"Structural Decomposition Analysis of Consumption-based CO2 Emissions in Major Economies during 2007-2023 " Authors: Homma, Takashi, Teruhisa Ando, Miyuki Nagashima and Keigo Akimoto Abstract This study estimates consumption-based CO2 emissions across major economies from 2007 to 2023 and evaluates the drivers of emission changes using structural decomposition analysis (SDA), based on multi-regional input-output (MRIO) tables. The differences between consumption-based and production-based emissions reveal emissions embodied in international trade by region and by sector. We use the Asian Development Bank Multi-Regional Input-Output (ADB-MRIO) database, which provides continuous time series including the COVID-19 pandemic period, with IEA CO2 statistics. We decompose emission changes into three factors: emission intensity, intermediate input structure, and final demand effects. This decomposition identifies components related to emission reduction. A sensitivity analysis comparing results with the GTAP database for the benchmark year (2017) evaluates the robustness of findings across different data sources. The study provides updated evidence on consumption-based emissions using the latest available data and offers policy implications for decarbonization in major and global economies. |
