This book describes the sustainable development journey of 15 business families committed to using their enterprises as a force of societal good. In turn, each family reaps benefits of high economic returns, while contributing to society and environment. The youngest family firm is in its 20s, while there are others over 100 years of age. Size, industry, locations vary. But all these business families share a deep shared commitment towards sustainable development, control over strategic decision-making in their firms and trans-generational continuity intentions. Family values embed their enterprises with a strong sense of purpose to achieve their chosen sustainable development goals. Professionalized systems and processes foster the development of capabilities, and partnerships with a variety of stakeholders ensure the simultaneous achievement of social, environmental and profitability goals.
