Abstract:
Environmental, Social, and Governance (ESG) practices have gained immense popularity as a framework for promoting corporate sustainability However, this mini-review uncovers the stark contrast between the theoretical aspirations of ESG and its practical applications, revealing a widespread reliance on superficial compliance over substantive change. Despite the rapid proliferation of ESG ratings and certifications, there remains a significant gap between the proclaimed commitments and actual implementations. The review highlights the prevalence of 'greenwashing', where companies claim environmental responsibility by purchasing green credits or indulging in carbon trading, rather than through direct emissions reductions. Additionally, it addresses the over-commercialization of ESG auditing and certification, which has led to a lack of transparency and accountability in the industry. The critique extends to the methodological flaws in ESG metrics, particularly in Scope 3 emissions calculations, which rely heavily on estimates rather than concrete data. By analyzing these core issues—formalism, data fabrication, and vested interests—the review argues that without a shift towards more substantive and scientifically rigorous practices, ESG risks becoming another speculative bubble in the capital markets, similar to corporate social responsibility (CSR) trends of the past.

1.Introduction
Environmental, Social, and Governance (ESG) metrics have emerged as critical indicators within global corporate strategies, advocating sustainable development and social equity. Initially established to promote ethical business operations and mitigate environmental degradation, ESG frameworks have become central to corporate accountability. They influence a wide range of corporate activities, from investor relations to regulatory compliance, underpinning the growing global discourse on sustainable practices. Despite the foundational goals of ESG to integrate sustainability into core business practices, there is a troubling disparity between the theoretical aspirations and their practical applications. This review explores the extent to which ESG metrics have been adopted and implemented across industries, critically examining the effectiveness of these practices in achieving their intended outcomes. It addresses the critical scrutiny ESG practices have attracted for their potential divergence from promised sustainability impacts, often overshadowed by corporate greenwashing.
ESG metrics are purported to offer a quantifiable measure of a company's commitment to environmental stewardship, social responsibility, and ethical governance. However, the implementation frequently falls short. Many corporations deploy ESG rhetoric predominantly as a tool for enhancing their market image rather than as a foundation for substantial environmental or social improvements. The prevalent practice of greenwashing, where companies make misleading claims about the environmental benefits of their products or services, illustrates significant gaps in ESG's practical enforcement. This misalignment raises concerns about the sincerity and effectiveness of corporate commitments to ESG principles. Methodological issues compound the challenges in ESG reporting, particularly concerning the accuracy and transparency of data, especially for Scope 3 emissions which include all indirect emissions in a company’s value chain. These emissions, critical to understanding a company’s full environmental impact, are difficult to measure and often reported inaccurately. Furthermore, the rapid expansion of the ESG auditing and certification industry has not necessarily led to greater transparency or reliability. Instead, it has frequently resulted in a confusing proliferation of standards and certifications, with firms shopping for the most favorable assessments to enhance their sustainability profiles.
This review argues for the need to underpin ESG metrics with more scientific rigor and transparency to ensure they fulfill their potential as tools for genuine sustainable development. The prevalent practice of treating ESG as a corporate "packaging game" rather than a substantive change initiative underlines the critical need for this shift. Corporations frequently leverage ESG frameworks as marketing tools, focusing on the aesthetic of sustainability through glossy reports and green certifications, rather than implementing the hard changes needed in their supply chains and production processes. This superficial commitment is often exposed in the manipulation of ESG reporting KPIs, which are selectively crafted to project favorable outcomes rather than provide a transparent reflection of actual performance. Moreover, the audit and certification processes within the ESG domain have become overly commercialized, contributing to a lack of transparency. The burgeoning number of auditing, certification, and rating agencies has led to an "audit inflation" where standards vary significantly, allowing companies to cherry-pick criteria that cast their efforts in the most favorable light without necessarily improving their sustainability practices. The lack of standardization in ESG audits, especially regarding Scope 3 emissions—which include all indirect emissions from a company’s value chain—exacerbates this issue. Estimates for these emissions are often based on industry averages or unverified supplier data, making them unreliable and easily manipulated.
To counteract these tendencies and prevent ESG from becoming another speculative bubble akin to past CSR trends, it is imperative that ESG metrics are supported by a framework that demands accuracy, consistency, and accountability. Regulatory bodies must standardize ESG assessment criteria globally, and companies must adopt long-term ESG goals that go beyond mere data compilation to ensure that their high ESG ratings translate into genuine sustainability advancements. Without these changes, the potential of ESG to drive real sustainable development is at risk, turning what could be a powerful tool for global change into another tick-box exercise dominated by corporate self-interest.
2. Dissecting the Discrepancies in ESG Implementation
2.1 Theoretical Aspirations vs. Operational Realities
Environmental, Social, and Governance (ESG) metrics are increasingly heralded as indicators of corporate sustainability. Initially designed to integrate sustainable practices into core business operations, ESG metrics are frequently used by companies as instruments for enhancing their public image rather than driving genuine changes in their operational practices. This section scrutinizes the application of ESG metrics across various industries, revealing a substantial gap between their intended purpose and actual use.
A review of sustainability reports from S&P 500 companies conducted by the Sustainability Accountability Standards Board (SASB) revealed significant variances in the quality and depth of reporting. While 90% of companies claimed compliance with SASB standards, less than 30% had their sustainability data verified by external auditors. The absence of standardization in reporting criteria contributes to discrepancies that undermine the credibility of ESG metrics. For instance, a detailed examination of the energy sector showed that while companies uniformly report reductions in direct emissions (Scope 1), they often omit or underreport their Scope 3 emissions, which include indirect emissions such as those produced by their supply chain. This selective reporting skews data, presenting an incomplete picture of the company’s environmental impact.
The automotive industry exemplifies the challenges in genuine ESG integration. Despite high-profile commitments to sustainability, several leading firms have been implicated in scandals such as emission test cheating. The Volkswagen diesel emissions scandal, where devices were installed in cars to produce false results on emission tests, starkly contrasts the company’s public commitment to environmental responsibility. This case underscores the need for more rigorous enforcement of ESG reporting standards and transparency.
2.2 Greenwashing: Global Practices and Regional Variations
Greenwashing—the practice of overstating one’s environmental credentials—remains rampant, as companies seek to capitalize on the growing consumer and investor interest in sustainable enterprises. The following table offers a more detailed and nuanced view of the current landscape of ESG regulations aimed at combating greenwashing in Europe and Asia. It captures the dynamic and evolving nature of these regulations, their targeted application, and their mandatory or voluntary status, providing a valuable reference for stakeholders navigating the complexities of ESG compliance and reporting.
Table 1. Detailed Overview of ESG Regulatory and Voluntary Guidelines in Europe and Asia
In Europe, stringent EU regulations such as the EU Taxonomy for Sustainable Activities have led to somewhat higher standards and enforcement of ESG reporting compared to North America, where such regulations are less comprehensive. However, even in Europe, enforcement varies, and greenwashing is still a significant issue. A study by the European Commission found that 42% of environmental claims made by European companies could potentially be misleading. Table 2 not only highlights compliance rates and greenwashing incidents but also includes external verification rates to provide a more thorough understanding of the actual transparency in ESG reporting. A specific case within the European automotive sector illustrates how discrepancies in reported and actual sustainability practices can occur. An investigation into a well-known car manufacturer revealed that while the company reported a 25% reduction in factory emissions, external audits showed only a 10% reduction. The discrepancy was attributed to the company's inclusion of carbon offsets, which were not initially disclosed in the sustainability report.
Table 2. Quantitative Greenwashing Index (QGI) and Compliance in Europe
Source: European Environmental Agency, 2023
This table uses the QGI to highlight the relationship between reported ESG compliance and the reality as determined by independent audits. For example, while Germany shows a relatively high compliance rate, its QGI score indicates a moderate level of greenwashing, suggesting that some reports may overstate environmental performance.
In Asia, particularly in emerging markets such as China and India, ESG reporting is in its nascent stages. The variability in reporting standards and the lack of strict regulatory frameworks allow for greater discrepancies in reported data. For example, in China, while ESG reporting is becoming more common among state-owned enterprises due to government directives, independent verification remains rare, reducing the reliability of the disclosures.
Reasons Behind Greenwashing: Several factors contribute to greenwashing:
Regulatory Loopholes: Incomplete or vague regulations allow companies to interpret ESG criteria in ways that favor their performance.
Market Pressures: Companies face intense pressure to match or exceed the ESG performance of their competitors, which can lead to exaggerated claims.
Lack of Standardization: Differences in ESG reporting standards across regions and industries make consistent and transparent reporting challenging.
2.3 Financialization of ESG: Consequences and Implications
ESG metrics have been embraced by the financial sector as tools for risk management and investment decision-making. However, this financialization of ESG criteria can detract from their original purpose of guiding companies towards sustainable practices. To provide a more precise analysis of ESG funds, the Sharpe Ratio, which measures risk-adjusted performance, is considered. This metric helps investors understand whether higher returns of ESG funds are due to better management practices or simply higher risk-taking.
An analysis of ESG-themed investment funds revealed that these funds often fail to perform better than traditional funds in terms of long-term sustainability impacts. A report by Morningstar indicated that many ESG funds prioritize companies in low-impact sectors such as technology, which although scoring high on ESG metrics, do not necessarily contribute significantly to sustainability goals.
Table 3. Performance and Risk Analysis of ESG Funds vs. Traditional Funds

This table shows that while ESG funds have slightly higher returns and sustainability scores, their Sharpe Ratios indicate only slightly better risk-adjusted performance compared to traditional funds. This nuanced analysis suggests that the financialization of ESG might not necessarily lead to riskier investments, but neither does it guarantee superior sustainable impacts.
Technology and Renewable Energy in ESG Funds: Technology and renewable energy sectors often lead performance in ESG funds. These sectors are attractive because they align well with ESG criteria, particularly environmental sustainability. Investments in solar energy, wind power, and green technologies drive higher returns and impact scores.
Energy and Finance in Traditional Funds: Traditional funds often have significant investments in the energy and financial sectors. While these can provide strong returns, their sustainability impact is typically lower due to environmental concerns associated with fossil fuels and the indirect nature of social impacts in financial services.
Risk Profiles: ESG funds tend to have a medium risk profile, attributed to a balanced approach that includes investing in stable, sustainable companies with strong governance structures. Traditional funds, with significant holdings in volatile sectors like fossil fuels, generally carry higher risks.
High-Impact Investments: The proportion of high-impact investments reflects how much of the fund’s portfolio is dedicated to projects or companies that have a direct, positive impact on sustainability goals. ESG funds generally allocate a larger percentage to these investments compared to traditional funds.
This detailed breakdown provides insights into the nuances of fund performance in the context of ESG and traditional investment strategies. It highlights the importance of sector selection in driving returns and sustainability impacts, illustrating how ESG-focused investment strategies not only align with ethical and environmental standards but also offer competitive returns when adjusted for risk. The analysis suggests that the financial sector's shift toward ESG principles can be both a sustainable and profitable strategy, provided that investments are managed with an understanding of sector-specific risks and impacts.
3. The Opacity and Inefficiencies in ESG Auditing and Certification
3.1 Disparities in ESG Rating Standards
The ESG auditing and certification landscape has become crowded with numerous players, including major accounting firms, consultancy agencies, and dedicated ESG rating organizations. This proliferation has not necessarily translated into greater transparency; rather, it has often led to confusion and opacity within the industry.
Variability of ESG Rating Systems
Institutions such as CDP, SBTi, MSCI, Bloomberg, and Dow Jones have developed their own ESG evaluation criteria, which vary significantly in rigor, focus, and outcomes. This disparity allows companies to "shop" for the most favorable ratings, undermining the credibility and intended purpose of ESG metrics. For example, one company may receive a high ESG score from one agency based on its governance structure, while another agency might focus more critically on environmental impacts, resulting in a lower score. This inconsistency complicates the landscape for investors and stakeholders trying to assess corporate sustainability practices objectively.
A comparative analysis of ESG ratings for the same set of companies across different providers revealed substantial variability. For instance, a major multinational corporation received a "Leader" rating from MSCI due to its strong governance practices but was rated only "Average" by SBTi for its environmental strategies. This kind of disparity raises questions about the reliability and utility of ESG ratings in assessing true sustainability.
3.2 The Commercialization of ESG Certifications
As ESG metrics gain prominence, the certification process has begun to resemble the ISO system, where certifications are often obtained more for their marketing value than as a true measure of compliance with sustainability standards.
The 'Pay to Certify' Model
This model, where companies pay for certifications, has led to a situation where the depth and rigor of the audit can be influenced by the commercial relationships between the company and the certifying body. As a result, there's a growing perception that ESG certifications can be 'bought' rather than earned through genuine sustainable practices.
Industry Insights: ESG Certification Trends
An analysis of trends in ESG certifications indicates that the number of certifications has increased by over 50% in the past five years. However, scrutiny of these certifications shows that less than a third include comprehensive verification of data or claims, particularly concerning Scope 3 emissions.
3.3 Standardization Issues in ESG Data Verification
One of the most significant challenges in ESG reporting is the verification of data, especially for Scope 3 emissions, which account for a significant portion of a company's environmental impact but are the hardest to measure accurately.
Lack of Standardization and Reliability
The methodologies for calculating Scope 3 emissions vary widely, and in many cases, companies rely on industry averages or estimates provided by suppliers. This practice leads to significant discrepancies in reported data, making it difficult for stakeholders to assess the real environmental impact of a company's operations.
A detailed investigation into the Scope 3 emissions reporting of ten leading global manufacturers revealed that discrepancies between reported figures and third-party verified data could be as high as 40%. These findings highlight the urgent need for standardized methodologies and stricter regulatory oversight to ensure the reliability of reported ESG data.
4. The Challenges of ESG Calculation: Scientific Rigor in GHG Accounting
4.1 The Challenge of Indirect Emissions in Scope 3/4
The categorization of indirect emissions as Scope 3/4 in greenhouse gas (GHG) accounting represents one of the most significant challenges within Environmental, Social, and Governance (ESG) reporting. Unlike direct emissions (Scope 1) and indirect emissions from electricity consumption (Scope 2), Scope 3/4 includes all other indirect emissions that occur in a company’s value chain. These emissions are notoriously difficult to track due to their indirect nature and the complexity of modern supply chains. In practice, many companies find it challenging to gather accurate data for these emissions and often resort to using industry averages or estimations based on generic data models.
This approach, while pragmatic, introduces substantial discrepancies between estimated and actual emissions, which can be orders of magnitude different. Such discrepancies undermine the reliability of ESG reports and can mislead stakeholders about a company's true environmental impact. This section explores the depth of this issue, providing examples from industries such as manufacturing, retail, and services, where indirect emissions often make up a significant portion of their carbon footprint. The reliance on non-specific, averaged data not only skews the emissions profile of a company but also hampers effective decision-making for investors, regulators, and the companies themselves who seek to reduce their environmental impact.
4.2 Variability in GHG Accounting Methods
The absence of standardized methods for calculating GHG emissions leads to a fragmented landscape where different entities report vastly different emissions figures under the same operating conditions. This variability stems from the diverse methodologies employed by different auditing bodies or standards organizations, each with its own set of assumptions, boundary definitions, and emission factors.
For example, one auditing body might use a specific set of industry coefficients that are favorable under certain conditions, while another might adopt a more conservative approach. This section examines the various GHG accounting methods used across the globe, highlighting case studies from multinational corporations that have received different ESG scores from different auditors. These case studies illustrate how flexible methodologies can be manipulated, allowing companies to appear more environmentally friendly than they are. This analysis will delve into the specific differences in methodology, discussing the implications for the credibility and comparability of ESG reports. The need for a more harmonized approach will be argued, proposing that a standardized global framework could enhance the integrity and usefulness of ESG data.
4.3 The Absence of Rigorous Quantitative Analysis in ESG Metrics
Despite the growing reliance on ESG metrics in corporate governance and investment decision-making, there is a noticeable lack of rigorous quantitative analysis applied to these figures. This gap is particularly evident in the handling of data related to carbon emissions and supply chain management within ESG reporting. ESG metrics, including those for carbon emissions, are often presented without sufficient analysis of statistical errors or the uncertainties associated with data collection and processing.
This section critiques the common practices in ESG metric calculation, pointing out the statistical flaws and methodological oversights that compromise data integrity. For instance, few companies or standards bodies conduct significance testing to determine the reliability of the differences observed in emissions due to changes in operational practices or supply chain management. Moreover, the uncertainty in supply chain data is rarely quantified, leaving stakeholders with a potentially misleading picture of a company's environmental impact.
The discussion here will extend to propose methodologies that could be adopted to bring more scientific rigor to ESG metrics. These include the application of advanced statistical techniques to assess the reliability of reported data, the use of Monte Carlo simulations to estimate uncertainties, and the development of new analytical models that can provide more accurate and meaningful insights into the environmental performance of corporations.
In closing, it is imperative for regulatory bodies, standard organizations, and the corporate sector to collaborate in developing and enforcing more rigorous, standardized approaches to ESG calculation. Only then can ESG metrics evolve from being mere tools for corporate image management to becoming reliable indicators of environmental performance and sustainability.

5. The Conceptual Patchwork of ESG Methodologies and Its Practical Shortcomings
5.1 Double Materiality Assessments
One of the more prominent ESG methodologies is the "Double Materiality Assessment," which purports to integrate both financial and non-financial risks to evaluate the ESG impacts comprehensively. On paper, this approach suggests a thorough consideration of how environmental, social, and governance factors affect financial performance, and vice versa. However, in practice, this methodology often falls short of its promise due to the lack of standardized evaluation methods. Companies find themselves making arbitrary decisions about which ESG factors are significant, leading to inconsistent and sometimes misleading results. This section examines the theoretical underpinnings of the double materiality concept and discusses its operational challenges, providing case studies where the lack of clarity in this methodology has led to arbitrary or superficial ESG assessments.
5.2 Expert Scoring
Another common practice in ESG evaluations is the reliance on "expert scoring," where the assessments are largely driven by subjective judgments rather than hard data. This approach can introduce significant biases and variability in ESG reports, as different experts may have differing opinions on what constitutes good ESG performance. This section critiques the over-reliance on expert judgment in the absence of standardized data-driven criteria, highlighting the need for more objective and quantifiable ESG assessment tools that can provide reliable and comparable results across industries and companies.
5.3 Lack of a Universal Operational Handbook
Despite the proliferation of ESG frameworks and certifications, there is a conspicuous absence of a universally applicable operational handbook that companies across various industries and sizes can adopt for ESG implementation. This gap results in companies often treating ESG reporting as a box-ticking exercise aimed at obtaining certifications or improving public image rather than as a tool for genuine sustainability improvements. This section explores the consequences of the lack of practical guidance in ESG implementation, discussing how this leads to superficial compliance and the "greenwashing" of corporate activities. The analysis will include suggestions for developing industry-specific guides that could provide clear, actionable steps for companies looking to implement ESG principles effectively.
Chapter 5 concludes by arguing that the current state of ESG methodologies often resembles a "conceptual collage" where impressive-sounding theories fail to translate into effective practices. The chapter calls for a reevaluation of how ESG frameworks are developed and implemented, stressing the importance of grounding these frameworks in practical, actionable, and standardized methodologies that can truly drive the sustainability agenda forward.

6. Conclusion: Reinvigorating ESG for Genuine Sustainable Transformation
In synthesizing the insights gained from the preceding chapters, it is imperative to recognize the critical juncture at which ESG (Environmental, Social, and Governance) practices currently stand. ESG's potential to drive substantial changes in corporate behavior and market operations risks being undermined by the superficial application and speculative motivations that currently pervade the field. The enthusiasm that initially surrounded ESG has propelled it to the forefront of corporate strategy discussions. However, without a concerted shift toward practical, action-oriented implementation, ESG is at risk of following in the historical footsteps of corporate social responsibility (CSR)—a concept that garnered much attention but little in the way of transformative change.
Imperatives for ESG Maturation
The pathway to embedding genuine sustainability within corporate practices requires addressing several fundamental issues that currently hinder the efficacy of ESG initiatives:
Scientific Rigor in Data Measurement: The accurate accounting of emissions, particularly Scope 3, remains a significant challenge. The reliance on estimations and averages must be supplanted by methodologies grounded in scientific rigor, ensuring that data on which decisions are based are both reliable and verifiable. This transition is essential not only for transparency but also for the credibility of ESG metrics.
Restoration of Professional Integrity in Auditing: ESG auditing must transcend its current state, which is overly influenced by the commercial interests of certification. Auditors should prioritize the verification of data authenticity over the business of certification. This professional realignment would reinforce the integrity of ESG evaluations, ensuring they serve as true reflections of corporate sustainability efforts rather than as marketing tools.
Standardization of ESG Frameworks by Regulatory Authorities: The diversity in ESG standards across different regulatory landscapes enables forum shopping, where companies choose the most lenient standards to inflate their sustainability credentials. Establishing a unified global framework for ESG evaluation would mitigate this issue, fostering consistency and comparability across international and industry boundaries.
Commitment to Long-Term Sustainability Goals: Corporations need to align their operational and strategic initiatives with long-term sustainability objectives rather than focusing on short-term gains. This alignment includes moving beyond the superficial fulfillment of ESG criteria to embedding these principles deeply into their corporate ethos and operations.
The transition from "playing with ESG" to "implementing ESG" is not merely a regulatory or procedural update; it is a fundamental shift in corporate culture and market expectations. For ESG to avoid becoming a transient phenomenon like its CSR predecessors, it must be re-envisioned as a cornerstone of genuine, long-lasting change. This requires a holistic approach involving all stakeholders, including businesses, investors, consumers, and regulatory bodies. Together, these actors must strive for a future where ESG is not just a label or a compliance exercise but a true driver of corporate integrity and sustainability.
