Cultivating PEB can benefit firms strategically by increasing efficiency, increasing income, improving brand perception, achieving sustainability goals, and giving them an edge over its competitors
[2][8]. Nonetheless, both academics and practitioners have neglected the topic of employee PEB. Employees’ pro-environmental conduct is defined as their desire to participate in environmental engagement
[40][35]. One of the major predictors of employee PEB is the leadership style in a business, according to past research studies
[20,26,41][13][20][36].
2.2. Green Servant Leadership and Pro-Environmental Behaviour
The focus and the centre of attention for servant leadership is the employees’ interest
[1[7][37],
42], directing them in a way to pursue their needs
[43][38], and carrying out different activities that exhibit him/her as a role model of compassionate, altruistic love and empathy
[1][7]. Servant leadership has received much attention from scholars regarding its impact on various aspects of organizational, group, and individual outcomes
[1][7].
Very few studies have focused the environmental concerns and issues and their relation to servant leadership
[2,35][8][29]. Luu Trong Tuan’s
[31][25] idea of integrating the environmental component with servant leadership in the literature says that PEB should serve as an example of humility, sincerity, interpersonal acceptance, and stewardship toward employees’ pro-environmental accomplishments. It should also give advice, help people become pro-environmental citizens, and encourage this kind of behaviour in others. This reflects the pro-environmental approach of the leaders, which can be termed as green leadership. Thus, this study takes this concept as GSL
[1,35][7][29].
In addition to that, the various concepts of green practices, particularly green human resource management (GHRM) practices, are also part of the organizational initiatives, and to implement green practices properly, the role of leaders is critical, and plays an integral part in impacting the organization and employees
[5][39]. Furthermore, Robertson and Barling
[44][40] advocated that servant leadership is significant in promoting PEB, and after the article appeared, most of the researchers turned to investigating the servant leadership in the context to the environment, which is now referred to as GSL
[1,12,35][1][7][29].
PEB is reflected in the positive initiatives of the employees with respect to energy, material, nature, and ecosystem
[38,45][32][41]. Further, it is discussed in the literature as behaviour that is reflected in terms of reuse, recycling, and conservation of the energy
[46][42]. Employees who are directed for PEB benefit the organizational performance directly and indirectly
[1,2][7][8]. The concepts of GSL and PEB are taken and linked from the perspective of SLT
[47][43]. The green philosophy paves the way for the implementation of such practices, which opens the venue to cultivate and develop green values in employees through leadership
[35][29].
2.3. Mediating Role of Environmental Passion
EP is investigated and linked with environmental issues
[28][22]. EP is considered as the motivational state related to the environment. Passion is referred to as the state where employees dedicate themselves in a way to pursue certain tasks and activities persistently
[48][44]. Studies have advocated that such a source of pursuing dedication be utilized by the organization to maximize the organizational performance
[49][45]. When such emotions are directed towards environmentally friendly practices, they develop a state of EP in which they care about the environment and redirect their behaviour towards environmental conservation practices
[25,50][19][46].
GLS attracts employees to work voluntarily, and is friendly towards the environment
[1][7]. The purpose of GSL is to inculcate the emotions in employees towards environmentally friendly practices
[51][47]. Furthermore, it follows the directions of the philosophical perspective from SLT that followers tend to follow leaders and reciprocate through their behaviour and actions. Based on the above argument, it can be referred to as GSL leading employees towards environmentally friendly practices
[31][25]. Furthermore, transformational leadership behaviours, whether verbal or nonverbal, emphasizing environmental issues can be viewed as affective events that are essential for igniting the EP of subordinates
[15,20][4][13].
Additionally, by displaying protection of the environment, environmentally focused transformational leaders can show employees the organization’s commitment and conviction, potentially raising their positive emotional anticipation of environmental operations
[52][48]. In addition to that, environmentally focused transformational leaders who exhibit high levels of idealized influence and intellectual stimulation encourage people to find creative solutions to environmental problems and direct staff to put organizational social responsibility and environmental sustainability ahead of their own self-interests, increasing staff’s intrinsic motivation to participate in environmental protection activities
[20,53][13][49].
Environmentally focused transformational leaders who display interactive processes (such as compassion and mentoring) for their employees to be more receptive to their leadership’s guidance on environmental issues and to participate in environmental protection activities should also make them feel effective and practical support
[54][50]. Employees are much less likely to demonstrate a passion for environmental issues if they have limited opportunities to observe or support environmentally beneficial actions exhibited by their leaders
[20,29][13][23]. A study found a relationship between transformational leadership and EP
[15][4]. Similarly, other studies also found that other types of leadership impact EP
[25,50,55][19][46][51]. GSL promotes employees’ behaviour to serve the organization as well as the community through environmental practices
[56][52]. The aim of GSL is to develop the emotional state in which employees always want to protect the environment while using fewer resources and less energy and adopting recycling practices
[35][29]. GSL exhibits PEB, which in turn influences the employees in a way to develop behaviour that cares for the environment
[2,25,35][8][19][29]. Most studies investigated the mediating role of EP between other styles of leadership on PEB
[15,20][4][13].
2.4. Mediating Role of Climate for Green Creativity
CFGC is referred to as organizational support to employees to carry out their activities in a way in which they work in a creative manner
[28][22]. CFGC reflects on an environment where employees are treated and rewarded based on their creative manner to use fewer resources and new initiatives to solve problems and adopt environmentally friendly behaviour
[32][26]. Moreover, CFGC is considering the utilization of organizational resources and providing support for green creativity, and is involved constantly in developing new insights regarding green change, green practices, green initiatives, and reward systems to employees accordingly for their green creative work-related outcomes
[25][19]. Moreover, the allocation of financial resources by the organization for green projects and initiatives is referred to as CFGC. It has been argued that the values of a green environment convey to employees the need for them to act sustainably
[57][53]. By giving employees the social resources, they require a setting that encourages innovation in the green movement, values, and pro-environmental perception to be merged, which may motivate employees to channel their pro-environmental resources into green work-related behaviours
[28][22].
The role of GSL is very important for cultivating a green environment for employees. Employees have a greater tendency to positively perceive CFGC when environmentally friendly leaders invest in creating it through the provision of adequate green resources, and as a result, they are more likely to display PEB
[28][22]. There are various reasons why this study has focused on GSL as leadership style. First, GSL is regarded as the architecture of the organization that cultivates and supports CFGC
[33][27]. In addition to that, they encourage and reward the employees for green creativity
[31[25][54],
58], and give them the opportunity to solve problems in their own creative manner, and embed this in the culture of the organization
[59][55]. Another reason is that GSL develops the organizational environment in a way in which employees feel free to develop and share their ideas and perform experiments regardless of the success or failure of the idea because they feel support from GSL for green creativity
[58,60][54][56].
Although some efforts have been made to investigate the role of a green climate as a mediating factor between environmentally conscious servant leadership and green performance
[22][16], the role of a green climate as a mediating factor for green creativity in the hospitality sector has not yet been investigated
[28,30][22][24]. Moreover, in general, the literature on green workplaces argues that employees’ views of a workplace’s green environment might influence their attitudes and behaviours
[61,62][57][58]. Another reason is that by giving discretion to employees to utilize resources in a way in which employees feel empowered, and ultimately develop feelings that employees are given resources and empowerment to transfer resources the way they want for green creativity, such decisions reflect CFGC. SLT also advocates the same: that employees tend to follow their leaders’ actions, and environmentally friendly practices performed by leaders are like catalysts to boost their confidence level and lead them to exhibit support and care for organizational CFGC.
2.5 Summary
First, promoting green practices requires GSL. To successfully implement eco-initiatives, PEB, and green interests, SME administration needs to cultivate an environmentally oriented leadership mindset among their managers and overall management. Followers genuinely embrace their leader’s environmental concern, and need to be motivated by their own passion for the cause. This inner drive will compel them to exhibit PEB, both in the presence of their leader and even when they are distant from them
[25][19]. At the organizational level, firms can greatly benefit from the study’s findings; multiple training programmes and effective planning procedures can achieve this milestone. Moreover, the adoption of GSL should link PEB both within and outside the workplace. Organizations are encouraged to provide training to their managers to learn the principles of GSL, enabling them to actively promote PEB
[81][59]. The administration of SMEs should also give special consideration to pro-environmental issues in its hiring and recruitment practices for managers and leaders
[28][22]. To ensure the success of GSL, appropriate reward systems must also be put in place
[32][26]. Second, to encourage pro-environmental actions such as EP and CFGC for the environment, SME management must foster green values among followers through mentoring and training. Third, studies emphasize the significance of creating and maintaining CFGC to promote environmentally friendly behaviour
[22][16].
