An Analysis of Carbon Emissions in Building Demolition
Carbon emissions have been implicated in building demolition projects, and the most significant contributors include concrete, brick, wood, and glass. Around 70% of demolition waste in China is from construction and demolition waste (CDW) (Liu et al., 2020; Elshaboury et al., 2022). This country is the most significant contributor to CDW. It is then followed by Europe, with 870 million t, and the United States, with 485 million t (Wang et al., 2022).
China
In a comprehensive review of carbon emissions by Liu et al. (2020), the researchers recommended that the following should be considered: technological issues, regional disparities, and temporal differences. The research primarily centers in Xiancun, Guangzhou. The study segregates activities into four distinct sectors: Demolition, transportation, landfill management, and recycling facilities, in alignment with the various phases comprising the life cycle of demolition waste. The study revealed that the activities of each of these sectors have significant carbon emissions.
Europe
Various countries in Europe contributed to the increased carbon footprint. In Britain in 2021, academic
