Talk Title
Global trade imbalance in terms of energy use and carbon emissions: Systems embodiment perspective

Talk Abstract
 

With the rapid movement of communication and transport, nearly all the nations and regions have been integrated into the global economy. As an extension of our previous works, this study combined typical statistical data (statistics of primary energy exploitation, and direct CO2 emissions for 2012 world economy) to explore the global energy use and CO2 emissions from source to sink via interregional trade and discuss the related trade imbalances, by means of systems embodiment accounting that includes the indirect feedbacks associated with both intermediate and primary inputs. Energy embodied in intermediate trade is around five times as much as that in final trade. In intermediate trade, the five leading net importers of embodied energy are Japan, the United States, Mainland China, South Korea and Italy, while the five leading net exporters are Russia, Saudi Arabia, Qatar, Iran and Australia. In final trade, the five leading net importers of embodied energy are the United States, the United Kingdom, Hong Kong, Japan and Saudi Arabia, while the five leading net exporters are Mainland China, Germany, Netherlands, Belgium and Italy. The United States is positioned as a major sink of energy use in the global market. 79% of the local primary energy resources exploited are used for domestic final consumption. Meanwhile, 57% of the energy embodied in its final consumption originates from primary energy resources exploited in foreign regions. For Mainland China, only 38% of local primary energy exploitation sinks into domestic final consumption. Regarding CO2 emissions, global transfer of embodied CO2 emissions amounts in magnitude to 47% of global direct CO2 emissions. 70% of the global total trade volume of embodied CO2 emissions is related with intermediate trade, and 30% is related with final trade. In intermediate trade, the five leading net importers of embodied CO2 emissions are the United States, Japan, Hong Kong, the United Kingdom and Singapore, while the five leading net exporters are Mainland China, Russia, India, Saudi Arabia and South Africa. In final trade, the five leading net importers of embodied CO2 emissions are the United States, Hong Kong, the United Kingdom, Japan and Australia, while the five leading net exporters are Mainland China, Germany, India, Taiwan and Italy. Mainland China obtains a deficit of embodied CO2 emissions in both intermediate and final trades with EU27, the United States, ASEAN and Japan. The intermediate carbon trade deficit of Mainland China is 1.4 times as much as its final carbon trade deficit. The United States is revealed to gain a surplus of carbon emissions with most of its trading partners in both intermediate and final trades. The intermediate carbon trade surplus of the United States is 1.1 times as much as its final carbon trade surplus. Within the globalized economy, nations and regions are supposed to direct sufficient attention to the resource use as well as emissions embodied in trade and adjust the local industrial structure based on its role in the global supply chain for fulfillment of environment protection as well as sustainable use of natural resources.
