Assessment of CO2e emissions of building materials

The industry of building materials whose carbon emissions are huge is viewed as an important part in National Economy. Its total energy consumption lags behind the metallurgical and the chemical, which ranks third. The carbon emissions of building materials were made up of the direct carbon emission and the indirect carbon emission. The carbon emissions of the raw materials and building materials´ producing process are the two important parts to evaluate the direct carbon emission. Indirect carbon emission which was generated from the depreciation of equipments and buildings, the management in each link and the environmental process of garbage processing and transportation should be estimated.
