ESG investing has a sustainability blindspot: Supply chains


When you personal shares, likelihood is good you’ve got heard the time period ESG. It stands for environmental, social, and governance, and it’s a technique to laud company leaders who take sustainability—together with local weather change—and social duty severely, and punish those that don’t.

In lower than 20 years since a United Nations report drew consideration to the idea, ESG investing has advanced into a $35 trillion industry. Cash managers overseeing one-third of total U.S. assets under management said they used ESG criteria in 2020, and by 2025 world belongings managed in portfolios labeled “ESG” are anticipated to achieve $53 trillion.


These investments have gained momentum partially as a result of they cater to buyers’ rising want to have a constructive affect on society. By quantifying a firm’s actions and outcomes on environmental, social, and governance points, ESG measures provide buyers a technique to make knowledgeable buying and selling selections.

Nevertheless, buyers’ belief in ESG funds could also be misplaced. As students within the subject of supply chain management and sustainable operations, we see a main flaw in how score companies, reminiscent of Bloomberg, MSCI, and Sustainalytics, are measuring firms’ ESG threat: the efficiency of their provide chains.

The issue with ignoring provide chains

Almost each firm’s operations are backed by a global supply chain that consists of staff, info, and assets. To precisely measure a firm’s ESG dangers, its end-to-end provide chain operations have to be thought of.

Our recent examination of ESG measures reveals that the majority ESG score companies don’t measure firms’ ESG efficiency from the lens of the worldwide provide chains supporting their operations.

For instance, Bloomberg’s ESG measure lists “provide chain” as an merchandise beneath the “S” (social) pillar. By this measure, provide chains are handled individually from different objects, reminiscent of carbon emissions, local weather change results, pollution, and human rights. This implies all these objects, if not captured within the ambiguous “provide chain” metric, mirror every firm’s personal actions however not their provide chain companions’.

Even when firms gather their suppliers’ efficiency, “selective reporting” can come up as a result of there isn’t any unified reporting normal. One latest research discovered that firms are likely to report environmentally accountable suppliers and conceal “unhealthy” suppliers, effectively “greenwashing” their supply chain.


Carbon emissions are one other instance. Many firms, reminiscent of Timberland, have claimed nice successes in lowering emissions from their very own operations. But the emissions from their provide chain companions and clients, referred to as “Scope 3 emissions,” could stay excessive. ESG score companies haven’t been in a position to adequately embrace Scope 3 emissions due to a lack of data: Solely 19% of firms within the manufacturing business and 22% within the service business disclose this information.

Extra broadly, with out accounting for a firm’s complete provide chain, ESG measures fail to mirror world provide chain networks that at the moment’s huge and small firms alike rely upon for his or her day-to-day operations.

Amazon and the third-party-supplier drawback

Amazon, for instance, is amongst ESG funds’ largest and favorite holdings. As a firm bigger than Walmart by way of annual gross sales, Amazon has reported emissions from transport which might be solely one-seventh of Walmart’s. However when researchers for 2 advocacy teams reviewed public information on imports, they discovered solely about 15% of Amazon’s ocean shipments might be tracked.

As well as, Amazon’s determine doesn’t mirror emissions generated by its many third-party sellers and their suppliers who function exterior the U.S. This distinction issues: Whereas Walmart’s provide chain depends on a centralized procurement technique, Amazon’s provide chain is very decentralized—a large percentage of its income comes from third-party suppliers, about 40% of which promote straight from China, which additional complicates emissions monitoring and reporting.

One other essential ESG metric issues client safety. Amazon prides itself as “Earth’s most customer-centric company.” Nevertheless, when its clients have been injured by merchandise bought by third-party sellers on its platform, Amazon has argued that it shouldn’t be held responsible for the harm, as a result of it capabilities as an “on-line market” matching patrons and sellers. Amazon’s overseas third-party sellers are often not subject to U.S. jurisdiction so can’t be held accountable.

But main ESG score companies don’t seem to mirror the availability chain implication on buyer safety when measuring Amazon’s provide chain efficiency.

For instance, in 2020, MSCI, the biggest ESG scores company, upgraded Amazon’s ESG score from BB to BBB, reflecting its power in areas reminiscent of corporate governance and data security, regardless of its consumer liability risk.

These gaps are additionally issues for scores of firms reminiscent of 3M, ExxonMobil, and Tesla.

Different international locations are including strain

At the moment there isn’t any unified reporting normal, so totally different firms could cherry-pick sure ESG efficiency measures to report in an effort to enhance their sustainability and social scores.

To enhance consistency, the following step could be for ESG score companies to revamp their methodology to take into consideration what could also be environmentally dangerous and unethical operations throughout your entire world provide chain. ESG score companies may, for instance, create incentives for firms to gather and disclose their provide chain companions’ actions, reminiscent of Scope 3 emissions.

In June 2021, the German Parliament handed the Supply Chain Due Diligence Act, which is able to turn into efficient in 2023. Below this new regulation, giant firms primarily based in Germany shall be liable for social and environmental points arising from their world provide chain networks.


This consists of prohibitions on youngster labor and compelled labor, and a focus to occupational well being and security all through your entire provide chain. Those that violate the regulation face a fine of up to 2% of their annual income.

The European Union’s new Sustainable Finance Disclosure Regulation, which went into impact in March 2021, provides strain in a totally different method. It requires funds to report particulars on how they combine ESG traits into their funding selections. That has led some money managers to drop the phrase “ESG built-in” from a few of their belongings, Bloomberg reported.

With out related legal guidelines within the U.S., we consider ESG score companies may fill an essential hole. To make certain, surveying a firm’s complete provide chain’s ESG efficiency is much extra complicated. But by tying all of the ESG dimensions to a firm’s provide chain end-to-end operations, score companies can nudge company leaders to be liable for actions throughout their provide chains that might in any other case be saved at nighttime.
