Corporate environmental disclosure could be described as a disclosure made by a firm to the stakeholders concerning its externalities discharged and measures taken to mitigate the negative effect caused by the company. The major policy that responsible of controlling global climate changes is the ability of the firms to manage their energy consumed and quantify the carbon emissions discharges by considering grants and exchanging carbon in the market (Al-qahtani & Elgharbawy, 2019lıç & Kuzey 2018). Energy is being required (such as light, heat, mechanical, sound, electrical and chemical energy) by firms to operate and run their day-to-day activities (Fakoya & Nakeng, 2019). Almost all firms consume energy in various manner depending on the nature of its operations. Energy can be described as self-generated when it is being generated from sources other than natural such as hydro, solar and wind. It can equally be generated using non-renewable sources that is using natural sources. Under this category, firms normally consumed petroleum, natural gas and coal as sources of generating non-renewable energy for their operations.
To utilize energy efficiently, it is essential for a firm to select renewable energy sources for combating present and future climate change and for mitigating overall environmental effect in the society (GRI, 2021). Though, improvement on energy transition in a country is determined by the level to which a strong enabling environment is being created. This comprises political will, flexible polices, conducive business atmosphere, incentives for investments and innovation, consumer awareness and protection agencies, pressure groups and adoption of new technologies among others (World Economic Forum, 2021).
However, environmental calamities in relation to air pollution as a result of consuming non-renewable energy can be controlled when firms utilize and disclose measures used in curtailing harms produced by the energy consumed in the country and ensure full compliance with established laws.
Corporate organization need to operate legitimately within the community. Therefore, from the perspective of a corporate entity, legitimacy is the general notion that the activities of the companies are appropriate or suitable within some socially built system of norms, standards, ethics and beliefs (Emeka-Nwokeji, N.A and Okeke, 2018). As a result of the connection between the legitimacy of a firms and the perception of the society about the firm, it is imperative that management makes disclosures that will positively influence the opinion of the society about the firm (Cormier & Magnan, 2013). Therefore, legitimacy theory is essential to the present study since operation of firms could only consider legitimate if firms ensure that their operations are coherent with the expectations of the society in which it operate. Hence corporate board attributes are capable of ensuring firms energy disclosure and operate accordance with community expectation.
Corporate board independence and energy disclosure
Board independence is one of the board characteristic that could have an influence on energy disclosure. Board independence is considered as one among the most influential and relevant corporate governance instrument for monitoring and regulating the management team and for protecting stakeholders' interests (Ezhilarasi & Kabra, 2017). Independence of directors used as an independent power in resolving internal dispute within the management on behalf of the common shareholders of the company (Fama & Jensen, 1983). The existence of sufficient number of independent board member on the board has been perceived as key for preserving the interest of all types of stakeholders (Mallin et al., 2015) and confirm that firm decision are made in a way that safeguard the concern of all stakeholders (Lo, Wong, & Firth, 2010). Based on agency theory, many studies have documented that presence and competency of independent directors on the board defend the interest of all shareholders (Lo et al., 2010; Mallin et al., 2015). Prior researchers have established positive relationship between number of independent directors and the corporate disclosure performance (Chen & Jaggi, 2001; Ferreira, Ferreira, & Raposo, 2011; Patelli & Prencipe, 2007). Baalouch, Ayadi and Hussainey (2019) investigate the determinant of environmental disclosure quality in French. The study variables focus on issues related to the policy and vision of independence board member and gender diversity on factors associated to the environmental performance. The study revealed that independence of board plays an important roles in explaining disparities in quality of environmental disclosure. Furthermore, studies such as Ikhenade, (2020), Kanashiro, (2020) and Tseng et al., (2020) document substantial positive relationship between board independence and environmental disclosure.
Conversely, Kilincarslan, Elmagrhi and Li (2020) examine the effect of corporate governance structures on environmental disclosure performs. The results reveal that board independence has a negative relation with environmental performance. Other prior studies (see Eriabie, Sylvester Odia, 2018; Rezaee, 2019) fail to document statistical association between independence of board and environmental disclosure. Based on these above, the study hypothesizes that:
H1: There is a positive relationship between board independence and energy disclosure in Nigeria
Corporate board meeting and energy disclosure
Based on agency theory board that has high frequency number of meetings has higher effective advisory and monitoring role on the management. Board activities measured by board meeting frequency is an essential measurement of board actions which helps to overcome agency conflicts (Ofoegbu et al., 2018; Saleh et al., 2020).
In assessing the impact of board meeting on environmental disclosure, Koji, Adhikary and Tram (2020) express that frequent board meeting plays an important role in enhancing disclosure performance of a company, since it assists in reducing the information gap among the board members.
Shahbaz, Karaman, Kilic and Uyar (2020) investigate the relationship between board attributes and corporate CSR commitment as well as between CSR engagement and corporate performance in the universal energy sector. The results specified that board meeting attendance is significantly associated with ESC. Similarly, Khaireddine (2020) explores the influence of board governance attributes on environmental and ethics disclosure in Tunisia. The result reveal that board meeting has a positive and significant effect on environmental and ethics disclosure. Many studies, (Grace Ofoegbu, Odoemelam and Okafor, 2018) have documented a significant positive association with environmental disclosure. In line with the above, this study hypothesizes that:
H 2 : There is a positive relationship between board meeting and energy in Nigeria
Corporate board size and energy disclosure
Board size represents the number of directors on the corporate board. Thus, larger board is likely to comprise more skilled and knowledgeable directors who could have a better skill in managing environmental challenges. In addition, Okpala and Iredele (2019) are of the view that larger board is described by more qualified and knowledgeable individuals with interest on environmental disclosure and effective reporting skills. This indicates that large boards combined a higher quantity of experiences and qualifications, which stimuluses the process of environmental disclosure and helps reduce the anomaly of information and conflicts of interests among the concerned stakeholders. Building on agency theory, the principal (owners) will install a large board to monitor the actions of their agents (Jaskiewicz & Klein, 2007). Board adequacy has been found to have positive influence on firm general activities including frequency of RPTs and general corporate disclosure level (Coles et al., 2008; Michelon & Parbonetti, 2012). in Latin America Husted and Sousa-Filho (2019) investigate the relationship between board structure and ESG disclosure. The result indicates that board size has significantly effects the ESG disclosure. In Nigeria Emmanuel and Teddy (2019) examined the effect of corporate diversity on corporate social environmental disclosure of quoted manufacturing companies. The study reveals that board size has a significant positive influence on the degree of corporate social environmental disclosure of the sampled companies. Furthermore, Ikhenade (2020) found that board size has a positive and significant relationship on environmental disclosure. In the same direction (Khaireddine, 2020; Tseng et al., 2020) establish a positive association between board size and environmental disclosure. Conversely, studies such as Aliyu, (2018) and Odewale, (2020) fail to establish relationship between board size and environmental disclosure. Therefore, based on the above, the study hypothesizes that:
H3: There is a positive relationship between board size and energy disclosure in Nigeria
Corporate board gender diversity and energy disclosure
Gender refers to a description of femininity or masculinity of a person. However, most literature on gender diversity relate the concept to presence, representation and percentage of women on boards of corporations. In recent times, several studies on board personality and group dynamics tend to study the influence of gender on corporate decisions with some of these studies viewing at gender diversity of board attribute and its influence on the role environmental disclosure (Atif et al., 2020; Beji et al., 2020; Ofoegbu & Odoemelam, 2018; Reguera-alvarado & Bravo-urquiza, 2020). Female board members normally find decision much simpler on how to improve their firms’ environmental reporting and are expected to give more ideas on decisions relation to energy disclosure (Ofoegbu et al., 2018).
Tingbani et al. (2020) document a proof for a strong positive association between GHG voluntary disclosures and gender diversity, this creates an important input to the current debate about the role of female directors on the corporate boards. Similarly, Al-qahtani and Elgharbawy (2019) evaluate the extent to which board diversity affect firms voluntarily disclose and management of greenhouse gas (GHG) information in U.K. The results show that representation of female directors in the board of directors positively influences disclosure and management of GHG information. Similarly, Qureshi, Kirkerud and Theresa (2019) documented that firms with higher female representation on their boards present significantly superior environmental, social, and governance performance. Haque and John (2020) investigate how board gender diversity is associated with biodiversity disclosures of a firm, and whether the Global Reporting Initiative (GRI) and the EU biodiversity. The results disclose that board gender diversity is positively related with the biodiversity disclosure.
To sum up the above studies, it was established that having women on the board increases the reporting quality of social decisions and improves the implementation of environmental policies globally.
In contrast, some studies such as Fernandes et al., (2018) and Manita et al., (2018) provide evidence that corporate gender diversity plays insignificant role in implementing environmental policies due to gender-biased influences. Based on these findings, the study hypothesizes that:
H4: There is a positive relationship between board gender and energy disclosure in Nigeria
Corporate managerial ownership and energy disclosure
Jensen and Meckling, (1976) recommend that agency problem can be mitigated through high portion of managerial ownership. This is because, the higher the managerial ownership, the more their personal interest is aligned with that of the shareholders. Shleifer and Vishny (1986) demonstrate the importance of having large shareholders in public corporations to perform monitoring function and reduce managerial opportunistic behavior.
The level of managerial ownership can serve as a way of aligning the interests of managers with those of shareholders, and thereby leading to an increase in the level of disclosure. Previous literature document that directors with corporate shareholding tend to make more environmental decisions to demonstrate their contribution to societal and environmental issues, and to gain different stakeholders’ attentions (Gyapong et al., 2019; Kao, Hodgkinson and Jaafar, 2019). Furthermore, directors who possess certain interest in the firms take environment challenges serious as they may be influenced by institutions, activist groups, and governments towards compliance with environmental regulations. Hence, they are likely to disclose more CSR and environmental information to mitigate political costs (Saini & Singhania, 2019).
Though there are limited studies on managerial ownership and environmental disclosure, some of these studies established that directors’ larger shareholding inspires them to exercise more control for their own financial benefits and interests, rather than to maximize shareholder’s wealth (Alfariz & Widiastuti, 2021; Zaid et al., 2020). Budiharta (2020) investigates the effect of managerial ownership on carbon emission disclosure in Indonesia. The results indicate that managerial ownership positively influence carbon emission disclosure.
In contrast, Giannarakis et al. (2018) establish a significant negative relationship between managerial ownership and CSR in European companies. This shows that managers are not fascinated in providing more disclosure on environmental issues, as this negatively affects their compensation and benefits. Many studies have established negative relationship between management ownership and CSR disclosure. Therefore, based on these findings, the study hypothesizes that:
H 5 : There is a positive relationship between board ownership and energy in Nigeria
Board attributes, Institutional strength and energy disclosure
Institutional strength consists of a set of formal and written rules about two main dimensions of stability/safeguards that seek to guarantee the durability of these institutions and the extent to which these rules are followed in institutional practice. Institutional strength may be conceptualized along two dimensions: enforcement and stability (Levitsky & Murillo, 2009). According to Levitsky and Murillo, enforcement is the degree to which parchment rules are complied with in practice. Where all relevant actors in a given territory routinely comply with parchment rules or face a high risk of punishment, enforcement is high. On the other hand, institutions are stable to the degree that they survive not only the passage of time but also changes in the conditions. Institutions themselves vary in stability and enforcement. For example, laws against prostitution, euthanasia, and the hiring of undocumented immigrants tend to be weakly enforced even in countries with effective legal systems (Van Oenen, 2001). Weakly enforced institutions may be created intentionally or unintentionally. Many institutions are weak because the actors who create them do not intend to enforce them. Thus, one impetus for the emergence of weakly enforced institutions is a divergence between political actors’ real and publicly stated goals (Levitsky & Murillo, 2009).
Government and citizen engagement in environmental and sustainable development public policy is reflected in the extent to which institutions that manage and regulate the operations for the betterment of environment exist and function properly at the national or subnational levels (FDES, 2013). Based on the institutional theory, firms employ many mechanisms to create and maintain sound institutional legitimacy (Meyer & Rowan, 1977). These mechanisms include among others proper means of communication with outside environment. DiMaggio and Powell (1983) suggest that firms can compete favorably in modern environment only if they adopt institutional isomorphism. Institutional isomorphisms are the forces that make organizations to embrace similar environmental conditions (such as Global Reporting Initiatives (GRI) standards for reporting environmental issues). They argue that the process take place through one or a combination of coercive, mimetic or normative pressures. Regulators and other external parties use coersive isomophia to compel the firm to disclose certain information for public consumption. Listed firms are required to comply with mandatory disclosure requirements in totality, and anything in short of that can be sanction by appropriate regulatory bodies (Houqe et al., 2012; La Porta et al., 2006). However, Tsalavoutas (2011), and Yeoh (2005) have argued that existence of regulatory bodies cannot guarantee compliance.
As earlier discussed, previous studies have documented mixed results on the relationship between board attributes and environmental disclosure. It is expected that the mixed findings was a result of the degree of strengthens (i.e the enforcement and stability) of monitoring institutions. Hence, this study hypothesizes that:
H6 a : Institutional strength moderates the relationship between board independence and energy in Nigeria
H6b: Institutional strength moderates the relationship between board meeting and energy in Nigeria
H6c: Institutional strength moderates the relationship between board size and energy in Nigeria
H6d: Institutional strength moderates the relationship between board gender and energy in Nigeria
H6e: Institutional strength moderates the relationship between board ownership and energy in Nigeria
