In the context of economic globalization and production fragmentation, the boom in intermediate and processing trade has made EEIT (emission embodied in international trade) accounting and the recognition of its responsibility more and more complicated, and the drawbacks of traditional gross value statistics more and more conspicuous. The rapid development of global value chain theory in recent years has given rise to a decomposition framework of the trade flow in a country’s export, based on the global value chain, which offers new methods to study EEIT and allocate its responsibility. The combination of global value chain accounting and EEIT research can offer new ways to research EEIT transfer and allocate its responsibility. Utilization of this technique can help understand each country’s “common but differentiated responsibility” in emission reduction. Finally, aiming at the knowledge gaps in current analysis, this paper attempts to discuss the trends, and possible challenges, in research on EEIT, and its responsibility based on the global value chain theory.
Industrial restructuring is a significant measure for low-carbon transition. In principle, carbon emissions can be effectively reduced by limiting the output of high-emission sectors; however, the socio-economic effects of the sectors should also be considered. Moreover, owing to the limitations of the method or data, the interactions between households and production sectors have been neglected in the study of industrial restructuring, resulting in an incomplete and potentially biased understanding of the role of households. To fill this gap, we applied a semi-closed input–output model to identify key sectors by economic and emission linkages and measure the employment impacts (direct, indirect, and induced) of reduced carbon emissions. The empirical results for China in 2010–2018 showed that relatively small changes in key emission sectors would significantly affect the economic growth, and reduced carbon emissions reduction would generally lead to high job losses. Promoting labor-intensive sectors, particularly the service sector, is conducive to achieving a “multi-win” situation for economic development, carbon emission reductions, and stable employment. Furthermore, our results highlight the significance of households: expanding consumption and increasing household income can bring multiple benefits, such as economic growth, job creation, and low carbon emissions. These findings can provide useful information for identifying the optimized path of restructuring and helping achieve the sustainable development of the environment, economy, and society.
Energy issues are closely related to the development of human society and economy. Embodied energy is the total direct and indirect energy consumption required for the production of goods and services. In the context of the intensifying development of economic globalization and prosperity of international trade, embodied energy is considered as a better indicator to comprehensively reflect the nature of a country’s energy use than the direct energy use. The development of trade in value added (TiVA) accounting and global value chain theory has brought new ideas to embodied energy research. This study applies TiVA accounting to the study of embodied energy and establishes a complete framework to decompose the sources, destinations, and transfer routes of embodied energy in a country’s exports, and comprehensively depicts the embodied energy flows in China’s exports at the country and sector levels as an instance. The results show that China exports large amounts of embodied domestic energy use, and export is an important factor for the rapid growth of China’s energy and emissions. At the country level, the United States and EU28 are traditional major importers of China, and developing countries, such as Brazil, India, and Indonesia, are emerging markets. China’s embodied energy flows to different importers vary in terms of trade patterns, flow routes, and the embodied domestic energy intensities. At the sector level, the light industry and the services create more benefits, whereas manufacturing, such as chemicals and metal products, consumes more energy, and there is a mismatch between the main sectors that create economic benefits from exports and the main sectors that consume energy for exports. These results indicate that embodied energy of China’s exports has a great impact on global energy consumption and carbon emission, and the optimizing of China’s export embodied energy structure is conducive to global energy conservation and emission reduction. This article strongly suggests the importance of the global value chain decomposition framework in embodied energy research.
A comprehensive assessment of the environmental and employment impacts of international trade is essential for coordinating sustainable development between the economy, environment, and society. International trade is an important driving force for global economic growth. However, the environmental and social impacts of trade under global value chains (GVCs) have not yet been comprehensively characterized. This study aims to estimate the impacts of international trade from 2000–2014 on carbon emissions and employment using the gross export decomposition method, incorporating a counterfactual method based on the multi-region input–output model. We found that (1) at the global level, international trade has been conducive to carbon emission reductions since 2003 and played a role in increasing employment throughout the study period; however, the impacts of GVC-related trade have been mixed, generating global emissions savings, but leading to job losses. This implies that there is a trade-off between carbon emission reduction through GVC embedding and employment creation. (2) At the national level, a country’s participation in international trade benefits the environment, employment, or both. In this sense, international trade is no longer a zero-sum game; rather, it is likely to be a positive-sum game for all participants regarding environmental benefits and job creation. (3) In bilateral trade, developed and developing economies have positive and negative impacts, meaning that they should take joint actions to balance environment–employment–trade growth. These findings are useful for determining the responsibilities of different countries toward climate change and achieving sustainable development of the economy, society, and environment.
