2. Stakeholder Transparency
ESG risks call for stronger regulation, penalties, and transparency to prevent companies from behaving unsustainably and minimize externalities conveyed. Companies are expected to internalize sustainability into their strategy and culture to attain competitive advantage while reducing risks
[38] such as legal, reputational, and financial risks that can divert resources away from main businesses. With ESG considerations embedded into their practices, companies should communicate their ESG efforts by establishing a comprehensible metric of externalities involving the ecosystem and stakeholders
[39], which improves stakeholder transparency.
The treatment of ESG transparency overlaps with that of sustainability reporting, corporate social responsibility (CSR) reporting, and ESG disclosures in the literature. Commonality exists in that both reporting and disclosure aim to address transparency to stakeholders. While sustainability addresses a broader definition, CSR and ESG cover aspects of sustainability. Through ESG, sustainability is categorized into three components—environmental, social, and governance—and has become the most extensively used measurement of sustainability standards in current practice to hold companies accountable
[40].
The percentage of Fortune Global 250 firms allocating portions of their annual reports and CSR reporting to CSR activities grew from 44% in 2011 to 78% in 2017
[25], showcasing the growing norms of communicating sustainability among businesses. High ESG performance can provide “insurance-like” protection as these firms gain stakeholder trust and experience less criticism from stakeholders such as investors and regulatory bodies
[41][42]. Clark, Feiner, and Viehs (2015)
[43] note that the future of sustainable investing will involve active ownership by multiple stakeholder groups, which aligns with the growing trend of ESG integration.
2.1. Theoretical Underpinnings
Providing transparency about ESG efforts draws on existing organizational concepts of agency theory, legitimacy theory, stakeholder theory, and signal theory for substantiating the relationship between ESG transparency and firm valuation.
Legitimacy theory suggests that companies are operating in ways accepted by society to attain a social license to operate
[44]. Corporations will legitimize their actions through ESG transparency to ensure their continuing existence. Society may penalize firms for their negligence or reluctance towards ESG activities which can threaten firm survival. This theory is most cited among research papers exploring the relationship between sustainability and financial indicators.
Similarly, stakeholder theory originated from R. Edward Freeman in 1984, who argued that companies should consider other members of society who have connections to business activities to influence the success of products and services
[45]. This is backed by other studies
[46][47] where other stakeholders in society include employees, customers, suppliers, financiers, communities, and government. Societal stakeholders are thus key motivators for companies to engage in ESG practices
[48]. By doing so, ESG practices could increase shareholder value by improving reputation which attracts more customers, improving productivity for trained employees
[49], and minimizing regulatory costs.
The agency theory is based on two main pillars: the principal–agent relationship and the separation between ownership and control
[50]. The principal, otherwise the company owner or shareholder, delegates the managing power to the agent to act in the best interests of the principal
[51][52]. However, agents may pursue their own interests at the expense of the principal, resulting in agency cost and conflict
[53]. Principals are more focused on the long term while agents are more focused on short-term benefits. For this research, ESG disclosures are perceived to reduce agency costs via information asymmetry, which arises from the separation between ownership and control
[54]. The stronger the disclosure, the greater the transparency. ESG transparency can thus help reduce compliance costs, which can influence the risk profile and valuation of the firm
[55][56].
The signaling theory suggests that companies will reduce information symmetry present in imperfect markets by sharing information with stakeholders. ESG transparency hence signals a firm’s credibility and commitment towards sustainability to external stakeholders
[57][58].
Therefore, these theories provide the basis for why ESG transparency signals to stakeholders the extent to which the company is operating sustainably, making ESG integration an innovative sustainable investing strategy for firms to gain a competitive advantage. ESG transparency can be used to legitimize corporate activities towards creditors and shareholders, thus incentivizing efforts to engage in sustainability
[59]. This implies that higher ESG transparency reduces agency costs, and signals legitimacy to various stakeholder groups that firms have low compliance risk and minimal reputational risk, and hence deserve stronger valuation. Companies that behave less responsibly will be punished by the market
[60][61][62] and this can be reflected by a decrease in performance, such as sales and earnings, which are linked to their valuations.
2.2. Supporting Initiatives
To facilitate transparency, there exist several regulations and initiatives by different stakeholder groups in society that can be applied across sectors, with some developed for the palm oil sector itself. These include regulations, mandates by public exchanges, voluntary initiatives, certification schemes, and data and reporting platforms that enable stakeholders to access information about companies’ practices.
Regulations
Reporting regulations have been on the rise to motivate companies to strengthen their sustainability disclosures
[63]. Within the EU, the EU Taxonomy Regulation aims to develop a classification system for economic activities that are environmentally sustainable
[64]. Additionally, the EU’s Sustainable Finance Disclosure Regulation (SFDR) addresses ESG reporting obligations by requiring financial market participants to share how sustainability risks are managed
[64]. Newer developments include the European Sustainability Reporting Standards (ESRS) for entities subject to the Corporate Sustainability Reporting Directive (CSRD), which are required to be applied by large companies in their 2024 annual reports
[65]. These are mandated by the European Commission, based on draft standards developed by EFRAG (the European Financial Reporting Advisory Group)
[66]. At a global scale, the International Sustainability Standards Board (ISSB), set up by the International Financial Reporting Standards (IFRS) Foundation
[67], published its first sustainability-related disclosure standards known as IFRS S1 and IFRS S2, building upon existing market standards, to establish the global baseline for sustainability-related disclosures
[68]. These are critical in unifying standards on sustainability and promoting more transparent and credible ESG data and disclosures for stakeholders.
Public Exchanges
Public exchanges help foster market confidence by strengthening governance to promote ESG disclosures through listing requirements. This helps to protect companies’ reputations and facilitates competition among companies
[69]. In 2015, when the UN Sustainable Stock Exchanges (SSE) initiative launched its Model Guidance, less than a third of stock exchanges in the world provided ESG guidance, and by mid-2020 more than half of SSE’s members published ESG guidance
[70]. Public exchanges have mandated sustainability reporting for listed companies across Singapore, Hong Kong, Indonesia, Malaysia, and Thailand
[71], and large listed companies in Europe and the United Kingdom (UK)
[72]. For India, it will be mandated for the top 1000 largest companies from fiscal years 2022 to 2023
[71].
Voluntary Initiatives
To address information asymmetry about non-financial concerns between companies and investors
[73], there exists a wide range of standards and frameworks available for assessing ESG transparency through sustainability reporting and ESG disclosures. These include the UN Global Compact Network (GCN), the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), and the International Integrated Reporting Council (IIRC). There are also several data providers such as Bloomberg, Sustainalytics, Standard and Poor’s (S&P), and Morgan Stanley Composite Index (MSCI) who have their ESG metrics. These frameworks and databases have comprehensive guidelines covering ESG considerations, but these are not consistently used across industries and firms. Despite enabling transparency, the inconsistency makes the extent and quality of ESG disclosure heterogeneous
[29], creating challenges for stakeholders to assess and compare ESG performance.
Principle-based voluntary ESG initiatives have progressively been established to strengthen private investments, such as the UNPRI, UN Environment Programme (UNEP) Finance Initiative, Equator Principles, and Principles for Sustainable Insurance
[74]. In response to managing heterogeneous disclosures, the UNPRI, GSIA and the CFA Institute formed a collaboration to create an authoritative resource that harmonizes the different terms and definitions relating to ESG investment to make ESG disclosures more comparable and enhance the investors’ decision making while minimizing legal, compliance, and reputation risks
[75].
Certification
In the palm oil sector, certification is commonly used for companies to transparently communicate commitments to ESG. The most globally recognized is the Roundtable on Sustainable Palm Oil (RSPO), a voluntary certification set up in 2004 to promote sustainable palm oil
[76]. Its members comprise stakeholder groups in the value chain from producers, processors, traders, manufacturers, retailers, investors, and NGOs
[77]. The RSPO collaborates with government bodies to formulate legislative frameworks. However, its high visibility and association with greenwashing have highlighted weaknesses and garnered doubts about the certification’s credibility
[4], as observed in the earlier examples of labor challenges. RSPO certification is also costly to adopt, as it excludes smaller companies and smallholders from being recognized as sustainable. Nonetheless, its Principles and Criteria (P&C) have continually been revised and strengthened over time
[78], reflecting its progressive nature. Certification is still beneficial in demonstrating a commitment to sustainability and improved branding. Since its inception, approximately 20% of palm oil produced globally is certified sustainable by RSPO
[79].
At a national level, the top-producing countries of Indonesia and Malaysia established Indonesian Sustainable Palm Oil (ISPO) and Malaysian Sustainable Palm Oil (MSPO) in their respective countries. Compared with RSPO, studies consistently found RSPO to be the most robust, comprehensive, and ambitious in criteria, followed by MSPO, and ISPO the least
[76][77][80][81][82]. As such, some studies do not count MSPO and ISPO as certified sustainable palm oil (CSPO)
[2][4][78]. Indirectly, they demonstrate that the stringent nature of RSPO and its high costs make it challenging to attain. Instead, ISPO and MSPO are perceived more as stepping stones for smaller companies and smallholders in the top two producing countries to adopt sustainable practices
[83].
Data and Reporting Platforms
The rise in data and reporting platforms boosts transparency and traceability for the palm oil sector. These platforms include satellite-based deforestation monitoring systems such as the World Resources Institute’s (WRI) Global Forests Watch program
[84], Suitability Mapper
[85], Forest Cover Analyzer
[86], Trase
[87], and RSPO PalmTrace
[88]. These platforms enhance supply chain mapping and enable better planning of land use strategies and sustainable palm oil production.
Moreover, data platforms such as the Zoological Society of London’s (ZSL) Sustainability Policy Transparency Toolkit (SPOTT)
[89] and WWF’s Palm Oil Buyer’s Scorecard
[90] go beyond the requirements of certification to rank companies on their sustainability disclosures over the years. For example, the SPOTT initiative is an annual assessment of soft commodity producers, processors, and traders on the ESG-related public disclosure of their organization, policies, and practices
[89]. They produce separate assessments for palm oil, timber and pulp, and natural rubber. They actively collaborate with industry players including the RSPO
[91] and all members of the value chain—governments, financiers, producers, consumers, investors, and NGOs—to adopt strategic measures to improve the sustainability of palm oil while achieving supply chain transparency
[92]. At its inception in 2014, only large publicly listed companies were initially assessed
[93], as they were perceived to have the largest environmental impact, greater access to resources, and more pressure to improve compared to smaller companies. However, smaller and privately owned companies were subsequently added as stakeholders sought to ensure holistic efforts of transparency in the sector. Smaller companies have shown improvement rates similar to those of larger companies due to increased pressure on the sector throughout SPOTT assessments from 2014 to 2018
[93]. The indicator framework has also been revised and expanded to include indicators beyond “Environmental” considerations to provide a comprehensive scope of ESG, and it is considered to have reached a point of maturity
[93].
3. Integrating Sustainability with Finance
Several studies beyond the palm oil sector find that transparency on ESG can have a relationship with various financial indicators. These relationships conducted across sectors and countries extend support for ESG integration. Common variables such as firm valuation and firm size are studied further to rationalize the relationships. Drawing inspiration from these studies, the literature links back to the palm oil context by reviewing existing research in the sector to identify gaps and opportunities that this reseach can help to address.
Since 1970, over 2000 studies have been conducted
[24] to marry the relationship between the non-financial indicators of sustainability with financial indicators. This demonstrates the push for ESG integration into financial considerations, building the foundations for sustainable investments. However, the findings of prior research have been mixed. There could be significant positive or negative relationships, or no significant relationships. In Friede, Busch, and Bassen’s (2015)
[24] analysis, most studies found a positive relationship between ESG and firms’ financial indicators, a quarter had a neutral relationship, while a tenth reflected a negative relationship. These studies are scoped differently using inconsistent measures for sustainability
[30] as well as financial indicators. Moreover, results were also mixed as to whether total ESG or isolated environmental (E), social (S), or governance (G) components held more weight in determining financial indicators. Isolating the components also helped to remove the effects of netting, as a negative indicator in one component could be negated by a strength in another
[94].
Many studies found a positive relationship between ESG and organizations’ financial indicators
[24][43][95] such as lowered cost of capital, better operational performance, and improved stock price performance and market value. Higher ESG performance inherently protects firms by portraying a positive reputation to shareholders
[41]. An analysis of 52 studies based on 33,878 observations finds that corporate social performance is positively correlated with corporate market value
[26], suggesting that the S component holds more weight. A global study of 44 countries concluded with statistical significance that ESG scores were heterogeneous, where overall ESG scores and E scores had positive effects, while S and G scores had negative effects
[27]. In Germany, a significantly positive relationship was found between ESG and accounting-based firm performance, and G was found to be the strongest determinant factor
[28], possibly due to the German Corporate Governance Code introduced in 2002 where firms are obligated to report CSR. This demonstrates how regulating authorities have a positive influence over companies’ actions. At the industrial level, a study of large manufacturing companies in the US during the 1980s found that those with higher profits tended to be more socially responsible with reduced risk
[96]. Another study on the real estate sector in developed countries found a positive relationship between ESG disclosure with financial performance, where E was also significant in influencing return on capital (ROC)
[29]. As for the pharmaceutical industry in Italy, G was positively related to financial performance
[97], where good corporate behaviours through compensation, management of fraud, ethics and values, transparency, and anti-corruption could be linked with companies’ operations and relative market performance.
Amongst those with neutral relationships, it is possible that the costs of demonstrating ESG were net off by financial benefits
[98][99]. Similarly, no significance was found in another study on Italian blue-chip companies between ESG scores and abnormal returns, evidencing that social responsibility was not a reliable indicator for leverage
[100]. These examples suggest that ESG disclosures have no relevance in determining any financial benefit.
Of those with negative relationships, a study on Northern European firms also found a negative relationship between ESG and P/E
[31], with a weak correlation suggesting that investors interested in ESG were not necessarily concerned with the high returns. In terms of risk, a negative relationship was found between E and S disclosures on total risk, as corporate transparency increased the reputation and trust of stakeholders
[101]. Similarly, the ESG performance of textile and apparel firms helped to reduce volatility and market risk
[102].
As opposed to a linear relationship, Nofsinger, Sulaeman, and Varma’s (2019)
[94] study of E and S components found that institutional investors demonstrated an asymmetric preference for strong and weak CSR attributes. Investment portfolios that avoided or had few weak ES stocks generated higher alphas than those with a greater fraction of weak ES. Institutional investors were averse to ES weaknesses through divestment but appeared ambivalent towards ES strengths because CSR was also linked with agency costs that eroded economic benefit
[94]. This aligns with the findings of Krüger (2015) that the stock market responds weakly negatively to positive ESG news
[103] and that firms with strong CSR records had more liability due to greater scrutiny of negative events
[104]. In this regard, minimizing risk through divestment appeared to dominate investors’ decision-making process.
Amongst the literature review, few studies were conducted on the palm oil sector using other financial indicators. Those conducted on palm oil either had only an environmental focus or were exclusive to RSPO certification rather than overall ESG transparency, which could be reflected in other measures that were more inclusive of smaller firms. For studies with an environmental focus, markets were found to be sensitive to negative environmental events, as the 2015 haze crisis had significantly negative impacts on abnormal stock returns for palm oil companies in Southeast Asia
[34]. Separately, a positive relationship was found between environmental disclosure and return on assets (ROA) for Malaysian companies, which were explained to have a larger firm size than Indonesian companies
[105]. For studies exclusive to RSPO certification, nine Indonesian RSPO-certified companies were found to have a 2.28 times appreciation in share price between 2005 and 2016 compared to uncertified companies
[35]. Climate Advisers also established a palm oil index that found 18 RSPO-certified firms outperforming non-certified counterparts by about 25% over 6.5 years
[36]. Mixed results were observed in another study of 64 palm oil firms, where Malaysian RSPO-certified firms had poorer risk-adjusted performance than their respective non-certified peers, while the Indonesian RSPO-certified portfolio fared better than its peers, implying RSPO had limited influence on stock performance
[37]. Tey and Brindal (2020)
[37] identified that RSPO certification requires economies of scale that are more suited for larger farm operations and that palm oil investors may benefit more from small-cap companies in Malaysia. They also raised the need for an easily understood and accepted ESG framework, as opposed to RSPO certification, to provide a more robust view for developing the basis of investing for growth through a sustainability standard. This spurs further investigation into the palm oil sector that goes beyond certification and assesses overall ESG transparency. It will also respond to Godfrey and Hatch (2007)
[106], who called for industry-specific research, as differences among industries can become obscured when ranked by the same criteria. Comparisons within industries provide more clarity on relevant and meaningful sustainability considerations.
3.1. Firm Valuation
Studies in previous literature have used various financial indicators such as market value, ROA, ROC, P/E, stock returns, and dividend yield. This research will focus on the valuation of a company to be given by P/E because far fewer studies have used P/E, despite it being the top-used measure for valuing companies
[107]. It is calculated as the share price divided by earnings per share. Earnings per share is the net income over a certain period, typically a fiscal year, divided by the total number of shares outstanding at the point in time.
The rationale for using P/E is that investors can apply ESG investing principles to guide their decisions to purchase company shares, which are reflected by the share price. As a ratio, P/E standardizes stocks of different prices and earning levels, making it useful for comparing its performance across time or with competitors in the same industry
[108].
Future value creation is a key component in firm valuation
[109]. It reflects growth, characterized by the size of a company’s investments, the excess investment returns relative to the cost of capital, and the length of time a company can find value-creating investment opportunities
[110]. It is unlikely for a company’s P/E to revert to historically higher levels unless growth prospects and return on incremental capital remain consistent with historic levels, which are difficult to maintain. This explains why stocks with a high P/E are growth stocks that signify overvaluation, as fast growth and high volatility are expected.
Meanwhile, a low P/E represents value stocks, which typically represent companies that have slowed in growth. Value stocks indicate modest expectations of future value creation and, if the company is stable, they can present opportunities for attractive returns. A low P/E could signify undervaluation or that the company has slowed in growth with low volatility. Investors prefer to invest in company stocks with low P/E because it also represents a low price for a high earning, deeming it a value stock with higher returns anticipated
[111]. Therefore, P/E ratios help to identify valuation premiums or discounts, as well as risk and growth opportunities. Studies show that portfolios with low ratios tend to provide abnormal or higher risk-adjusted returns
[112][113][114].
Conversely, high P/E ratios can also be associated with slow growth
[115]. Investors could change perspectives and view investments as less risky, causing demand and hence prices to increase. Such an example was when the COVID-19 virus impacted global economies in 2020, and companies with the highest ESG rankings were found to be trading at a 30% premium relative to poor performers by referencing their forward P/E
[116]. This was due to high capital inflows into ESG funds causing an ESG bubble, suggesting that the P/E values of ESG investments were overvalued. Within the short period from April to June 2020, more than USD 70 billion was poured into ESG equity funds, surpassing annual flows
[40]. Markets viewed ESG funds as less risky than non-ESG funds during COVID-19 when uncertainty was high, and demand for ESG funds grew, raising the P/E despite market conditions which implied slowed growth. Separately, Goldman Sachs Equity Research also hinted at a positive relationship, where global companies highly aligned with the EU Taxonomy were valued at a 37% P/E sector-relative premium, while low carbon-emitting companies in the Asia Pacific were trading at a 28% P/E premium over their high carbon-emitting peers
[71]. Companies being transparent about their sustainability efforts appeared to encourage ESG integration as an innovative strategy for improving their valuation.
The rise of ESG presents many opportunities for sustainable investments. Studies remain inconclusive about the relationship between ESG transparency and P/E. Jitmaneeroj (2018)
[30] found a positive relationship between the governance component and P/E in US companies, as companies focused on corporate governance practices during the 2008–2009 financial crisis and less on environmental and social factors. Almeyda and Darmansyah (2019)
[29] and Junius, Adisurjo, Rijanto, and Adelina (2020)
[117] found no statistical significance between ESG with P/E in the real estate sector and four ASEAN countries, respectively. Meanwhile, Svensson (2020)
[31] found a negative relationship with P/E in Northern Europe companies. Hence, ESG could be suggested to have a neutral, positive, or negative relationship with P/E.
Therefore, by recognizing that ESG performance is linked with providing stakeholders with transparency on high performers, companies with high ESG transparency could have low P/E as they are expected to have higher returns than companies with low ESG transparency. Alternatively, high ESG transparency could also be associated with high demand and hence high P/E, as they are viewed as relatively low risk.
3.2. Firm Size
Firm size is frequently found to be related to firms’ sustainability-related decisions. Larger firms are usually more involved with CSR compared to smaller firms
[118]. Many studies commonly use market capitalization, assets, and revenue as a control variable to control for the effect of size
[28][32][49][53][119]. They imply that larger firms have a greater influence on societal stakeholders (e.g., larger consumer outreach and more employees) and are thus more closely monitored by the public, incentivizing them to better disclose their sustainability efforts
[33][120]. They are also better positioned to reduce regulatory pressures from governments via the legitimacy theory
[121], which explains why some public exchanges have stricter reporting requirements for larger firms. Larger firms are characterized by economies of scale
[122], with more monetary, intellectual, and physical resources available to invest in ESG, and set exemplary models as market leaders
[102]. Larger firms that invest in ESG can thus reduce firm risk, create a positive reputation for the firm, gain stakeholder trust, and gain a competitive advantage. However, the direction of the relationship between firm size, CSR performance, and financial indicators can be positive or negative
[31].
While the benefits outweigh the costs for larger firms, the case is the opposite for smaller firms. ESG disclosure raises the cost of capital for listed small and medium-sized enterprises (SMEs)
[123] as their firm characteristics differ from large firms by having simpler reporting structures, limited financial and human resources, and hence limited sustainability management tools
[124], which changes the effectiveness of ESG disclosure.
To a lesser extent, studies also consider interaction effects between firm size with disclosure to explore firm-level heterogeneity since larger firms have greater propensity to attain better ESG performance. However, the interaction effects were found to be inconclusive. Krueger, Sautner, Tang, and Zhong (2021)
[33] found a negative interaction between firm size and mandatory disclosure, indicating that smaller firms had less availability of ESG reporting, and were thus associated with poorer ESG performance than larger firms. Sánchez-Infante Hernández, Yañez-Araque, and Moreno-García (2020)
[32] found that firm size had a significant moderating effect, where larger firms had stronger relationships between CSR and economic performance. On the other hand, Lin, Cheah, Azali, Ho, and Yip (2019)
[125] had a counterintuitive finding that smaller firms in the automotive industry had higher efficiency with higher green innovation investment returns, and generated more profits than large firms that were too aggressive in investments and had lower financial performance.
As for firm size in the palm oil sector, empirical studies on the moderating role of firm size were not found. However, research finds that larger firms are perceived similarly to have greater propensity and hence expectations to adopt sustainable practices. The 2020 Annual Communication of Progress (ACOP) reports submitted by RSPO members found that the progress of the biggest players across the supply chain is considered too slow, especially for processors and traders, where nine of the ten biggest players were less than 30% certified
[126]. Amongst growers, only three of the top ten achieved at least 80% certification. Companies with the largest land area and volumes of palm oil handled still fell short of certification. These companies are expected to have significant leverage with more responsibility to take up RSPO certification and were called to take urgent action to close the certification gap, as larger players have added responsibility to raise their uptake of sustainable palm oil.
The current literature commonly polarizes palm oil producers as large or small, without distinguishing medium-sized companies or smallholders
[127]. Thus, policies and initiatives rarely target medium-sized companies. They may also lack the capacity to adopt ESG commitments given the numerous frameworks and guidelines for companies to adhere to. Some smaller companies can also have sustainable practices in place that are not incorporated into the policy framework, or they may only sell to the domestic market, and hence do not require an RSPO certification. The MSPO and ISPO certifications and standards such as the SPOTT framework help to be more inclusive toward varying firm sizes, as they look beyond the price premium and stringent criteria associated with RSPO certification to assess companies on their sustainability efforts. Efforts are still needed for more inclusive support toward smaller companies, including strengthening the acceptance for MSPO and ISPO to be recognized by international stakeholders.
3.3. Valuation for Palm Oil Companies
The valuation of palm oil companies was previously found to be positively influenced by economic indicators such as inflation, exchange rates, and the world crude palm oil (CPO) price
[128]. In recent years, however, the correlation between companies’ share prices and CPO prices began to show a disconnect due to rising ESG concerns. The correlation between CPO prices and the Bursa Malaysia Plantation Index, which tracks 43 listed planters, weakened from 0.75 in 2020 to 0.22 in early 2021 when CPO prices rose beyond RM 3500 per tonne
[129]. Similar observations were found between the CPO and the Kuala Lumpur Plantation Index (KLPI) up until August 2021
[130]. The portrayal of weak ESG practices, through the US Customs and Border Protection’s (CBP) ban on FGV Holdings Bhd and Sime Darby Plantation due to the use of forced labor, were cited to have eroded the share price of Malaysian planters. Investors’ growing ESG concerns appear to have overtaken economic indicators in influencing the valuation of palm oil companies. This reaffirms the need for companies to be transparent about ESG efforts for addressing investor concerns to encourage uptake of ESG integration as an innovative sustainable investing strategy.
A descriptive study performed by a global financial institution on 15 palm oil companies in 2021 identified similarly that ESG risks have caused the sector to trade at a record low P/E, which is a 72% discount below peak P/E
[131]. This is wider than other ESG-excluded names in tobacco and thermal coal sectors. In other words, the palm oil sector was valued at a discount despite efforts to improve practices. Even with volatile market movements due to the Russia–Ukraine war and Indonesia’s temporary export ban on palm oil in 2022, another study by Foo
[132] on five palm oil companies in 2022 suggested that the sector was still valued at 13-year lows since the Global Financial Crisis in 2009. This was reaffirmed by Rijk, Miraningrum, and Piotrowski (2022)
[133], who found that Wilmar, the largest company in the palm oil supply chain, reached its lowest P/E in history as of March 2022 due to reputational impacts caused by poor transparency relating to forest and sustainability risks, calling for better transparency of “No Deforestation, No Peat and No Exploitation” (NDPE) policy execution and uptake of certified palm oil. As these studies are mainly descriptive, they inspire an opportunity to conduct empirical research to validate if there is any statistical significance between ESG transparency and the P/E valuation discount of palm oil companies, instead of looking at stock returns or ROA conducted by previous studies.
