Analysis of research progress in carbon neutrality based on bibliometrics

Chinese Research Academy of Environmental Sciences

摘要

摘要:
碳中和是应对全球气候变化的重要举措，对于全球气候治理与人类命运共同体建设具有极其重要的理论与实践意义，国内外学者对碳中和的研究也在持续进行。基于Web of Science核心合集中的SCI-E与SSCI网络数据库进行检索，利用文献计量的方法，对1991—2021年碳中和研究相关论文进行数据分析与挖掘。结果表明：1991—2021年碳中和研究领域的发文量呈现显著上升趋势，研究主要集中在自然科学领域，发文量排名前3的期刊分别是Sustainability、Journal of Cleaner Production和Applied Energy；中国国家自然科学基金委员会共资助该领域459篇研究论文，远高于其他国家的相关机构；研究的中坚力量集中在美国和英国，其论文篇均被引频次分别为51.24、43.21次，远高于中国(16.91次)；目前碳中和的相关研究可以概括为碳中和技术与碳中和政策两大方面，而生物质、氢能源、碳捕集和封存等将会成为未来实现碳中和的关键性技术和主要研究方向。

Abstract:
Carbon neutrality is an important initiative to address global climate change, and it has extremely important theoretical and practical significance for global climate governance and the building of a community of human destiny. The research on carbon neutrality has been continuously conducted by scholars internationally. Based on the search of SCI-E and SSCI databases in the Web of Science core collection, the carbon neutral literature from 1991 to 2021 was analyzed and mined by using bibliometric methods. The study showed that the number of carbon neutral publications was on the rise, and the research areas were mainly concentrated in the natural sciences, with the top 3 journals in terms of the number of publications being Sustainability, Journal of Cleaner Production and Applied Energy. National Natural Science Foundation of China funded 459 studies in this field, much higher than the relevant institutions in other countries; the backbone of the research was concentrated in the United States and the United Kingdom, whose average citations per article were 51.24 and 43.21, respectively, much higher than those of China (16.91). The current carbon neutral research could be summarized in two major aspects, namely carbon neutral technology and carbon neutral policy, while biomass, hydrogen energy, carbon capture and storage, etc. were the key technologies and research directions for achieving carbon neutrality in the future.
