Exposure to environmental hazards, such as air pollution and noise, is not evenly distributed across population groups. In fact, socioeconomically disadvantaged people are generally exposed to increasingly intensive environmental hazards.

Until now, both objective and subjective methods have been used to assess the distribution of environmental hazards. These include participatory approaches in which people define and indicate their exposure to environmental hazards themselves. However, until now, such measurements have not reflected the subjective experience of fairness and equity in the distribution of environmental hazards.

The DASEIN study (Digitale Bewertung der subjektive Umweltbelastung und der Ungerechtigkeit in der Umwelt) aims to use digital technology to provide evidence for subjective assessments of environmental justice and injustice. To this end, participants will report subjectively in real time on environmental burdens via a smartphone app and evaluate them in terms of perceived justice and injustice. The study also aims to investigate whether the subjective experience of injustice is influenced by other factors.
