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 rapid growth in microplastic pollution research is influencing funding priorities, environmental policy, and public perceptions of risks to water quality and environmental and human health. Ensuring that environmental microplastics research data are findable, accessible, interoperable, and reusable (FAIR) is essential to inform policy and...

Agricultural certification schemes are increasingly requiring concession holders to prevent deforestation when they develop plantations but do not sufficiently address forest restoration, which is necessary to prevent further biodiversity loss. This policy brief recommends, by focusing on palm oil, that agricultural certification schemes strengthen...

Japanese companies have pioneered the development of a large number of low-carbon technologies (LCTs). As a rapidly expanding economy with burgeoning energy requirements, India offers a significant potential market for Japanese LCTs. The industry sector in India accounts for a significant share of commercial energy use and hence carbon dioxide (CO2...

This mini review describes the current status and challenges regarding institutionalisation of wastewater surveillance systems against COVID-19. Monitoring SARS-CoV-2 in wastewater has been proposed to be a potential tool to understand the actual prevalence of COVID-19 in the community, and it could be an effective approach to monitor the trend...

The global hospitality industry is at a pivotal juncture, confronting a pervasive challenge — the menace of plastic pollution and marine litter. The Global Tourism Plastics Initiative (GTPI) notes that approximately 80 percent of all tourism activities occur in coastal areas, positioning the hotel industry as a significant contributor to the...

Enhancing capacity for building resilient cities is a growing concern among policy makers and international communities to minimize the impacts of climate change and natural disasters. The UN Conference on Sustainable Development 2012 and the Sendai Framework for Disaster Risk Reduction (2015–2030) called for urgent need in building resilient...

As with past Global Environment Outlooks (GEOs), once the current state of the environment and policy response is assessed, it is important to look at possible policy pathways to a more sustainable future. With recent developments at the international level in late 2015, namely the adoption of the Sustainable Development Goals (SDGs) and the Paris...

　地方自治体の職員が日々実践していることは、ほぼSDGsだろう。住民のあらゆる困りごとに対してなんらかの対応をしつつ、将来を見据えた自治体のビジョン・ロードマップの策定および施策の立案・実践を行っているからだ。 　それなのになぜ、地方自治体に対してSDGsが求められているのだろうか。この小論では、小生なりのSDGsに関する理解と都市計画・まちづくりに関する国内の好事例について紹介する。 ・自治体を含むマルチステークホルダーで作られていったSDGs ・SDGsと都市のグローバルな動き ・自治体SDGs先進国の日本と都市計画・まちづくり：富山市、さいたま市、ニセコ町の事例 　富山市、さいたま市、ニセコ町の担当者にお話を伺ったところ...
