Sometimes when we say we work with sustainable fashion people look at us like... "Mmmm, is it really possible for something like fashion to be sustainable?" And let's face it, people are right being suspicious. If anything the fashion industry has become increasingly unsustainable over the last decades, using more and more natural resources and creating more and more waste. In this course, we provide an overview of business model theory and discuss business models as essential tools in the transformation towards more sustainable businesses. Throughout the course, we will use business model theory as a foundation to look at how real-world fashion brands are adopting more sustainable ways of doing business. We will provide you with rich opportunity to examine their efforts and consider strategies for your own organisation. Hopefully, you can also enlighten us with some local examples in your own countries for us to discover together new ways of dealing with sustainability. By the end of the course you have an understanding of the overall challenges and potential solutions for businesses to become more sustainable. You will learn about the challenges and opportunities of implementing circular business models and we will introduce various tools that companies use to measure and report about sustainability. You will be able to think about business model theory in new ways and apply strategies to manage business model innovation towards sustainable practices. This is a very exciting time to be working in the fashion industry, so let's get started!
