This article analyzes the effectiveness of environmental taxes in reducing carbon dioxide (CO₂) emissions
in Uzbekistan using econometric methods. Based on panel data covering the period 2000–2023, the Autoregressive
Distributed Lag (ARDL) model and the Granger causality test were applied. The research findings indicate that a 1 percent
increase in the share of environmental tax revenues in GDP leads to a 0.43 percent reduction in CO₂ emissions in the long
run. At the same time, industrial production and population income levels were found to have a significant impact on
emissions. As policy recommendations, the study proposes the gradual introduction of a carbon tax and the provision of
tax incentives for green investments.
