While technical perspectives consider scale as function of size, debates on the politics of sustainability transitions tend to translate scale into political levels, shaping or impeding the development of sustainable modes of production and consumption. The debate on the “Politics of Scale” in critical human geography foregrounds scale as a social construction reflecting uneven relations of power, political strategies and contestations. This chapter applies the perspective of the “Politics of Scale” to the two German lignite mining regions of Lusatia (Lausitzer Revier) and Rhineland (Rheinisches Revier). Both regions have a long history in the extraction of lignite. This history is about to end following the political decision to phase out the use of lignite in Germany. In consequence, the former lignite regions are becoming not only sites of the transformation of energy infrastructure, but also of structural change and extensive efforts for realising a just transition process. We discuss these transitions from a scalar perspective and through three analytical prisms: first, the impact of national policy as a shifting context for regional policy and as an example of the rescaling of regional development; second, the emergence of new scales of regional development strategies as a new scalar fix of regional governance; and third, the contestations of the phasing out of lignite on different geographical scales and as an example for jumping scales of various actors in the regions. These three emblematic lenses will enable us to discover the scalar dimension of the efforts for just transitions.
