This study investigates the dynamic interrelationships between renewable energy production and key environmental and economic indicators in Uzbekistan, including CO₂ emissions, PM2.5 air pollution, green foreign direct investment (FDI), and energy efficiency. Using a Vector Autoregression (VAR) model with annual time series data from 2012 to 2024, the analysis reveals significant bidirectional causal links among the variables. The results indicate that increases in green FDI and improvements in air quality significantly drive renewable energy development. However, the limited reverse impact from renewable energy to CO₂ reduction suggests a gap in implementation and integration. Granger causality tests confirm that environmental and investment factors strongly influence both energy efficiency and renewable output. The findings highlight the importance of strategic policy measures focused on green investment, pollution control, and sustainable energy reforms. This research contributes to the understanding of sustainable energy transitions in developing economies and offers evidence-based insights for shaping Uzbekistan’s green energy future.
