Planning and approval processes in Germany are very time-consuming, especially for large infrastructure projects in the transport sector. German politicians, in particular, are always keen to look to their neighbour Denmark, where these processes are often carried out in much shorter periods of time. One reason for the shorter processes is seen in the early involvement of the public in large projects. The public is involved at an early stage in the planning process and turned into "planners". This promotes the acceptance of a project so that resistance to it can be eliminated at an early stage. As a result, less time is required for the planning and approval processes. It is therefore not surprising that demands are being made to adapt Danish forms and formats of participation in Germany. "Learning from our Danish neighbour means accelerating processes in Germany," this is frequently the credo of German politics. Is that the case? The lecture deals with the question of whether an adaptation of Danish forms of participation in Germany is actually suitable for achieving the desired goal of increased public acceptance and acceleration of processes. Using the example of the Fehmarnbelt Fixed Link project, concrete forms of participation are presented.
