Although the suburbs of numerous cities worldwide are shrinking, research on how to address suburban decline remains scarce. This paper explores participatory mapping in shrinking suburbs as a tool to articulate knowledge co-creation between local officials and communities to inform planning decisions. The paper argues that participatory planning...

本レポートは、世界平均気温の上昇を産業革命前と比べて１.5℃以内に抑えるという目標の達成に向けて、2050年までにカーボンニュートラルを実現するだけではなく、累積排出量をできる限り小さくする観点から、日本国内で早期に大幅な温室効果ガス（GHG）排出量削減を果たす可能性を検討し、その実現のためのアクションプランをまとめたものである。 2024年4月2日更新 謝辞の追記、出典の追記、誤記の修正を行いました。 企業の方向けに使いやすく再構成した「 1.5℃ロードマップ - 脱炭素でチャンスをつかむ。未来をつくる。 」もご活用ください。

This report examines the feasibility of Japan not only achieving carbon neutrality by 2050, but also making significant reductions in greenhouse gas (GHG) emissions, so as to make its cumulative emissions as small as possible, thereby contributing to the global goal of limiting the average temperature increase to below 1.5°C compared to the pre...

This chapter provides the most recent policy frameworks for sound material-cycle society (SMCS) and promoting the 3Rs (reduce, reuse, and recycle) as well as circular economy transition in Japan, with some illustrations of the best practices carried out by the private sector and Japanese local governments as outcomes.

This report includes an analysis of the level of awareness of the SDGs, as well as the progress made in addressing the five SDG Goals (thematic themes) that the UN Global Compact focuses on: Goals 5 (gender equality), 8 (work and human rights), 13 (climate change) and 16 (anti-corruption), and Goal 12 (sustainable consumption and production), which...

Information and Communication Technologies (ICT) have been identified as potential enablers for alternative forms of sharing surplus food to prevent food loss and waste. Food sharing platforms can also provide an entry point to the sustainability transition by encouraging its users to confront the systemic causes of unsustainable and inequitable...

循環経済（サーキュラー・エコノミー）とは、天然資源採掘や廃棄を最少化しながら付加価値を最大化する経済活動を意味する。これまでの大量生産、大量消費、大量廃棄を前提とした「線形経済」（リニア・エコノミー）に代わり、あらゆる段階で資源の効率的・循環的な利用を図る。本稿は、EU と日本における循環経済の確立に向けた政策に関し、特にプラスチックに焦点を当て、ビジネスチャンスを考察する。2020 年に EU が「新循環経済行動計画」を、日本が「循環経済ビジョン 2020」を公表しており、循環経済は新しい経済モデルとなる可能性が高まる。日本では 2022 年 4 月に「プラスチック資源循環促進法」が施行される。これにより製造業者に環境配慮設計を促す公的認定制度の創設など、循環経済の制度設計が進むなか...

Although many researchers highlight the benefits of Urban Green Spaces (UGS) to city dwellers, understanding of residents’ emotional association with UGS remains an incomplete and exciting area of place research. In this study, we conducted an empirical assessment of residents’ Place Attachment (PA) towards UGS in the Greater Tokyo region. For this...

Between the 1990s and early 2000s, large-scale illegal dumping and improper treatment of medical waste was a common occurrence in Japan, and became a serious social issue owing to the potential human health risk and environmental damage resulting from the waste itself, which could be infectious or contained sharps or chemical and toxic substances...

As more countries witness depopulation, the expansion of High-Speed Rail (HSR) to reach shrinking cities in peripheral regions is renewing the debate on the effects of this infrastructure. This is the case in Japan, a country that continues to extend its highly developed HSR network hoping to curb regional decline. This paper investigates whether...
