Luxembourg in Transition is a process in which 10 international multidisciplinary teams of architects, urban planners, landscape designers and other industry professionals are, between mid-2020 and the end of 2021, envisioning scenarios and proposals for how the territory of Luxembourg and its border regions can achieve carbon neutrality by 2050. The Department of Spatial Planning of the Ministry of Energy and Spatial Planning has decided to accompany this process with a Citizens’ Committee, the Biergerkommitee Lëtzebuerg 2050.
