Trades create a mechanism of embodied CO₂ emissions transfer among regions, causing distortion on the total emissions. As the world¡¯s second largest economy, China has a large scale of trade, which results in the serious problem of embodied CO₂ emissions transfer. This paper analyzes the characteristics of China¡¯s CO₂ emissions embodied in international and interprovincial trade from the provincial perspective. The multi-regional Input-Output Model is used to clarify provincial CO₂ emissions from geographical and sectoral dimensions, including 30 provinces and 28 sectors. Two calculating principles (production accounting principle and consumption accounting principle, ) are applied. The results show that for international trade, the eastern area accounts for a large proportion in China¡¯s embodied CO₂ emissions. The sectors as net exporters and importers of embodied CO₂ emissions belong to labor-intensive and energy-intensive industries, respectively. For interprovincial trade, the net transfer of embodied CO₂ emissions is from the eastern area to the central area, and energy-intensive industries are the main contributors. With the largest amount of direct CO₂ emissions, the eastern area plays an important role in CO₂ emissions reduction. The central and western areas need supportive policies to avoid the transfer of industries with high emissions.
