We provide new insights about the investor group heterogeneity in the field of sustainable investing. Using survey data from 3,667 German financial decision makers, we conduct two empirical analyses. First, we investigate the influence of various factors that promote sustainable investing by individual investors and find a new investor group which we call: Divesting Investors. Second, we analyze the differences with regard to the perceived investment obstacles between the investor groups that do not want to (further) invest sustainably or want to withdraw capital from sustainable investments.
