The Forest Environment Transfer Tax (FETT), a scheme similar to Payment for Ecosystem Services (PES), was introduced for Japanese forests at the national level in 2019 to address the challenges of climate change and promote management mainly in privately owned forests under the New Forest Management System (NFMS). Given insufficient human and...

Central Asia's semi-arid regions, vital for sustaining vast populations and diverse ecosystems, are under heightened environmental stress. Among these regions, the Tuul River Basin, home to over half of Mongolia's population, characterizes the challenges posed by contemporary environmental shifts. This basin, a hub in Mongolia's socio-economic...

Globally, urbanization constitutes one of the major underlying drivers of global ecological degradation. Hence, deurbanization, i.e., demographic shift from urban to distant rural areas in a way that increases quality of life (QoL), can be one of the key pathways to address this global challenge. In this study, we investigated the contribution of...

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...

Nature-based solutions (NbS) are promising measures for protecting, sustainably managing, and restoring ecosystems as well as addressing societal challenges, including climate change mitigation and adaptation. To consider mainstream NbS for use in disaster risk reduction (DRR) infrastructures, the affected residents’ perception and attitude toward...

兵庫県では2020年度から「ひょうご高校生 環境・未来リーダー育成プロジェクト」を開催しており、 青森県でも昨年度から「青森県から日本・世界の環境・ エネルギー問題を考える地元高校生向けワークショップ」 が始まった。これらは2050年の脱炭素社会の実現に向け、 その担い手となる若手人材の育成を目的とした5～ 6日間の研修プログラムであり、その企画・ 運営にIGES関西研究センターが携わっている。 これまでに兵庫県では延べ25校から104名が、 青森県では6校から32名が参加した。昨今、 気候変動問題をはじめとした地球環境問題に関する教育の充実の必 要性が叫ばれてきており、 そのような市民向けプログラムが各地で開催されるようになってき ているが、高校生を対象とし、...

This report was prepared by the Institute for Global Environmental Strategies (IGES) under the International Tropical Timber Organization (ITTO) project "Analysis of Timber Legality Assurance Systems and Good Practices in China and Viet Nam for Sustainable Timber Trade''. This ITTO project was made possible by funding from the Japanese government...

As decarbonisation of the power sector is essential to achieve Japan’s target of net-zero greenhouse gas (GHG) emissions by 2050, it becomes crucial to address how the electricity system incorporates short- and long-term variability in the power output via renewable energy. In this paper, we developed six scenarios for 100% renewable energy in...
