In the context of global climate change, carbon footprint research has become a hot spot for many regions and scholars. However, a global, systematic and intuitive literature review of carbon footprint is still lacking, which has become the motivation of this research. Based on 7450 articles in the Web of Science Core Collection, this study conducted a literature review and analysis of carbon footprint from the perspective of scientometric. It is found that between 1992 and 2019, the theme of carbon footprint research has changed from ecology and botany to international trade and household behaviours, etc. Water vapour is the longest lasting carbon footprint research topic. The research scope shows a trend from small to large, that is, from the level of individuals and families to enterprises and organizations, and then to the countries and regions. Year 2008 is the main node in carbon footprint research: the classic literature before 2008 is the hubs of later research; the research after 2008 shows a significant trend of diversification and interdisciplinary development. The China's research institutions and scholars have shown an explosive trend after 2008. However, most international cooperation still occurs between North American and European countries, while developing countries such as China are still in the marginal area. The main source of knowledge for carbon footprint research is the subject “Veterinary, Animal, Science”; relatively, the research results are mainly applied to the subject “Environmental, Toxicology, Nutrition”. In addition, it is worth noting that carbon footprint research is showing a trend of merging with Economics research. These trends prove that there has been a significant theme drift and knowledge evolution process in carbon footprint research.
