BACKGROUND• Life cycle carbon;
• Embodied carbon (EC)
• Operational carbon (OC)
• Operational Carbon - Emitted during the operational phase of a building
• Embodied Carbon - Emitted during the production process of a product/service within the system boundaries

RESEARCH PROBLEM
6
• Blockchain
• A decentralized distributed ledger technology
• Enables the records to be stored in blocks
• Maintained on a network of servers called ‘nodes’
• Blockchain Applications
• Level 1 - Cryptocurrencies
• Level 2 - Economic, market and financial applications
• Level 3 - Applications beyond currency, finance and markets
AIM
7
• To develop a methodology for estimating embodied carbon using the value chain concept implemented through a distributed ledger platform for construction supply chains
