This study provides a comprehensive bibliometric analysis of green certificates research, examining its evolution, current state, and future directions. The analysis is based on 940 documents published between 2000 and 2022, sourced from the Scopus database. The research identifies key trends, influential works, prolific authors, institutions, countries, and journals in the field. It also explores collaborative patterns, conceptual structures, and emerging research themes. The study highlights the growing importance of green certificates in promoting renewable energy and sustainability, with a focus on support mechanisms, market dynamics, technological innovations, and policy frameworks. The analysis reveals that China is the most prolific contributor, followed by the United States, the European Union, and Scandinavian countries. The top journals in the field include Energy Policy, Renewable and Sustainable Energy Reviews, and Renewable Energy. The study also identifies key research themes, such as renewable energy support schemes, policy comparisons, and the integration of emerging technologies like blockchain. The findings underscore the need for further research in areas such as green hydrogen certification, renewable energy investment strategies, and the role of artificial intelligence in green certificate trading. The study concludes that green certificates play a crucial role in advancing sustainability goals and that future research should focus on enhancing transparency, improving market mechanisms, and exploring new technologies to support the transition to renewable energy.This study provides a comprehensive bibliometric analysis of green certificates research, examining its evolution, current state, and future directions.
