Why sufficiency? Necessity, potentials and legitimacy

The evidence supporting the notion that sustainability goals cannot be achieved solely through technological innovations, but rather by incorporating sufficiency strategies, continues to grow each year (Haberl et al., 2020). The Intergovernmental Panel on Climate Change has now recognized sufficiency as a crucial strategy for achieving climate goals (IPCC, 2022), and an increasing number of energy scenarios are integrating sufficiency approaches, acknowledging their significant potential (Cordroch et al., 2021; négaWatt Association, 2023).

We define sufficiency as a strategy for reducing the consumption and production of end-use products and services through changes in social practices in order to comply with environmental sustainability while ensuring an adequate social foundation for all people.

In this Session, interdisciplinary researchers from Sociology, Political Science and System Modelling will present their research. Three connected presentations and comments by Key Listeners will concern with

a) Meta-Analysis of Climate-neutrality Scenarios with focus on Sufficiency (Luisa Cordroch)
b) Quantitative effects of Sufficiency Policies (Ben Best)
c) How European Citizen Assemblies demand Sufficiency Policies (Jonas Lage)

The research presented in this Session represents intermediate outcomes of the project "Energy Sufficiency in Energy Transition and Society" (EnSu,,

The discussion can cover the political legitimacy for degrowth and sufficiency and criteria to design policy-mixes for sufficiency.
