Sustainability can be complex to measure, so one of the metrics we use to gauge how we’re doing is our Fibre Tool. We take a holistic perspective when evaluating the fibres we use, looking at the whole lifecycle of a piece of clothing rather than a single phase. This means that we balance the durability and circularity of fibres throughout their lifespan with the impacts of their creation.
To guide us, we developed our own Fibre Tool in 2012, based on research from MadeBy and Nike, but encompassing Filippa K’s values of quality and longevity. It gives us a score based on a fibre’s impact of production while also considering the durability and full lifecycle. As this is only part of the equation, we are working to measure further impacts in our supply chain.
The Fibre Tool gives fibres score between 1 and 4: class 1 and 2 fibres are considered “more sustainable”. We update this tool regularly, and our designers find it helps them make more conscious choices while maintaining the signature quality, longevity, and aesthetics of Filippa K.
