『Abstract
For greenhouse gas (GHG) emissions by the Chinese economy in
2007 with the most recent statistics availability, a concrete
inventory covering CO2, CH4,
and N2O is composed and associated with an
input-output analysis to reveal the emission embodiment in final
consumption and international trade. The estimated total direct
GHG emission amounts to 7456.12 Mt CO2-eq
by the commonly referred IPCC global warming potentials, with
63.39% from energy-related CO2, 22.31% from
non-energy-related CO2, 11.15% from CH4 and 3.15% from N2O. Responsible
for 81.32% of the total GHG emissions are the five sectors of
the Electric Power/Steam and Hot Water Production and Supply,
Smelting and Pressing of Ferrous and Nonferrous Metals,
Nonmetal Mineral Products, Agriculture, and Coal
Mining and Dressing, with distinctive emission structures.
The sector of Construction holds the top GHG emissions
embodied in both domestic production and consumption, and the
emission embodied in gross capital formation is prominently more
than those in other components of the final consumption characterized
by extensive investment in contrast to limited household consumption.
China is a net exporter of embodied GHG emissions, with emissions
embodied in exports of 3060.18 Mt CO2-eq,
in magnitude up to 41.04% of the total direct emission.
