Tele-connecting regional carbon inequality in China to global consumers

Abstract

Global trade may lead to unequal distribution of CO2 emissions and economic benefits among countries. While regional carbon inequality within a country driven by specific foreign consumers is rarely discussed. Taking China as an example, this study constructed a nested MRIO table to trace the CO2 emissions & value-added flows between each province of China (30 in total) and 18 other countries/regions, and measured the provincial carbon inequality based on emission terms of trade (ETT), emission-value (EV), carbon-Gini coefficient indicators triggered by these global consumers. Here we show that most provinces are net emission exporters and almost half of China's provinces suffered both environmental and economic losses in international trade. What is worse, it triggered severe regional imbalance of emissions and economic gains within China. The less developed western provinces with high emission intensity are always at a disadvantage in international trade, but some eastern provinces are on the favorable side. The consumption of the EU caused the most severe carbon inequality among provinces. These findings provide further information to relieve trade-induced carbon inequality at a refined scale and give inspiration to build more equitable trading mechanisms globally.
