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