Efficient material design and the use of low-carbon concrete are crucial to efforts to reduce greenhouse gas emissions (GHG) during the construction process, according to a report from C40 Cities, Arup, and the University of Leeds.
Eliminating material waste at the design stage could lead to an 18% reduction of GHG emissions between 2017 and 2050, the report says. The production of cement requires extreme heat and releases a great deal of CO2. The report says that using low-carbon alternatives to traditional cement could cut GHG emissions by 6% between 2017 and 2050.
