  Current patterns of production and energy consumption depend heavily on combustion of fossil fuels. All the services and commodities produced in an economy are related -- directly or indirectly -- to energy consumption and therefore to the emission of air pollutants such as carbon dioxide (the main cause of greenhouse effect and climatic changes). Generally speaking, the amount of CO2 emission depends on such factors as CO2 intensity, energy intensity, interactions between and among economy sectors, production-technology nexus, and the structure and level of final demand for the commodities of different sectors. The aim of this article is to identify the interactions between productive activities of the country’s industries in a given period of time (year 2001), intensity of energy consumption by these activities, and the resulting environmental impacts (specifically CO2 emissions). To this end, the input-output approach has been used to formulate a model for the calculation of the energy vector and CO2 intensity of industries so that one can rank industries by their level of pollution. The findings of the present article can be used for policy making regarding energy conservation, pollution control, and choice of appropriate production technique(s) for industries, considering environmental impacts. Furthermore, suitable prices could be set to control the final demand for the products of more pollutant sectors and thereby control air pollution with CO2.   Manuscript profile

  One of the  method to recognize  key sectors allocation resources  priority in the the economy, is using Input-Output Table. Identifying the key sectors of the economy prevents from inadvertent investments and leads to deliberate economic activities and proper prioritization for allocating the limited resources. Tourism industry, as an important economic sector, is composed of various subsectors which plays a  crucial role in the economic growth and employment. In this paper, With  Using an input-output model  we identified key sectors  in Tourism Industry and its  impacts on the economc growth. Based on  production elasticities among sectors as a measurement instrument, the findings suggest investment in the key sectors of tourism industry including road transport, libraries and museums, rail transport, and water transportation in order to achieve higher level of economic growth.In other hand, based on employment and income elasticities, transport services and water expansion as a key sectors were identified.
