About UN80

The UN80 initiative was launched by UN Secretary-General António Guterres in March 2025, marking the UN 80th anniversary.

At the heart of UN80 are three major workstreams. The first is focused on improving internal efficiency and effectiveness, cutting red tape, and optimizing the UN’s global footprint by relocating some functions to lower-cost duty stations. The second workstream is a mandate implementation review, which involves examining nearly 4,000 mandate documents underpinning the UN Secretariat’s work. A mandate refers to a task or responsibility assigned to the organisation by the Member States, usually through resolutions adopted by UN organs such as the General Assembly or the Security Council. The third stream explores whether structural changes and programme realignment are needed across the UN System.

Through resolution 79/318 , the General Assembly welcomed the Secretary-General’s efforts and expressed its anticipation of receiving detailed proposals. Subsequently, in decision 79/571, the Assembly established an informal ad hoc working group, open to all Member States and observers, to consider the Secretary-General’s proposals under Workstream 2 of the UN80 Initiative. The group was tasked with identifying guiding principles and follow-up actions to strengthen the creation, delivery, and review of mandates.

In September, UN Secretary-General António Guterres shared a progress report on structural reforms and programme realignments under Workstream 3 the UN80 Initiative. The report, Shifting Paradigms: United to Deliver, developed through system-wide consultations, outlines possible adjustments in how the UN is structured, how its entities collaborate, and how it operates. It is the third major output of the Initiative, following earlier reports on efficiency measures and on mandate implementation review. Issued just before the General Assembly’s High-Level Week, the document was intended to inform Member States’ deliberations. Art. 47 of this report refers to environmental issues:

“Environmental issues are growing in importance, and environmental responsibilities are dispersed across UN entities. We will undertake a thorough assessment of current arrangements and make proposals on possible structural changes and programme realignments on environmental issues.”

For the UN system, the initiative is coordinated by the UN80 Task Force, chaired by Guy Ryder, Under-Secretary-General for Policy, ensuring coherence and strategic direction across the organization.

UN80 Action Plan and the Environment

The UN Secretary-General has shared the finalized Action Plan for UN80 with UN Member States in November 2025. Bringing together proposals from across the UN80 Initiative’s three workstreams, the plan creates a single, coordinated framework to strengthen alignment and accountability “under one roof”. A new Steering Committee was set to provide strategic guidance, and a reconfigured Task Force will drive implementation, ensuring progress is consistent, collaborative, and results-driven.

A Dashboard, developed as an annexe to the UN80 Initiative Action Plan, presents the detailed work packages across the three UN80 Initiative workstreams in a single reference. The Dashboard also lists designated leads for each work package, along with their individual action items.

Work package 27 of the Action Plan, led by Inger Anderson, UNEP Executive Director, and Simon Stiell, Executive Secretary of the UN Framework Convention on Climate Change, is to “undertake a thorough assessment of current arrangements and make proposals on possible structural changes and programme realignments on environmental issues”.

Statements and reports on coordination on environmental matters referring to UN80 include:

• In the second part of her report to the 7th session of the UN Environment Assembly (UNEA-7) “Priorities for advancing sustainable solutions for a resilient planet“, released in September, UNEP Executive Director Inger Andersen refers to the discussions ongoing under the UN80 Initiative reform banner, suggesting for example that Member States consider ways to enhance synergies among multilateral environmental agreements. She pointed to the example of the joint secretariat for the Basel, Rotterdam and Stockholm conventions, which continue to operate as separate conventions while holding their conferences of the parties in parallel, and being managed by that single secretariat. → Read the report
• In a statement delivered in October at the Committee of Permanent Representatives Subcommittee, UNEP Executive Director, Inger Andersen, stressed that the upcoming UN Environment Assembly, to be held in Nairobi in December 2025, will convene amid ongoing UN80 reform, offering Member States the opportunity to shape the future of environmental action within a reformed system. The Executive Director mentioned that UNEP has actively contributed to this process under the Secretary‑General’s leadership. She emphasized the environment as a cross‑pillar of the UN, underlining its role in development, peace, security, and human rights. Highlighting the UN80 workstreams — efficiencies, mandate review, and structural realignments — she encouraged Member States to strengthen UNEP’s coordination functions, broaden the Environmental Management Group’s scope, and improve efficiencies in servicing conventions to keep environmental governance central to the UN80 reform. → Read the statement
• A draft resolution to UNEA-7 proposed by Mexico on strengthening UNEP’s Nairobi headquarters also references the UN80 Initiative, encouraging exploration of a Joint Knowledge Hub on the environment, as envisioned by the UN Secretary-General.
• The Stakeholder Forum for a Sustainable Future (SF) released on 24 September the report “UN80: Reform of the Multilateral Environmental Agreements – Around the Triple Planetary Crisis of Pollution, Biodiversity, and Climate Change“, focusing on the opportunity for “clustering” the UN treaties on pollution. It also examines how the relevant science bodies for these three clusters can cooperate more effectively and proposes that the Global Environment Ministers Forum be re-established to meet in the year the UN Environment Assembly does not convene.
