Abstract: Based on the AHP low-carbon economy evaluation index system, this paper evaluates the developing status of Shandong''s low-carbon economy pointing out that city people''s behavior and low-carbon economic development are closely related. And we try to use theory of planned behavior as guidance for the purpose of analyzing the necessity of regulating the behavior of urban residents. At the same time, we put forward some feasible suggestions from the aspect about how to make residents behavior normative to promote the development of low-carbon economy. [Copyright &y& Elsevier]

Abstract: In response to the national energy-saving and emission-reduction policy, the development status of iron and steel industry in Shandong province has been investigated in this paper. On this basis, the existing problems were analyzed and carbon emission coefficients method was used to calculate the carbon emissions in Shandong''s iron and steel industry in 2005-2008. The result indicated that the carbon emissions showed upward trend overall in 2005-2008 and there were still spaces for cutting down carbon emissions. Finally, according to the above analysis, the carbon emission reduction approaches were proposed, including improving the technical equipment and equipment capacity, optimizing process, decreasing iron-steel ratio and optimizing energy structure. It is essential for the relevant governments to make scientific and rational decision-making and further to lay a theoretical foundation for realizing the target of sustainable and low-carbon economic development in Shandong''s iron and steel industry.

Abstract: Allowing for global warming, low carbonization is the hotels’ inevitably choice. Based on investigation conducted among high-star hotels in Ji’nan, this paper calculates the carbon footprint of catering products in these hotels during operation. The conclusions are as following: (1)The carbon footprint of catering products in high-star hotels during operation is mainly generated in the direct source of carbon emissions, accounting for over 99%. (2)All of the carbon emissions from indirect sources correlate to reception scale. However there is a wide gap among them: according to the carbon emissions per unit of catering product from the consumption of electricity among the six hotels, the highest one is 25 times as the lowest one. (3)Among the six hotels, there is a gap on the carbon footprints per unit of catering product, the highest one is 5.56 times as the lowest one. (4)The higher rank of hotels and the more characteristics of catering products, the more carbon footprints. © 2011 Published by Elsevier Ltd.
