The effectiveness of an international plastics agreement depends not only on its final wording, but also on who can contribute evidence and lived experience while that wording is developed.

Access to the process

During the second session of negotiations for a global plastics treaty in Paris, concerns emerged about restrictions on participation. Although the international mandate encouraged broad and effective involvement, logistical limits meant that some registered non-governmental organisations could nominate only one person to attend.

Such restrictions can affect groups whose work and daily lives are closely connected to plastic pollution, including waste workers, younger participants and Indigenous representatives. They can also reduce opportunities for independent researchers to provide specialist evidence. Academics without direct accreditation may depend on civil-society organisations for registration, making limited places especially consequential.

The role of independent evidence

The treaty process has been moving faster than the development of a standing, independent assessment structure comparable with those used for climate or biodiversity. That makes transparent access to diverse scientific expertise particularly important. Rapid reports can inform discussion, but they cannot necessarily provide the same depth of review, disciplinary range or consensus-building as longer assessment processes.

Debate around a report prepared to support the negotiations illustrated this issue. Critics questioned its treatment of production limits, its distinction between necessary and unnecessary production, and the extent to which responsibility was framed around demand and consumer behaviour. Questions were also raised about assumptions that circular material flows would, by themselves, reduce the risks associated with chemicals in plastics.

What the critique emphasised

  • Meaningful participation requires more than formal observer status; people need practical access to negotiating spaces.
  • Communities affected by plastic pollution should be able to contribute directly to policy discussions.
  • Independent scientists need transparent routes for presenting and testing evidence.
  • Production, chemical safety, consumption, product design and waste systems should be examined together.
  • Fast policy assessments should state their scope, evidence limits and assumptions clearly.

Why representation matters

Plastic pollution crosses material, health, labour, trade and environmental systems. A negotiating process that includes relevant communities and independent disciplines is better placed to identify trade-offs, challenge weak assumptions and distinguish technically credible options from simple claims.

The central argument was procedural: transparency and meaningful scientific participation can strengthen the legitimacy and usefulness of the treaty. Attendance rules may appear administrative, but they shape which evidence reaches decision-makers and whose experience is reflected in negotiations.
