Visualizing the intellectual structure and evolution of carbon neutrality research: a bibliometric analysis

Carbon neutrality is a research hotspot and achieves increasing interests in recent years. In this paper, utilizing the Web of Science database as the data resource, we conduct a series of analyses for the carbon neutrality-related literature from the past decade based on CiteSpace, including the visualization analysis for the research hotspots and trends, discovery of intellectual structure and influential directions, as well as the cooperation analysis for representative researchers, organizations, and countries. The findings demonstrate that (a) the relationship between carbon emissions and economic growth has achieved increasing academic interests in recent years. (b) There are mainly four knowledge groups at present in this area including renewable energy and carbon emissions; international energy cooperation and investment; energy regulations and policies of different countries; technological innovation and economic growth. (c) Cooperations exist widely within various authors, institutions, as well as countries, with academic clusters developed towards the goals of energy transitions, environmental sustainability, city development, etc.
