截至2011年,我国建筑总面积达400多亿平方米,以每万平方米建筑施工过程中产生建筑废渣500吨至600吨推算,400亿平方米建筑面积至少产生了20亿吨建筑废渣。据推算,到2020年我国将新增建筑面积约200亿平方米,届时将新增至少10亿吨建筑废渣。而建筑物所贡献的温室气体占总排放的15%,比各种交通工具所排放的总合还多出1.5%,再加上传统建筑方式对资源和能源的恣意消耗和巨大浪费,中国城市化进程中所付出的生 As of 2011, China’s total building area reached more than 40 billion square meters, accounting for 500 tons to 600 tons of construction waste generated per 10,000 square meters of building construction. At least 40 billion square meters of construction area produced at least 2 billion tons of construction waste. It is estimated that by 2020 China will add about 20 billion square meters of building area, will add at least 1 billion tons of construction waste. The greenhouse gas contributed by the buildings accounts for 15% of the total emissions, which is 1.5% more than the total emissions of various modes of transport. Coupled with the unconscionable consumption of natural resources and energy and the huge waste of traditional construction methods, The students pay for the process
