With the increasing need for powerful communication for environmental issues, XR technologies—encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)—offer immersive and interactive platforms that can engage audiences in unique ways. The paper examines how VR can transform traditional PR campaigns, enabling organizations to create compelling, experiences that raise awareness, influence public behavior, and foster a deeper connection with sustainability goals. By conducting interviews with PR professionals and environmental organizations, the paper also highlights the effectiveness, challenges, and future potential of XR-driven campaigns. And how XR technologies can enhance audience engagement, improve message retention, and provide actionable insights for environmental advocacy, making them powerful tools for driving the global sustainability plan.
