In order to find a way into a sustainable future it is essential that the value system of society, which up to now has constituted an obstacle for implementing sustainability, will become the focus of critical reflection and public debate. For this reason, the main goal of this thesis consisted in identifying values and attitudes which support or constrain sustainable development, respectively. Central publications in this matter (e.g. CROMPTON et al., 2008) where the decisive factors for choosing this research question. Further aims of this thesis were the analysis of value-based factors for success, constraint and motivation in sustainability processes in practice as well as theoretical and practical thoughts on a change of values in society. These aims were achieved carrying out an interdisciplinary research and analysis of literature as well as qualitative, structured surveys of experts. Thus it was possible to extract a total of approximately 230 supportive and approximately 95 constraining values subsequently synthesized to 15 or 6 groups of similar sets of values, respectively. Among other findings, the analysis shows that values based on empathy, solidarity, cooperation and respect for nature support a sustainable development. In practical transition processes values such as connection and appreciation, common visions and responsibility will result in more success and additionally help to motivate people. These are contrasted by values constraining sustainability, which among others include self-centered values (e.g. image, power, competency), monetary-material values (e.g. greed, wealth, increase in profits) as well as anthropocentric extremes (such as man being the measure of all things). Apart from that, however, there are also ambivalences (e.g. striving for security) and contextualities (e.g. participation) of values. In many cases, achieving a balance between a value and its counterpart (e.g. anthropocentrism biocentrism) will be more advantageous than a unilateral expression of values. The essential change of values can considerably be supported by the exemplary effect of every individual and the cooperation of existing initiatives.
