本書は、2024年2月UNEA6にて発表された、世界資源アウトルック（GRO）2024の内容をコンパクトにまとめた政策決定者向け要約（SPM：Summary for Policymakers）の日本語版。7つの地域、4つの所得国グループに及ぶ180カ国について、利用可能な最善のデータ、モデリングおよび評価を動員し、我々の資源利用の動向、影響、分配効果に関する分析をまとめるとともに、負の傾向を逆転させ、人類を持続可能な軌道へ乗せる可能性についても考察している。 資源利用量の増加が３つの地球危機（気候変動・生物多様性の喪失・汚染）の主な要因となっている。我々の経済活動のための物質資源の採取・加工は、過去50年間で3倍に増加、現在、温室効果ガス排出量の55％以上、粒子状物質（PM...

The year 2023 marked a concerning milestone in climate history with the global average temperature being 1.45 ± 0.12°C above the pre-industrial average. The Global Stocktake at COP28 showed that the projected temperature rise is expected to be between 2.1 - 2.8°C even if nationally determined contributions (NDCs) of all countries are fully achieved...

The scientific community generally recommends integrated approaches but has little clear guidance on concrete implementation. This paper reaches two main conclusions. First, environmental...

The process to define the sustainable development goals (SDGs), which took place between 2012 and 2015, was based on broad stakeholder engagement. As such, it was a unique communicative effort to integrate diverse voices into the process and its outcomes. After nearly a decade, the year 2023 marks the midpoint in the implementation of the SDGs...
