Impact of Green Transformational Leadership and Green Human Resource Management on Sustainable Project Management in the Projects of Pakistan: Moderated Mediation Model

Abstract

Sustainable project management in Pakistan's construction sector is essential for mitigating environmental impacts, maximizing resource efficiency, and improving project success in the context of rising urbanization and resource limitations. This study examines the antecedents of Sustainable Project Management (SPM) specially see the influence of Green Transformational Leadership (GTL) along through the intervening effect of Green Human Resource Management (GHRM), with Perceived Organizational Support (POS) serving as a moderating variable. Data were obtained from professionals engaged in sustainability projects in the construction sector of Pakistan using Partial Least Squares Structural Equation Modeling (PLS-SEM) to investigate the potential links. The outcomes indicate that both GTL substantially affect SPM, with GHRM serving as a partial mediator of these influences, underscoring the significance of organizational support in improving sustainable project results. The research enhances the literature by amalgamating leadership, human resource management, and support mechanisms within sustainable project practices. Managerial implications indicate the necessity of promoting green leadership and human resource practices within supporting organizational contexts to attain sustainability objectives in project management. Limitations encompass possible contextual constraints and the cross-sectional approach, indicating opportunities for longitudinal and cross-cultural research.
