The chapter describes an interdisciplinary project that was designed and implemented within the scope of a Tourist Activities Management degree whose main topic was sustainability. Based on the use of a bilingual student blog, this project challenged students to produce multimedia content (posts, podcasts, and videos) focusing on sustainable practices and behaviors in different tourism sectors. Making use of a project-based learning approach, the strategy used is perceived as innovative having enhanced student participation and engagement. Concurrently, a preliminary analysis also suggests that there has been a positive change in the participants' awareness towards sustainability, with the different assignments and research having prompted changes in their behavior, denoting the project's pertinence, particularly in these challenging and technology-laden times.
