As an important indicator of greenhouse gas emissions, the carbon footprint (CF) has become increasingly important in recent years under the dual pressures of global warming and international commitments to mitigate its effects. This study collected 3698 papers related to CF from the Web of Science database as research samples (year 2007 to 2018). Based on CiteSpace, the knowledge base, popular topics, and research trends of CF are presented. The results show the following: (1) from 2007 to 2018, the number of articles on CF have steadily increased. (2) After spatial analysis of the literature, we found that among research institutions, the Chinese Academy of Sciences has the largest number of publications on the issue. When it comes to country, three important research forces can be identified: USA, China, and UK. (3) Research on the CF is interdisciplinary; in addition to the traditional fields of environmental, political, economics, and computing, CF research has received attention from the Physics, Materials, Chemistry, Mathematics, and animal sciences. (4) Through keyword clustering, currently popular topics in research can be roughly divided into four aspects: CF calculation methods, research scales, energy, and agriculture. (5) The CF research during the study period is divided into four stages according to the burst time and content of the burst keywords. According to the research status and trend, this paper puts forward the future research direction of carbon footprint.
作为温室气体排放的一个重要指标，碳足迹（CF）在全球变暖的双重压力和国际社会减轻其影响的承诺下，近年来变得越来越重要。本研究从 Web of Science 数据库中收集了 3698 篇与 CF 相关的论文作为研究样本（2007 年至 2018 年）。基于 CiteSpace，呈现了 CF 的知识基础、热门主题和研究趋势。结果表明：（1）从 2007 年到 2018 年，CF 的文章数量稳步增加。（2）对文献进行空间分析后，我们发现，在研究机构中，中国科学院在该问题上的出版物数量最多。就国家而言，可以确定三个重要的研究力量：美国、中国和英国。（3）对 CF 的研究是跨学科的；除了环境、政治、经济和计算机等传统领域外，CF 研究还受到物理学、材料学、化学、数学和动物科学的关注。（4）通过关键词聚类，可以大致将目前研究的热门主题分为四个方面：CF 计算方法、研究规模、能源和农业。（5）根据爆发关键词的时间和内容，将研究期间的 CF 研究分为四个阶段。根据研究现状和趋势，本文提出了碳足迹的未来研究方向。
