Embodied Carbon of Buildings: Tools, Methods and Strategies

Abstract

Embodied carbon can be defined as the “CO2emissions produced during the extraction of resources, transportation, manufacture, assembly, disassembly and end-of-life disposal of a product”. Calculation of the carbon footprint of buildings is important to promote the construction of low-carbon buildings that release significantly less CO2compared to conventional buildings. However, researchers and practitioners in this area tend to disregard the embodied carbon and pay more attention to the operational carbon when calculating the carbon footprint of buildings. This paper reviews the current state and trend of research on the embodied carbon of buildings with focus on the tools, methods and strategies employed and makes recommendations for future research direction.
