A Structural Decomposition Analysis of China’s Consumption-Based Greenhouse Gas Emissions

The trends of consumption-based emissions in China have a major impact on global greenhouse gas (GHG) emissions. Previous studies have only focused on China’s energy-related consumption-based emissions of CO₂ or specific non-CO₂ GHGs without taking overall consumption-based non-CO₂ GHG emissions into account. Based on a constructed global non-CO₂ GHG emissions database, combined with CO₂ emissions data, this paper fills this gap through an examination and analysis of China’s GHG emissions using a global multi-regional input−output (MRIO) model for 2004, 2007 and 2011, and identifies the major factors driving changes in consumption-based emissions through a structural decomposition analysis (SDA). The results show that compared with CO₂ emissions, CH₄, N₂O and F-gases emissions all increased more rapidly. Among consumption-based non-CO₂ GHG emissions, investment-based emissions experienced the fastest growth, but the net exports of non-CO₂ GHG emissions dropped drastically in recent years. While investment in total final consumption demand is the most influential factor for CO₂ emissions, household consumption most significantly affects the growth in consumption-based non-CO₂ GHG emissions.
