Abstract:The importance of greenhouse gases control conducted in environmental impact assessment on construction project is discussed in confronting climate change. The greenhouse gases emissions assessment indexes comprise of basic indexes including annual emissions quantity of greenhouse (ton/year), unit production greenhouse gases emissions metric (ton/ton production) and unit industry increase value of greenhouse emissions metric (ton/10,000 RMB) and the optional indexes consisting of comprehensive energy consumption (ton standard coal/year), unit production energy cost (ton standard coal/ton production), unit industry increase value energy cost (ton standard/Yuan). The basic and optional indexes are employed in the environmental impact assessment indexes of construction projects including thermal power, steel and cement. The basic indexes should be selected for other industries. The results of case study indicates that indexes are effective and valuable for greenhouse gases control adopted in environmental impact assessment of construction project to confront climate change in China.
