Decomposition analysis of carbon emissions and water consumption of urban manufacturing industry: a case in Dalian, China

摘要

This paper aimed to identify the effect factors of carbon emissions and water consumption of urban manufacturing industry with Dalian city of China as a case study. We selected 29 Dalian manufacturing industrial sectors, and collected the statistical data of energy and water demand from 2006 to 2010 to calculate the carbon emission intensity and water consumption. All of these 29 industry sectors could be grouped into three industrial types of labor-intensive, capital-intensive and technology-intensive industries. The carbon intensity and water intensity during this period were calculated, and LMDI (Logarithmic Mean Divisia Index) method was used to identify the effects of economic output, industry structure, carbon intensity (or water intensity) on the total carbon emissions (or water consumption) from Dalian manufacturing industry. The results showed that economic output is the main driving force of increase of both total carbon emission and total water consumption, while optimization of the manufacturing industrial structure will contribute to reduce both of them.
