Policy Options for Halting New Flows of Marine Plastic Litter by 2050 under the G20 Osaka Blue Ocean Vision (Japanese Translation)
Original title: G20大阪ブルー・オーシャン・ビジョンの下で2050年までに海洋プラスチックごみの新たな流入を止める政策オプション（日本語翻訳版）
AI summary Read the abstract
This policy analysis, commissioned by the G20 in support of the Osaka Blue Ocean Vision, evaluates upstream and downstream policy interventions needed to eliminate new marine plastic pollution by 2050, drawing on scenario modeling to outline the systemic changes required across the plastic economy to achieve zero additional ocean plastic inputs.
国際資源パネル（IRP）「Policy Options to Eliminate Additional Marine Plastic Litter by 2050 under the G20 Osaka Blue Ocean Vision」の日本語翻訳版（暫定非公式訳）。本シンクピース（解説文書）は、G20からの委託により、大阪ブルー・オーシャン・ビジョンを実現するために可能な政策オプションの定性的検討を行ったものである。大阪ブルー・オーシャン・ビジョンは、G20諸国に対し、「包括的なライフサイクルアプローチを通じて、2050年までに海洋プラスチックごみによる追加的な汚染をゼロにする」ことを自主的にコミットさせ、それによって2050年までに海洋に流入するプラスチックの正味量をゼロにすることを確保しようとするものである。「Breaking the Plastic Wave」（The Pew Charitable Trusts and SYSTEMIQ 2020）で公開されたシナリオモデル分析を通じて海洋プラスチックごみの2050年に関する動向を示すとともに、現在のプラスチック政策の状況を概観し、大阪ブルー・オーシャン・ビジョンの実現に向けた上流ならびに下流での政策介入を検討している。一連の分析に基づき、大阪ブルー・オーシャン・ビジョンの実現と、プラスチック経済に求められる体系的な変化への移行に向けた政策メッセージをまとめている。

Marine plastic pollution and extended producer responsibility in the G20
AI summary Read the abstract
This systematic mapping of 100 academic and policy sources analyzed how extended producer responsibility (EPR) can reduce marine plastic litter in G20 countries, which are responsible for a significant portion of global plastic production and consumption. The review recommended strengthening legislative frameworks, incentivizing plastic return markets, improving lifecycle management of plastics, and coordinating EPR strategies from global conventions to local implementation in the context of ongoing UNEA Resolution 5/14 treaty negotiations.
Policy Scenarios for Eliminating Plastic Pollution by 2040
AI summary Read the abstract
This OECD report models the environmental and economic consequences of different international policy scenarios aimed at ending plastic pollution by 2040, finding that current policies are insufficient to alter plastic flow trends. More ambitious circular economy policies could dramatically reduce plastic leakage to the environment, though economic trade-offs vary by approach.
