"Tele-connect local primary PM2.5 emissions to global consumption" by Meng, Jing Abstract Ambient particulate matter with an aerodynamic diameter of 2.5μm or less (PM2.5) affects visibility, the climate and human health. Policy attention on PM2.5 mitigation is growing worldwide amid the recognition of co-benefits for both environment and health. Primary PM2.5 originates mainly from the incomplete combustion of fossil fuel or biofuel, and industrial processes, burgeoning studies have been conducted on building the PM2.5 emission inventories on global, regional, and country scales. From the territorial perspective, emissions in developed countries, such as Europe and North America decreased since 1960, whereas emissions in Asia increased in the past 50 years, making this continent the predominant emission region. However, relatively few attention has been paid to emissions transferred by international trade. Quantifying the emission leakage is invaluable for addressing the air pollution problem in Asia. In recognition of this gap, consumption-based accounting is used to understand PM2.5 emissions from consumption perspective. The work is based on a global PM2.5 emission inventory and a fully coupled multiregional input–output (MRIO) model constructed from Global Trade Analysis Project (GTAP) database. First of all, we elaborate a production-based PM2.5 emission inventory on the basis of a global fuel consumption data product (PKU-FUEL-2007) and recently published emission factors. The emission sources incorporate 65 combustion sources and 12 material production sources. Then the 65 combustion sources are mapped into the economic sectors according to the sectoral energy consumption data from GTAP V8.1 and International Energy Agency (IEA). Secondly, we link the local primary PM2.5 emissions through the MRIO model and build consumption-based PM2.5 emission inventories (FPr) with 134 countries/regions and 57 industry sectors. Structural path analysis is used to identify the area in supply chain where needed improvements... |
