Stella McCartney has opened London Fashion Week with a curated installation celebrating British material innovation, coinciding with her appointment as an Ambassador of the Sustainable Markets Initiative. The initiative was founded by His Majesty King Charles III in 2020, when he was Prince of Wales, to accelerate private sector action on environmental challenges.
During the event, hosted by the British Fashion Council, His Majesty presented McCartney with a sustainably sourced Mongolian cashmere scarf made by Erdos and embroidered with the Terra Carta seal. The installation brings together a selection of emerging material innovators working to reduce the environmental footprint of fashion.
Featured companies include FEVVERS, Sequinova, Radiant Matter and YATAY. Their work spans plant-based alternatives to feathers, mycelium-based leather substitutes and biobased, plastic-free sequins, reflecting ongoing efforts to develop lower-impact inputs for fashion production.
The exhibition takes place against the backdrop of mounting environmental pressures linked to the global apparel sector. Industry estimates indicate that more than 100 billion garments are produced annually, with fashion accounting for around 10% of global emissions, 20% of global wastewater and a significant share of plastic waste.
The Sustainable Markets Initiative works with business leaders across sectors to advance circular practices and responsible value chains. Within fashion, it connects stakeholders across design, retail and finance to support industry-wide transition efforts. Stella McCartney has also co-founded the SOS Fund, which provides early-stage investment to next-generation material innovators seeking to scale new solutions.
“The Sustainable Markets Initiative is an organisation I have proudly supported since its inception in 2020, and I am so grateful to His Majesty for this recognition. For me, the most important thing about the SMI is that its focus goes beyond discussion to driving action. I am deeply honoured to become an Ambassador.”
For more than two decades, McCartney has built her brand around a cruelty-free model, excluding leather, feathers, fur and exotic skins from her collections. Her work has included investment in alternative materials, engagement with regenerative agriculture, supply chain transparency initiatives and early publication of environmental impact reporting.
By bringing material innovators into a London Fashion Week context, the installation aims to demonstrate how scientific research and design can intersect within commercial fashion. The participating companies represent technologies that are already being developed for broader market adoption.
Jennifer Jordan-Saifi, CEO of the Sustainable Markets Initiative, said: “We are proud to welcome Stella McCartney as an official Sustainable Markets Initiative Ambassador as we continue to accelerate the private sector shift toward circular and responsible fashion. As a pioneer in sustainable fashion, her expertise and unwavering commitment will help drive meaningful progress across the sector. Stella’s leadership is deeply aligned with the Sustainable Markets Initiative’s Fashion Task Force, chaired by Federico Marchetti, which, together with the Circular Bioeconomy Alliance, promotes regenerative practices and supply chain transparency through digital passports. Together we are joining forces to put Nature, People and Planet at the heart of global value creation.”
A member of the Sustainable Markets Initiative Fashion Taskforce since 2020, McCartney’s new role formalises her involvement in the group’s work on circularity and material innovation. The installation will also be showcased at the Sustainable Markets Initiative 2026 Roundtables and Exhibition at Hampton Court Palace in March.
