With global climate change becoming increasingly serious, carbon neutrality, a key strategy to mitigate climate change, has attracted widespread attention. However, due to the multidisciplinary and complexity of carbon neutrality studies, as well as the diversification of research content, a comprehensive review and systematic synthesis of which is quite limited. In this paper, a bibliometric analysis on the topic of carbon neutrality is conducted to reveal the research progress from a quantitative and visual perspective and describe the evolution of research hotspots. The results show that carbon neutrality research is abundant at both the macro and micro levels. Low carbon development is the premise of carbon neutrality, and emission reduction and carbon sinks are the basis of carbon neutrality. The degree of research varies significantly in different countries, with China dominating in the number of publications, followed by the USA and the UK. The realization of carbon neutrality cannot be fully achieved by one single perspective and requires a comprehensive and systematic analysis of technology, economy, and society. Carbon neutrality is a technology-driven process guided by policy. Economically, carbon taxes and carbon markets are two important market mechanisms for reducing carbon emissions. Technically, researches of negative carbon technologies and renewable energy are growing rapidly. Carbon market, carbon negative technology, circular economy, and green energy will become the focus of future research. This paper helps scholars to understand the overall state of carbon neutrality research and provides a historical reference for future research.
随着全球气候变化日益严重，碳中性作为一种缓解气候变化的关键策略，已经引起了广泛关注。然而，由于碳中性研究的跨学科性和复杂性，以及研究内容的多样化，对其进行全面的回顾和系统的综合分析是相当有限的。本文对碳中性这一主题进行了文献计量分析，从定量和可视化的角度揭示了研究进展，并描述了研究热点的演变。结果表明，碳中性研究在宏观和微观层面都很丰富。低碳发展是碳中性的前提，减排和碳汇是碳中性的基础。不同国家的研究程度差异显著，中国在出版物数量上占据主导地位，其次是美国和英国。碳中性的实现不能仅从单一视角出发，需要对技术、经济和社会进行全面和系统的分析。碳中性是一个由政策指导的技术驱动过程。在经济方面，碳税和碳市场是减少碳排放的两个重要市场机制。在技术方面，负碳技术和可再生能源的研究正在迅速发展。碳市场、碳负技术、循环经济和绿色能源将成为未来研究的重点。本文有助于学者了解碳中性研究的整体状况，并为未来的研究提供历史参考。
