Taking a multi dimensional perspective of economic development, carbon dioxide,industrial pollutant emission and resource consumption in the case study of Shenyang City, the resource consumption and environmental impact in the process of urban economic development and low carbon transition were analyzed. The emission reduction potential and scenario of various technologies were evaluated. The results showed that the city played a key role in global low-carbon economic construction, and emission reduction technologies in urban scale can reduce total amount of carbon emission in substantial degree. From the aspect of future development, the input of technology and economic growth pattern should be strengthened to realize economic development and total amount reduction of pollutant emission.
