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
