Energy consumption in the world is increasing for economic growth, and as a result of the emission of greenhouse gases, especially carbon dioxide, which has destructive environmental effects, the consumption of fossil fuels has an increasing trend. Present study tries to find the effect of renewable and non-renewable energy consumption on air pollution with respect to the moderating role of economic growth, utilizing the data of time series from 1990 to 2017 in Iran and with the generalized method of moments and in terms of some control variables such as energy efficiency coefficient and urbanization, the hypotheses were tested. Findings indicate that, the effect of renewable energy consumption in reducing carbon dioxide emissions (negative coefficient at a significant level of 10%) and the effect of non-renewable energy consumption in increasing carbon dioxide emissions (positive coefficient at a significant level of 5%). Also, the role of economic growth as a moderating variable on the relationship between renewable energy consumption and carbon dioxide emissions is positive and on the relationship between non-renewable energy consumption and carbon dioxide emissions is negative and significant. Developing investment and increasing the share of the renewable energy sector in the country along with improving energy efficiency and technology level can be effective in reducing air pollution.

Fossil-fuel electricity generation has a variety of harmful impacts on the environment and human health. Air pollution is the most significant impact of fossil power generation on health. This study with employing SIMPACTS-2, applies the impact pathway approach to estimate the health impacts and costs caused by air pollution of the Montazer-Qaem thermal power plant in 2011-2016 period. The results show that by removing fuel-oil and increasing the share of natural gas, the total health cost decreases from 164.9 million in 2011 to 36.4 million in 2016 (USD year 2000). During this period, the health cost per generated electricity varies from 18.1 to 4.2 USD/MWh. The low qualities of fossil fuel and high population density around the power plant have been the main factors of the high health damage costs. The health external costs can be reduced through fuel improvements. Internalizing the external costs into the price of electricity can show the true costs of fossil electricity. By taking appropriate measures, the benefits to the society can be increasedت

The purpose of this research work is the evaluation of the significant factors explaining concentration of air pollution in the city of Yazd and then explaining how the expected damage to the pollution can be evaluated. After estimating the costs due to air pollution created environmental net domestic (EDP) production is damaged. EDP obtained is 4887930630 and this amout is based upon our research that shows each resident is willing to pay 4937 Rials where is what is being cost of the present is 1627.

Statistics indicate a continuous growth in gasoline consumption for transportation in Iran. The volume of domestic consumption of gasoline in recent years has exceeded the country’s refining capacity, and a substantial volume has to be imported to meet the increasing demand for fuel. A growing urban population, together with ever increasing popularity of cars and subsidized fuel prices are considered among the most significant factors for this phenomenon. Which, among other problems, has created a substantial burden for the public budget and a rather serious air pollution in urban communities. Although, rising fuel consumption and its environmental impact could be seen as a common problem in most countries today, it is noteworthy however, that technological progress in urban transportation has presented certain useful alternatives. This study attempts to use advanced econometric methods to postulate a perspective for the long term gasoline consumption in Iran. Subsequently, it proceeds to examines the economic feasibility of utilizing a more advanced automobiles (i.e. Electro Hybrid cars) as an alternative mean for urban transportation. Findings of the study indicate a rather substantial stream of benefits for the economy, in terms of reduced gasoline consumption, as well as, lower air pollution for urban centers.

This research investigates the existence and direction of Granger causality between economic growth, energy consumption, and carbon emissions in Iran. A multivariate model including economic growth, energy consumption, carbon emissions, capital stock, labor force, and urban population is used to determine eventual causality between variables according to Toda-Yamamoto Approach. Results indicate that there is a bi-directional causality relationship between gross domestic product and CO2 emissions. Also, there is a uni-direction causality relationship from energy consumption to CO2 emissions. Finally, the results maintain that the EKC hypothesis for GDP and CO2 emissions is relevant in the period of study.
