In Switzerland, more than 200 municipalities have a sustainability approach. Governance and organisational processes can play a decisive part in its success or failure. The objective of the present analysis was to establish an inventory of practices, their achievements and the obstacles encountered with a sample of municipalities of Western Switzerland. Two different approaches could be detected - Local Agenda 21 and a transversal or horizontal sustainability approach. A majority of the municipalities consider Local Agenda 21 to be an inflexible listing of heterogeneous actions, showing difficulties to be introduced into operative management. A transversal approach seems to encounter fewer obstacles. Independently of the chosen approach, no controlling or evaluation of what had been achieved was carried out; at the same time all municipalities regret the lack of a standardised framework with criteria and indicators that allow controlling and evaluation. However, all municipalities of the sample want to continue on their way to a sustainable township. In our opinion, either approach (Local Agenda 21 or a transversal approach) can be successful - what seems to matter is integration into strategic and operative management.
