Bloomberg CityLab
Every year, Bloomberg Philanthropies hosts CityLab, the preeminent global cities summit which gathers the most influential mayors and voices from hundreds of cities worldwide. Bloomberg CityLab was founded on the principle that the most important innovation is happening at the local level and that global impact can be achieved when cities share solutions.
Summits have made international headlines, and generated tangible takeaways for attendees. Bloomberg CityLab 2026 convened mayors and leading policymakers, innovators, and creatives in Madrid, Spain from April 27 – 29. Past CityLab conferences have been hosted in New York, Los Angeles, London, Miami, Paris, Detroit, Washington, D.C., Amsterdam, and Mexico City.
