"With CSR having moved from ideology to reality, organizations increasingly make CSR the very heart of their existence. Despite the fact that literature is plentiful with advice on how organizations should design, implement, control, and measure their CSR involvement, unresolved issues still exist, however. Dr. Pia Popal’s new book Small and Medium Sized Enterprises and Sustainability examines why German small and medium-sized enterprises engage with international institutions for voluntary self-regulation such as the UN Global Compact. Where research previously has focused on behavior, Dr. Popal’s research focuses on institutionalized practices. Dr. Popal’s book is a most welcome read and offers important contributions to CSR literature. I recommend the book heartedly."Professor, Dr. Adam Lindgreen, Head of Department of Marketing, Copenhagen Business School and Extraordinary Professor, Gordon Institute of Business Science, University of Pretoria
