Background and Problem: Global climate change presents the biggest challenge humanity has ever faced. As the Ecological Footprint metric and behaviour towards sustainable investment can present essential contributions to humanity’s sustainability transition, they have gained significant importance over the last years. However, it is largely unexplored if living and consuming sustainably also affects how savings are allocated when investing. 

Purpose: The purpose of this study is to contribute to the current body of knowledge by studying the motivations and backgrounds that drive the decision of individuals to invest sustainably. Thus, we investigate the relationship between people’s Ecological Footprint and their sustainable investment behaviour.

Method: This study follows a positivist research approach where quantitative data is gathered through a structured questionnaire from 290 respondents with financial literacy and sustainability awareness. The results are analysed through a logistic regression and then interpreted and discussed in the context of the frame of reference. 

Conclusion: The results indicate that individuals with a lower Ecological Footprint and thus a higher awareness of sustainability are more likely to invest sustainably. Consequently, this study showed that individuals who consumed more sustainably tend to act more sustainably in other areas and levels. Moreover, this study adds new knowledge to the literature regarding individual’s consumption behaviour and its relationship with sustainable investments.
