Cities play a crucial role in regional sustainable development through trade linkages with surrounding economies. This study extends the inclusive wealth (IW) conceptual framework for footprint analysis, offering a comprehensive production–consumption perspective to measure regional sustainability. We empirically analyse the IW footprint for 1880 m...

Analyzing the sustainability of a city requires consideration of external impact. Footprint analysis has been widely used to analyze external spatial impact by consumption. We incorporate production-based wealth data and a high-resolution multi-regional nested input-output table (MRNIO) to calculate ecosystem service footprints consistent with phys...

The increasing frequency of large-scale natural disasters generates massive energy and resource demand for recovery. We developed an inoperability multiregional input–output model as a quadratic programming model with production and greenhouse gas (GHG) restrictions to develop a low-carbon recovery plan for natural disasters. In a case study of a h...

Climate change is causing a range of impacts on communities such as more frequent extreme weather, air pollution, changing distribution of infectious diseases, mental health impacts and others. The 2018 report of the Lancet Countdown on health and climate change concluded that "…climate change is the biggest global health threat of the 21st century...

It has been observed that market failure has hampered the development of sustainable forest ecosystem services such as CO2 absorption and fixation, water retention, and biodiversity. One of the reasons for this is that the link between forest land use and the beneficiaries of that use has not been widely recognized or clearly established. To addres...

On 3 April 2020, the Director-General of the WHO stated: “[COVID-19] is much more than a health crisis. We are all aware of the profound social and economic consequences of the pandemic (WHO, 2020)”. Such consequences are the result of counter-measures such as lockdowns, and world-wide reductions in production and consumption, amplified by cascadin...

Understanding environmental and social footprints at the city level through multiregional input-output (MRIO) analysis is a key to designing policy aimed at mitigating the direct and indirect impacts of a city economy on sustainability. However, since the quantity of data required is substantial, compiling city-level MRIO tables in Japan and updati...

Over the past few decades, Thailand has been one of the highly open economies and one of the most successful countries in applying the export-led growth model. At the same time, carbon dioxide (CO2) emissions released in Thailand tripled between 1990 and 2015. To examine how international trade plays a role in shaping Thailand's CO 2 emissions inve...

Reducing food waste and food loss generated through the whole food supply chain has, in actuality, become a global requirement. A Sustainable Development Goal (SDG) aims to ensure sustainable consumption and production patterns. The government in a nation strives efforts to reduce the amount of the wasted edible food to achieve the SDG target. This...

This study assesses the regional energy mix potentials of Japan for maximised renewable electricity generation and reduced CO2 emission intensity in the electricity sector, in view of the nationally determined contribution (NDC) mitigation target, and the 2 °C rise limit target. Beginning with the deregulation of the retail electricity market, disc...

City carbon footprints have become an important tool for monitoring the progress of cities towards lowering their greenhouse gas emissions and contribution to climate change. Cities usually source a major part of their natural resource demand from their local, national and global hinterland, and cause emissions across the whole global supply chain...

This paper assesses to what extent CO2 emissions from electricity in the residential sector can be further reduced in Japan beyond its post-2020 mitigation target (known as “Intended Nationally Determined Contribution (INDC)”). The paper examines the reduction potential of electricity demand and CO2 emissions in the residential sector by conducting...

This study conducted a comparative assessment and a meta-analysis of 48 greenhouse gas (GHG) emissions reduction scenarios based on bottom-up energy system analyses for 2030 reported in seven studies published between 2011 and 2015 to obtain insights into the ambition level of Japan's official mitigation target for 2030. First, the scenarios were c...

Achieving global greenhouse gas (GHG) mitigation goals will rest heavily on the performance of national climate and energy policies in Asia. This chapter surveys the climate policy landscape in China, India, Japan and Indonesia to understand the prospects of reaching globally shared climate goals. The survey links the effects of milestone climate a...

The chapter identifies the risks and costs related to renewable energy investments in general and then analyses the risks and returns associated with renewable energy investment using Yokohama as a case study. The role of the government in setting clear policy targets, in providing financial support, and in introducing new and innovative policies p...

This study examines how a carbon tax could affect industrial-related carbon dioxide (CO2) emissions in Japan. Rather than forecasting the effects of a tax, the paper employs a time-series autoregressive moving average (ARMA) model to determine how past subsidies and fuel price changes affected investments in energy and carbon intensity in Japan’s i...

This chapter examines the economic impact of low-carbon investment on renewable energy sectors in Yokohama via an input–output analysis. The renewable energy sector is aggregated into five detailed categories: solar photovoltaics (PV) residence, solar PV non-residence, hydropower, wind, and other (biomass and others). Two main findings are presente...

This book presents several case studies on green infrastructure in Asian countries, that is, China, India, Japan, and Indonesia. The following methodologies were utilized: risk analysis, cost–benefit analysis, integrated assessment modelling, input–output analysis, and comparative analysis. Cities are central to achieving low-carbon development tar...

The 11 March 2011 Fukushima Daiichi nuclear disaster will forever be remembered as a once-in-a-lifetime tragedy. The changes to Japan's energy system following Fukushima may nonetheless leave future generations with a more sustainable legacy. A growing body of literature hypothesizes that transitions like this one have the potential to reshape Japa...
