Conference Proceeding
As the climate crisis worsens, the nexus between security considerations and climate is attracting both policy and academic attention. Despite its socio-political importance, the significance of considering climate change from a security and diplomatic perspective has not yet been fully explored in the policy arena and on-the-ground actions. The...

鉄鋼業、化学工業、窯業・土石製品や航空・海運部門は「排出削減が困難なセクター」と呼ばれています。素材産業では製造過程で大きなエネルギーを必要とし、原料に化石燃料が利用されていることなどから、再生可能エネルギーや代替原料の利用などによる排出削減の取り組みが進められています。また、これらの産業の脱炭素化を加速するには、技術開発だけでなく、代替製品の利用や使い捨ての削減など、社会全体の需要側の対策も必要です。航空・海運部門でも近年2050年ネットゼロを目標に、代替燃料の開発が進められていますが、コストや持続可能性の面で実装に向けてさまざまな課題を抱えています。  本特集では、これら排出削減が困難なセクターにおける削減シナリオ、技術開発の現状と課題、ビジネスの事例などを紹介いただき...

Discussion Paper
India’s national government has offered strong support for the development of green hydrogen as part of the clean energy transition. However, much of the actual progress in this transition will depend on subnational governments. This paper argues India’s subnational governments have significant potential to capitalise on diverse natural resource...
German-Japan Energy Transition Comission, The Second Young Scientists Dialogue
This research aims to develop a framework to explore scenarios which are compatible with the global 1.5°C climate target. This entails explorations of socio-economic scenarios, as well as technological assumptions on energy systems, which can be supported by stakeholders at the same time satisfying an emission benchmark. First, we set up three...
Conference Paper
Technical Report
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...
Technical Report
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。
Book Chapter
In Hydrogen in Decarbonization Strategies in Asia and the Pacific
This chapter explores the interest in hydrogen adoption across Asian countries for achieving net-zero goals, with a particular focus on Japan's prominent role. While Japan has taken strides in hydrogen initiatives, the extent to which its strategy aligns with ambitious climate targets remains uncertain. The chapter emphasises the importance of...
