Over the past 30 years of rapid development, industrial parks have been an important sustained resource for economic development in China. However, due to economic yield-oriented policy and deficient scientific planning, excessive resource consumption and environmental pollution caused by industrial activities in industrial parks has led to ecological degradation and loss in the local areas. To respond to this issue, many researchers have focused on studying the overall efficiency of industrial parks from the perspective of metabolism of material and energy and have proposed some methods such as life cycle assessment, system of environmental economic accounting (SEEA), material flow analysis, and emergy synthesis, which indeed have improved the methods of evaluating industrial activities shift from only an economic perspective to a more comprehensive direction. However, these approaches have only focused on the efficiency of industrial activities while ignoring ecological conditions of the local areas. This article addressed this issue by proposing an emergy-ecological footprint hybrid model to show how this method could be applied to demonstrate both the energy metabolism of industrial parks' activities and ecological capacity of the local areas. We took the Shenyang economic technological development area (SETDA) and the Fuzhou Qingkou investment zone (FZQKIZ) as case studies to validate this method. Results showed that although the environmental burden of SETDA was heavier than FZQKIZ, the ecological capacity of surplus for SETDA was also stronger than FZQKIZ, which caused ecological surplus of SETDA compared with FZQKIZ. This study indicated that we should pay more attention to ecological capacity of the local areas surrounding industrial parks rather than only focusing on environmental impacts caused by industrial activities.

This paper examines the GHG emission of industrial process in Shenyang city, in the Liaoning province of China, using the 2006 IPCC greenhouse gas inventory guideline. Results show that the total GHG emissions of industrial process has increased, from 1.48 Mt in 2004 to 4.06 Mt in 2009, except for a little decrease in 2008. The cement industry, and iron and steel industries, are the main emission sources, accounting for more than 90% of the total carbon emissions. GHG emissions in 2020 are estimated based on scenario analysis. The research indicates that the cement industry, and iron and steel industries, will still be the largest emission sources, and the total carbon emissions under the business as usual (BAU) scenario will be doubled in 2020 compared with that of 2009. However, when countermeasures are taken, the GHG emission will reduce significantly. Using more clinker substitutes for blended cement, and increasing direct reduction iron process and recycled steel scraps are efficient measures in reducing GHG emission. Scenario 4, which has the highest ratio of 30/70 blended cement and the highest ratio of steel with recycled steel-EAF process, is the best one. In this scenario, the industrial process GHG emission in 2020 can almost stay the same as that of 2009. From the perspective of regions, cement industry and iron and steel industry accounted for the vast majority of GHG emission in all industries. Meanwhile, these two industries become the most potential industries for reduction of GHG emission. This study provides an insight for GHG emission of different industries at the scale of cities in China.
