Carbon emissions in buildings are classified into two main types; embodied carbon and operational carbon. Operational carbon refers to emissions which occur during the operational phase of a building. Embodied carbon is fuel related and process related carbon emitted during material extraction, transportation, manufacturing, distribution, construction, disposal and reuse. Creating zero carbon projects, where the operational carbon is reduced to zero, has become the latest trend which enables the possibility for embodied carbon to increase simultaneously. Therefore, in order to reduce overall emission levels, estimating and managing embodied carbon emissions in buildings is of paramount importance. Currently, there are several embodied carbon estimating databases, methods and tools available. However, the accuracy of these embodied carbon estimates developed using these secondary data sources is quite questionable. Hence, the study aims at developing an accurate methodology for estimating embodied carbon using the value chain concept and blockchain technology for construction supply chains.

Initially, a comprehensive literature review is carried out followed by conceptualising and testing an accurate method on estimating embodied carbon incorporating the value chain concept for construction supply chains. Selection of a case study on a land development project is used as the primary case study to estimate embodied carbon using the developed conceptual method of estimating embodied carbon. Later on, this EC estimate is compared with other estimates prepared using the existing databases, methods and tools. Subsequently, data modeling is carried out, which leads to development of the prototype blockchain system to estimate embodied carbon. Subsequently, the developed blockchain-based system is tested and validated through case studies and expert forum.

The ultimate research outcomes of the study are developing an accurate methodology to estimate embodied carbon in construction supply chains and a prototype blockchain system that estimates embodied carbon.
