The purpose of this paper is to study The social cost of carbon (SCC) is an important concept for understanding and implementing climate change policies, In Iran using economic data of the time period (1390-1395). This term represents the economic cost caused by an additional ton of carbon dioxide emissions or its equivalent. In this study three approaches to investigate and compare the results have been used, the approach is the use of applying the Dynamic Integrated model of Climate and Economy (DICE-2016R). World Bank indices and energy balance sheet, the amount of years of life lost. The study estimates that the SCC is 513891.232 Rial per ton of CO2 in 1395 and international prices for the current period (1400). Also, the results indicate that, following the implementation of carbon emission control policies, production and consumption in early periods will be reduced And with the replacement of technology, it's going up. The important point of the paper is that using the lost years of life results in more reliable results than other methods.
