Haselhorst Associates and H&Z are growing even closer. In August 2026, Haselhorst Associates GmbH was legally merged into H&Z Unternehmensberatung GmbH. The merger does not affect ongoing projects and clients. The people behind our projects and our long-standing client relationships, as well as our expertise, remain unchanged.
However, we are expanding the expertise available to you with our new business unit H&Z Performance & Restructuring.
Which came first: smart cities or sustainability? In the context of the debate surrounding urban transformation, the pendulum seems to be swinging increasingly toward smart cities—a mistake, as our colleague Dr. Lucia Wright explains in an interview with Der neue Kämmerer.

Tallinn was recently voted the “European Green Capital”. Estonia’s capital has thus impressively demonstrated how far a city can go in bringing down its carbon emissions, given the necessary will and courage to act.
