  7. Abstract:
  8. Controlling, managing, and mitigating the emission of greenhouse gases, especially carbon dioxide, which are produced by human activities, are one of the main concerns of researchers today. Market-based methods are one the successful methods to enhance controlling, managing, and mitigating carbon dioxide emissions, among which the carbon tax has received more attention. Increasing clean technologies in the electricity network to the reduce the emissions of the electricity industry may reduce the carbon tax rate. In this regard, the life cycle analysis makes it possible to consider the emissions of the life cycle. The present model is applied for two representative days of Iran's electricity network. The carbon tax rate for January 11, 2018, for the peak demand hour (base model) for a two percent emission reduction equals to 131,247.025 Rials per ton and for three percent emission reduction equals to 313,694/825 rials per ton. The total emissions of power plants, refineries, gas transmission pipelines, and fuel transportation are 21,272.06 tons, and the total costs are 8.24 billion Rials. In summer, the natural gas as main fuel for power plants does not have too much limit, so the gas consumption of power plants was 90 percent compared to other fuels that 18 percent more than the base model on July 15, 2018. The total emissions of power plants, refineries, gas transmission pipelines, and fuel transportation are 33214.897 tons. The total costs are 14.9 billion Rials. Two scenarios of the current trend of the electricity industry and the development of the electricity industry are defined. Suppose Iran's electricity network continues its current trend, the tax rate and the share of gas and steam power plants will increase in the coming years. Suppose the electricity industry is developed by renewables and combined cycle gas power plants in the coming years, the carbon tax rate, the share of gas power plants, and emissions and total costs are reduced.
