Carbon Emissions Analysis of Rock Wool Board Products

Green building materials have drawn more and more attention of the Chinese Government. Carbon footprint research on typical building materials products in China is of great significance to promote the sustainable development of building materials industry and realize the objectives of series actions on carbon dioxide emissions control in China. This paper explores the calculation method for carbon emissions of building materials products by taking rock wool sheet products as an example based on the life cycle idea and the characteristics of China's building materials industry. It also puts forward effective emission reduction suggestions through a comparative analysis of carbon emissions in different stages of rock wool production. The results show that the carbon emissions during the production of rock wool sheet is 1471.77 kgCO2eq/t, in which, the proportion of carbon emissions in the raw materials production stage is the highest, accounting for 58%.
