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...

There is limited knowledge on the potential impacts of electric vehicle (EV) deployment in developing countries to date. India is a rapidly industrializing country with a national policy to promote EVs, but does not have the waste management infrastructure to process battery waste. Through a model analysis for India, we projected that the sale of...

Intensifying ecological crises, such as climate change, the melting Arctic, and uncontrolled destruction of habitat and biodiversity, are increasingly exposing the shortcomings of resource-intensive development models. One of the concepts helping policymakers steer a course change is sustainable consumption production and consumption (SCP). A...

Starting in August 2019, the SWITCH Asia SCP Facility has provided technical support to Vietnam’s Ministry of Industry and Trade (MoIT) for development of the National Action Plan on Sustainable Consumption and Production (2021.2030) (NAP on SCP). The SCP Facility established a team of international and national experts to conduct an assessment on...

While the initial pieces of evidence indicate that COVID-19 induced economic slowdown and lockdown present short-term benefits to air quality and the environment, these also pose a double-edged challenge in the long-term. On one side, the slowing down of the economy can have an adverse impact on countries’ ongoing efforts towards climate mitigation...

第五次環境基本計画は，環境・経済・社会問題が相互に連関しているという認識のもと，それを解決するために，持続可能な開発目標（SDGs）およびパリ協定の採択という時代の転換点を契機とする新たな文明社会へのパラダイムシフトを要請している．本稿は，このようなパラダイムシフトにつながる政策として，第五次環境基本計画の重点戦略を支える「地球温暖化対策計画」（2016年5 月13 日閣議決定）の長期目標である2050 年までに80％の温室効果ガス（GHG）の排出削減を達成することを目的とした本格的な炭素税導入を核としたグリーン税制改革を取り上げ，グリーン税制改革によって豊かな暮らしを維持すると同時に大幅なGHG 排出削減を達成することが可能であることを示した．

This report looks at national policies and initiatives related to sustainable consumption and production in Asia, without pretending to offer an exhaustive inventory of such policies and initiatives. It was developed based on literature review, integrating information collected through key regional projects such as SWITCH Asia and SwitchMed. The...

Soil moisture (SM) plays a key role in many environmental processes and has a high spatial and temporal variability. Collecting sample SM data through field surveys (e.g. for validation of remote sensing-derived products) can be very expensive and time consuming if a study area is large, and producing accurate SM maps from the sample point data is...

We use crowdsourced GIS data from OpenStreetMap to help automate the mapping of land cover in Landsat satellite imagery. The OpenStreetMap data had limited area coverage, but was useful for building a model which could classify land cover in the other areas.
