The study submitted to the Ministry of Ecology and Sustainable Development in 2012, proposes a sectoral reading in terms of ecological transition. The work carried out by several institutions, including the Institute, has shown that the world of brand agents and car repairers has been able to demonstrate a permanent capacity to adapt since the beginning of its history (vehicle technology, regulations, appearance of new competitors, etc.) by relying on informal networks and/or by adding new activities. The professional logic observed and the capacity to adapt make it possible to hypothesise their capacity to move towards an ecological economy.
