With the deepening of globalization and the accelerated transfer of international supply chains, developing countries, such as China, have become global manufacturing centers, which has significant impact on global distribution of CO₂ emissions. In the present study, we quantitatively estimate CO₂ emissions transfer embodied in trade for 141 countries and regions in 2004 and 2014 and the impact on CO₂ emissions in China by using the multi-regional input-output (MRIO) model. Results show that CO₂ emissions embodied in global dramatically increased during 2004—2014 due to further strengthening of trade activities among the countries. In 2014, CO₂ emissions embodied in global trade was 4244 million tons, accounting for approximately onequarter of the total global emissions. As the center of CO₂ emissions transfer embodied in trade, the net transfer of CO₂ emissions embodied in export in China increased from 1200 million tones to 1462 millions in 2014, accounting for 28% and 34% of global carbon transfers. In China, CO₂ emissions embodied in the export sector have concentrated in energy-intensive and carbonintensive industries, while those embodied in the import sector concentrated in low-energy-consuming industries such as services and light industry. Thus, in the context of the global supply chain transfer and China's "dual carbon" goals, to reduce CO₂ emissions, China should actively advocate to establish a global carbon emission accounting framework based on the production-consumption joint responsibility, to ensure fair and reasonable allocation of emission rights. At the same time, China should optimize the export trade structure, accelerate transformation of low-carbon economy, and improve energy efficiency. In addition, it is necessary to strengthen international cooperation, establish effective communication and collaboration platforms, and make positive contributions to global CO₂ emissions reduction and climate governance.
