This bibliometric analysis explores the intersection of sustainability, strategic alliances, and carbon footprint reduction, with a focus on IT-Energy collaborations. This research uses a bibliometric analysis of Scopus-indexed documents (1995–2025), employing VOSviewer to map trends, citation networks, key contributors, and co-authorship patterns, revealing the growing significance of sustainability research in the context of cross-sector alliances. Key findings indicate a surge in publications since 2018, peaking at 142 in 2024, and highlight the prominence of journals such as Sustainability, Strategic Management Journal, and Journal of Cleaner Production. The study identifies four major thematic clusters: Economic & Business Strategies, Innovation & Corporate Strategy, Human & Health Dimensions, and International Policy & Cooperation. It also reveals a shift from economic-industrial themes (2010–2014) to social and innovation-driven dimensions (2018–2020), with underexplored areas in Artificial Intelligence (AI), blockchain, and Internet of Things (IoT). The results suggest opportunities for policy development and interdisciplinary research to accelerate green energy solutions. The analysis also underscores the importance of global partnerships, with the U.S., U.K., and Australia leading contributions. Finally, our temporal keyword analysis offers a novel lens for sustainability research, guiding future studies toward technology-driven alliances for carbon footprint reduction.
