Abstract
This study analyzes the evolution and research trends in scientific output on ecological communication and global sustainability published between 2000 and 2024. A descriptive and retrospective bibliometric study was conducted following the PRISMA guidelines to ensure transparency and reproducibility. Data were obtained from the Scopus database using a search strategy that included titles, abstracts and keywords and inclusion and exclusion criteria were applied. A total of 382 documents were selected and analysed using the Biblioshiny interface of the Bibliometrix software. The results revealed a notable increase in scientific output since 2020, reflecting interest in green communication. India, China and the United States consolidated their positions as leading countries and stood out for their scientific output, which focused on energy efficiency, the Internet of Things and sustainable communication networks. Keyword and co-occurrence analyses revealed the consolidation in interdisciplinary research topics based on energy optimization and respect for the environment. The study concludes that it provides a bibliometric mapping and identified that research trends connect efficient communication systems with sustainable development goals related to good health and well-being, affordable and clean energy. Thus, the findings provide a valuable foundation for future research and evidence-based decision-making. The findings support future interdisciplinary research on sustainable digital infrastructures.
Keywords: Communication Networks, Global Sustainability, Internet of Things, Management, Public Policies, Technological Innovation.
