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...

Different baseline endowments and circumstances among countries, including local events, have resulted in disparities in energy policy and status. Differences in energy status have caused countries to make various decisions, but with the implementation of grid interconnections, some countries elected to plan the development of their energy sector...

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...

Focusing on four major ASEAN member states, including Indonesia, Viet Nam, Thailand and the Philippines, this paper reviews the current status, and identifies the gaps and prospects for achieving a high penetration of renewables for energy transition in ASEAN. These four countries have been leading renewable policies in this region and have...

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...

Japan has adopted several policies that signal its intent to rely on hydrogen to achieve net-zero climate goals. However, many of those same policies are unclear about its support for a transition to green hydrogen. Relying on gray and blue hydrogen without a transition to green hydrogen will harm the climate. It will also result in several other...

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...

農地において支柱を立てて上部空間に太陽光発電設備を設置し、下部空間では営農を継続しながら発電を行う営農型太陽光発電（ソーラーシェアリング）は、再生可能エネルギー導入量の拡大が見込めること、農業者の収入拡大による農業経営の改善や6次産業化の推進も期待できることから、政府として推進する方針が掲げられ、様々な制度で導入促進が図られている。 例えば、再生可能エネルギーの導入促進のために固定価格買取制度が導入されているが、営農型太陽光発電と野立太陽光発電で買取価格が区別されていない。しかしながら、両者は費用構造や事業リスクが異なり、導入によってもたらされる便益も異なることから、その性質に則して営農型太陽光発電の推進のための施策が導入されることが望ましい。...

This paper examines the effects of financial incentives, particularly electricity prices, on residential solar photovoltaic system installations. We shed light on the importance of a factor that has been largely overlooked in the literature on the adoption behavior of low-carbon building technologies: the distinction between retrofit and new-build...
