The global economies continue to observe a consistent increase in carbon emissions, making it problematic to achieve the Paris agreement goals on the environmental variations. To notify strategies, and mitigate carbon emissions, it is important to recognize the issues that affect on it. Considring this view, this study explores the impact of autocracy, democracy, and the globalization process on the carbon dioxide (CO 2 ) emissions for 74 developing countries during the period from 1990 to 2016 by using the stochastic impacts by regression on population, affluence, and technology (STIRPAT) model framework. The results based on a robust system generalized method of moments (SYS-GMM) indicate that autocracy, political globalization, economic growth, financial development, energy consumption, and gross fixed capital formation significantly enhance environmental degradation, while democracy, economic, social, and overall globalization significantly reduce it. Additionally, the results are robust to various robustness checks, which confirm the consistency of the findings. This study also offers various useful policy implications to the governments; regulatory authority and policymakers in general, and specifically analyzed developing countries for promoting environmental sustainability.
