This book introduces the Eora, Global Trade Analysis Project (GTAP), and World Input-Output (WIOD) databases, providing detailed metadata on their sources, structures, and construction techniques. It explains how multi-regional input–output (MRIO) databases are utilized to calculate consumption-based accounts, guiding the reader through mathematical steps and equations. The text illustrates that various MRIO databases yield different national consumption-based CO2 accounts, emphasizing the need for analysts to understand the accuracy of these databases when used in climate policy-making. The mathematical equations behind each technique are thoroughly explained, and a link is provided to access specially prepared MATLAB functions. To facilitate meaningful comparisons, the three MRIO databases are mapped to a consistent classification system of 40 countries and 17 sectors. The aggregation effect is shown to be minimal, ensuring that the aggregated databases accurately reflect the full-sized versions. The book concludes with recommendations for constructing future MRIO databases and their application in policy-making. Endorsements highlight the book's clarity and significance for practitioners and scholars engaged in multiregional input-output analysis, noting its contributions to understanding uncertainties in carbon footprint analysis and its relevance for ongoing global sustainability assessments.
