Measurement and Decompositiom of Embodied Carbon Emissions in the Export of Electromechanical Products from China to South Korea

This paper uses MRIO model to measure the embodied carbon emissions of China's exports to South Korean electromechanical products in 2005-2014, and uses LMDI method to decompose the overall scale of embodied carbon emissions from electromechanical products exports and the factors affecting carbon emissions from various sub-projects contained in electromechanical products from three aspects: scale effect, structural effect and intensity effect. As a result: 1 The embodied carbon emissions caused by China's export of electromechanical products to South Korea is relatively large, indicating that China bears the carbon emissions of South Korean consumers while conducting trade. 2 China's export of embodied carbon to South Korean electromechanical products showed a trend of first rise and then fall, implying that China's energy conservation and emission reduction policies has played a good role. 3 The scale effect has the highest contribution rate to the export of embodied carbon emissions from China to South Korean electromechanical products and plays a positive driving role. Structure and intensity effect play a reverse inhibition. This means that if China want to lower its embodied carbon emissions from exports and raise its voice in international climate negotiations, it will need to promote a system of world carbon-emissions accountability based on consumer responsibility, at the same time, we will further implement energy conservation and emission reduction policies, adjust the structure of export products, and optimize the structure of energy utilization.
