Abstract
The global economy has witnessed rapid events over the past few years, which causesconcerns about climate change, and uncertainties. Over the past few decades, greenhouse gas emissions have been identified as one of the main causes of global warming, which eventually leads toclimate change. Therefore, investigating the effective factors on increase in carbon dioxide emissions as one of the most important types of greenhouse gases is of particular importance. In this regard, the purpose of this study is to investigate The effect of effective factors on carbon dioxide emissions in Iran, emphasizing the effect of economic policy uncertainty using Autoregressive distributed lag model (ARDL) during the period of 1997-2020. The research results indicate thatthat in the long term, the economic policy uncertainty variable has a positive effect on carbon dioxide emissions and reduces the quality of the environment. Also, regarding the other investigated variables, it can be stated that the consumption of renewable energy has a negative and significant effect on the emission of carbon dioxide and that they are compatible with the environment and help to improve the quality of the environment. Also, urbanization has a negative effect on carbon dioxide emissions. Considering thatOne of the reasons for the higher uncertainty index in low-income economies is the more unstable economy (they are more damaged by external shocks) and more domestic political shocks. therefore, it is suggested that long-term and stable policies be adopted by the government and help to improve the quality of the environment by paying attention to the correct announcement of applied policies and the timely publication of economic information that will lead to reducing the Economic Policy Uncertainty. Also, anticipating global uncertainties, adopt policies to reduce their effects.
