Environment consumption patterns of Chinese urban households and their policy implications

In the last two decades, sustainable consumption has become one of the most important issues in global sustainable development. Rapid economic development in China has greatly improved people's living standards, but has also seriously damaged the environment. In this paper, material flow analysis and life-cycle assessment methods were used to analyze environmental consumption patterns of Chinese urban households. Results show that the total household environmental impact (HEI) increased nearly four fold, increasing from 1.85 in the environmental potential index (EPI) in 1985 to 6.40 EPI in 2000. In 1985 and 1990, more than 80% of HEI came from food and housing consumption behaviors. In 2000, transport and housing consumption behaviors have become the main sources of HEI. Climate, economic development, household income. family size, and urbanization rate are main driving forces of household environmental impacts. The increasing consumption demand in the next two decades and its environmental implications are discussed in the last part of this paper.
