Global Trend of Carbon Emissions Based on Year: A Bibliographic Study

Abstract

One of the causes of increasing global warming or climate change is the high carbon emissions on earth, which impacts on the environment, health, and economic instability. This study conducts a qualitative mapping of research articles on carbon emissions from 2011 to 2022, focusing on publication year, publisher accreditation, theory used, research methods, research units, analysis period, sample size, research variables, and results. A total of 113 articles from accredited and Scopus indexed journals are included in the analysis, with the majority published in 2021. The Journal of Cleaner Production is identified as the most prominent publisher discussing carbon emissions. Most journals included in this study are classified as Scopus Q1. The theory of legitimacy is found to be the most commonly used theory, with quantitative methods being the dominant research approach. Country-level analysis is the most prevalent unit of analysis, with a coverage period of 1 year. The dependent variable in most quantitative studies is CO2 emissions, while GDP per capita (PI) is often used as the independent variable. Carbon emissions are a critical concern globally due to their impact on climate change, environment, health, and economic stability.
