In 2005，“the 11th Five-Year Plan” for national economic and social development first called for the binding quantified energy saving target for 2010 based on 2005，with the unit GDP energy consumption decreased by 20%. As the quick advance of China’s industrialization and urbanization，due to the concentration of urban population and economic activities，the energy consumption and greenhouse gas emissions became increasingly prominent. The effectiveness of urban energy saving plays a crucial role to achieve the national energy saving target. In this paper，based on an overview of the status and characteristics of urban energy consumption，the progress and effects of conserving energy and reducing emissions in key cities，during the Eleventh Five-Year Plan，will be comprehensively investigated，while，the target and route to further promote urban conserving energy and reducing emissions in the Twelfth Five-Year Plan will be put forward.
