On the weekend of 20 and 21 August, citizens could visit the Federal Chancellery, the Federal Ministries and the Federal Press Office in Berlin during Open Day. As an AI lighthouse project funded by the BMUV, we were present at the Ministry of the Environment and introduced our project. In addition to interested citizens, Dr Christiane Rohleder, State Secretary of the BMUV, also stopped by our stand and informed herself about the Green Consumption Assistant (GCA). We were very pleased about the interest in the GCA and were able to get useful feedback on both days.
