Beschreibung: Reliable inventory information is critical in informing emission mitigation efforts. Using the latest officially released emission data, which is production-based, we take a consumption perspective to estimate the non-CO 2 greenhouse gas (GHG) emissions for China in 2012. The non-CO 2 GHG emissions, which cover CH 4 , N 2 O, HFCs, PFCs and SF 6 , amounted to 2003.0 Mt CO 2 -eq (including 1871.9 Mt CO 2 -eq from economic activities), much larger than the total CO 2 emissions in some developed countries. Urban consumption (30.1%), capital formation (28.2%) and exports (20.6%) derived approximately four fifths of the total embodied emissions in final demand. Furthermore, the results from structural path analysis help identify critical embodied emission paths and key economic sectors in supply chains for mitigating non-CO 2 GHG emissions in Chinese economic systems. The top 20 paths were responsible for half of the national total embodied emissions. Several industrial sectors such as Construction, Production and Supply of Electricity and Steam , Manufacture of Food and Tobacco and Manufacture of Chemicals and Chemical Products played as the important transmission channels. Examining both production-based and consumption-based non-CO 2 GHG emissions will enrich our understanding of the influences of industrial positions, final consumption demands and trades on national non-CO 2 GHG emissions by considering the comprehensive abatement potentials in the supply chains.
