Project – The Impact of Green Human Resource Management Practices on Employee Behaviour and Environmental Sustainability: A Study of Selected Manufacturing Firms in Ogun State.

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Environmental sustainability has become an important consideration in contemporary business management because manufacturing activities depend on natural resources and may generate waste, emissions, wastewater, noise, and other forms of environmental pressure. As organisations seek to maintain productivity and profitability, they are increasingly expected to consider the environmental consequences of their production processes and adopt responsible business practices. The United Nations (2015), through the 2030 Agenda for Sustainable Development, established goals relating to responsible production and consumption, climate action, and the protection of natural resources. Similarly, the International Organization for Standardization (2015), through ISO 14001, provides a framework for establishing and improving environmental management systems. These developments demonstrate that environmental sustainability is not solely a technical responsibility involving machinery and production processes; it also requires appropriate organisational policies, employee participation, and management commitment. Consequently, manufacturing firms need management approaches that encourage employees to integrate environmental responsibility into their everyday work activities.

Green Human Resource Management (Green HRM) has emerged as an approach that integrates environmental objectives into human resource management policies and practices. It involves incorporating environmental considerations into recruitment, selection, training, performance appraisal, employee participation, rewards, and other workforce management activities. The central idea is that employees are essential to implementing organisational environmental strategies because their decisions and behaviours influence resource consumption, waste generation, compliance with environmental procedures, and the effective use of production equipment. Jackson et al. (2011) emphasised the importance of expanding human resource management’s contribution to environmentally sustainable organisations. Renwick et al. (2013) examined Green HRM through the ability–motivation–opportunity framework, explaining how human resource practices can develop employees’ environmental abilities, motivate them to participate in environmental initiatives, and provide opportunities for environmental involvement. This perspective positions Green HRM as a strategic management approach through which manufacturing organisations can connect workforce development with environmental objectives.

Green recruitment and selection involve attracting and appointing employees whose competencies, attitudes, and values support an organisation’s environmental objectives. Organisations may communicate their environmental commitments to prospective employees and consider relevant environmental knowledge or willingness to participate in sustainability initiatives when making recruitment decisions. Green training complements these activities by equipping employees with the knowledge and skills required to reduce waste, conserve energy, handle materials safely, and comply with environmental procedures. Renwick et al. (2013) identified recruitment, training, performance management, and employee involvement as relevant areas through which human resource management can support environmental management. Similarly, Jabbour and Santos (2008) discussed the relationship between environmental management and human resource management, emphasising the importance of integrating environmental concerns into organisational people-management processes. In manufacturing firms, these practices may help workers understand the environmental implications of their duties and develop practical competencies for carrying out production activities in more environmentally responsible ways.

Green performance management involves incorporating environmental responsibilities into job descriptions, performance appraisal, supervisory feedback, and organisational performance standards. Green rewards and recognition may also be used to encourage employees to comply with environmental policies, propose resource-saving improvements, and participate in workplace sustainability initiatives. Employee behaviour is particularly important because environmental policies may produce limited results when workers do not follow established procedures or participate actively in environmental programmes. Dumont et al. (2017) empirically examined the relationship between Green HRM practices and workplace green behaviour, finding that Green HRM influenced in-role green behaviour directly and indirectly, while its influence on extra-role green behaviour operated through employees’ psychological green climate. Their findings suggest that formal human resource practices can shape employees’ environmental conduct, although the mechanisms may differ depending on the type of behaviour. In manufacturing organisations, appropriate performance standards, recognition systems, and supervisory support may therefore encourage employees to reduce unnecessary resource consumption, report environmental hazards, follow waste-management procedures, and voluntarily contribute to workplace environmental improvement.

Employee behaviour represents a central link between Green HRM practices and environmental sustainability. Workplace green behaviour may include switching off unused equipment, reducing unnecessary paper and material consumption, separating waste, preventing avoidable spills, following pollution-control procedures, and suggesting improvements to production processes. Such behaviour can be classified into in-role behaviour, which forms part of an employee’s formal responsibilities, and extra-role behaviour, which involves voluntary environmental actions beyond prescribed duties. Dumont et al. (2017) demonstrated that Green HRM practices can influence both forms of workplace green behaviour through different psychological processes. Norton et al. (2015) also reviewed workplace pro-environmental behaviour and highlighted the importance of individual, organisational, and contextual factors in explaining environmentally responsible conduct at work. These findings indicate that employees’ environmental behaviour depends not only on personal awareness but also on workplace expectations, management support, organisational culture, and opportunities to participate. Green HRM may therefore provide a structured means of translating environmental policies into everyday employee actions within manufacturing firms.

Environmental sustainability in manufacturing involves managing resources responsibly, preventing pollution, reducing waste, improving energy efficiency, and limiting the adverse environmental consequences of production activities. Although technological investment and environmental management systems are important, their effectiveness may depend on employees’ willingness and ability to implement environmental procedures consistently. Renwick et al. (2013) argued that human resource practices can contribute to environmental management by developing employee competencies, strengthening motivation, and creating opportunities for participation. In addition, ISO 14001 provides an environmental management framework that emphasises systematic processes for managing environmental responsibilities and improving environmental performance (International Organization for Standardization, 2015). Integrating Green HRM with environmental management may help organisations establish clearer responsibilities, provide relevant training, encourage employee suggestions, and reinforce compliance with environmental standards. Nevertheless, the adoption of Green HRM does not automatically guarantee improved environmental outcomes because results may also depend on leadership, production technology, financial resources, regulatory compliance, and the consistent implementation of environmental policies.

Ogun State provides a relevant setting for examining Green HRM because of its manufacturing and industrial activities, including production, processing, packaging, and related operations that require coordinated workforce management and environmental control. Manufacturing employees may encounter environmental responsibilities involving energy use, raw materials, chemical handling, wastewater, emissions, packaging, and solid waste, depending on the industry and production process. The National Environmental Standards and Regulations Enforcement Agency (Establishment) Act 2007 provides a statutory framework for environmental standards and enforcement in Nigeria, while the National Environmental (Permitting and Licensing System) Regulations 2009 establish requirements relating to relevant environmental permits and licences. These frameworks underscore the importance of environmental compliance within applicable industrial activities. However, compliance requirements and environmental technologies alone may be insufficient if employees lack relevant knowledge, motivation, training, or managerial support. Against this background, the present study examines the impact of Green Human Resource Management practices on employee behaviour and environmental sustainability in selected manufacturing firms in Ogun State. It seeks to establish whether practices such as green recruitment, green training, environmental performance management, green rewards, and employee participation are associated with environmentally responsible workplace behaviour and organisational environmental outcomes.

1.2 Statement of the Problem

Despite increasing attention to environmental sustainability, manufacturing firms may continue to experience difficulties translating formal environmental policies into consistent employee practices. Production activities often require the use of energy, water, raw materials, chemicals, and packaging materials, while some processes generate waste, emissions, and wastewater. Although environmental management systems and regulatory requirements provide a framework for controlling these impacts, the effectiveness of environmental initiatives may depend on employees’ knowledge, motivation, and willingness to comply with established procedures. Jackson et al. (2011) emphasised the need for human resource management to contribute more directly to environmental sustainability, while Renwick et al. (2013) identified the importance of integrating environmental objectives into workforce management. The problem, therefore, is whether selected manufacturing firms in Ogun State adequately use Green HRM practices to encourage environmentally responsible employee behaviour and support environmental sustainability.

A second concern relates to the behaviour of employees in implementing workplace environmental policies. Employees may be aware of environmental rules but fail to follow them consistently when training is inadequate, supervisors provide limited encouragement, environmental performance is not monitored, or environmentally responsible conduct receives little recognition. Such circumstances may weaken the connection between organisational environmental objectives and employees’ everyday decisions. Dumont et al. (2017) found that Green HRM practices influenced employees’ in-role and extra-role green behaviour through different direct and indirect mechanisms, including the psychological green climate of the workplace. This finding suggests that environmental policies need to be supported by appropriate human resource practices and a workplace climate that encourages environmental responsibility. However, the extent to which green recruitment, training, performance appraisal, rewards, and employee participation influence employee behaviour in selected manufacturing firms in Ogun State requires empirical investigation.

Another problem concerns the extent to which employee behaviour contributes to environmental sustainability outcomes. Manufacturing firms may introduce environmental programmes and invest in pollution-control equipment without fully achieving their intended outcomes if employees do not use resources efficiently, follow waste-management procedures, report environmental incidents, or comply with established operating standards. ISO 14001 emphasises the systematic management of environmental responsibilities and continual improvement in environmental performance (International Organization for Standardization, 2015). However, the existence of an environmental management framework does not, by itself, establish that employees’ daily actions or human resource practices produce measurable improvements in resource conservation, waste reduction, pollution prevention, and environmental compliance. It is therefore necessary to investigate the relationship between Green HRM practices and environmental sustainability in the selected firms while recognising that environmental outcomes may also depend on technology, capital investment, leadership, and regulatory enforcement.

Furthermore, although international research has established a basis for examining Green HRM and employee green behaviour, its findings cannot automatically be generalised to every manufacturing organisation or industrial setting. Differences in organisational size, production processes, management commitment, workforce skills, financial capacity, and environmental requirements may influence the adoption and effectiveness of Green HRM practices. Renwick et al. (2013) identified gaps in the development and application of Green HRM, while Dumont et al. (2017) demonstrated that the relationship between Green HRM and employee behaviour can operate through different mechanisms. These findings justify examining the issue within a specific organisational context. The central problem addressed by this study is the need for context-specific evidence on how Green HRM practices influence employee behaviour and environmental sustainability in selected manufacturing firms in Ogun State, Nigeria.

1.3 Objectives of the Study

2. How does green training and development affect employee environmental behaviour in selected manufacturing firms in Ogun State?
3. What effect do green performance management and reward practices have on environmental sustainability in selected manufacturing firms in Ogun State?
4. What relationship exists between employee environmental behaviour and environmental sustainability in selected manufacturing firms in Ogun State?

1.5 Research Hypothesis

H₀: Green Human Resource Management practices have no statistically significant relationship with employee environmental behaviour and environmental sustainability in selected manufacturing firms in Ogun State.

1.6 Significance of the Study

The study is expected to be beneficial to manufacturing firms, employees, human resource managers, environmental management personnel, policymakers, researchers, and students.

Manufacturing firms: The findings may help manufacturing organisations understand how human resource practices can support environmental objectives. The results may inform decisions concerning green recruitment, environmental training, employee participation, performance appraisal, and rewards for environmentally responsible conduct.

Employees: The study may improve employees’ awareness of their responsibilities in promoting environmental sustainability. It may encourage participation in waste reduction, energy conservation, responsible material use, pollution prevention, and compliance with workplace environmental procedures.

Human resource managers: The findings may provide useful information for integrating environmental objectives into recruitment, training, performance management, employee engagement, and reward systems. This may assist human resource managers in developing policies that encourage employees to demonstrate environmentally responsible behaviour.

Environmental management personnel: The study may help environmental officers and sustainability coordinators understand the importance of employee involvement in implementing environmental policies. The findings may inform collaboration between human resource departments and environmental management units.

Government and policymakers: The findings may offer context-specific information for discussions concerning environmental compliance, industrial sustainability, employee education, and the implementation of environmental management policies in manufacturing organisations.

Researchers and students: The study may contribute to academic discussions on Green HRM, employee environmental behaviour, and environmental sustainability. It may also provide a foundation for further studies in other industries and geographical locations.

1.7 Scope of the Study

The study focuses on the impact of Green Human Resource Management practices on employee behaviour and environmental sustainability in selected manufacturing firms in Ogun State, Nigeria.

Geographically, the research will be conducted in selected manufacturing firms located within Ogun State. The specific firms will be identified based on their relevance to the study, accessibility, and willingness to participate.

In terms of content, the study will examine green recruitment and selection, green training and development, green performance management, and green rewards. Employee environmental behaviour will cover workplace practices such as resource conservation, waste reduction, compliance with environmental procedures, and voluntary participation in environmental initiatives. Environmental sustainability will be examined through relevant indicators such as perceived improvements in resource efficiency, waste management, pollution prevention, and environmental compliance.

The study will cover eligible employees and, where appropriate, human resource or environmental management personnel in the selected firms. Data will be collected using an appropriate research instrument, such as a structured questionnaire, and analysed using statistical techniques suitable for the research questions and hypothesis. The conclusions will primarily apply to the participating firms and should not automatically be generalised to all manufacturing organisations in Ogun State.

1.8 Limitations of the Study

The study may face limitations relating to access to manufacturing firms, the availability of employees, and respondents’ willingness to disclose information about organisational environmental practices. Some firms may regard information concerning environmental performance or internal human resource policies as confidential.

The study may also depend on self-reported information, which may be affected by respondents’ perceptions or their desire to provide socially acceptable answers. Where actual environmental performance records are unavailable, employee assessments of environmental sustainability may not fully reflect independently measured environmental outcomes.

Furthermore, the focus on selected manufacturing firms in Ogun State may limit the extent to which findings can be generalised to other industries or locations. If the research adopts a cross-sectional survey design, it will be possible to examine statistical relationships, but the results alone will not establish causation over time. These limitations will be addressed, where practicable, through confidentiality assurances, clear questionnaire items, appropriate sampling procedures, and the use of suitable statistical methods.
