This book helps to solve the problem of ineffective pro-environmental programmes and marketing tools, which are currently used by enterprises to make their activities more sustainable. The authors identify key concepts and strategies of sustainable marketing to highlight the trends and development directions of marketing activities of modern enterprises. Focussing on Poland as a central case study, the book is illustrated with examples of organisations that are implementing sustainable marketing activities that are compatible with the CE model. It also presents the results of studies which examined the pro-environmental marketing efforts of small- and medium-sized enterprises, non-governmental organisations and other actors in Poland. To conclude, the authors put forward recommendations for CE network stakeholders regarding sustainable marketing management, focussing specifically on how to avoid accusations of greenwashing and other unethical organisational behaviour. This book will be of great interest to students and scholars of green marketing, sustainable business and the CE, as well as entrepreneurs and business professionals looking to formulate sustainable marketing strategies.
