The report is about the implementation of Task 4.4.3. City Day: Discovering my City - Healthy and Clean Tips in Bristol. The topic of the activity is smart, non-motorised mobility of citizens in Europe to show the walking and cycling routes of the city. The activity invited older citizens from the cities to promote their own smart mobility. Short films were prepared about the smart mobility tips which show the health, environmental and social benefit of the smart moves in the city. The REC provided guidelines and some templates, which described the general concept of organising the ClairCity Film Campaigns, culminating in the City Days. Based on this information the Bristol project team adapted the methodology to their specific circumstances and implement the campaign for filming and the City Day event.
