5 benefits of ESG investing

17 May 2022

Key points

  • The demand for Environmental, Social and Governance (ESG) investing is surging
  • Investors in different life stages wish to align their personal values to their financial goals
  • Sustainable investing offers numerous benefits from financial returns to helping the planet and the community

The demand for ESG investing is surging

ESG investing may surpass US$53 trillion in assets by 2025 on growing demand from global investors.1 In Asia, the appetite for sustainable investments soared in China (up 80% in 2021) and in Japan (rose 34% in 2018-2020).2 Demand for responsible investing has also grown among pre-retirees who wish to align their personal values to their retirement goals (U.S. public pensions applied ESG factors to at least $3 trillion in assets in 2018)3.

ESG investing is becoming the new investment strategy that offers diverse benefits to investors of any kind.4 What can be gained from adopting a sustainable investment approach? We list the five key benefits of ESG investing.

1. ESG investments may deliver outperformance (especially during down markets)

Outperformance is measured in terms of relative performance. It could mean more gain and less loss when compared with a benchmark fund or standard index. Investee companies that integrate ESG more thoroughly are generally considered better-run from a governance perspective, which helps financial performance. Here’s why.

ESG-focused companies have sustainability strategies and tend to have better operational efficiency, cost savings, lower employee turnover, innovation, retained talent, reduced compliance costs, and risk management — all of which may help to increase shareholder value.5

As for funds that carry ESG labels, we found that they have tended to outperform over the medium to longer term.6 According to Morningstar, over the 10-year period through 2019, more than 58.8% of sustainable funds outperformed (delivered higher returns than) their average traditional peers.7 Furthermore, over 77% of these funds still exist today, while more than half (53%) of traditional funds have dissolved.8 Indeed, research shows that funds considering ESG factors were able to outlast and outperform their conventional, non-ESG counterparts.

What’s more, ESG funds have also shown resilience during periods of heightened market volatility. An MSCI study compared three global ESG indexes with the parent gauge, MSCI All Country World Index ACWI, during the first quarter of 2020 (the onset of the COVID-19 sell-off) and found that the ESG measures outperformed the traditional benchmark (MSCI ACWI) over the same period and onwards (See Chart 1).

2. Potential to help the environment and help solve climate change

In the past few decades, human activities have contributed to climate change, biodiversity loss and the erosion of the world’s wildlife, plants, and marine environments. Overall, public pressure is rising for corporates and governments to play more active roles on sustainability.

Investing in ESG-oriented companies can potentially help the environment and mitigate climate change. Green bonds, for example, are focused on environmental objectives, including reducing carbon emissions to improve air quality. As data from J.P. Morgan ESG Asia Credit Index (JESG JACI) vs. J.P. Morgan Asia Credit Index (JACI) demonstrate, the JESG JACI emitted less carbon dioxide (CO2) for every US$1 million of revenue generated, implying a milder environmental impact (See Chart 2). Another example is investing in a rail network company. Transport by rail can result in 75% less greenhouse gas (GHG) emissions than trucking, creating an opportunity to gain customers, comply with environmental regulatory changes, and reduce GHG footprints.

3. Understand and manage portfolio risks with strong governance and ethical companies

It may not be obvious, but the economy, businesses, and nature are all intertwined. The environment plays an integral part in the global supply chain. More than half of the world’s total GDP (almost US$44 trillion economic value generated) is broadly dependent on nature, particularly in sectors like construction, agriculture, and forestry. Investors may be better positioned to enhance portfolio resilience by understanding the hidden risks of biodiversity and nature loss and its impact on the economy and investments.

Investing in ESG-oriented companies may reduce overall investment risk, given those companies’ stronger relative governance practices and better business ethics. A growing number of initiatives like the United Nations Principles for Responsible Investment (UNPRI) are requiring members to exercise the fiduciary duty of incorporating ESG factors in their investment decisions. Meanwhile, more stock exchanges are requiring ESG disclosures; exchanges in Hong Kong (HKEX) and Singapore (SGX), for instance, require listed companies to file annual ESG reports. (See Chart 3)

4. Another way to give back to the community and promote social responsibility

Historically, institutions and the wealthiest members of society have been the largest donors to philanthropic causes. These days, ESG investing offers more options for investors of any kind who are interested in making a positive social impact.

Investing in ESG-focused companies goes beyond financial returns, and places high priority on social benefits, such as protecting employee welfare and fostering relationships between businesses, shareholders, and communities.

From an employee’s standpoint, studies show that encouraging staff to act in a “prosocial” way correlates with higher job satisfaction and productivity (factors that play into mental health)9.

From a shareholder’s standpoint, a 2019 McKinsey study found that companies in the top quartile for diversity in gender or ethnicity on executive teams were 25 percent more likely to have above-average profitability than companies that had less diverse representation.10 (See Chart 4)

Last but not least, from a customer’s standpoint, corporate social responsibility (CSR) can also help companies build customer loyalty. Numerous studies indicate U.S. millennials are more likely to buy brands that support social issues they care about. And for the younger generation under the age of 40, instead of donating money directly to social causes, they would prefer to give back through the places they shop.11

5. Companies with sustainability plans may be better prepared to meet long-term investment goals

The benefits of ESG investing are more likely to be realised over a longer-term investment horizon. Equally, ESG risks and the negative impacts of unsustainable practices on financial returns are more likely to emerge over longer timeframes.

In general, companies are exposed to assets that depreciate over time due to changes in regulation, social expectations, disruptive technology, or environmental conditions.12 In this regard, companies with sustainability plans may be better prepared to anticipate and adapt to ESG-related changes. For example, a fossil-fuel company may need to decommission and write-down assets, cancel projects and replace them with renewable programs. A beverage manufacturer may be liable for a city’s water scarcity, face consequential legal risks, reputational and punitive damages, and loss of public trust if it has inadequate CSR policies.  

Conclusion: Investors see the benefits of ESG investing

From new retail investors to experienced professionals to pre-retirees, people around the world are beginning to recognise the benefits of ESG investing. ESG is fast becoming a mainstream long-term investment strategy, which can help investors align their financial goals with their personal values, as well as build a better and sustainable world.

6 Note: We consider that the integration of sustainability risks in the decision-making process is an important element in determining long-term performance outcomes and is an effective risk mitigation technique. Our approach to sustainability provides a flexible framework that supports implementation across different asset classes and investment teams. While we believe that sustainable investing will lead to better long-term investment outcomes, there is no guarantee that sustainable investing will ensure better returns in the longer term.  In particular, by limiting the range of investable assets through the exclusionary framework, positive screening and thematic investment, we may forego the opportunity to invest in an investment which we otherwise believe likely to outperform over time.
