High Resolution Image Download MS PowerPoint Slide The mismatch between trade-embodied economic benefits and CO 2 emissions causes carbon inequality, which is seldom analyzed from the intracountry level, especially across a long-term period. This study applied an environmentally extended multiregional input–output model to trace this mismatch and measure the carbon inequality quantitatively within China during 2007–2017. The results show that during the past decade, China’s national carbon inequality was continuously worsening with carbon Gini coefficients rising regardless of production- (0.21–0.30) or consumption-based (0.12–0.18) accounting. The regional carbon inequality was deteriorating, where less developed provinces with 20% of total value-added emitted 32.9% of total CO 2 emissions in 2007, while this figure rose to 42.6% in 2017. The eastern provinces (Jiangsu and Shanghai) had entered into net economic and carbon beneficiaries keeping high trade advantages, by contrast the northwest provinces (Ningxia and Xinjiang) were trapped in a lose–lose situation with trade benefits declining by 68%. The southwest provinces (Yunnan and Guangxi) shifted from being net carbon and value-added exporters to net importers, stepping into the earlier development mode of eastern provinces. This hidden and exacerbated carbon inequality calls for regional-specific measures to avoid the dilemma of economic development and CO 2 mitigation, which also gives a good reminder for the rising economies, like India.
