The global plastic pollution treaty process has entered a decisive planning phase, as the Chair of the Intergovernmental Negotiating Committee (INC) outlined a detailed 2026 roadmap towards INC-5.4, expected in late 2026 or early 2027. The roadmap establishes a structured series of meetings to support negotiations on a legally binding agreement, with significant implications for stakeholders across the chemicals and manufacturing value chain.
The roadmap introduces regular virtual meetings of Heads of Delegation every four to six weeks, alongside a key in-person meeting in Nairobi from 30 June to 3 July 2026. These sessions aim to ensure transparency, inclusivity and predictability throughout the negotiation process. An additional in-person meeting in October 2026 remains under consideration, subject to available financial resources. The Chair also indicated that INC-5.4 would likely require a ten-day session to enable meaningful progress. A critical challenge remains the absence of a single draft treaty text. To address this, an informal reference document is expected to be developed following the June meeting. This document will reflect progress to date and clearly present areas of agreement and divergence, without introducing new proposals.
While the letter does not define specific regulatory measures, it confirms continued momentum towards a legally binding global agreement on plastic pollution. For industry stakeholders, this signals increasing regulatory certainty in terms of direction, but continued uncertainty regarding the exact scope of obligations. Professionals across the chemicals value chain should note that future measures may address different stages of the plastics lifecycle. However, the current roadmap focuses primarily on process, engagement and negotiation structure rather than policy detail. As a result, companies should closely monitor developments, particularly the forthcoming reference document, which is expected to provide clearer insight into the evolving areas of consensus and divergence.
The roadmap places strong emphasis on inclusive participation. Informal discussions among Member States are encouraged, particularly between those with differing positions. Observers, including industry representatives and civil society, are also recognised as essential contributors to the process. Flexible working methods such as informal consultations and targeted discussions will support progress. The Chair also plans regular stocktaking moments to assess negotiation advances and guide next steps.
Stakeholders should prioritise tracking upcoming INC meetings and engaging through relevant industry groups and consultation channels. Early awareness of negotiation dynamics will be critical as discussions move closer to a consolidated treaty framework.
