As more solar photovoltaic panels are expected to be introduced globally to promote the stabilization and decarbonization of electricity supply, concerns have been raised about the associated resource constraints and the environmental impacts. To promote circular economy initiatives, this study aims to provide insight into the variables and the con...
Product Service Systems (PSS) have received increasing attention as a means for realizing a circular economy. Although PSS are expected to help mitigate the causes of climate change and slow the consumption of scarce natural resources, there is a risk of unintended consequences, resulting in a net increase in environmental impact. Despite this poss...
Given the effort to reduce greenhouse gas (GHG) emissions, understanding the consumption patterns that facilitate and support changes is essential. In this context, household food consumption constitutes a large part of society's environmental impacts due to the production and solid waste generation stages. Hence, we focus on applying the Life Cycl...
This study analyzes the changes of correlation between donor characteristics and Official Development Assistance in the mitigation sector (mitigation ODA) before and after the 2009 Copenhagen Accord under the United Nations Framework Convention on Climate Change. The study used multiple regression analysis using panel data of 23 countries over 15 y...
This paper presents an approach for assessing lifestyle carbon footprints and lifestyle change options aimed at achieving the 1.5 °C climate goal and facilitating the transition to decarbonized lifestyles through stakeholder participatory research. Using data on Finland and Japan it shows potential impacts of reducing carbon footprints through chan...
The circular economy has potential synergies with climate change mitigation, although quantitative evidence for these synergies in the consumer product sector has not yet been systematically evaluated. We conducted a systematic review of existing studies of consumer-oriented product-service systems (PSS) on the lifecycle impacts, focusing on a meta...
Cities and urban consumers play a central role in the transition to a decarbonized society. Building on existing studies that identify the significant contributions of lifestyle changes, this study proposes a practical methodology for modeling and exploring city-specific carbon footprint reduction pathways through lifestyle changes to decarbonizati...
Since 2015, the international policy community has started to agree on international agreements with ambitious middle-term and long-term goals, highly relevant to sustainable consumption and production (SCP) such as those seen in the Paris Agreement, SDGs, and the plastic-related agreements at the G7 and G20 processes. Along with this trend, there...
Climate science provides strong evidence of the necessity of limiting global warming to 1.5°C, in line with the Paris Climate Agreement. The IPCC 1.5°C special report (SR1.5) presents 414 emissions scenarios modelled for the report, of which around 50 are classified as '1.5°C scenarios', with no or low temperature overshoot. These emission scenario...
Increasing attention is being paid to lifestyles in sustainability research and policymaking. Applying a foresight approach to sustainable lifestyles supports this increased focus by highlighting possible futures while also empowering citizens through a participatory process. Foresight has its origins in theory and practice to serve the policymakin...

Technology foresight is crucial in shaping the futures of social good that brings intrinsic and instrumental values to engage different stakeholders in the process. Within this context, the impact of technological innovation on the society from a multi-dimensional perspective is understudied. This paper addresses and investigates this gap by applyi...
Addressing the prevailing mode of high-carbon lifestyles is crucial for the transition towards a net-zero carbon society. Existing studies fail to fully investigate the underlining factors of unsustainable lifestyles beyond individual determinants nor consider the gaps between current footprints and reduction targets. This study examines latent lif...
This report provides diverse possibilities of the future in 2050 as the basis for discussions on future lifestyles by different stakeholders and citizens in a more participatory foresight process. Based on the outcome of a survey of future-oriented experts, this report gathers insights from experts in diverse fields on a global scale, with both opt...

Sustainable Consumption and Production (SCP) was adopted as a stand-alone goal and reflected as one of the cross-cutting objectives of the Sustainable Development Goals (SDGs), with a central role to address global resource consumption and its associated environmental impacts, as well as numerous social and economic issues. With this broad characte...
2015年に合意された2つの国際的な取り決め、すなわち「持続可能な開発目標(SDGs)を含む持続可能な開発のための2030アジェンダ」と気候変動枠組み条約加盟国による「パリ協定」を踏まえて国際社会が目指す持続可能な社会経済実現の鍵として,「持続可能な消費と生産(SCP)」,とりわけOne Planet Living(地球一個分の暮らし)を目指す取り組みの強化を軸に、国際協力のあり方を再編成することを提案した。とくに、中長期的に目指すべき持続可能な社会を各国や地域社会で実現する取り組みのモデルづくりを支援すること、望ましい社会に向けた進展を測る共通指標を持つこと、さらに多様な取り組みの経験を、先進国と途上国という別を問わずに共有する政策対話のプラットフォームを持つことを提案した。

Bangladesh has emerged as a leading ship breaking nation. We conducted a material flow analysis of steel in Bangladesh with an emphasis on the ship breaking industry (SBI). The total aggregate domestic steel consumption in fiscal year (FY) 2010 was 2,930,000 tonnes (t) in Bangladesh; SBI met approximately 51% of the demand for raw materials and 37%...
SDGs やパリ協定の実施へ向けて開発協力のあり方は大きな転換点にある。SDGs における目標間のトレードオフおよび両合意による大幅な低炭素化・資源効率性の向上という要請を踏まえ、途上国・新興国・先進国それぞれにおいてライフスタイルやビジネスモデルを含めた経済社会と生産・消費パターンの変革が求められている。本論説では、SDGs とパリ協定の達成へ向けた開発協力の今後の展望として、(1)指標の設計、(2)調整・統合された戦略・計画、(2)持続可能な都市やコミュニティのモデルプロジェクト実施、(4)戦略的持続可能性アセスメントの導入に関する4点を提言した。
The mode of the conventional development cooperation is at the turnin...
A material flow analysis (MFA) study was conducted on all materials (including ferrous and nonferrous),
parts, equipment and consumables extracted from the ship breaking industry in Chittagong,
Bangladesh. In fiscal year 2010, a total of 100 large vessels (1.35 million LDT) were dismantled. From this,
1.17 million tons of steel and ferrous material...
Dismantling (or “breaking”) of ships invigorates global shipping by replacing older ships and recycling or reusing as much as 95 % of their materials. Recently, Bangladesh is dominating global ship
breaking. Here, we aimed basically at expounding the inflows of the ship breaking industry (SBI) in Bangladesh from the perspectives of origin, types, a...
Acid Mine Drainage (AMD), high acid water containing heavy metals discharged from mines, not only from the operating ones but also from the already abandoned ones, has been recognized as major cause of mine pollution. In Japan, the government spends billions of yen every year to prevent pollution caused by AMD in about 80 abandoned mines. It is wid...
Acid mine drainage (AMD) from about 80 abandoned or closed mines in Japan are actively treated by neutralization; the government spends billions of yen every year to protect the environment from these discharges, and treatment will have to continue for many years. However, it is difficult to predict the future AMD chemistry, neutralizer requirement...
