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。
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...
Working Paper
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...

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...
Working Paper
ADBI Working Paper Series
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。...
Issue Brief
The economic disruptions from the Ukraine war have intensified short term concerns about energy and food security, as well as access to critical minerals. Climate security is also increasingly urgent. This paper urges governments to speed up, not slow down, transitions away from fossil fuels and toward more sustainable development patterns. The war...

Tracking decarbonization effects requires a model for the identification of spatial energy demands on city facilities. However, most developing countries lack detailed discrete time and device-specific energy demand data. In this study, we installed multiple energy demand monitoring systems that could observe electricity demands at the device level...

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...
