A Critical Lens on ESG and ESG Ratings

Introduction


ESG, which stands for environmental, social, and governance, has gained significant traction in recent years. The importance of ESG is evident in the increasing number of internet searches and the growing adoption of ESG reporting by companies. Over 90% of S&P 500 companies and 70% of Russell 1000 companies now publish ESG reports[1]. The rise of ESG can also be seen in the investment landscape, with sustainable funds experiencing significant inflows. Global sustainable assets reached $2.5 trillion in mid-2022[2].

In light of the conflict in Ukraine and its far-reaching consequences, critics have raised doubts about the long-term significance of ESG[3]. They argue that attention will shift towards more fundamental elements of societal and economic needs, relegating ESG to a passing trend[4]. Additionally, some contend that ESG's combination of factors is unstable and that the focus should solely be on environmental sustainability[5]. Alongside these concerns, challenges to the integrity of ESG investing have emerged. However, this article focuses on the individual company level, examining whether ESG truly matters to businesses and the strategic rationale behind its adoption.


A critical lens on ESG

Criticisms of ESG are not new. As ESG has gone mainstream and gained support and traction, it has consistently encountered doubt and criticism as well. The main objections fall into four main categories.


1. ESG is not desirable, because it is a distraction

According to critics, one of the main objections to ESG is that it is viewed as a distraction from the core purpose of businesses, which is to maximize profits while adhering to societal rules[6]. They argue that ESG practices are often seen as a public relations move or a way to capitalize on the values of customers, investors, or employees. Critics claim that ESG is not foundational to company strategy and is seen as something "good for the brand" rather than essential[7]. Some critics even label ESG efforts as "greenwashing," "purpose washing," or "woke washing," implying that companies may not genuinely prioritize sustainability, ESG, or diversity, equity, and inclusion (DEI) commitments[8]. A survey by Edelman[9] revealed that nearly three out of four institutional investors do not trust companies to fulfill their sustainability, ESG, or DEI commitments.


2. ESG is not feasible because it is intrinsically too hard

A second critique of ESG is that implementing it in a way that resonates with multiple stakeholders is challenging. The objective of maximizing value for the corporation and shareholders is clear when solving for a financial return. However, when considering broader objectives and complex solutions, trade-offs arise. Managers face the dilemma of deciding where to allocate the incremental ESG dollar; should it go towards lower prices for customers, increased benefits or higher wages for employees, or addressing environmental issues through an internal carbon tax? The optimal choice is often unclear, and even if it existed, companies may lack a clear mandate from shareholders to prioritize ESG.


3. ESG is not measurable, at least to any practicable degree

A third objection raised by critics is the difficulty in accurately measuring ESG, especially when it comes to aggregate ESG scores. While individual dimensions of E, S, and G can be assessed if the required, auditable data is available, critics argue that overall ESG scores lack meaningfulness. This is due to differences in weighting and methodology among ESG ratings and scores providers. For instance, credit scores from S&P and Moody's show a 99% correlation, whereas ESG scores from six prominent providers have an average correlation of only 54%, ranging from 38% to 71%[10]. Additionally, organizations like the GRI and SASB may measure the same phenomenon differently. Different providers, incorporating their own analyses and weightings, naturally result in divergent scores. Major investors often rely on their proprietary methodologies, which include inputs from various sources, including ESG scores, honed over time.


4. Even when ESG can be measured, there is no meaningful relationship with financial performance

According to critics, positive correlations between ESG and outperformance may be explained by other factors and are not necessarily causative. It would be unreasonable to expect near-identical ESG ratings across different providers, methodologies, and industries to perfectly match company performance. Correlations with performance can be influenced by various factors such as industry trends and may change over time[11]. While most ESG-focused investment funds tend to outperform the broader market, some ESG funds do not, and alternative explanations for outperformance exist[12]. For example, technology and asset-light companies often score higher in ESG ratings due to their lower carbon footprint. Several studies have questioned any causal link between ESG performance and financial performance[13]. However, companies are still making significant decisions and commitments aligned with ESG considerations, indicating their growing importance in decision-making.


ESG ratings

The extent to which ESG, as measured by ratings, can offer meaningful insights about future financial performance is one of the most hotly contested issues surrounding environmental, social, and governance (ESG)—particularly when ratings and scores providers use various, and occasionally conflicting, methodologies. According to several research, there is a link between financial performance and ESG ratings[14]. According to other studies, while achieving high ESG ratings does not result in the destruction of financial value, the connection between ESG ratings at any particular time and value creation at that same time may be contentious or nonexistent[15].


Conclusion

While the relevance of ESG and its impact on financial performance continues to be a subject of debate, there is a growing recognition of the importance of ESG considerations in their strategic and decision-making processes. Companies are facing increasing pressure from various stakeholders to prioritize sustainability, social responsibility, and good governance. Despite the challenges in measuring and assessing ESG factors, companies are making significant commitments aligned with ESG, indicating their recognition of the importance of these considerations in today's business landscape.
