Nine out of ten companies are micro-enterprises with fewer than ten employees. This book demonstrates that CSR management and sustainability orientation are not just topics for large corporations. Micro- and sole proprietorships also benefit from the strategic integration of CSR into their core business. Renowned experts in this book bring global CSR and sustainability requirements closer to micro-enterprises and open up the discourse at the grassroots level of our medium-sized economy. The book presents successful models for profitable CSR activities in micro-enterprises. Through inspiring practical examples, it stimulates one's own innovative potential. The book is suitable for owners of micro-enterprises and aspiring entrepreneurs. At the same time, it supports an economic policy focused on promoting sustainability.
