Embodied energy use in China's infrastructure investment from 1992 to 2007: calculation and policy implications.

Liu H, Xi Y, Ren B, Zhou H - ScientificWorldJournal (2012)

Bottom Line: We also use the structure decomposition model to analyze the factors impacting the embodied energy use in infrastructure investment for the same time period.The results show that embodied energy use in infrastructure investment accounted for a significant proportion of China's total energy use with an increasing trend and reflect that improper infrastructure investment represents inefficient use of energy and other resources.Some quantitative information is provided for further determining the low carbon development potentials of China's economy.

ABSTRACT
Infrastructure has become an important topic in a variety of areas of the policy debate, including energy saving and climate change. In this paper, we use an energy input-output model to evaluate the amounts of China's embodied energy use in infrastructure investment from 1992 to 2007. We also use the structure decomposition model to analyze the factors impacting the embodied energy use in infrastructure investment for the same time period. The results show that embodied energy use in infrastructure investment accounted for a significant proportion of China's total energy use with an increasing trend and reflect that improper infrastructure investment represents inefficient use of energy and other resources. Some quantitative information is provided for further determining the low carbon development potentials of China's economy.

Mentions: During the last three decades, China's remarkable economic growth not only has enabled it to achieve social progress, but also has been accompanied by a corresponding surge in energy use (Figure 1). Although China has successfully declined its energy intensity (energy consumption per unit gross domestic product) by 67% from 1980 to 2010, it is now the world's largest energy consumer and biggest emitter of carbon dioxide (CO2), the chief greenhouse gas (GHG) [1]. Hence, China is facing immense energy related pressures and challenges, such as energy supply shortage, high foreign dependency for oil, massive acid deposition, and growing international pressure about GHG emissions reduction [2, 3].
