The environment we create affects us as individuals and as a society. The buildings are its cornerstone. Let us not get contented with a few exceptional buildings that Council members can take pride in, that we leave here for future generations but let us make sustainable building an absolute standard. We have knowledge, we have technology, we have experience, let's use it to achieve the goal. The steps that lead to this are formulated by this declaration. We are well advanced on this journey, let's move on.
