Five’s a crowd: divergence and delay at the first half of the fifth global plastics treaty negotiation (INC-5.1)
AI summary Read the abstract
Participant observation and document analysis of the UN INC-5.1 global plastics treaty negotiations in Busan (2024) revealed that fundamental disagreements between waste-management-focused nations and those advocating full lifecycle production limits prevented consensus, extending negotiations beyond 2026. The impasse underscores how divergent national interests continue to stall binding international action on plastic pollution at its source.
Abstract The United Nations (UN) Intergovernmental Negotiating Committee (INC) convened its fifth session of negotiations (INC-5.1) on a new international legally binding instrument to end plastic pollution from November 25–December 2, 2024, in Busan, South Korea. Initially anticipated to be the final session of negotiations, INC-5.1 concluded without reaching a consensus, highlighting divides among negotiating state parties. A central point of contention remained the divergent priorities of the group of like-minded countries, which advocate for a treaty focused primarily on waste management and the High Ambition Coalition, which calls for a comprehensive lifecycle approach addressing the production, use, and disposal of plastics. This paper examines the barriers and textual changes that defined INC-5.1, drawing on close participant observation and document analysis. Despite progress on financial mechanisms and monitoring frameworks, core obligations, such as limits on production and reduction targets, remain unresolved. Procedural disagreements also hampered the negotiations, with debates over the inclusion of detailed text proposals in the draft treaty further delaying consensus. Looking ahead, negotiations will now extend past 2026, with additional sessions being prepared to reconcile the competing visions for the treaty. This paper highlights the persistent challenges facing the negotiations and considers the implications of the extended timeline on the prospects for an effective global plastics agreement.

Deadlock at INC-5.2: Understanding the blocked progress of the Global Plastics Treaty negotiations
AI summary Read the abstract
The Global Plastics Treaty negotiations at INC-5.2 in 2025 collapsed due to a fundamental split between nations favoring upstream plastic production caps and oil-producing states limiting discussion to downstream waste management. This governance failure has profound implications for microplastic pollution, as without production limits, plastic fragmentation into the environment will continue accelerating.

AI summary Read the abstract
Following the INC-5 global plastics treaty negotiations in Busan, this commentary assesses current plastic production, recycling gaps (only 9% recycled globally), and the limitations of biodegradable alternatives. The authors call for continued international consensus-building alongside government regulation, industry responsibility, and individual behavior change to achieve sustainable plastic management.
Competing axes of power in the global plastics treaty: Understanding the politics of progress and setbacks in negotiating a high-ambition agreement
AI summary Read the abstract
This analysis examined the December 2024 UN plastics treaty negotiations in Busan, South Korea, where a majority of states supported high-ambition legally binding measures on hazardous plastics and chemical regulation, but petrostates and industry interests stalled progress. The paper identifies intersecting axes of pro-plastics power and argues that strengthening the high-ambition coalition and enhancing transparency are critical to achieving a robust global plastics treaty.
