Specifically, we employed a multiregional input–output analysis framework and integrated a supply-side index decomposition analysis (IDA) with a demand-side structural decomposition analysis (SDA) to clarify the main drivers of changes in the toxicity of production- and consumption-based chemical emissions. The results showed that toxic emissions from the US industrial sector decreased by 83% over the studied period because of pollution abatement efforts adopted by US industries. A variety of pollution abatement efforts were used by different industries, and cleaner production in the mining sector and the use of alternative materials in the manufacture of transportation equipment represented the most important efforts.. |

The edge betweenness centrality in the global supply chain networks is newly formulated and a relationship between edge betweenness centrality and vertex betweenness centrality is further provided. The empirical analysis based on the world input-output database covering 35 industrial sectors and 41 countries and regions in 2008 shows that specifically, China's Electrical and Optical Equipment sector, which has a higher edge and vertex betweenness centrality, is the most critical sector in global supply chain networks in terms of spreading CO2 emissions along its supply chain paths. We suggest greener supply chain engagement centered around the China's Electrical and Optical Equipment sector and other key sectors identified in this study.. |

Applying the ‘footprint’ concept with a multiregional input–output model, we have quantified the direct and indirect vulnerability of the Japanese economy to such risks. Considering the supply risks associated with primary processors, we find that Japanese final consumers are exposed to relatively higher supply risks for neodymium as compared with cobalt and platinum. Our study shows that the primary processing stage of a metal’s supply chain may contribute significantly to the overall supply risks, suggesting that this stage should be taken into due account in understanding and mitigating supply-chain vulnerability through, e.g. supplier diversification and alternative material development.. |

We apply consumption-based accounting to identify the key sectors responsible for primary carbonaceous PM2.5 mortality. The study combines an input–output model with an atmospheric transport model and fully links consumer demand to final pollutant fate and health impact. We find the following: (1) considering atmospheric transport changes the distribution of demand-induced impact as compared to conventional emissions footprinting, (2) the supply chain paths with the greatest impact on PM2.5-induced human health problems in the region are centered around agricultural technologies in China, and (3) the transportation sector of China plays a major role in the supply chain paths that generate relatively large impacts on human health. We conclude that Japan is responsible for PM2.5 mortality in Asia and should take leadership in changing key high-priority technologies and critical supply chain paths into greener ones.. |

Countries engaged in the development and diffusion of new energy technologies are concerned about steadily importing scarce rare metals. Nevertheless, the question of what kind of competitive relationships exist among demand countries is not well addressed. This study focused on platinum primary product used to produce greener products like next-generation vehicles and analyzed the international trade network complexity of the platinum primary product using the clustering method. From the results, we found that (1) there exit well-separated nine trade clusters (i.e., trade networks with higher exchanges) in the international trade network of 2005, (2) the group including South Africa and the group consisting of Western countries together account for approximately half the total international trade flow in platinum primary products, and (3) international coordination of purchases and sales of platinum among relevant trade partners in the identified largest cluster: South Africa, Russia, Japan, China, Hong Kong, and Switzerland is crucial in securing the stable supply and demand for platinum.. |
