ABSTRACT
Many countries have made carbon neutrality pledges in response to climate change. In this study, we collected 2,918 publications related to carbon neutrality from the Web of Science and conducted a bibliometric analysis. In this field, we discovered: (1) The number of publications has gone through three phases, with 66.6% of total publications during 2015–2021; research was dominated by the US, with four of the ten most influential institutions coming from it. In 2016, China exceeded the UK in terms of annual publications and ranked second. (2) Academic collaboration among the Top 20 productive countries was extensive, with co-authors from 12 of the 20 countries publishing more than 50% of the total. (3) Co-word analysis indicated that during 2000–2007, researchers focused mainly on ecological carbon sinks; during 2008–2014, carbon markets, bioenergy, and bio-based products attracted attention; during 2015–2021, carbon sequestration technologies, hydrogen, and fuel cells were the focus.

Notes
1. Because carbon neutrality is a relatively new concept, the search period was 2000–2021 and the following results show that there were few carbon neutrality-related studies before 2007.
2. In this study, the publications from China included data from Taiwan, Hong Kong, and Macau; the publications from the UK consisted of data from England, Wales, Scotland, and Northern Ireland.
