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...

Transitioning to the Enhanced Transparency Framework (ETF) under the Paris Agreement (PA) from the current measurement, reporting and verification (MRV) arrangements under the United Nations Framework Convention on Climate Change (UNFCCC) requires developing countries to enhance their national reporting systems in a sustainable way. There are...

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...

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...

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 objective of this paper is to identify relevant indicators and highlight the current availability of data to support collection of indicators for measuring and evaluating transparency capacity under the GST. It is fair to question, why after all these years of international capacity-building do many countries, particularly developing countries...

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...

This study analyzes the changes of correlation between donor characteristics and Official Development Assistance in the mitigation sector (mitigation ODA) before and after the 2009 Copenhagen Accord under the United Nations Framework Convention on Climate Change. The study used multiple regression analysis using panel data of 23 countries over 15...

T7 Policy brief: Task Force on Wellbeing, Environmental Sustainability, and Just Transition As the world’s most developed economies, the Group of Seven (G7) countries play a crucial role in leading the transition to net-zero, which necessitates the use of critical minerals (CMs) in various clean energy applications. However, the growing demand for...

本分析では、100%という最大限の再生可能エネルギー（以下、再エネ）比率を想定した状況下において、送電線や電源などの電力系統内に揚水式水力、貯水池式一般水力発電、地熱発電、バイオマス発電、家庭用ヒートポンプ式給湯器、系統に接続される電気自動車（EV）の蓄電池、水素製造装置、既存ガス火力発電を改修した水素専焼火力といった電力需給調整に必要な柔軟性 (Flexibility) を供給する能力（以下、柔軟性供給力）がどのように利用されるかを明らかにする。 そのために、系統電力需要量に対応する電源構成において、国内再エネ由来の電源が実質的に100% となるシナリオを含む6つのシナリオ（RE60海外水素、RE100、RE100α、RE90α、RE100β、RE90β）を構築した...
