Maison du Développement durable

Founded in 2007 by the City of Ottignies-Louvain-la-Neuve and the Université catholique de Louvain (UCLouvain), the Maison du Développement Durable (MDD) serves as a hub for local ecological and social transition initiatives. It acts as a catalyst for projects, fostering collaboration among citizens, associations, businesses, and public institutions to create a more sustainable territory.

MDD’s key missions include:

• Bringing together local stakeholders engaged in the transition and supporting them in developing tangible projects.

• Raising public awareness through events, conferences, workshops, and educational programs.

• Experimenting with sustainable solutions and showcasing exemplary ecological and social practices.

• Providing resources via the Recueil de la Transition, a directory of local initiatives, and the Carte de la Transition, which maps active projects.

MDD’s Focus Areas
