Model UN Background Guide

Committee: United Nations Environment Programme (UNEP)
Topic: Plastic Pollution Treaty
Conference Year: 2026

1. Topic Background

Plastic pollution has become one of the most pressing environmental challenges of the 21st century. Since the mass production of plastics began in the mid-20th century, global plastic consumption has skyrocketed, leading to widespread contamination of terrestrial and marine ecosystems. Plastic debris harms wildlife, disrupts ecosystems, and poses risks to human health through microplastics entering food chains. The issue gained international prominence with studies highlighting the Great Pacific Garbage Patch and microplastics found in remote regions such as the Arctic.

Historically, efforts to manage plastic pollution have been fragmented and largely national or regional in scope. The Basel Convention’s amendments on plastic waste and regional bans on single-use plastics represent some steps forward but have not addressed the global nature of the problem comprehensively. The complexity of plastic pollution—stemming from production, consumption, waste management, and recycling—requires coordinated global action.

The impetus for a global plastic pollution treaty has grown in recent years due to mounting scientific evidence, public pressure, and increasing recognition of plastics’ role in climate change (both as a fossil fuel derivative and through emissions from waste incineration). In 2022, the United Nations Environment Assembly (UNEA) adopted a resolution to begin negotiations toward an international legally binding instrument on plastic pollution, including its entire lifecycle. This treaty process is now underway, with the goal of finalizing an agreement by 2026.

The plastic pollution treaty is on the agenda of UNEP in 2026 because member states are at a critical juncture: they must decide on the scope, obligations, financing mechanisms, and enforcement measures of the treaty. The outcome will shape global governance of plastics for decades and influence related sectors such as waste management, trade, and sustainable development.

2. Key Actors

States

• European Union (EU) Member States: The EU has been a leader in plastic pollution policy, with the European Green Deal including targets to reduce single-use plastics and improve recycling. The EU pushes for ambitious, binding commitments in the treaty.
• United States: While historically more hesitant on binding environmental treaties, the US has recently increased engagement on plastic pollution, emphasizing innovation, circular economy approaches, and public-private partnerships.
• China: As the world’s largest plastic producer and consumer, China’s position is critical. It has implemented strict domestic policies on plastic waste imports and single-use plastics but balances environmental goals with industrial interests.
• Small Island Developing States (SIDS): Countries such as the Maldives and Seychelles are severely impacted by marine plastic pollution and advocate for strong global action, including financial and technical support.
• India and other large developing countries: These states emphasize the need for equitable responsibilities, technology transfer, and capacity building, often wary of overly stringent obligations that might hinder economic development.

International Organizations

• United Nations Environment Programme (UNEP): The primary UN body coordinating global environmental policy and the secretariat for the treaty negotiations.
• Basel Convention Secretariat: Plays a role in regulating plastic waste trade and will be a key partner in treaty implementation.
• World Trade Organization (WTO): Though not directly involved in environmental treaties, WTO rules intersect with trade restrictions on plastics, making its position relevant.
• Non-Governmental Organizations (NGOs): Groups such as the Plastic Pollution Coalition and WWF influence negotiations through advocacy, scientific research, and public mobilization.

3. Bloc Positions

1. The Ambitious Environmental Bloc (EU, SIDS, Nordic countries, Canada)

• Advocates for a comprehensive treaty covering the entire lifecycle of plastics—from production to disposal.
• Supports legally binding targets and timelines for reduction, bans on certain single-use plastics, and mandatory reporting.
• Emphasizes the need for financial mechanisms to support developing countries, including technology transfer and capacity building.
• Calls for strong compliance and enforcement provisions.

2. The Developing and Emerging Economies Bloc (India, Brazil, South Africa, Indonesia)

• Stresses the principle of common but differentiated responsibilities (CBDR).
• Supports flexible commitments that consider national circumstances and development priorities.
• Requests robust financial and technical assistance to improve waste management infrastructure.
• Prefers voluntary or incentive-based measures over strict bans or quotas on plastic production.

3. The Production and Trade-Dependent Bloc (China, Russia, Gulf States)

• Focuses on balancing environmental goals with economic growth and industrial interests.
• Opposes overly restrictive measures on plastic production that could impact jobs and trade.
• Advocates for innovation and circular economy approaches rather than outright bans.
• Seeks to avoid trade disruptions and emphasizes harmonization with WTO rules.

4. The United States and Like-Minded States (US, Japan, Australia)

• Supports ambitious outcomes but prioritizes market-based solutions and public-private partnerships.
• Emphasizes innovation, research, and development of alternatives to plastics.
• Prefers flexible, non-binding commitments with room for national discretion.
• Supports transparency and data sharing but cautious about compliance mechanisms.

4. Past UN Action

• UNEA Resolution 5/14 (2022): Mandated negotiations for a legally binding international treaty on plastic pollution covering the entire lifecycle of plastics.
• UNEP Global Environment Outlook (GEO-6, 2019): Highlighted the environmental and health impacts of plastic pollution and called for coordinated international action.
• Basel Convention Plastic Waste Amendments (2019): Strengthened controls on transboundary movements of plastic waste.
• General Assembly Resolution 73/333 (2019): Recognized marine plastic litter and microplastics as a global problem requiring international cooperation.
• UNEP’s Clean Seas Campaign (2017-2022): Mobilized governments and businesses to reduce plastic waste, creating momentum for treaty discussions.

5. Questions a Resolution Should Answer

1. What is the scope of the treaty—should it cover all types of plastics and their entire lifecycle, including production, use, and waste management?
2. How should responsibilities be allocated among developed and developing countries, considering principles like CBDR?
3. What binding targets or obligations should be established for reducing plastic production, use, and pollution?
4. How will the treaty address financing, technology transfer, and capacity building for developing countries?
5. What mechanisms will ensure compliance, monitoring, and enforcement of treaty provisions?
6. How will the treaty interact with existing international agreements and frameworks, such as the Basel Convention and WTO rules?
7. Should the treaty include provisions for innovation, research, and development of alternatives to conventional plastics?

6. Further Reading

• UN Documents: Official UNEP reports, UNEA resolutions, and treaty negotiation texts provide authoritative information on the legal and policy framework of the plastic pollution treaty. These documents offer insight into member states’ positions and procedural developments.
• Think-Tank Reports: Analyses from environmental policy institutes and international affairs think tanks (e.g., International Institute for Sustainable Development, Chatham House) offer critical assessments of treaty options, feasibility studies, and impact evaluations. They often explore economic, social, and technical dimensions of plastic pollution governance.
• News Outlets: Reputable global news sources such as Reuters, The Guardian, and Al Jazeera regularly cover developments in international environmental negotiations, public opinion trends, and case studies of plastic pollution impacts. These provide context on political dynamics and stakeholder perspectives.

This background guide aims to equip delegates with a comprehensive understanding of the plastic pollution treaty negotiations in UNEP 2026, highlighting the complexities and stakes involved in crafting a global solution to this pervasive environmental challenge.
