The conference in Schloss Herrenhausen can accommodate a total of 300 participants. We reserve the right to contact you if registrations from a municipality or organisation exceed capacities, as the number of participants will then have to be reduced. 

For capacity reasons, we had to close the registration.

The Climate Neighbourhoods event in the Schloss Herrenhausen Orangerie offers a dynamic supplementary programme to ICCA2015 which is open to the public.
