What is the ultimate responsibility of companies? Fifty years ago, the consensus was that the answer to this question should be maximizing profit and shareholders’ value. Today, however, the answer is more complex. Companies are increasingly being held accountable for environmental and social responsibilities, in addition to their economic performance. As a result, the traditional principles of marketing developed during the 20th century are also being challenged and revised to embrace sustainability as a core component of business. Sustainable marketing is the process of creating and delivering value to customers in a manner that respects or enhances both the environment and society. Through lectures, case studies, interactive discussions, and guest speakers, students in this course will learn about the principles of sustainable marketing across various industries (e.g., apparel, food, automotive, technology), as well as gain a deep understanding of the sustainable consumer. By the end of the course, students will be equipped with the knowledge and skills necessary to develop effective sustainable marketing plans that can drive positive change in the business world. In line with these learning objectives, the course is divided into three main modules: (1) Defining sustainable marketing, (2) Understanding the sustainable consumer, and (3) Developing a sustainable marketing plan.
