This study employs bibliometric analysis to assess the evolution and current state of green certificate research. Drawing from the Scopus database, the study sourced 940 documents spanning from 2000 to 2022. The analysis evaluates publication trends, identifies influential works, highlights prolific authors, maps leading academic institutions, and pinpoints regional research hotspots and top publishing journals. Science mapping techniques, such as co-authorship networks, keyword co-occurrence analysis, and bibliographic coupling, are used to delineate collaborative patterns and the conceptual and intellectual structure of the field. The study reveals four salient research themes: support mechanisms and policies for renewable energy sources, sustainable renewable technologies and market dynamics, technological innovations and green certificate trading, and renewable energy investment strategies. The paper concludes by outlining practical implications and prospective research avenues, emphasizing the role of guarantees of origin, the potential of emerging technologies like AI and blockchain, and the dynamic discourse on green hydrogen certification standards. The study offers a comprehensive understanding of the field's evolution, current state, and future directions, providing valuable insights for academics, policymakers, and industry practitioners.This study employs bibliometric analysis to assess the evolution and current state of green certificate research.
