Every September, world leaders, diplomats, and advocates gather for the United Nations General Assembly – one of the most important moments on the global diplomatic calendar.
Next week, UN Headquarters in New York will once again host critical debates and discussions on some of the world’s most pressing issues: from peace and security to climate action, sustainable development, and human rights.
The 80th session of the UN General Assembly (UNGA 80) opened on Tuesday, September 9, 2025. The high-level General Debate will run from September 23 to 27 and conclude on September 29, 2025. The SDG Moment will be held on September 22 to highlight inspiring action on the Sustainable Development Goals.
As the UN turns 80, this year’s General Assembly is said to be a reminder of how eight decades of global cooperation have improved lives around the world.
Since 1945, the United Nations has worked to prevent conflict, deliver humanitarian aid, defend human rights, promote development, and much more. From eradicating smallpox to delivering lifesaving aid in crises, the UN has helped people everywhere build safer, healthier, and more hopeful lives.
Ahead of this year’s Assembly, United Nations Secretary-General António Guterres stressed that people around the world are calling for answers and action.
“Our times demand more than posturing and promises. They demand that leaders make progress and follow through.”
Calling on leaders to “get serious and deliver,” the Secretary-General urged: “Let this be a week of solutions.”
