1. Introduction
Many organizations worldwide cause contamination of the environment, which has become a concern for researchers and policymakers [
1]. Environmental dilapidation adversely affects living beings and even nonliving beings around. Specifically, in some countries such as Saudi Arabia (KSA), greenhouse gas emissions have increased by 225% since 1990. More specifically, during recent years, KSA produced more than 490 million metric tons of air pollution and has been blamed for contributing 1.47% of greenhouse gases globally each year [
2]. These Hypothesized framework s paint a bleak picture of the country from the perspective of a sustainable future and call for extraordinary measures at each level. Currently, many developing countries vulnerable to changing climatic conditions, as most of its ecosystems are sensitive.
Moreover, the nation has been facing increasing temperatures, floods, and droughts. The country has faced huge natural disasters stemming from environmental disorders [
3]. Hence, there is an urgent need to take emergency measures in order to mitigate this vulnerability.
Industries, including the healthcare sector, have a substantial impact on the environment as they contribute to environmental issues such as climate change [
4], waste [
5], deforestation [
6], and water and air pollution [
7]. In this regard, hospitals particularly emit hazardous pollutants of various classes, potentially causing several diseases, including, among others, lung cancer. The release of chemical and other types of pollutants through hospital waste to the environment without scientifically managing it creates critical environmental issues and potentially causes dangerous diseases. In return, even hospitals themselves become vulnerable to adversities of this kind of environment, which negatively affects hospital performance by endangering patients’ lives and affecting treatment processes.
In order to mitigate environmental deterioration, organizations need to work to reduce their environmental footprint. Consequently, researchers around the world started introducing concepts, such as green human resource management [
8], green organizational performance [
9], green marketing [
10], and green change [
11]. Since tendencies and definitions of organizational success are changing, it is not enough to earn profits for survival and growth, but it becomes imperative for modern organizations to contribute to the environment positively [
12].
As industries are creating life-threatening pollution on earth, they must play a vital role in controlling it. This is why corporations in the current era are under immense pressure from different stakeholders (customers, employees, the public, or even the shareholders) to improve their environmental footprint and stewardship [
13]. Whereas efforts to reduce environmental dilapidation at government levels occur in several states, the striking observation of different scholars is that such efforts will be unsuccessful without improving the individual behavior towards the environment [
14,
15,
16]. Thus, promoting the pro-environmental behavior among employees of a corporation is of utmost importance for a corporation to improve its overall environmental footprint. Therefore, one of the primary objectives of the current study is to explore the factors that can improve the pro-environmental behavior of employees.
Wang et al. [
17] revealed an immense increase in the levels of greenhouse gases and CO
2 emissions in recent years. Concerns about economic growth, environment, and social interaction are not new, but the pressure on organizations to act in a socially responsible manner is increasing faster than ever before [
18]. Meanwhile, the importance of corporate social responsibility (CSR) has increased the need to conduct activities differently by integrating the community’s issues and activities in a targeted, socially responsible, and economical way [
19]. Researchers have shown a severe concern for CSR, which is considered one of the most important phenomena for modern enterprises from the perspective of environment management [
20,
21]. Firms have the right to sell goods or services to consumers, but they are also responsible for conducting their activities in a socially responsible manner.
Corporate social responsibility generally includes philanthropy, environment conservation, diversity and labor practices, and volunteerism. However, in the context of the healthcare sector, the potential role of CSR to mitigate the environmental footprint of a hospital is not well-explored. In a healthcare context, CSR activities were directed on charity and welfare-related activities such as free treatment, including free or subsidized surgeries, lab tests and investigations, surgical equipment, medicines, and even food and accommodation to patients [
22,
23]. Though there have been a few recent studies from the healthcare sector [
21,
24] to propose CSR as an enabler to improve the environmental footprint of a hospital, such studies are sparse, implying that more research is required to explore the importance of CSR from the perspective of environmental management. Therefore, another objective of the current study is to investigate the relationship between CSR and employees’ pro-environmental behavior.
Recently, scholars have acknowledged the importance of ethical leadership to shape employees’ behavior. In particular, it has been reported that an ethical leader is likely to influence the discretionary behavior (not formally required for a job) of an employee [
25,
26]. Specifically, there exists a positive relationship between ethical leadership and employees’ pro-environmental behavior. More specifically, in some recent studies, the mediating role of a leader to spur employees’ discretionary behavior has been reported [
27]. In the current context, the pro-environmental behavior of an employee is also a discretionary behavior; therefore, it will be interesting to investigate the mediating role of an ethical leader between the relationship of CSR and employees’ pro-environmental behavior. Thus, investigating this mediation effect is another important objective of the current research.
According to the social role theory [
28], several scholars have concluded that gender differences in attitudes and behaviors will continue to emerge in different settings and cultures. Common sense suggests that women focus more on the role of a guardian than men and are interested in learning and nurturing social behaviors, such as helping and caring for their colleagues [
29,
30]. In the current context, the role of female leaders to transfuse pro-environmental behavior among employees has a high significance. Hence, the last objective of the current study is to explore the moderating role of a female leader in the above-proposed relationships.
The proposed framework of the current study was applied in the healthcare sector. This sector was considered relevant to serve the purpose of the current survey due to the following specific reasons. First, as stated earlier, hospitals are a significant pollutant. In the case of developing countries, hospitals are blamed for producing a large amount of solid waste, including plastic, glass, metal, food, and others [
31]. Unfortunately, this waste ends up in landfills without any recycling. Therefore, the promotion of environment-specific behavior among hospital employees may be helpful in reducing this level of environmental dilapidation on the part of hospitals.
Yet, another reason for choosing the healthcare sector was the considerable presence of females. Given that females almost constitute half of the country’s population [
32], their contribution to employment is just above 30% [
33]. Moreover, healthcare and teaching are the only two sectors with a significant female contribution in the country. Thus, the consideration of female leadership to spur pro-environmental behavior among employees in the healthcare sector will be of prime importance from the perspective of environmental management for emerging economy.
The present research is an action with three definite contributions to the available literature. Firstly, the current study attempts to project CSR beyond the charity domain to improve an organization’s environmental footprint. In this regard, a majority of previous studies on CSR were conducted from a philanthropic orientation, including providing some temporary relief to deprived individuals [
34,
35]. The current study attempts to create an understating that CSR is a mechanism that can be employed for specific sustainable outcomes, including environmental well-being.
Secondly, CSR is viewed as a macro or institutional level phenomenon, and less attention is paid to individual involvement in CSR. In this study, it is believed that behaving in a socially responsible manner at an employee or individual level can yield equal or more achievements than at the macro level. This is more relevant to the population because more environmental issues arise due to individual-level carelessness. Thirdly, unlike other industries, hospitals are organizations with significant female participation. We highlight the existence of a gender role difference, and that the above-mentioned gender differences influence the realization of environmental objectives. Thus, the focus of the present research is to explain whether environmental issues can be managed using CSR activities.
The remainder of the current study is composed of four different sections. For example, the next section deals with related theories and literature to frame different hypotheses. It is followed by the methodology section, in which the authors have discussed the issues related to sample and data collection procedures, followed by the result section, which deals with the analysis of the data by employing different statistical tests. The last section belongs to the discussion, implications, and conclusion of the current survey.
5. Discussion
There were four major objectives to carry out in the current study. Firstly, the study intended to investigate the factors that influence the pro-environmental behavior of employees in the healthcare sector of developing countiries. To this end, the current study’s findings bring to the fore that CSR perception of employees about their organization supported by ethical leadership can spur the discretionary behavior (pro-environmental) of employees. Such findings are also in line with prior studies [
97,
139]. The survey respondents confirmed that they are self-motivated to participate in different environment-specific activities at the workplace in response to the CSR commitment of their organization and the ethical conduct of their management. Secondly, the study attempts to extend the discussion on CSR from the perspective of environmental management. To this extent, the findings supported that CSR perception of employees working in different socially responsible hospitals can inculcate in employees’ positive feelings about their organization. These results can also be explained in light of the social exchange theory. As stated earlier, the individuals are expected to continue a social relationship with others by exchanging the benefits received from others with benefits. In this regard, when employees observe the CSR orientation of their socially responsible organization for society and the environment, they take such participation of an organization as a benefit for society, the environment, and the employees. In response, they feel the motivation to exchange this benefit (CSR) received by their organization, with a benefit. Thus, they become more pro-social at the workplace and willingly take part in different environment-specific activities to support their organization to preserve nature. Specifically, as CSR engagement of an organization is assumed as a discretionary commitment of an organization for all stakeholders, this discretionary commitment is exchanged by the employees (a key stakeholder) by their engagement into certain discretionary tasks. Among these, their pro-environmental behavior is also discretionary behavior. These findings were also supported in the seminal work of Glavas [
140] and Jones et al. [
141].
Thirdly, the current study also highlights an ethical leader’s importance in explaining the association between CSR and employees’ pro-environmental behavior. In this regard, as per the findings of the current analysis, it was observed that in the presence of ethical leadership, the followers extend their environmental commitment to a further level. Especially when they observe that their leader is an advocate of ethicality at the workplace, they copy the ethical conduct of the leader as a role model. Hence, these processes help them to shape their ethical behavior at the workplace. Generally, a relationship of CSR and employees’ positive behavior (pro-environmental behavior in the current case) exists; however, in the presence of an ethical leader, this relationship provides an added explanation to the employees to participate in different environment-specific behaviors. More importantly, an ethical leader communicates to the follower about their importance to improve the overall environmental footprint of their organization through the voluntary engagement of the employees. To this end, the study confirms the mediation role of an ethical leader to explain a positive association between CSR and employees’ pro-environmental behavior. Recently, some other scholars have also mentioned the mediating effect of leadership to explain the discretionary behavior of employees [
142,
143].
Fourthly, another important objective of the current analysis was to discuss the role of gender difference for the indirect relationship of CSR and employees’ pro-environmental behavior. Specifically, the current study intends to highlight the moderating role of a female leader to better support the above-stated indirect relationship. As per the findings of the current analysis, it was observed that both male and female leadership moderate the indirect relationship of CSR and pro-environmental behavior. However, the case of a female leader is well-differentiated from the case of male leaders, as in the presence of a female leader, the indirect relationship of CSR and employees’ pro-environmental behavior is stronger than male leaders. Generally, the prior literature also regards females’ important role in preserving the environment [
117,
118,
144]. Recently, developing country like KSA has witnessed significant changes, and the role of females in different management and leadership positions in public spheres was brought to the fore [
115]. Moreover, the current regime led by King Salman has witnessed significant social reforms to empower females in the country. This is why females now capture a better representation for leadership positions than in the past [
116], implying that there is a paradigm shift in the culture of KSA to empower females and realize their leadership potential in the corporate world. Additionally, the theory of social role also supports this concern of females for the environment. More specifically, the scholars regard the correspondent inferences that females are more caring individuals [
145]. Moreover, individuals carry out specific gender roles as they enact specific social roles. Socialization is a mere facilitator for such gender-oriented role performances [
146]. Thus, the role of female leaders is more important for infusing pro-environmental behavior among employees than male leaders.
5.1. Implications
5.1.1. Implications for Theory
From a theoretical point of view, the current study enriches the literature on organizational management and CSR in three ways. In the first place, the current study enriches the literature on CSR from the perspective of employees. In this regard, most of the current literature assumes CSR from the perspective of organizational outcomes, including organizational performance [
54,
82] or organizational reputation [
49]. Knowing the potential benefits of CSR at the level of employees is more important, especially from the perspective of environmental management. However, such contributions in the literature are relatively sparse. The current study is an attempt against this backdrop.
In the second place, the current study also stresses the mediating role of ethical leadership to better explain the relationship between CSR and pro-environmental behavior. In this regard, very few studies have attempted to investigate the mediating effect of a leadership style to shape the behavior of employees. To our knowledge, only the studies of Molnár et al. [
21] and Murtaza et al. [
27] have followed a similar approach. Nonetheless, many studies have highlighted the direct importance of a leadership style, especially an ethical style of leadership, to spur employees’ pro-environmental behavior [
81,
88]. However, the academic debate has paid relatively little attention to the potential mediating effect of ethical leadership on employees’ discretionary behavior.
Finally, and most importantly, the current study highlights the important role of gender, especially the role of a female leader, to spur the indirect relationship of CSR and employees’ pro-environmental behavior. Although there have been different studies highlighting the importance of females to protect the environment [
108,
117], few studies have analyzed the concept in the context of a patriarchal culture. Thus, the current study is one of the few that attempts to highlight the important role of females for better management of the environment.
5.1.2. Implications for Practice
The current study has some critical practical implications for the healthcare industry. First of all, the current study highlights the importance of CSR engagement in a hospital from the perspective of environmental management. As the findings of the current study unveiled, the CSR perception of hospital employees plays an important role in shaping their eco-friendly behavior. Realizing this fact, this is the time for the policymakers of this sector to reframe the strategic intent of CSR as the current state of CSR affairs in most hospitals is related to charity and donations that cannot help a hospital improve its environmental footprint. A hospital needs to understand the potential benefit of CSR to address the natural environment. In this regard, the Kingdom of Saudi Arabia can benefit from the example of the nations of the EU, which were able to improve their natural environment by promoting its importance on an individual level. Due to such initiatives of the EU, individuals recognize their important role in improving the environment, which is perhaps why the sustainability index of most EU countries improves each year.
Secondly, the current study also highlights the importance of an ethical leader for a hospital. In this regard, it is important to mention here that only the CSR engagement of an organization is not enough. The presence of responsible management is a necessary precondition to achieve the expected outcomes for a hospital. Moreover, an ethical leader further highlights the importance of the individual to improve nature and the environment. Especially in the context of sustainability management, the presence of an ethical leader makes their role toward environmental improvement clear to every employee. There is a dire need to promote such an ethical leadership style in the healthcare sector to address environmental dilapidation effectively.
Lastly, as stated earlier, females are almost half of the population of the kingdom. However, unfortunately, their role in most social development programs is very passive. Given that the KSA is a society characterized by a patriarchal culture, the participation of females in society-building activities is not encouraged. To this end, the results of the current study may be eye-opening for this society to understand that without effective participation on the part of females, it is less likely for the kingdom to achieve its expected sustainability outcomes. Though the government has recently shown seriousness in reducing its carbon footprint, if half of the population remains passive, achieving such objectives will remain a difficult task. Moreover, in light of the findings of this analysis, it is important to promote females in more managerial posts to shape the behavior of a workforce better. Surprisingly, females’ role in the environment did not receive any significant attention in past studies. Moreover, as mentioned by Byun and Al-Shammari [
147], the age of female leaders and the power of the CEO can influence the ethical behavior of a female leader, and this context needs to be further explored.
5.2. Limitations and Future Research Directions
Even though the current analysis brings to the fore some important implications for the healthcare sector, the study also encounters some important limitations. First of all, the study sample was only limited to three specific cities of one country. Thus, the geographic concentration may limit the generalizability of the current analysis. In this respect, future researchers should include more cities and provinces to make a better and generalizable impact. Secondly, the study only records the perceptual measures of CSR. Although such measures are considered helpful by a plethora of studies, using an objective measure of such constructs in the upcoming studies may generate more realistic outcomes.
Similarly, the current study’s findings may remain limited in its scope because a cross-sectional survey design was employed, limiting the causality of association among different constructs. In this regard, a better approach in future studies may be to incorporate a longitudinal data design. Moreover, given that CSR is context- and culture-specific, the current survey findings may remain the same for similar cultures (UAE, Oman, Qatar, etc.). However, in different cultures, due care is necessary before interpreting the current survey results. Lastly, it would be interesting for future researchers to explore whether the age of the female leaders (early in their career vs. late in their career) or CEO power (which either enables or hinders the influence of the leader) may have a differential impact on the ethical behavior of the female leader.
