The Brussels Urban Summit (BUS) is around the corner. On 12-15 June 2023, this event will gather over 300 cities worldwide and more than 1000 politicians, experts and representatives of civil society to exchange ideas and envision a future of sustainable, affordable, and liveable cities. It will bring together three international city conferences: the 14th Metropolis World Congress, the Eurocities Annual Conference and the sixth OECD Champion Mayors Summit for Inclusive Growth Initiative. We know that for all our diversity, cities worldwide share common challenges. Offering a varied programme of plenary sessions, workshops, side events and site visits, BUS will be a forum for exchange and debate. The summit provides a unique opportunity to engage in a global strategic dialogue to help define our shared urban future. This unique gathering is an initiative of Brussels Capital Region, Eurocities, Metropolis and the OECD Champion mayors for Inclusive Growth Initiative.
