Business model innovation is an important lever for change to tackle pressing sustainability issues. In this paper, ‘sufficiency’ is proposed as a driver of business model innovation for sustainability. Sufficiency-driven business models seek to moderate overall resource consumption by curbing demand through education and consumer engagement, making products that last longer and avoiding built-in obsolescence, focusing on satisfying ‘needs’ rather than promoting ‘wants’ and fast-fashion, conscious sales and marketing techniques, new revenue models, or innovative technology solutions. This paper uses a case study approach to investigate how companies might use sufficiency as a driver for innovation and asserts that there can be a good business case for sufficiency. Business models of exemplar cases are analysed and insights are gained that will contribute to future research, policy makers and businesses interested in exploring sufficiency.@en
