The Role of Green HRM Strategies in Engineering Project Management: A Study on the Mediating Effect of Employee Green Behavior on the Transformation Performance of Carbon Reduction Enterprise

Using survey data from 450 employees in 15 engineering companies, this study reveals the transmission mechanism of green human resource management to low-carbon transformation. The analysis found that including environmental protection track record assessment in recruitment criteria, implementing special training on energy-saving skills, and implementing performance bonus systems for carbon emission reduction can increase employees' likelihood of actively participating in green actions such as saving electricity and water by 42%. Particularly in the field of civil engineering, the correlation between green HRM measures and the emission reduction effectiveness of resource-intensive companies is 0.73. The case study shows that after a road and bridge construction company implemented an environmental assessment system, the rate of material loss on the construction site decreased by 19% year-on-year. The results provide an operational implementation plan for engineering companies to promote carbon emission reduction for all employees through human resource management.
