corporate decision-making in the years ahead,” says Jonathan Kozy, senior macro strategy analyst in the Chief Investment Office (CIO) for Merrill and Bank of America Private Bank.


A widening array of environmental investing choices

“For investors, current climate trends suggest making environmental considerations a part of their long- and short-term portfolio strategies,” adds Sarah Norman, senior investment strategist in the Chief Investment Office for Merrill and Bank of America Private Bank. Growing evidence suggests that businesses with forward-looking environmental strategies may do better financially and, hence, be better long-term choices for investors. One report, for example, finds companies that reduce the costs of resources such as water, carbon and raw materials may improve their operating profits by up to 60%.2 Companies that fall behind, meanwhile, could risk greater costs due to regulation. “Another study estimates that as much as a third of corporate profits are at risk from state intervention,” Kozy says.3


Fortunately, a widening universe of environmental, social and governance (ESG) choices offers opportunities to help investors mitigate the portfolio risks created by the long-term effects of climate change and benefit from the growth potential of cleaner industries, even as they help the planet. Here, Kozy and Norman, two of the co-authors of the CIO report “Sustainable Investing Under a New Administration: The E in ESG,” discuss some of the strategies you might consider.


3 approaches: The ABCs of environmental investing

Investors interested in incorporating the “E” in ESG into their investing strategy might consider the “ABC Framework,” three distinct approaches to environmental investing as outlined by The Impact Management Project (IMP). IMP is an organization that provides a forum for building global consensus on measuring, managing and reporting impacts on sustainability, says Norman.


Avoid. Among the earliest forms of ESG investing, this approach involves screening out certain companies or industries based on practices an investor deems harmful. “This could include reducing or eliminating exposure to carbon-intensive industries, divesting from those that you believe are engaging in harmful deforestation or otherwise harming biodiversity, or reducing your exposure to companies or industries that consume major amounts of natural resources,” Kozy says. Such companies and industries could face stiff environment-related costs, especially at a time of heightened regulations.

Benefit. This involves investing in companies, regardless of industry, that are leading by example, incorporating environmental practices into their governance — and providing visibility into their efforts via ESG metrics and disclosures, Norman notes. For example, companies may demonstrate the ways their practices align with the United Nations’ Sustainable Development Goals (SDGs), or the Task Force on Climate-related Financial Disclosures (TCFD) or the Sustainability Accounting Standards Board (SASB). In 2020, the World Economic Forum’s International Business Council, chaired by Bank of America CEO Brian Moynihan, announced a set of “stakeholder capitalism metrics” designed to standardize ESG reporting across industries and regions.


“Doing so can benefit companies by mitigating the potential costs of regulatory and government pressure, as well as risks to their reputations,” Norman says. Positive environmental practices could also make such companies more prosperous and hence potentially stronger investments. In one survey, 70% of consumers said they would pay a 5% premium for a “green” product, compared with a similar non-green alternative.4 “Companies with a strong environmental strategy may differentiate themselves from the competition and find it easier to attract, retain and motivate talented workers,” Kozy says.


Contribute. The final group includes companies and industries whose products or services are dedicated to helping mitigate climate change. “These might include resource-efficient or alternative energy, smart grids, electric vehicles or innovations in food, agriculture, forestry and clean water,” Norman says. Renewable energies offer one clear example, she adds. “Between 2009 and 2019, solar energy costs fell by 90%, while utility-scale wind energy costs declined by 71%, making them competitive with conventional power generation.”5 Another boost is the current administration’s promise to ramp up investment in green infrastructure. The 2021 American Jobs Plan proposes hundreds of billions of dollars for everything from electric vehicles to a reenergized power infrastructure and building and retrofitting millions of energy-efficient homes.6


Choose the appropriate level of risk for you

The specific investments you choose may depend on your return expectations and your appetite for risk, Kozy says. For example, green bonds, an environmental community loan fund, or municipal bonds focused on sustainable cities or the transition from traditional to renewable energies may offer a modest return in exchange for relatively low risk. Other approaches, such as stocks in companies driving environmental solutions or private equity investments in renewable energy, may offer higher return potential in exchange for greater risk.


As with any investment strategy, it’s important to consider any environmental investments in the context of your overall assets and your personal financial goals, Kozy says. Your advisor can help you determine whether investing in climate-change solutions could also help you build a stronger portfolio.

All recommendations must be considered in the context of an individual investor’s goals, time horizon, liquidity needs and risk tolerance. Not all recommendations will be in the best interest of all investors.


Impact investing and/or Environmental, Social and Governance (ESG) managers may take into consideration factors beyond traditional financial information to select securities, which could result in relative investment performance deviating from other strategies or broad market benchmarks, depending on whether such sectors or investments are in or out of favor in the market. Further, ESG strategies may rely on certain values based criteria to eliminate exposures found in similar strategies or broad market benchmarks, which could also result in relative investment performance deviating.


Investments have varying degrees of risk. Some of the risks involved with equity securities include the possibility that the value of the stocks may fluctuate in response to events specific to the companies or markets, as well as economic, political or social events in the U.S. or abroad.  Investing in fixed-income securities may involve certain risks, including the credit quality of individual issuers, possible prepayments, market or economic developments and yields and share price fluctuations due to changes in interest rates. When interest rates go up, bond prices typically drop, and vice versa. Income from investing in municipal bonds is generally exempt from Federal and state taxes for residents of the issuing state. While the interest income is tax-exempt, any capital gains distributed are taxable to the investor. Income for some investors may be subject to the Federal Alternative Minimum Tax (AMT).


Alternative investments are speculative and involve a high degree of risk.


Alternative investments are intended for qualified investors only. Alternative Investments such as derivatives, hedge funds, private equity funds, and funds of funds can result in higher return potential but also higher loss potential. Changes in economic conditions or other circumstances may adversely affect your investments. Before you invest in alternative investments, you should consider your overall financial situation, how much money you have to invest, your need for liquidity, and your tolerance for risk.


An investment in Green Bonds involves risks similar to an investment in debt securities of the issuer, including issuer credit risk and risks related to the issuer’s business. You should review the relevant offering document carefully before investing.
