The present study analyzed YouTube sustainable design communities (with an emphasis on Academia) in English and Spanish through webometric methods. Findings included differences between the networks in terms of speakers and popular videos. Network centralities revealed that English videos form a community with multiple interconnections between universities and other stakeholders, while Spanish videos are mostly small groups and isolated nodes. Despite being well connected, videos related to universities were less popular than videos unrelated to universities. Nevertheless, videos related to students were key in spreading sustainable design content in both networks. The findings also suggest some factors that may be playing in favor of English based content.
