The GHGs emissions by different activities show that the main part that is 25% belongs to electricity and heat production and the industrial activities counting as 21% of total emission. About 37% of the electricity consumption in Europe belongs to manufacturing and share of industrial activities in GHGs are among 30% to 40%. The electricity production trends show that the proportion of the renewables energy is going to reach to 20% in Europe by 2020 and according to the new energy targets, the minimum use of renewable energy must be 27% by 2030 and decarbonizing by 2050. For the industrial sector as a main energy consumer several elements affect the total energy consumption that start from the mining of the raw materials, transporting the materials to factories, grid network and finally the product to the end users and landfilling/recycling the used products. In this regards, to analyse all factors together a new multi-objective dynamic model has been developed. Moreover, to achieve eco-factories, the main solutions have been provided and dynamically analysed by the model. The results show that, all possible factors must be considered at the same time and applying just some approaches such as solar panels and forgetting the other factors such as end user, life cycle analysis and many other factors will not achieve the sustainability goals. The multi-objective dynamic models can be used as an appropriate approach to check the role of all solutions in achieving eco and sustainable factories.
