Based on data from 2007 input-output tables for each province, we estimated the energy embodied in China’s interprovincial trade through input-output analysis. The results show that a sizable transfer of energy is embodied in China’s interprovincial trade, and the transfer goes from the central and western provinces, which have higher energy endowments, to the eastern and coastal provinces, which have more developed economies. The provinces with the greatest net inflow of embodied energy via interprovincial trade were Zhejiang, Guangdong, Beijing, Shandong, and Jiangsu. The provinces with the greatest net outflow of embodied energy were Inner Mongolia, Shanxi, Shaanxi, Xinjiang, and Heilongjiang. To effectively reduce China’s energy consumption, it is vital to adhere not only to the producer responsibility principle but also to the consumer responsibility principle. In particular, the economically developed provinces with substantial net inflows of embodied energy in interprovincial trade should provide support to the provinces from which the embodied energy outflows come.

In recent year, Korea relies on imports for most of the iron ore, the main raw material of rebar, resulting in CO2 pollution with lots of energy consumption. Hereupon, this study carried out the research on the energy consumption and CO2 emissions of the recycled rebar using the wasted steel from building demolition. For that, this study worked out the energy consumption and CO2 emissions in the process of generation, transportation and production of wasted steel and, on the basis of which, it conducted the comparative study with virgin materials. The major research results are as follows: First, the energy consumption and CO2 emissions of the recycled rebar were found to be highest in the process of its production at 89.2% and 85%, respectively. In addition, in the comparison between recycled rebar and virgin material, the former was found to be most advantageous in energy consumption. On the contrary, as for CO2 emissions, the recycled rebar showed a 88.3% reduction possibility of greenhouse gas (GHG) emissions comparing to statistics of input-output analysis based on competition inducement coefficient, but it was found to be more disadvantageous from the perspective of GHG reduction than the statistics of input-output analysis based on non-competition inducement coefficient.
