This document summarizes a presentation given by Oleg Koefoed on sustainability in fashion and the OpenWear project. It discusses the challenges of creating truly sustainable fashion, including the need for experiments on a large scale and opening up processes. It outlines four pillars of sustainability: environment, sociality, economy, and culture. It then defines sustainability as satisfying present needs without compromising future generations' needs. For fashion to be sustainable, it must build resilience through diversity and allow emergence rather than planning. OpenWear and similar projects face concerns around reducing environmental and social impacts while lowering entry barriers only temporarily. True sustainability requires facilitating economic entry, open participation, transparency, and regenerating systems rather than destroying them.
