Social sustainability takes into account people’s needs. In Freiburg, the urban planning process involves local people in the planning process both at the local and city level. Groups of children give feedback and offer their opinion on all new city developments, such as new building construction. Other features include local people being able to invest in renewable energy resources and, in addition to financial returns, receive free football season passes. Also, financial rewards are given to people who compost green waste and use textile nappies.
