Overview
- Barcelona’s Jaume Collboni and London’s Sadiq Khan met in Madrid at the Bloomberg CityLab forum and called for city centers that serve local residents.
- They agreed to begin a technical exchange in July so staff can share practical methods on street design, housing rules, and cutting emissions.
- The mayors compared flagship projects on La Rambla and Oxford Street as models to boost local life, small shops, and cultural spaces.
- Collboni restated Barcelona’s housing push with a cap on rent increases and a 2028 end to tourist-flat licenses that would return about 10,000 homes to long-term use.
- Khan, who leads the C40 climate network, said he wants to learn from Barcelona and urged cities to collaborate through networks that spread what works.
