Indirect Rebound Effects. Lifestyle-segmentation and Interventions with Efficiency-Feedback and Sufficiency

Funding Measure „Rebound-Effekte aus sozial-ökologischer Perspektive“

The iReliefs project contains four subprojects (SP):



Microeconomic quantification of indirect rebounds based on consumption data

CAU VWL, Prof. Dr. Katrin Rehdanz

Chair of Environmental and Energy Economics

The subproject “Microeconomic Quantification”, which is, like the subproject “Tracking indirect rebounds via feedback application”, located at Kiel University, focuses on the quantification of direct and indirect rebound effects at consumer/household level using existing purchase data for Germany.

CAU VWL first calculates the carbon footprint (CF) for different consumption areas (consumption balance) over time on the basis of an input-output model. The calculation is carried out for the average household in Germany as well as for different household types.

Subsequently, private households’ demand for different goods and services is modelled and direct and indirect rebound effects are estimated with the help of econometric regression methods, taking into account income and substitution elasticities.

Sufficient lifestyles and consumption styles as impulse generators for indirect rebounds: A shopping basket-specific analysis

University of Potsdam, Prof. Dr. Ingo Balderjahn


Intervention studies

(in cooperation with LMU Munich)

Chair of Business Administration with focus on Marketing

The subproject “Rebound and Backfire Effects of Sufficient Lifestyles” focuses on indirect rebound effects due to sufficient consumption practices and simple lifestyles. Via work packages SP2 and SP4, the subproject investigates the occurrence of indirect rebounds (order of magnitude, rebound patterns and influencing factors) and tests target-group-specific measures to reduce or avoid sufficiency rebounds.

The planned work in SP2 aims to quantify sufficiency rebounds of reduced lifestyles and consumption styles on the basis of two data sets representative for Germany and to reveal rebound patterns as well as exchange relationships between consumption areas. The quantification is carried out by a comparative shopping basket analysis for sufficient and non-sufficient lifestyles, as well as the development and testing of two different measurement approaches.

The work package SP4 aims to develop target group-specific measures to reduce indirect sufficiency rebounds and to evaluate them by means of various practical interventions (pre-survey, intervention, post-survey and follow-up). The development of measures is based on a preliminary study on target group specific rebound patterns and is being conducted in close coordination with the LMU Munich as well as the practice partners.

Tracking of indirect rebounds via feedback application

CAU BWL, Prof. Dr. Stefan Hoffmann

Chair of Marketing

The subproject “Tracking indirect rebounds via feedback application” aims to develop a new methodology for tracking indirect rebounds. CAU BWL will use the Eco2log application to collect consumption data of individual consumers from selected product areas sequentially in a longitudinal section and determine the carbon footprint (CF) of the test persons. With the help of the Eco2log app, different interventions are switched in different product categories. This allows indirect rebound effects on other product areas to be identified. Moreover, the emergence of moral licensing will be tested and how indirect rebound effects can be transformed into positive economic effects.
CAU BWL also conducts pre-studies on the content of the app in the first year of the project. In several surveys of the customers of the partner companies from the areas of sustainable textiles and food as well as electromobility, the occurrence of indirect rebound effects in various consumption areas is examined. In addition, the influence of “events” in terms of the use of efficient devices will be examined (e.g. planned analysis of the users of e-bikes in cooperation with a practice partner).

Intervention Studies

LMU Munich, Prof. Dr. Bernhard Gill (in cooperation with the University of Potsdam)


Chair of Business Administration with focus on Marketing



Chair of Political Sociology of Social Inequality

Subproject 4 “Intervention studies” focuses on the research, development and testing of the effectiveness of interventions to avoid indirect rebound effects resulting from sufficient consumption. The focus of the LMU in this context is on the social scientific monitoring of the research, development, implementation and evaluation of interventions in close cooperation with the University of Potsdam. In addition to literature studies and discussion rounds with practice partners, the LMU conducts in-depth interviews to determine the range of indirect rebounds. In this way it makes a substantial contribution to target group-specific intervention measures. The design of the intervention and the analysis of the effectiveness of the respective interventions in terms of reducing the carbon footprint (CF) of private households is carried out in close cooperation between the LMU Munich and the University of Potsdam.
