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...

Transition to a sustainable net zero society is an urgent task, and if it is to be achieve, it will be essential to have the participation of citizens who are responsible for climate damage and emission reduction. Climate citizens’ assemblies have been held mainly in Europe since around 2019. A climate citizens’ assembly is a meeting where...

The circulating and ecological sphere (CES) concept promotes a self-reliant decentralised society by utilising regional resources to achieve decarbonisation. The concept is particularly relevant to depopulated areas across Japan facing a continuous increase of underutilised agricultural land that brings environmental, social and economic challenges...

北九州市は、市内の温室効果ガス（GHG）排出削減目標を掲げるだけでなく、アジア地域への貢献目標も掲げている。それは、アジア地域で、2050年までに、2013年度の市内のGHG排出量の150％以上に相当する排出量の削減を目指す（以下、「150％削減目標」という。）というものである。環境国際協力に長年取り組んできた「世界の環境首都」として、気候変動対策のようなグローバルイシューにも市内外で積極的に貢献していく姿勢を見せている。 本稿は、北九州市の「150％削減目標」の意義や、その目標達成に向けたアプローチを確認した上で、政策効果の「見える化」の方法論について検討を行った。「150％削減目標」が数値目標であることを踏まえ、北九州市の取り組みのうちGHG排出削減量を把握できそうなものを特定し...

EUとドイツのエネルギ－転換と水素戦略：ガイヤーEU議会議員（独・社会民主党）にロシアのウクライナ侵攻後の動向を聞く

Coastal social-ecological systems (SES) are essential for the wellbeing of coastal communities and the wider society. However, in many parts of the world coastal SES face rapid change, and ultimately degradation. In this paper we unravel the mechanisms and implications of change in coastal SESmobilising multiple sources of knowledge, including...

Study region: Bosten Lake (Xinjiang, China). Study focus: This paper mainly focuses on quantifying changes in water storage of Bosten Lake using multi-mission satellite data. From Landsat images, we firstly extracted the lake area changes between 2003 and 2022 with the help of the modified normalized difference water index (MNDWI); Secondly, we...
