Existing greenhouse gas (GHG) emissions reporting tools are static, based on PDFs and spreadsheets, and are not suitable for visualizing and tracing emissions information through complex supply chains. Without a high level of accuracy and traceability, climate disclosures will not be useful for a company or consumer trying to purchase low-carbon products. The objective of this brief is to define the opportunity and propose a path forward to transform climate disclosures by introducing a blockchain-based technical architecture that will more comprehensively track and trace emissions throughout supply chain operations.
