Who would believe that the international champion of cities in transition is a small French commune? Yet it is Rob Hopkins, the founder of the Cities in Transition movement, who says so. What are we waiting for ? Tells how a small Alsatian town of 2200 inhabitants has embarked on the process of transition to the after-oil by deciding to reduce its ecological footprint. In 2009, the Alsatian village of Ungersheim launched a participatory democracy program, entitled 21 Actions for the 21st Century. All aspects of daily life are present: food, energy, transport, housing, money, work and school. Since 2005 120 000 euros have been saved in operating costs and direct emissions of greenhouse gases have been reduced by 600 tonnes per year. About 100 jobs were also created.
