ReZeitKon (German acronym for Time Rebound, Time Prosperity and Sustainable Consumption) is an inter- and transdisciplinary research and development project funded by the Federal Ministry of Education and Research (BMBF).

Research partner in the project are TU Berlin, Division of Economic Education and Sustainable Consumption (focus of expertise: consumption research, human resource research, psychologicaltime research and social scientific rebound research), Leuphana University Lüneburg, Institute for Environmental Communication (focus of expertise: education for sustainable consumption) and the Fraunhofer Institute for System and Innovation Research ISI, Karlsruhe (focus of expertise: prospective environmental modelling, psychological and econometric rebound research).

The project will be accompanied by an advisory board of prominent representatives of relevant civil society institutions that have dealt with the relationship of time and resource consumption with regards to work, education and private life for a long time.

 

So far, time rebound effects are understood in the literature as the additional consumption of natural resources due to the use of time that has become “free” through the application of efficient technology and processes or the reduction of working hours. Concurrently with the additional environmental burdens, the intensified use of time often leads to a subjective feeling of time pressure. In the ReZeitKon project, we call this paradoxical negative effect on the subjective perception of time due to the intensified use of “time saving” technical devices the direct time rebound effect. The environmental effect described above we call indirect time rebound effect. Considering subjective time perception, we amplify the time rebound research by a significant component.

In the ReZeitKon project we aim to empirically investigate the significance of time reboundeffects for (ecologically) sustainable consumption, under specific consideration of subjective time perception. On this basis, we deduce and put to test appropriate measures for the reduction of time rebound effects.
