Berlin in Metropolis

  • Ideas, suggestions, and perspectives from other major cities inform Berlin’s own approach to dealing with current challenges in, for instance, the area of affordable housing or sustainable transportation policy.
  • A strong voice when dealing with international organizations to which Berlin would otherwise have only limited access.
  • Berlin’s own innovative ideas and problem-solving skills are given greater visibility.
