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...

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 report, which focuses on innovation, is the third by The World in 2050 (TWI2050) initiative that was established by the International Institute for Applied Systems Analysis (IIASA) and other partners to provide scientific foundations for the UN’s 2030 Agenda for Sustainable Development. In 2018, the first report by TWI2050 on Transformations...

Asia and the Pacific’s unrelenting industrial development has been a driving force in the economic growth of scores of countries in the region and beyond. This shift has led to greater prosperity, increased urbanization and sustained population growth. Yet as the region has become the “world’s factory”, it is increasingly realizing not only the...

G7 recently released a 36-page communique on their plan to achieve net-zero emissions. It reinforces the demand for critical minerals and lays out the future agenda for critical minerals. Critical minerals are essential for deployment of renewable energy technologies that help us fight climate change. It is time G20 chalks its own critical minerals...

10月26日に行われた、菅内閣総理大臣の所信表明演説で「2050年脱炭素社会の実現」を目指すとした方針についての、IGESコメントです。 脱炭素化の方向性と時間軸を明確に示すことは、企業や投資家の長期的視点に立った経営・投資判断を支えることにつながります。また、2050年脱炭素化は、パリ協定が目指す1.5℃目標にも整合する非常に野心的な目標で、総理大臣自らが2050年脱炭素化社会の実現を宣言したことをIGESは大いに歓迎します。 一方で、新型コロナウイルスによって減速した日本経済の立て直しに向けた経済復興策は、欧州における「欧州グリーンディール」のような、経済刺激策を気候変動やその他の環境課題への対策と結び付ける対策が乏しく、令和3年度予算編成におけるグリーンディールの作り込みが急務です。...

This is the final report of the city-to-city collaboration between EU cities (including one from the UK) and Japanese cities under the International Urban and Regional Cooperation (IURC) Asia and Australasia. During 2021-2023, thirteen EU cities (including one UK city) from ten countries and ten Japanese cities participated in the project and...

Maldives has had to face a growing challenge in managing its solid waste and associated environmental, economic and social issues. This situation is even worse in small islands due to the size of the island communities, insufficient infrastructure and waste transportation difficulties, absence of sufficient budget and appropriate cost recovery...

Just like in any city, the waste management has always been a major societal issue for Phnom Penh. The monthly amount of disposed waste at the landfill more than doubled in the past decade owing to factors such as population growth, economic growth, changes in industrial structure and of people’s lifestyle. While Phnom Penh Capital Administration...
