Introduction
Book and claim is a chain of custody model in which the flow of administrative records representing
specified characteristics is not necessarily connected to the flow of physical material or product through
the supply chain. Transferrable instruments with entitlement to claim (TIECs) are administrative records
issued in a book and claim system to represent and track the ownership of specified characteristics, separate
from the associated material or product. TIECs can be retired to support owners’ claims of consumption or
use of specified characteristics. The book and claim model is often suitable where material or product with
specified characteristics cannot, or only with difficulty, be kept physically separate from material or product
without specified characteristics, such as renewable power in an electricity grid which also has power from
non-renewable sources, or multiple sources of renewable and non-renewable natural gas feeding into a
common pipeline network.
There is a market need for book and claim. Book and clai

Introduction
Formatted: Font: Bold
Book and claim is a chain of custody model in which the flow of administrative records representing specified
characteristics is not necessarily connected to the flow of physical material or product through the supply
chain. Transferrable instruments with entitlement to claim (TIECs) are administrative records issued in a
book and claim system to represent and track the ownership of specified characteristics, separate from the
associated material or product. TIECs can be retired to support owners’ claims of consumption or use of
specified characteristics. The book and claim model is often suitable where material or product with specified
characteristics cannot, or only with difficulty, be kept physically separate from material or product without
specified characteristics, such as renewable power in an electricity grid which also has power from non-
renewable sources, or multiple sources of renewable and non-renewable natural gas feeding into a common
pipeline network.
There is a market need for book and claim. Book and claim can be useful to help organizations participate in,
and support, the utilization of more sustainable solutions, even when those solutions are not part of the
organization’s own direct operations. For example, book and claim can be used to help incentivize investment
in activities that reduce greenhouse gas emissions in a defined system that includes multiple companies,
industries and regions, by conveying a unique right to claim the associated reduced emissions characteristics.
Book and claim is used under the market-based approach for imported electricity in corporate greenhouse
gas reporting.
The purpose of this document is to serve a wide range of sectors. This document provides a common method
to apply the book and claim model and aims to enhance transparency throughout the value chain that utilizes
this model. The common methodology and enhanced transparency ensure that any claims supported by book
and claim can be clearly understood by all value chain actors and the consumer. The credibility of a particular
book and claim application can be enhanced by the methods of verification of claims.
