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...
Since the 26th Conference of Parties (COP26) of the United Nations Framework Convention on Climate Change (UNFCCC) in 2021, global society, including Asian countries, has entered the phase of how to implement a long-term transition roadmap to net-zero greenhouse gas emissions (GHGs). Given vital needs for the development in many Asian countries, a...
This report aims to build a better understanding of status quo and prospect of methane mitigation in oil and gas sector of Japan. The related policies and practices, which have been taken or considered by the national government, industrial association and major companies, are reviewed and summarized accordingly. A short summary is also provided...
本稿は、環境省から受託した「令和4年度国際脱炭素化社会研究調査等委託業務」の業務報告書である。
本業務では、東アジア地域において、先行して導入されている排出量取引制度の動向とその効果等の調査・分析を行った。具体的には、中国と韓国の2か国を対象とし、これまで実施された業務で既に収集済みの情報を基に、2022年度の最新情報を含む基礎的情報の収集を実施した。そして、排出量取引制度に関する各国の取組の進展、とりわけアジア地域における制度の状況等を踏まえ、日本・中国・韓国の3か国の政府機関・研究機関等と協力して、第7回日中韓カーボンプライシングフォーラムを開催した。本フォーラムでは、排出量取引制度を含むカーボンプライシングに関する各国の経験の共有や、各国で運用されている制度上の課題と解決策、さらには今後の協力について議論した。
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...
As an invited presentation, this document gives a summary about regulation and management system for air pollution and control in China. Actions taken for air pollution control since 2013 are elaborated and the achievements in air quality improvement are summarised. Experiences, challenges and the way forward are also shared for discussing the...
Focusing on methane mitigation of oil and gas industry, this presentation gives an overview about policy progress on this issue in Japan and ASEAN. The good practices of related industries are summarised. The policy options are proposed and future potential for the cooperation between Japan and ASEAN are analysed accordingly.
This presentation was given at the 11th congress of the Asian Association of Environmental and Resource Economics, which was held on August 19-20, 2022. In spite of a much wider scope of the submitted paper for this conference, the presentation solely focuses on the Chinese national emissions trading scheme (ETS) to avoid the overlap with the other...
Developed from an IGES working paper and based on the information gathered by hearing interviews to local experts and policy practitioners, this presentation explains the position of national emission trading scheme (ETS) in climate policy mix of China and the milestones for the development of this policy. The policy design features are analysed...
