Japan Hosts Informal Talks to Advance Global Plastic Pollution Treaty

Informal Discussions Underway in Japan

Delegates from around 20 countries have convened in Japan for three days of informal, closed-door talks aimed at advancing efforts towards a global treaty on plastic pollution. The meetings, which commenced on Sunday, March 1, 2026, are being held among 'working-level officials' and are not expected to yield any official announcements. Japan is hosting these sessions in an effort to 'push for progress' and 'bridge differences' that have stalled formal negotiations on a landmark agreement to combat plastic waste.

Stalled Progress in Global Negotiations

The current informal talks follow a series of formal negotiation rounds by the Intergovernmental Negotiating Committee (INC), established by the UN Environment Assembly (UNEA) in March 2022 to develop a legally binding instrument on plastic pollution. Previous sessions, including the supposedly final talks in Busan, South Korea, in 2024 (INC-5.1) and a renewed effort in Geneva in August 2025 (INC-5.2), failed to reach a consensus. A key point of contention remains the scope of the treaty, with some nations advocating for ambitious measures such as curbing plastic production, while others, including major oil-producing states, prefer to focus primarily on waste management.

Japan's Role and Objectives

Japan has taken a proactive stance in these global efforts, having previously proposed the 'Osaka Blue Ocean Vision' at the 2019 G20 Osaka Summit, which aims to reduce additional marine plastic litter to zero by 2050. The nation has also expressed an ambition to reduce additional plastic pollution to zero by 2040. By hosting these informal gatherings, Japan seeks to foster dialogue and help resolve fundamental differences before the next formal negotiation stages.

Diverse Participation and Persistent Challenges

The informal talks in Japan include representatives from a diverse group of nations, reflecting the global nature of the plastic pollution crisis. Countries expected to be present include:

• Major oil producers such as Saudi Arabia, Russia, and the United States
• Island states like Antigua and Barbuda, and Palau
• Large economies including China, India, and the European Union

These discussions are crucial as negotiators grapple with complex issues, including production limits, the regulation of chemicals in plastics, and financing mechanisms for the treaty. The election of Julio Cordano of Chile as chairman in early February underscores the ongoing commitment to finding a path forward, despite the 'little progress' made in recent months.
