Green credits: A bibliometric analysis of publications in the Web of Science

Abstract

Sustainable development goals emphasize disseminating projects that do not pollute the environment. Green credit is one of the primary tools used to support and finance environmentally friendly projects. Thus, green credits appear to be a current research area. This research aims to conduct a bibliometric analysis of studies on green credits. To achieve this goal, we reviewed 2,630 studies published in the Web of Science database between 1980 and 2024. We presented the changes in the number of studies and citations over time, along with details about the most cited studies. In the literature review section, in particular, studies published recently were examined. Then, we categorize the studies based on document and index type, written language, countries, subjects, and citation categories. Our main results are: The most intense years for studies on green credits are 2022 and 2023. 98% of the studies were published in English, with over 80% being article-based. China leads the list of countries to conducting the most studies. The first three categories with the most studies are environmental sciences, green sustainable science technology, and economics. As the number of studies increased over time, citations also increased.
