This study presents a comprehensive analysis of plastic waste accumulation in both terrestrial and aquatic environments in Can Tho city, Vietnam, a nation with high per capita plastic consumption and significant plastic waste discharge. Focusing on urban residential areas, riverside communities, suburbs, and rural regions, the research investigates...

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.

Rapid economic development has led to an overwhelming surge in waste generation, demanding urgent and comprehensive waste management solutions, particularly in developing countries. Source separation is a critical and indispensable step in integrated waste management and is featured as a government-led pattern in general. However, its...

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...

The 2030 Agenda for Sustainable Development and the Paris Agreement established a strong foundation for the coherent implementation of climate action and sustainable development objectives across all levels and sectors. However, recent global crises, such as climate, energy, the Russian invasion of Ukraine, the coronavirus disease (COVID-19), and...

The International Energy Agency estimates that to hit net-zero globally by 2050, six times more critical minerals will be required in 2040 than today. The rapid increase in demand for critical minerals is likely to increase price volatility. This could aggravate energy security concerns, and thereby delay the necessary clean energy transition...
