An ecosystem is considered to be one of the cornerstones of human life, with its evolution and development in the world. The phenomenon of climate change, which is mainly related to the increase of air pollutants in the atmosphere, is one of the most prominent examples in this regard. Climate change is any change in the climate component such as temperature, precipitation and wind that occurs over many decades. The use of energy carriers is a major contributor to the emission of air pollutants and thus affects climate change. Climate change also has costs for different sectors of the economy, which increase energy consumption from its examples. Since Iran has been exposed to severe climate change in recent years and energy consumption in its various economic sectors has risen and is one of the most important countries in the field of air pollutants emission, in this study, Investigating causality The interactions between climate change and energy consumption in different economic sectors are addressed. For this purpose, temperature and precipitation data and energy consumption of 28 provinces have been used for the period 1370 to 1395. To investigate the two-way causality between climate change and energy consumption, the Toda-Yamamoto causality method, which is an adjusted Var, is used. The estimated results showed that during the studied period, there is no causal relationship between climate change and energy consumption in the main sectors of Iran's economy, and there is only one-way uncertainty about temperature on energy consumption in the agricultural sector and energy consumption in the domestic and commercial sectors, And also for provinces with higher than average temperatures there is a stronger and more bilateral causality between energy consumption and climate change variables (temperature and precipitation), and on the other hand, increasing energy consumption increases the amount of 〖co〗_2(carbon dioxide) in the atmosphere
