2025 Urban 20 Mayoral Summit
​12-14 September 2025 | Sandton, City of Johannesburg, South Africa

The City of Johannesburg and City of Tshwane are honoured to co-chair the 2025 Urban 20 (U20) cycle - a global platform that convenes locally elected leaders and officials from G20 cities to facilitate meaningful engagement between local governments and the G20.

As South Africa assumes the G20 Presidency in 2025, the U20 provides a critical opportunity to elevate the voice of cities in shaping global priorities.


The City of Johannesburg, affectionately known as Jozi, Joburg, Egoli, or the City of Gold, is poised to host the prestigious 2025 U20 Mayoral Summit from Friday, 12 to Sunday, 14 September 2025. This important gathering will convene mayors, city leaders, and policymakers from across the globe in a collaborative pursuit of innovative solutions and best practices.


Under the compelling theme, Cities leading the way in reimagining global change, the Summit's meticulously curated programme will delve into critical urban priorities:
  • Economic Opportunities and Finance
  • Climate Action and Urban Resilience
  • Social Inclusion and Equity
  • Digital Transformation

Hosted in Sandton, Johannesburg’s vibrant economic powerhouse and a nexus for finance, ICT, creative arts, and urban development, this dialogue is set to forge a sustainable legacy for urban communities worldwide.

We eagerly anticipate welcoming delegates to our dynamic City of Gold.


A new era 

for African urban leadership.


The Cities of Johannesburg and Tshwane are two of South Africa’s most dynamic and forward-thinking metropolises, have been appointed as the Co-Chairs of the Urban 20 (U20) for the 2025 cycle, following the handover from Rio de Janeiro and São Paulo in November 2024.

This historic appointment marks a significant milestone not only for South Africa but for the entire African continent. As Co-Chairs, Tshwane and Johannesburg will lead a global coalition of cities in addressing pressing urban challenges, fostering sustainable development, and amplifying the voice of African cities on the world stage.   

Under the theme Cities Leading the Way in Reimagining Global Change, Tshwane and Johannesburg will champion innovative, inclusive, and sustainable solutions to redefine how cities respond to global challenges. This theme reflects their commitment to driving transformative change, not only within their own borders but across the globe, by leveraging the power of urban innovation and collaboration.
