In June 2024, OPLN launched the INC-5 Sprint to develop science-backed safety and sustainability criteria across four key pillars: Safety, Environment, Sociocultural, and Economic. These criteria aim to guide the effective evaluation, monitoring and transparency frameworks of plastic alternatives and non-plastic substitutes. Through multi-stakeholder advisory and consultations, OPLN developed the INC-5 Negotiators’ Brief to Harmonized Safety and Sustainability Criteria (HSC). This document calls for INC-5 negotiators to mandate the development of HSC within the UN Global Plastics Treaty to end plastic pollution. HSC are a set of comprehensive, science-based principles for assessing the safety and sustainability of plastic alternatives and non-plastic substitutes, including associated chemicals of concern, and their supportive systems, services, and technologies, collectively referred to as ‘products and systems’. The HSC were presented at INC-5 side events in Busan, South Korea and have informed and aligned with the draft treaty text moving into INC 5.2.

In May 2024, the Ocean Plastics Leadership Network (OPLN) hosted a four-day, multi-stakeholder, immersive tour of two of North America‘s best-performing systems for packaging recovery, powered by extended producer responsibility (EPR), deposit return system (DRS), reuse and refill. This four-day expedition, from May 14th to 17th, brought together 31 participants representing major organizations across the packaging value chain (from material producers, packaging converters, top brands, major retailers, waste management, recyclers, and leading environmental organizations).

OPLN‘s technical expeditions foster collaboration, powered by experiential learning, to advance policy harmonization on EPR & DRS across the US among Fortune 500 sustainability leaders, policymakers, leading NGOs, and government officials.

Between September 10 - 13, 2024, the Ocean Plastics Leadership Network (OPLN) hosted a remarkable technical exhibition exploring the deposit return systems, extended producer responsibility policies and practices, and re-use and refill systems in Portland, Maine and Montréal, Québec. We brought together 40 participants - from policymakers to major organizations across the beverage container and packaging material value chains - to foster collaboration, experiential learning, and policy development on circular policies.

OPLN is grateful to its partners and participants for their contributions to this valuable, irreplaceable forum for learning and dialogue. Relive the highlights and insights from this impactful expedition, advancing our journey towards a sustainable future!

This comprehensive programme report captures the insightful discussions from the recent UK National Treaty Dialogues on Plastic Pollution. From 3-16 September 2024, stakeholders from across the UK plastics value chain – including NGOs, academia, upstream, downstream and midstream sectors - convened virtually for the fifth session of the UK Plastic Treaty Dialogues. Organised by OPLN in partnership with the UK Government's Department for Environment, Food and Rural Affairs (Defra), the dialogues were composed of both sectoral and plenary discussions, serving as a platform to share insights and views on the treaty.

These dialogues were held with two primary objectives in mind: to reflect on the intergovernmental negotiation process and to inform the UK's contributions at the fifth session of the Intergovernmental Negotiating Committee on plastic pollution (INC-5) in Busan, South Korea. INC-5 is scheduled to be the final session to develop a legally binding instrument on plastic pollution and will take place between 25 November – 1 December 2024.

This report records the views expressed by stakeholders during the sessions as valuable input to support the development of UK positions but should not be taken as UK Government policy.

We are delighted to announce the release of the Reuse & Refill Playbook for Retailers, a groundbreaking initiative developed through collaborative efforts within the Consumer Packaged Goods (CPG) Working Group of the Reuse and Refill Action Forum, facilitated by OPLN in partnership with Upstream and the Meridian Institute. This playbook marks a significant stride towards advancing sustainable practices within the retail industry by offering comprehensive guidance on priority product categories, including snacks, beverages, pet food, personal care, and household cleaners, that are well positioned to lead the transition towards reuse and refill solutions in major retailers. It addresses key thematic areas such as packaging, logistics, consumer participation, and cross-value chain collaboration modalities. With the participation of over 60 organizations, encompassing top CPG brands, major retailers, packaging producers, government representatives, and more, our collective aim was clear: to pave the way for a future where reuse and refill systems become the norm across all product categories.
