Abstract
China's manufacturing sector faces pressure to reduce its carbon emissions embodied in foreign trade, yet the influence of the sector's structural and path characteristics on reducing embodied carbon emission (ECE) remains unclear. We developed a research framework to analyze the trade-embodied carbon transfer networks of China's 11 manufacturing industries with 48 economies from 2000 to 2019, identifying the key carbon transfer-in industries and paths. By integrating network characteristics, we assessed the ECE reduction pressure on key manufacturing industries and identified factors hindering its decline. ECE in China's manufacturing foreign trade increased by 273.1% from 2000 to 2019, with the ECE in exports to developing countries since 2012 (255.58 Mt) surpassing exports to developed countries (228.31 Mt). China's medium-low and medium-high technology manufacturing are key carbon transfer-in industries, observed large decreases in the importance of the carbon transfer-in paths from Europe, the United States, Japan, and South Korea, versus notable increases from the Row Asia and Pacific region. Metal manufacturing, non-metallic mineral manufacturing, and chemical manufacturing were the top three industries facing ECE reduction pressure. The network structure indicators obstruct the ECE reduction pressure in metal manufacturing, whereas the network path indicators obstruct the pressure in the other key manufacturing industries. To alleviate the ECE reduction pressure within China's manufacturing foreign trade, China's manufacturing sector should enhance trade cooperation with Asia–Pacific countries. The study's insights offer valuable references for China's formulation of domestic manufacturing emission reduction policies and its participation in international climate negotiations.
