This research investigates the potential of utilizing recycled concrete aggregate (RCA) and recycled sand (RS), derived from crushed concrete cubes, as sustainable alternatives in construction materials. The study comprehensively evaluates the properties of RCA and RS, focusing on workability, impact resistance, abrasion resistance, and compressive...

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...

Monitoring Sustainable Development Goals (SDGs) has mainly focused on levels of achievement of targets and indicators, but few studies have examined policies and implementation efforts systematically. The Sustainable Development Solutions Network (SDSN) has called for more monitoring of policy efforts, which is necessary to understand why overall...

The 17 Sustainable Development Goals (SDGs) broadly cover the social, economic and environmental dimensions of sustainable development. Achieving one target will affect the achievement of others through their intrinsic linkages, either positively or negatively. Achieving the SDGs requires an integrated approach. Existing knowledge on SDG...

This is the Editorial of the first IGES-initiated Special Feature of the Sustainability Science journal. This Special Feature on Just and Sustainable Transitions in Net-Zero Asia aims to highlight how researchers, policymakers, and practitioners across Asia are applying just transition thinking to address pressing environmental challenges, climate...

This study delves into the patterns of urban expansion in Kabul, using Landsat and Sentinel satellite imagery as primary tools for analysis. We classified land use and land cover (LULC) into five distinct categories: water bodies, vegetation, barren land, barren rocky terrain, and buildings. The necessary data processing and analysis was conducted...

This is part of the report for the 1st period (May 2022 to August 2023) of Project for the Development of Integrated Coastal Ecosystem Management System in the Republic of Mauritius, a JICA Technical Cooperation project. The work aimed to understand the current status of ecotourism and the potential of introduction of mangrove ecotourism in...

　北九州市は、市内の温室効果ガス（GHG）排出削減目標を掲げるだけでなく、アジア地域への貢献目標も掲げている。それは、アジア地域で、2050年までに、2013年度の市内のGHG排出量の150％以上に相当する排出量の削減を目指す（以下、「150％削減目標」という。）というものである。環境国際協力に長年取り組んできた「世界の環境首都」として、気候変動対策のようなグローバルイシューにも市内外で積極的に貢献していく姿勢を見せている。 　本稿は、北九州市の「150％削減目標」の意義や、その目標達成に向けたアプローチを確認した上で、政策効果の「見える化」の方法論について検討を行った。「150％削減目標」が数値目標であることを踏まえ、北九州市の取り組みのうちGHG排出削減量を把握できそうなものを特定し...

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...
