Energy and GHG saving potentials of sufficiency measures - a synthesis for Germany

Dezember 2025

The sixth assessment report of the Intergovernmental Panel on Climate Change (IPCC) emphasises the potential of demand-side measures, such as sufficiency, for mitigating climate change. Although quantified potentials of various sufficiency measures exist, policy advisors and energy modellers critici

Beyond technology and energy supply. Conceptualising a toolbox for including sufficiency measures in scenario projections

Dezember 2025

This work gives an overview on findings from a five-years’ sufficiency research project regarding the tools in the box for modelling sufficiency in the German energy system context. We conceptualize sufficiency quantification by distinguishing between demand-side and supply modelling, external qua

Follow-up | Overview of Renewable Energy Spatial Planning and Designation of Acceleration Areas in Selected EU Member States

Oktober 2025

This study presents an updated overview of the efforts made by 10 selected European Member States (MSs) to implement the amended Renewable Energy Directive (RED III) concerning mapping for renewables. Specifically, it examines Art. 15b, which mandates MSs to conduct a coordinated spatial mapping for

Electricity market design for 100 % renewable energy in Germany – Challenges and solutions

Juni 2025

The transition to a renewable energy system poses several challenges for electricity market design. This paper examines the structural changes required to accommodate a fully renewable-based electricity system in Germany, emphasising the integration of renewable energy sources, dispatchable power pl

Feasibility of sufficiency policy instruments. An assessment using impact chains for the German mobility sector

Januar 2025

The transport sector is not on track to meet the Paris Agreement climate targets. Rapid decarbonization of transport requires fuel switching and energy savings through modal shift and demand reduction – which are the aims of transport-sufficiency policy. We analyze passenger transport-policy instr
