The increase in environmental awareness within business life has provided an opportunity for the development of green human resource management practices. The positive corporate image created by GHRM encourages many employees and enhances their work engagement. GHRM practices make employees feel proud of their organisation and create a values-based foundation for working in their current companies. In fact, the internalised green proclivities of organisations, namely the alignment of values between the organisation and employees, can make their employees feel a greater psychological ownership of their companies, leading to increased engagement as suggested by social identity theory.
