1. Introduction
Ethical consumption is very important to create the basis for a green productive society and ethical human life development [
1]. In recent times, environmental challenges related to ecological resources have been gaining interest, and firms are facing great challenges relating to their impact [
2]. Environmental knowledge and HRM policies can boost ethical consumption, according to scholars [
3]. Ecological problems are primarily caused by human activities. Natural resources are being used without restriction, resulting in the destruction of biological networks and the disturbance of natural environmental balances [
4]. According to prior studies, it was explored that about 40% of ecological deterioration occurs due to unfair consumption patterns of individuals [
5]. The exploitation of resources that destroy nature and ecosystems is directly linked to unreasonable consumption patterns [
6]. When people adopt ethical consumption practices, this has a positive effect on the growth and development of society [
7]. An eco-friendly consumer is one who protects the environment and pays attention to the relationship between purchase attitude, use of different commodities, and disposal of those commodities, in order to reduce negative ecological impacts as much as possible [
8]. Ethical consumption not only considers people’s needs but also focused on needs of the future generations [
9]. Furthermore, consumers’ CSR participation supports them in recognizing corporate values, which can help in enhancing self-esteem, achieving high moral values, and attaining individual personal needs that assist in the growth of the ecological environment [
10]. In fact, CSR participation is the involvement of consumers in philanthropic and positive social values that have the utmost positive impact on ethical behavior [
11].
Thus, the paper focuses on how consumers’ environmental knowledge influences ethical consumption behaviors and how CSR participation interacts with psychological social support, moderating ethical consumption practices.
It is essential to explore the mediating influence of CSR participation between environmental knowledge and ethical consumption links. Psychological social support enables people to cope with stressful social events while also becoming aware of the environment to consume ethically [
12]. It serves as a vital concept in the growth of ethical consumption. Although, psychological social support improves the capability to deal with traditional unethical activities and enhances ethical consumption patterns [
13]. Psychological social support provides collaboration and support for pertinent emotional and physical activities to meet ethical consumption and environmental standards. However, from the best of our knowledge, limited research has been conducted to examine the different determinants of ethical consumption (for instance, social economics [
14], social value [
15], consumers’ motivation mainstream [
16], etc.). Though no study has been carried out that jointly investigates the influence of environmental knowledge, CSR participation and psychological social support ethical consumption. Therefore, psychological social support can be explored as a moderator between environmental knowledge and ethical consumption. To investigate the selected factors, internal driving forces, and moderating variables of ethical consumption practices in tourism firms, the study designed an empirical model based on environmental knowledge, CSR involvement, and psychological social support.
Using the Saudi Arabian tourism firms as a case study, current research seeks to fill this knowledge gap in the literature by examining the direct impact of environmental knowledge, the mediating role of CSR participation, and psychological social support as a moderator. Investigating the impact of all selected constructs can help us in better understanding how environmental knowledge affects the ethical consumption of tourism firms in Arabia. Nevertheless, this research model is unique and adds several insights to the previous literature. First of all, this study’s objective is to examine how environmental knowledge is directly associated with ethical consumption. Secondly, the study proposes to assess how CSR participation mediates the relation between environmental knowledge and ethical consumption. The third objective of the study is to examine the extent to which psychological social support can strengthen the link between environmental knowledge and ethical consumption. This research suggests some theoretical and practical contributions in order to improve ethical consumption practices in tourism firms of Saudi Arabia. The paper’s remainder is as follows: firstly, in
Section 2, we describe the literature review of the selected variables; secondly, in the next section, we explain the methodology technique; in
Section 4, we include results and analysis; and in the last section, we elucidate details of discussion and conclusion.
5. Discussion
The study analyzes the ethical consumption in tourism firms, elucidates the influence of environmental knowledge and CSR participation on ethical consumption and evaluates the psychological social support moderating influence between environmental knowledge and ethical consumption.
This study carried out a series of experimental analyses based on survey data of 397 consumers. The H1 findings are congruent with previous studies, which show that environmental knowledge can act as significant means of responding to environmental challenges as it attempts to achieve ecological protection and conservation goals [
17]. Individuals with environmental knowledge are familiar with ecological issues and challenges and are capable of recognizing their impact on society and the environment [
18]. In particular, knowledge affects how people collect and use information for making ethical consumption decisions [
19]. Environmental knowledge is the key determinant of ethical consumption behavior. Moreover, environmental knowledge pushes individuals to recycle, be energy efficient, and preserve resources that encourage pro-environmental and ethical consumption behavior [
20]. Environmental knowledge is the base of ethical consumption. If consumers do not have environmental knowledge, they do not adopt ethical consumption [
43]. Moreover, environmental knowledge has a considerable influence on ethical consumption practices. However, environmental knowledge has a considerable influence on ethical consumption. This means that actions and ethical consumption are pro-environmental behaviors; there are few discrepancies in terms of impact, paths, and factors [
44]. In fact, people with pro-environmental knowledge do not predictably choose ethical consumption, and this knowledge is always affected by numerous factors like participation in CSR programs and activities [
45]. Therefore, H2 shows the CSR participation mediating role in the relationship between environmental knowledge and ethical consumption. Hence, environmental knowledge is a prerequisite to participate in programs concerning CSR, which has a positive influence on factors such as ethical values and attitudes that lead to high intellectual ethical consumption actions [
46]. According to previous studies, environmental knowledge is crucial for creating ethical environmental behavior since individuals need to know what type of actions and programs they have to join when dealing with ethical consumption [
24].
This does not indicate that environmental knowledge and ethical consumption are enough to encourage individuals to get involved in activities for the enhancement of the environment or society. Here is a dire necessity to consider CSR participation as an interplay variable in this association.
This study enlightens CSR participation’s mediating role in the relationship between environmental knowledge and ethical consumption. CSR participation is measured as a means to stimulate people to engage in different activities regarding the promotion of ethical consumption practices for the advancement of the environment and society through the antecedents of environmental knowledge [
26]. Individual distinctiveness (i.e., skills, attitudes, and knowledge regarding society and the environment) creates the basis for the commitment toward CSR activities that trigger managers’ and individuals’ interest in CSR programs [
27].
Previous studies reveal that environmental knowledge often is not sufficient to directly affect ethical consumption behavior [
28]. H2 results confirm that CSR mediates between environmental knowledge and ethical consumption links. Psychological social support is an imperative determinant of ethical consumption. Psychological social support performs a critical role in the alteration of the non-ecological safe behaviors into environment-friendly behaviors. So, this study’s H3 suggests the psychological social support moderating role between environmental knowledge and ethical consumption links. When somebody believes that ethical consumption is an advanced level of consumption, it can persuade/satisfy psychosocial motivation to achieve respect and meet economic conditions and standards set for ethical consumption [
47]. This research finding is also in line with the prior literature knowledge that it is obvious that environmental knowledge improves an individual’s abilities, competencies, skills, and discretionary efforts that lead to a high degree of involvement in the ethical consumption actions to preserve society’s resources [
29]. Individuals who have psychological social support feel good in perceiving ecological information and perform willingly in challenging ethical consumption practices, which encourage them to take part in activities concerning the protection of society or the environment [
30]. However, environmental knowledge is an initiative that enhances societal interests, competitiveness, and competencies of the firm that are mainly dependent on the frontline capabilities; hence, employees having psychological social support displays more ethical consumption behaviors than average people to accomplish the firm’s and community’s goals [
31].
Although, environmental knowledge is a guideline that exerts considerable influence on different stakeholders such as communities, customers, firms, and employees to engage in activities, programs, and actions that act as a primary source in encouraging ethical consumption [
32].
However, tourism firms have a tendency to endorse a culture that provides psychological social support to people for acquiring knowledge and awareness about ecological issues and challenges, which makes them competent to involve in practices that lead to the achievement of high ethical consumption actions [
34]. This study proves that psychological social support plays a significant role in encouraging ethical consumption in Chinese consumers.
5.1. Theoretical and Practical Implications
This study adds to the prior literature and provides certain significant guidelines for management, policymakers, and scholars that there is a critical direct relation between environmental knowledge and the impacts of ethical consumption practices. Therefore, we need to focus on different means that boost the incentives of ethical consumption behaviors. However, current tourism firm policies are highly pro-environmental about ethical consumption, and consumers also have an awareness about the ecological environment and constrained resources.
These outcomes enhance our understanding of how participation in CSR programs increases residents’ awareness and knowledge about ecological protection and build up environmental responsibility and concerns for developing ethical consumption practices. Pro-environmental knowledge is important for the whole society to make a good ecological atmosphere for natural resources protection. Therefore, we recommended that firms should launch CSR programs to increase the pro-environmental awareness of consumers and encourage their ethical consumption actions.
The pro-environmental knowledge should be popularized from different media channels such as TV, community promotions, etc., to argue about different ecological challenges and issues and motivate consumers to perform ethically. Psychosocial support is a cultural phenomenon; it can help people in achieving pro-environmental information to give positive feedback on ethical consumption practices. Thus, we suggest that firms should focus on consumer’s psychosocial competency to achieve pro-environmental knowledge for enhancing ethical consumption behaviors. The government can introduce CSR programs and seminars to praise positive commentary on ethical consumption actions. Tourism firms could also focus on promoting a significant role of environmental knowledge in improving ethical consumption behavior and quality of life in society.
5.2. Conclusions
This study confirms that environmental knowledge is a significant base for ethical consumption, and consumers’ CSR participation promotes ethical consumption behavior. Specifically, this research proves that there is a direct relationship between environmental knowledge and ethical consumption actions. Our study also demonstrates that CSR participation plays a mediating role on the relation between environmental knowledge and ethical consumption, and also acts as an amplifier for them.
Furthermore, this study also corroborates the moderating influence of psychological social support on environmental knowledge, while enhancing ethical consumption. These are the key contributions of the current research. Because most of the previous literature is likely to ignore relations of different components that affect ethical consumption actions, the conclusion of current research builds up for this shortcoming.
5.3. Limitations and Future Directions
This research has several limitations that can be seen as guidelines for future research. Our data collection was based on quantitative methods and random sampling; hence, cross-sectional and longitudinal studies may enrich the analysis in the future. Furthermore, this research has been conducted on tourism firms in Saudi Arabia and is not recommended for other industries; in the future, this empirical model should be investigated in other countries and sectors. The model can be tested with other mediating and moderating variables in future studies to provide a more comprehensive understanding of this empirical phenomenon. Moreover, there are other important determinants that influence ethical consumption as well that could be tested.
