Abstract
Embodied carbon (EC) has emerged as a pressing issue in the building sector, with a focus on achieving the 2050 net zero carbon target. Accurate estimation of EC requires extensive data inputs, policies, and standards from the global construction supply chains. Although various tools exist for computing EC in the building sector, they largely rely on secondary data from users and environmental product declarations, raising concerns about the accuracy of the estimates. Critics argue that the construction industry needs to focus on adopting emerging digital technologies (EDTs) to improve the accuracy of EC estimation. This study aims to investigate state-of-the-art current literature on the use of EDTs in embodied emission estimation of the construction industry. Using preferred reporting items for systematic reviews and meta-analyses, a systematic literature review was conducted on government reports, journal articles, and conference publications from the last five years (2017–22). The study focused on five EDTs – blockchain, machine learning, building information modelling, digital twin, and Internet of things – to analyse their potential adoption for improving the accuracy of EC estimation. The research community has attempted to address the limitations of existing tools by utilizing salient features of the EDTs, and the study highlights four key performance features – accuracy, traceability, transparency, and efficiency – that have contributed to the development of the EC tool. The study concludes that the usage of EDTs has proven to be effective in overcoming certain limitations, but more research is required to develop commercially viable tools using EDTs. The authors critically evaluate the building sector’s contribution to achieving the United Nations Sustainable Development Goal 13 of ‘climate action’, highlighting the need for the construction industry to adopt emerging technologies to improve EC estimation accuracy and contribute to global sustainability efforts.
