The Evolution of Carbon Market: A Systematic Review and Bibliometric Study

Background

Carbon markets are now central to climate policy because governments increasingly rely on carbon pricing to align economic decisions with emission reduction targets. As emissions trading systems and carbon taxes expand in scope and scale, policymakers and researchers need a clear picture of how underlying scholarship has developed and where knowledge gaps remain. Literature on carbon markets has grown rapidly, spanning multiple disciplines, making it difficult to track dominant themes, influential contributions, and blind spots, especially around equity, governance, and Global South experiences.

Goals and Methods

This article systematically maps two decades of research on carbon markets and their role in climate mitigation, including the intellectual structure, thematic evolution, and geographic distribution of carbon market research. The authors assemble 491 Scopus-indexed publications from 2000 to 2024 and apply systematic review and bibliometric methods using VOSviewer and Biblioshiny. The authors conduct performance analysis (e.g., output, citations, leading countries, journals) and science mapping (i.e., co-citation networks, keyword co-occurrence, thematic maps) to identify major research clusters and trending topics. The analysis distinguishes between foundational work on Kyoto mechanisms and more recent strands on carbon neutrality, pricing efficiency, and low-carbon technologies.

Conclusions and Takeaways

This review finds exponential growth in carbon market scholarship, particularly after the Paris Agreement, with China, the United States, and Australia dominating publication output. Co-citation analysis reveals five main clusters: carbon pricing policy design, market efficiency and financialization, international climate agreements, corporate carbon strategies, and technological innovation, while equity and governance perspectives remain underrepresented. The authors conclude that effective carbon markets require dynamic caps, price stabilization tools, explicit equity safeguards, and harmonized accounting standards, and recommend more research on Global South experiences and environmental integrity to support practitioners designing or reforming market mechanisms.
