Promoting green behavior through ethical leadership: a model of green human resource management and environmental knowledge

Abstract

Purpose

This paper aims to investigate the influence of supervisor's ethical leadership style on subordinates' green or pro-environmental work behavior in the presence of green human resource management (GHRM) as a mediator and environmental knowledge as a moderator.

Design/methodology/approach

A questionnaire-based was distributed to 427 supervisor–subordinate dyads working in various Pakistani organizations. Structural equation modeling was used to determine the mechanisms and boundary conditions in the relationship between supervisor's ethical leadership style and subordinates' green behavior.

Findings

Structural equation modeling supported a partial mediating role of GHRM in the influence of ethical leadership on green work behavior. Further, the findings revealed that employee's environmental knowledge can magnify the indirect impact of ethical leadership, via GHRM, on green behavior.

Research limitations/implications

Cross-sectional survey data are typically associated with common method bias. To counter this bias, we collected data from dual sources, namely, supervisors and their subordinates. The research findings have implications in deepening the understanding of the impact of ethical leadership in improving environmental performance of the organization.

Originality/value

This is the first study that utilizes multi-sourced data to examine the mediating role of GHRM and the moderating role of environmental knowledge in the relationship between ethical leadership and green behavior at work.
