{Reference Type}: Journal Article {Title}: The Impact of Environmental Volunteering on Employees, Companies, and Local Communities: A Case Study on Romanian Companies. {Author}: Puiu S;Udriștioiu MT; {Journal}: Int J Environ Res Public Health {Volume}: 21 {Issue}: 5 {Year}: 2024 May 16 {Factor}: 4.614 {DOI}: 10.3390/ijerph21050631 {Abstract}: This paper addresses the importance of organizational environmental volunteering as part of the corporate social responsibility (CSR) strategies of organizations. If more organizations support their employees' involvement in such projects, there can be hope for mitigating climate change and making the transition to a more sustainable world. We used partial least squares structural equation modeling to analyze the impact of management support on organizational environmental volunteering and of the latter on the employees' well-being and productivity. Making environmental volunteering part of an organization's CSR strategy can help the environment, the employees, and the organization itself. The results show a direct and positive relationship between management support and organizational environmental volunteering and between the latter and both the well-being and productivity of employees. The findings will help managers in both public and private organizations to better shape their strategies and encourage their employees to get involved in projects meant to reduce pollution and the carbon footprint.
