The relentless rise in global carbon dioxide (CO₂) emissions presents a formidable challenge to climate stability and sustainable development. This study provides a comprehensive, integrated assessment of the key drivers of CO₂ emissions, moving beyond isolated analyses to examine the simultaneous impact of energy consumption patterns, financial mechanisms, institutional frameworks, and innovation capacity. Utilizing a balanced panel dataset spanning the years 2000 to 2024 for ten major and emerging economies (Argentina, Brazil, China, India, Indonesia, Mexico, Russia, Saudi Arabia, South Africa, and Turkiye), the research employs fixed effects regression models to test a series of hypotheses derived from the Environmental Kuznets Curve (EKC) and related theoretical literature. The empirical findings robustly confirm that renewable energy consumption and research & development (R&D) expenditure significantly reduce CO₂ emissions. Conversely, fossil fuel energy consumption and GDP growth exhibit strong positive effects, underscoring their roles as primary emission drivers. The study also identifies green finance (proxied by financial development) and institutional quality as significant negative determinants, highlighting the critical enabling roles of sustainable financial systems and effective governance in the decarbonization process. Among the control variables, population growth shows a positive association with emissions, while the effects of GDP per capita growth and foreign direct investment (FDI) are statistically ambiguous in the selected sample. The results offer significant theoretical contributions by integrating multiple drivers into a unified framework and advancing the EKC discourse. Practically, the study provides evidence-based policy implications, emphasizing the need for accelerated renewable energy deployment, fossil fuel subsidy reforms, enhanced green R&D investment, strengthened environmental governance, and the scaling up of green finance instruments to achieve sustainable, low-carbon economic growth.
