Book excerpt: Carbon markets involve complex governance challenges, such as ensuring transparency of emissions, facilitating as well as recording transactions, overseeing market activity and preventing abuse. Conventionally, these have been addressed with a combination of regulatory, procedural and technical structures that impose significant burdens on market participants and administrators while remaining vulnerable to system shocks and illicit practices. Distributed Ledger Technology (DLT) has the potential to address these problems. This volume offers the first book-length exploration of how carbon markets can be governed using DLT, offering conceptual and theoretical analysis, practical case studies, and a roadmap for implementation of a DLT-based architecture in major existing and emerging carbon markets. It surveys existing expertise on distributed ledger technology, provides progress updates from industry professionals, and shows how this technology could offer a cost-effective and sustainable solution to double-counting and other governance concerns identified as major challenges in the implementation of carbon markets.
