From 2007 to 2010, severe flash floods occurred in different cities in the Emscher- and Lipperegion due to extreme rainfall events. In the public discussion that followed, the question of responsibility came up. Citizens formulated the demand that the public bodies, particularly the municipalities and water boards, had to guarantee a full protection against future flood events. In further developing this demand, it quickly became clear that this would not be possible without paying a high price. Questions arose like: How high should the dikes be, and how big should the waste water sewers be dimensioned to protect people against any extreme event? How much energy and money would that cost? This would speak against all efforts regarding climate protection and reducing greenhouse gas emissions. A communication strategy was thus necessary to change citizen perspectives and develop support for a reasonable solution. The goals was to convince the population that there is no solution by public authorities which can offer 100% protection against the impacts of climate change, and that there will always remain a degree of personal responsibility. This was the starting point when people began to ask the question: What can I do?
