Comprehensive research is carried out on consumers with respect to their sustainable behaviour in private life. Other research focuses on employees and their sustainable behaviour in business life. This divide also characterises companies" activities for promoting sustainable consumption and lifestyles. But how can both sides being brought together? Is it possible for companies to initiate a spillover in the sustainable routines of their employees from work to private life? In the transdisciplinary project "Sustainable behaviour at work and in private life", empirical research was conducted on the interests and opportunities of Austrian companies for promoting a spillover in sustainable behaviour. The project is innovative in that it "builds bridges" in two ways. First of all, it links social and ecological fields of action within companies (health promotion including sustainable nutrition, physical exercises and work-life balance, on one hand, and sustainable mobility, on the other). Secondly, the project "bridges" the perspective of managerial staff and the everyday life perspective of employees. The paper presents first empirical results of this study. Insights concern the behavioural spillover, the success factors for companies" "sustainability activities" and the perspectives of management and employees. Against this backdrop it is recommended to enrich workplace health approaches with environmental factors (and not conversely). Finally, a crucial insight into social learning in companies is presented, which could help to promote sustainable behaviour at work and in private life.
