This research deals with the relation between extraction sites and sustainable development in Brittany, and aims at analysing the modalities of governance within this industrial activity. Since 1993, all extraction sites have, by law, an obligation to consider environmental issues and local community demands in their projects, whenever a site is to be opened or extended: 1) The opinion of the local resident is highly important because they desire to create a territory that suits the needs of their local community and that preserves a way of life strongly associated with rural areas. Their increasing participation in local councils and meetings is a testimony for their long lasting involvement. 2) On the other hand, the need for companies to sign up for sustainable projects requires the forging of partnerships with collective groups and associations that far exceed any regulatory requirements. Our proposals will be supported by the analysis of two sites. In Bodonou (Finistère) a good industry/local communities partnership has resulted in the reclaiming a protected natural area (wetland, natural heritage ...) after the closure of the site. Off shore Lorient, the local opposition to the possible opening of an extraction site at sea demonstrates the civic commitment to environmental issues, and, more broadly, to the preservation of a quality living space.
