global warming is one of the major concerns in environmental issues. its effects are being exposed faster than anticipated recently. it causes adverse ecological and socioeconomical effects. the 4th assessment report issued by the u. n.’s intergovernmental panel on climate change (ipcc) states that it is appropriate to define global warming was caused by greenhouse gases due to human activities...

The extensive and close economic linkages among different regions of China have effects not only on regional economic growth, but also on CO2 emissions and carbon leakage among regions. Taking Beijing as a study case, we constructed MRIO models for China’s 30 provinces and municipalities for 2002, 2007 and 2010, to measure the embodied CO2 emissions in the interregional trade of China on region...

This study estimates the extent to which embodied CO2 emissions are increased or reduced when a socioeconomic structural change occurs. Embodied CO2 emissions were estimated by input-output models (I-O models) and a general equilibrium model (GE model), and the respective results were compared. The embodied CO2 emissions differ greatly depending on the assumptions of the total system. The embod...

We calculate CO2 emissions embodied in China’s net exports using a multi-regional input-output database. We find that the majority of China’s export-embodied CO2 is associated with production of machinery and equipment rather than energy-intensive products, such as steel and aluminum. In 2007, the largest net recipients of embodied CO2 emissions from China include the EU (360 million metric ton...

This study investigated lifecycle CO2 (LCCO2) emission reductions through application of double-window casement systems (DWCS) in residential units in Korea, compared with conventional single windows (SWs). The DWCS is a double window system that is energy-efficient, reducing energy consumption during operation. However, this system incorporates increased embodied CO2 emissions. We evaluated LC...

A high-quality carbon dioxide (CO2) inventory is the cornerstone of climate change mitigation. Most of the previously reported embodied CO2 inventories in China have no more than 42 sectors, and this limitation may introduce apparent inaccuracy into the analysis at the sector level. To improve the quality of input-output (IO)-based CO2 inventories for China, we propose a practical energy alloca...

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 g...

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-CO2 greenhouse gas (GHG) emissions for China in 2012. The non-CO2 GHG emissions, which cover CH4, N2O, HFCs, PFCs, and SF6, amounted to 2003.0 Mt. CO2-eq (including 1871.9 Mt. CO2...

This study examines the annual CO2 emissions embodied in China’s exports from 2002 to 2008 using environmental input–output analysis. Four driving forces, including emission intensity, economic production structure, export composition, and total export volume, are compared for their contributions to the increase of embodied CO2 emissions using a structural decomposition analysis (SDA) technique...
