Mapping the Green Taxonomy Research Landscape: A Bibliometric Analysis of Sustainability, Finance, and Policy Convergence

Green taxonomy is regarded as a system to classify economic sectors and activities that constitute sustainable activities. Although the European Union has worked to reinforce its framework for steering ecological investment, prior research has not adequately explained how green taxonomy actually shapes firms' investment choices, the movement of capital, or sustainability outcomes across different institutional contexts. This study systematically synthesizes existing research on green taxonomy through bibliometric analysis and thematic mapping to (1) identify the key research themes and their evolution, (2) review empirical evidence on green taxonomy's feasibility in promoting sustainable investments and corporate practices, and (3) reveal potential research gaps, particularly, regarding implementation challenges and regional variations. Our review identified three thematic clusters on green taxonomy research and discussed geographical, methodological, and theoretical gaps. We contribute by shedding light on the emergent research topic and their gap in research and propose future research to diversify methods to strengthen empirical foundations, broaden geographical scope beyond the EU for comparative insights, and develop case‐based studies to enhance practical relevance.
