Employees play a pivotal role in achieving corporate environmental sustainability, but the rapid and widespread adoption of generative Artificial Intelligence in workplaces adds complexity to this goal. This study examines the relationship between perceived organizational support toward the environment and employee green behavior in the workplace, with a focus on how organizational support for generative Artificial Intelligence influences this relationship. Using data from a survey of 269 employees at a multinational mechanical engineering company, the study confirms a positive relationship between perceived organizational support toward the environment and employee green behavior. This finding suggests that employees who perceive a strong organizational commitment to environmental initiatives are more likely to engage in eco-friendly behaviors. However, contrary to expectations, perceived organizational support for generative Artificial Intelligence negatively influences this relationship, indicating a potential conflict between promoting generative Artificial Intelligence technologies and encouraging green behaviors in the workplace. These findings highlight the importance of strategically integrating technological and environmental goals. Organizations must carefully align these initiatives to avoid undermining their environmental goals. Strategies such as adopting eco-friendly technologies or showcasing positive examples of Artificial Intelligence used for green projects may help harmonize these efforts.
