FULFILL Project - Fundamental Decarbonisation Through Sufficiency By Lifestyle Changes
2021 - 2024

The 3 year social science research project called FULFILL - "Fundamental Decarbonisation Through Sufficiency By Lifestyle Changes" has started in October, 2021. The Project is a cooperation among organisations of Fraunhofer Institute ISI, (coordinator) and Wuppertal Institut in Germany, EURAC and POLIMI in Italy, negaWATT and Jacques Delors Institute in France, Green Liberty in Latvia, and INFORSE-Europe in Denmark.

The main objective of the Project is to study lifestyle changes as part of European decarbonisation pathways that lead to the fulfillment of the Paris Agreement goals by using the concept of sufficiency as a guiding principle.

To achieve this overarching project aim, FULFILL has the following objectives:
- Characterize the concept of lifestyle change based on the current literature and extend this characterization by combining it with the sufficiency concept.
- Develop a measurable and quantifiable definition of sufficiency to make it applicable as a concept to study lifestyle changes in relation to decarbonisation strategies.
- Generate a multidisciplinary systemic research approach that integrates micro, meso, and macro level perspectives on lifestyle changes.
- Study lifestyle change mechanisms empirically through social science and humanities (SSH) research methods on the micro (individual, household) and the meso (community, municipal) level.
- Achieve an in-depth analysis of existing and potential sufficiency lifestyles, their intended and unintended consequences (incl. rebound and spillover effects), enablers and barriers (incl. existing structures) as well as impacts (incl. on health and gender) on the micro level across diverse cultural, political, and economic conditions in Europe and in comparison to India as a country with a very large population and very different lifestyles.
- Assess the dynamics of lifestyle change mechanisms towards sufficiency on the meso level by looking into current activities of municipalities, selected communities and initiatives as well as analysing their level of success and persisting limitations in contributing to decarbonisation.
- Integrate the findings from the micro and meso level into a macro, i.e. national and European, level assessment of the systemic implications of sufficiency lifestyles and explore diffusion pathways.
- Implement a qualitative and quantitative assessment of the systemic impact of sufficiency lifestyles which in addition to a contribution to decarbonisation and economic impacts includes the analysis of further intended and unintended consequences (incl. rebound and spillover effects) as well as broader societal impacts (incl. on health and gender).
- Combine the research findings with citizen science activities to develop sound and valid policy recommendations contributing to the development of promising pathways towards lifestyle change.

Side event on Sufficiency  at UNFCCC COP28 organised by INFORSE, NegaWattt, Fraunhofer ISI. ) December 2023 UNFCCC logoUNFCCC COP28, Dubai, UAE

Saturday, 9 December 2023, Time: 15:00-16:30, Room: SE Room 7 & ONLINE
Title: Sustainable Lifestyles, Sufficiency Supporting Just Climate Action, Stronger NDCs

Sustainable lifestyles, sufficiency, can help reducing emissions in high-emission countries with affluent lifestyles. Policies supporting these should be included in the GST and new NDCs. New European research shows the specific sufficiency actions and policies that can make the difference.
Organised by INFORSE, Association negaWatt, France; Fraunhofer Institute for Systems and Innovation Research - FhG ISI, Germany; Sustainable Energy, Denmark.
