The move marks a major milestone under the UN80 Initiative, a system-wide reform effort to make the UN more effective, coherent and better equipped to deliver results in a changing world.
Speaking in the General Assembly Hall, Secretary-General António Guterres welcomed the adoption, calling it a “historic resolution” and “a major step”.
“The resolution adopted today reflects a shared understanding of the full mandate lifecycle – and a shared commitment to strengthen each step of it,” he told Member States. “Today’s resolution helps translate the ambition of the UN80 Initiative into concrete, practical action.”
Why mandates matter
By creating mandates, Member States instruct and guide the whole UN system on how to address global challenges: from supporting peace and security and delivering humanitarian aid, to advancing development and protecting human rights.
Over time, however, the large number of mandates has created practical challenges.
Since 1946, more than 40,000 resolutions, decisions and presidential statements have been adopted across key UN bodies – a landscape that is increasingly difficult to navigate.
This has contributed to duplication and overlap, proliferating reports and meetings, and limited visibility and review mechanisms across the system.
This can place a heavy burden on both Member States and the United Nations system, while making it harder to ensure effective and efficient mandate implementation.
The first of the UN’s mandates were agreed upon by Member States during the term of the first UN Secretary-General, Trygve Lie (right) from February 1946.
‘A more structured approach’
The resolution introduces, for the first time, a more structured approach across the full mandate lifecycle – from design to implementation and review.
In practice, this means:
· Clearer and more focused mandates, supported by better information for decision-making from the outset;
· Stronger and more coordinated implementation, with improved use of data, more user-oriented reporting and more effective use of resources;
· More systematic review of results, helping ensure mandates remain relevant and deliver impact, reinforcing a culture of continuous improvement, grounded in evidence, accountability and results.
· Increased transparency through improved digital tools, including through an expanded UN Mandate Registry, giving Member States more consolidated and comparable information on mandates, resources and results.
Why this matters
The resolution is intended to make it easier for Member States to navigate an increasingly complex mandate landscape, while helping the United Nations reduce duplication, fragmentation and inefficiency.
By strengthening how mandates are designed, delivered and reviewed, it aims to improve how the UN system translates decisions into results.
What happens next
The resolution builds on the work of the General Assembly’s Informal Ad Hoc Working Group on the Mandate Implementation Review, co-chaired by Jamaica and New Zealand.
The Working Group was established by the General Assembly to consider the proposals contained in the Secretary-General’s July 2025 report on the Mandate Implementation Review, prepared under Workstream 2 of the UN80 Initiative.
That report examined how mandates are created, implemented and reviewed across the United Nations system, and set out proposals to strengthen each stage of the mandate lifecycle.
The resolution decides to deliver through a formal Ad Hoc Working Group on Mandate Implementation Review, open to all Member States and observers. The tasks include, for example, developing better practical templates, stronger review clauses and further review of existing mandates.
“This is a major step. But it is only the beginning. We will work as a single, coherent Organization – guided by the Working Group – to improve how mandates are supported and implemented”, Mr. Guterres said while reaffirming that this remains a Member State-led process.
Echoing this sentiment, the President of the General Assembly, Annalena Baerbock, said that the adoption marked an important step in a much broader reform effort and invited Member States to continue engaging in the next phase of the work.
“Today we took an important step to make the UN more agile, more efficient, more effective, and fit for the future, so it can better deliver for the people we serve”, she said.

The UN80 Initiative
The resolution is the latest milestone of the UN80 Initiative. Launched by the Secretary General a year ago, the Initiative is designed to impact the UN from top to bottom, so that every mandate, dollar and decision delivers maximum value for people and planet.
Next Monday, the General Assembly will hold an informal meeting to receive the latest update on the UN80 Initiative Action Plan, including proposals under workstream 3 which outlines possible structural and programmatic realignments to better align the UN System. It will be live on UNWebTV.
