世界プラスチック条約を支援するためのデータギャップの解消 報告においては、データの調和、サプライチェーンの指標、汚染ホットスポットの特定を考慮する必要がある。 Bridging data gaps to support the Global Plastics Treaty Reporting should consider data harmonization, supply chain metrics, and pollution hotspot identification

Abstract

In 2022, the Intergovernmental Negotiating Committee (INC) began developing an international legally binding instrument (ILBI) on ending plastic pollution. After five sessions, originally planned to culminate in INC-5.2 in August 2025, member states compromised extensively on contentious issues (1) but failed to achieve consensus. An additional session is scheduled for March 2027 to advance the instrument. Adoption of the treaty will mark only the initial phase of global efforts to combat plastic pollution. Robust data are essential at every stage of this journey to map out and implement actionable solutions: negotiating scientific data-based measures, conducting effectiveness evaluations, and establishing standardized global data systems with scientific and societal value. Yet the INC-5.2 chair’s text fails to prioritize binding data disclosure obligations. We provide national reporting recommendations for the ILBI, outlining data harmonization, metrics along the supply chain, and pollution hotspot identification to support treaty implementation and evaluation.
