From Launch to Legacy: Charting the Path of the Intergovernmental Science-Policy Panel on Chemicals, Waste, and Pollution

The establishment of the Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution (ISP-CWP) marks the first creation of a dedicated intergovernmental science-policy body addressing the sound management of chemicals and waste and the prevention of pollution. Emerging within a governance landscape shaped by a variety of longstanding international frameworks, the Panel seeks to strengthen the interface between scientific knowledge and decision-making in a domain characterized by diverse institutional actors, uneven capacities, and economic implications. This perspective analyzes the institutional conditions that will determine whether the ISP-CWP can translate its formal mandate into effective governance. We examine how its mandate, governance architecture, and core functions─including horizon scanning, solution-oriented assessments, knowledge inclusivity, and integrated capacity-building─may shape the Panel's credibility, legitimacy, and policy relevance in practice. While the Panel's design reflects lessons learned from earlier science-policy bodies, it also embeds structural tensions: between scientific independence and political oversight, timeliness and methodological rigor, inclusivity and operational feasibility. The ISP-CWP's long-term influence will depend less on its formal mandate than on how effectively it manages these trade-offs in practice. As such, the Panel represents a live experiment for the evolution of science-policy interfaces in politically sensitive and economically complex environmental domains.
