Reassessing the embodied carbon emissions in China's foreign trade: a new perspective from the export routes based on the global value chain

A new route perspective measure based on the global value chain (GVC) distinguishes the embodied emission transfer destinations while concurrently considering the transfer process and GVC embedding position. This study applies this measure to reassess the characteristics of China's foreign trade embodied emissions and their impacts on global emissions. The results show that: (1) China's domestic embodied emission exports are mainly concentrated in manufacturing and dominated by final goods exports and simple GVC routes. China primarily imports foreign emissions via simple GVC routes. (2) The embodied emission intensity of China's exports is much higher than that of its imports, and China's expansion in imports indirectly promoted global emission reduction. (3) China's foreign trade increases global emissions with a waning trend, while GVC-related trade reduces global emissions. Additionally, it is feasible to reduce global emissions by adjusting China's bilateral trade structures with different countries. We conclude that China's GVC-related trade has increased, but exports through complex GVC tend to be the resource-input type. We emphasize that China needs to actively participate in globalization and upgrade its GVC to step off the low-end locking predicament in global production and cope with the multiple pressures of global and domestic emission reduction and stable development.
