“…Nansai et al [28] applied a global link input-output model to analyse Japan's carbon footprint. Wiedmann et al [29] and Barrett et al [30] both calculated the UK's consumption-based greenhouse gas emissions and found that consumption-based carbon emissions were rapidly increasing and that there was a widening gap between production-and consumption-based emissions.…”

Abstract:Most of China's CO2 emissions are related to energy consumption in its cities. Thus, cities are critical for implementing China's carbon emissions mitigation policies. In this study, we employ an input-output model to calculate consumption-based CO2 emissions for thirteen Chinese cities and find substantial differences between production-and consumption-based accounting in terms of both overall and per capita carbon emissions. Urban consumption not only leads to carbon emissions within a city's own boundaries but also induces emissions in other regions via interregional trade. In megacities such as Shanghai, Beijing and Tianjin, approximately 70% of consumption-based emissions are imported from other regions. Annual per capita consumptionbased emissions in the three megacities are 14, 12 and 10 tonnes of CO2 per person, respectively. Some medium-sized cities, such as Shenyang, Dalian and Ningbo, exhibit per capita emissions that resemble those in Tianjin. From the perspective of final use, capital formation is the largest contributor to consumption-based emissions at 32-65%. All thirteen cities are categorized by their trading patterns: five are production-based cities in which production-based emissions exceed consumption-based emissions, whereas eight are consumption-based cities, with the opposite emissions pattern. Moreover, production-based cities tend to become consumption-based as they undergo socioeconomic development.

“…15 While hybrid LCA has seen numerous applications, a creative and meaningful deployment of it within decision support analysis to address supply chain issues is generally limited due to a number of factors such as challenges deriving from practical applications (Heijungs et al 2006;Bani et al 2009), methodological challenges (Guinee et al 2010), complexity of SC systems (Suh et al 2004;Deng, Babbitt, and Williams 2011) and usefulness of the results (Nansai et al 2009). 20 Therefore, despite the large number of studies appeared recently, papers published in the field of LCA are more oriented towards the development of techniques, emphasising the need of quantitative methods and overlooking the importance of integration with strategic thinking across the supply chain.…”

“…In order to quantify carbon and material footprints for Japanese households, we clarified the expenditure on commodities by each household (million Japanese yen: M-JPY). The footprint per unit expenditure, or the footprint intensities, was calculated using a global link input-output model (GLIO) (Nansai et al 2009(Nansai et al , 2013a. The GLIO is a MRIO composed of a Japanese input-output structure with 409 sectors of domestic commodities and 409 sectors of imported commodities, and overseas sectors covering 230 countries and regions.…”

Human society consumes a great deal of energy and resources in order to sustain economic activities and promote economic development. In response to the sustained increase in anthropogenic loads on the global environment, environmental footprint analysis has been used to quantify pressures induced by economic activity (Hoekstra and Wiedmann 2014). Footprint analysis is used to identify entire product life cycles Abstract This study simultaneously analyzed the carbon and material footprints for three critical metals (neodymium, cobalt, and platinum) in Japanese households with different income levels. These metals are critical for new energy technologies, such as electric vehicles and rechargeable batteries, and are thus central to carbon footprint reductions. The policy implications of the trade-offs between GHG mitigation and critical metal consumption are considered within the context of differences in income. A global link input-output model representing national and international supply chains was employed to quantify the footprints according to household income quintile. In addition, the square root scaling method was used to compare footprints among households, considering differences in household size and their footprint characteristics. It is found that the degree of similarity among the carbon and material footprints for the three target metals was not very high [Spearman's rank correlation coefficients between them were 0.34 (neodymium), 0.63 (cobalt), and 0.10 (platinum)], implying that differences in relative household demand should be carefully considered based on differences in target footprints. The results of this study were compared to a similar study conducted in the UK to identify similarities and differences among footprints. In both countries, the carbon footprint intensity of household expenditure decreases as household income increases. The findings of this study also revealed that, in contrast to the case of carbon footprints, the material footprint intensities of household expenditure rise as household income increases, particularly in the case of neodymium. Consequently, the implementation of subsidies aimed at reducing carbon footprints and stimulating the economy should carefully consider the concomitant increase in material footprints. Importantly, such considerations are not only applicable to developed countries, but also emerging countries, the living standards of which are expected to increase markedly in the near future.
