In this research, two patterns have been explained to investigate the relationship between income inequality and environmental degradation in Iran's provinces in 1393-1399 using the generalized least squares method. The results of the panel Granger causality test show that there is one-way causality from income inequality to environmental destruction. According to the results of the first model, income inequality has a positive and significant effect on the pollution index; This means that with an increase of 1 unit of inequality, the total amount of pollution (CO2 emission) increases by 5876232 units. The variables GDP per capita and the square root of GDP per capita do not have a statistically significant effect on CO2 emissions; In this way, during the period under review, the environmental hypothesis of Kuznets is not confirmed in the provinces of Iran. In addition, education and energy intensity have a negative and significant effect and the industry structure has a positive and significant effect on environmental pollution. According to the results of the second model, the amount of CO2 emission has no significant effect on the inequality index. In addition, the GDP per capita variable has a statistically significant and negative effect on the inequality index; This means that with an increase of 1 unit of GDP (income) per capita, the inequality decreases by -0.0592 units. On the other hand, the second power of GDP per capita has a positive and significant effect on income inequality;
