The UN has briefed Member States on progress under work package 27 of the UN80 reform initiative Action Plan, which seeks to “undertake a thorough assessment of current arrangements and make proposals on possible structural changes and programme realignments on environmental issues.” The briefing highlighted key findings from assessments of current arrangements on science, governance, coordination, and implementation.

In his report on ‘UN80 Initiative Workstream 3: Changing Structures and Realigning Programmes,’ the UN Secretary-General noted that while “[e]nvironmental issues are growing in importance, … environmental responsibilities are dispersed across UN entities.”

Responding to this challenge, work package 27 aims to:

• Highlight the importance of a healthy environment to the three pillars of the UN Charter;
• Strengthen environmental governance to accelerate synergistic action and collaboration across UN entities;
• Strengthen coordination and collaboration of UN work on environment to enhance policy coherence in support of implementation of environmental commitments; and
• Strengthen UN system support to multilateral environmental agreement (MEA) implementation and environmental action by Member States.

The briefing emphasized science as a vital component of the UN system’s ability to address environmental challenges and noted its central role in realizing the right to a healthy environment. Yet, the assessment found duplication, inefficiencies, and missed opportunities for collaboration in how environmental science is produced and used. Other challenges include translating global scientific outputs into actionable insights at the country level and engaging across entities in the development of environmental benchmarks. The assessment concluded that while the UN system does not require major structural reforms in environmental science, better connecting, aligning, and leveraging existing capacities would be advantageous.

The briefing described the complex MEA governance landscape, marked by overlap as well as gaps across processes, support structures, mandates, memberships and policy agendas. It noted the significant burden imposed on Member States by reporting demands across multiple MEAs. While successful processes have enabled greater administrative and programmatic synergies across MEAs, the briefing noted that efficiencies and co-benefits could be strengthened in how the UN system supports national-level implementation. In particular, the UN Environment Assembly’s (UNEA) system-wide convening potential could be better utilized. The briefing pointed to clear opportunities to advance greater coherence and strengthen global environmental governance through a system-wide outlook.

On coordination, the briefing outlined UN system engagement on the environment, which shows high concentration on climate and biodiversity actions, with pollution actions receiving comparatively less attention. It highlighted the importance of strengthening connections between science and policy to translate global priorities into coordinated support. It further noted that while the financing architecture can drive coordination, fragmented funding often undermines system collaboration.

Regarding implementation, the briefing emphasized that while Member States are required to navigate increasingly complex, often connected, MEA commitments, access to information and technical support to identify and implement crosscutting solutions is often insufficient. Among the challenges, it highlighted limited support from real economy actors, the impact of duplication and transaction costs on implementation delivery, and the lack of aligned and coordinated UN support for national implementation.

The briefing underscored that the financing needs associated with implementing MEA commitments require private sector investment, “with public finance playing a catalytic role in reducing risk and enabling new markets,” yet engagement between MEAs and the private sector remains limited and fragmented.

In conclusion, the UN invited Member States to provide guidance on:

• How to elevate UNEA in the multilateral system and how to strengthen science-policy-action through the Assembly;
• Pathways for MEAs to address the issues of fragmentation and dispersion of environmental governance;
• Strengthening environmental coordination and collaboration for science-policy-action in the UN and beyond;
• Highlighting the positive multiplier effect of a healthy environment to development, peace, and human rights; and
• Potential structural changes or programmatic alignments.

Work package 27 of the UN80 Action Plan is led by UN Environment Programme (UNEP) Executive Director Inger Andersen and UNFCCC Executive Secretary Simon Stiell. Participants include 20 entities from UN Secretariat, specialized agencies, funds and programmes, regional economic commissions, MEAs, and coordinating mechanisms. The briefing took place on 23 April 2026. [Environment in UN80 Work Package 27] [UNEP Briefing] [CITES Notification to Parties]
