Triple bottom line analysis of the decline in foreign tourist demand in Japan due to the Covid‐19 pandemic
This study developed a consumption‐endogenous input–output analysis framework and a novel counterfactual structural decomposition analysis (SDA) framework to assess the economic, social, and environmental effects of the 2020 decline in foreign tourists due to the COVID‐19 pandemic. The results show a pandemic‐induced loss of 33 million tourists, resulting in 3.44 trillion JPY in value‐added losses, employment declines for 868,976 people, and envi…
Impact of air pollution on human morality
This study aimed to investigate whether global air pollution harms human morals beyond physiological and psychological health. To accomplish this, we conducted an original survey involving over 80,000 individuals across 30 countries, inquiring about their recent perceived unethical behaviors. Through regression analyses, we identified global evidence of a positive correlation between local monthly average concentrations of nitrogen dioxide (NO 2 …
Firm heterogeneity in sources of changes in CO2 emissions from international container shipping
Inclusive wealth footprint for cities in Japan
A generalized framework for analyzing car lifetime effects on stock, flow, and carbon footprint
This study proposes a new framework for estimating the effects of changes in the physical lifespan (PHL) of cars and the possession lifespan (POL) of new and used cars on stock, flow, and carbon footprint (CF). Applying this framework to all new and used cars registered in Japan from 1990 to 2016 showed that a 10% extension of the PHL of cars reduced the CF of cars by 30.7 Mt, while a 10% extension of the POL of new cars reduced the CF of cars by…
Material efficiency for climate change mitigation
Decomposition of toxicity emission changes on the demand and supply sides
This study investigated the changes in the toxicity of chemical emissions from the US industrial sector over the 1998-2009 period. 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 result…
Linking Local Consumption to Global Impacts
Forecasting Replacement Demand of Durable Goods and the Induced Secondary Material Flows
The aim of this article is to propose a method for forecasting future secondary material flows by combining a product lifetime distribution analysis with a waste input‐output analysis and present a simple case study of automobiles. The case study demonstrates that the proposed method enables us to estimate replacement demand of new vehicles, number of end‐of‐life (EOL) vehicles arising from the aging of vehicles, volume of shredder scraps recover…
CO2 emission clusters within global supply chain networks
Trends in Japanese households' critical-metals material footprints
This study adopts the concept of material footprint (MF), an indicator for consumption-based material extraction via international trade, and identifies the relationship between the MFs of critical metals for low-carbon technologies – neodymium, cobalt, and platinum – and Japanese household consumption through a multiregional input–output approach using the global link input–output model. We focus solely on the impact of changes in consumption pa…
