This research utilizes 2,527 documents sourced from the Web of Science (2019-2023), employing bibliometric analysis to construct the knowledge maps. It delves into the contemporary status of collaboration, thematic patterns, and emerging trends within this sphere of research, examining aspects such as publication year, authorial, institutional, and national collaborations, keyword clusters, evolution of keywords over time, and keyword prominence. The findings illuminate Lawrence, is the most dominant author and Chinese institutions manifest a notable upper hand in this domain. The United States and China's contributions are particularly significant.

Keyword cluster analysis reveals that air temperature, sustainable development, motivation, oceans, carbon, impact, and metamorphic rocks are currently the dominant keyword clusters. Furthermore, there is an increasing interest in the intersection of language and sustainable development within social science disciplines in recent years. Moreover, emergent research hotspots are encapsulated in highlighted terms such as education, technology, social media, and teachers. This research fosters a paradigm in language for sustainable development, aptly aligning it with the evolving zeitgeist.
