This study examines the asymmetric effects of per capita income, oil prices, industrial value added, and foreign direct investment on CO2 emissions in Iran through a non-linear distributed lag autoregression model (NARDL) from 1989 to 2023. This study also discusses the pollution safe haven hypothesis and the Kuznets U-shaped curve simultaneously and asymmetrically for Iran. Based on the results of this study, only the per capita income variable has a linear relationship with CO2 emissions, while the other variables have a non-linear relationship. The model results showed that OPEC oil prices have an inverse relationship with pollution emissions only in positive shocks. For the foreign investment variable, only a negative shock positively affects pollution emissions, which indicates that Iran is not a pollution-safe haven for other countries. Also, industrial value added only has a positive effect on positive shocks. On the other hand, per capita income has a negative effect on pollution emissions. Finally, this study's findings showed that the U-shaped Kuznets curve is not true for Iran
