Global concerns of the effects of increased carbon dioxide emissions have pushed policy makers to adopt strict emission targets .The introduction of such targets will require strategies to achieve them in efficient ways. In Qatar, the world highest per capita carbon emitter, stationary emission sources are responsible for the majority of the country's footprint. Concentrated in industrial parks or clusters emissions cuts would be more significant and efficient to achieve as part of a national emission reduction strategy. Conventional mitigation techniques involve fossil fuel replacement, increasing energy efficiency and the use of carbon capture and sequestration. This research proposes an alternative method based on utilization or conversion of carbon dioxide within the industrial city. Carbon dioxide can be chemically or biologically converted into fuel, polymers, food supplements, fodder or another value added product could be used in applications of enhanced oil and gas recovery. Based on concepts of classical network design and Industrial Ecology (IE), a systematic approach was developed to obtain a cost-optimal network of carbon reduction. The integrated analysis of utilization options together with the capture, separation, compression and transmission of carbon dioxide will be required to determine the most economically attractive footprint reduction solutions. The optimization was illustrated using a case study.
