Carbon Auditing
Abstract:
The construction industry has an indispensable role in global carbon reduction as it is one of the largest
generators of carbon footprint emissions. Of various emission sources at different stages of the construction life
cycle, construction materials and products contribute a considerable proportion, and thus their importance should
not be neglected. Although multiple carbon certification or labelling schemes for Construction Materials and
Products (CMPs) have been launched to assess their carbon emissions, such efforts and practices still rely heavily
on traditional centralized data storage and publishment, which suffer data non-transparency and manipulation
problems, making it difficult to identify and track carbon footprints of CMPs. Therefore, this paper proposes a
transparent and reliable carbon auditing framework for CMP certification based on blockchain technology, which
aims to facilitate the management of carbon footprints ranging from raw material extraction, transportation to
plants, and manufacturing. In the proposed framework, a two-level privacy blockchain data model summarizing
carbon footprints is first developed under data transparency and privacy concerns. An asymmetric encryption
scheme integrating with an online document-sharing system, the InterPlanetary File System (IPFS), is then
proposed to secure data storage and access during the carbon auditing process. Besides, smart contracts are
developed to interact with the blockchain network, which supports generating immutable distributed ledgers of
construction material and product carbon footprints. A prototype using Ethereum, a public blockchain
development tool, was deployed and evaluated. The feasibility of the framework is validated through an illustrative
example, showing that the blockchain-based framework is a promising solution in auditing and tracking the carbon
footprints of CMPs.
