“Fashion has an opportunity to lead with honesty, transparency and a willingness to challenge itself. That’s what excites me about the Insights Board,” McCartney commented. “It’s about listening and learning, not just from the voices around the table, but from the communities they represent, and keeping sustainability front and centre in a way that sparks real dialogue and, importantly, hope for change.”

This is the second time McCartney and H&M have collaborated, after working together on the retailer’s second design collection.

The Board’s first meeting took place in London and explored a range of perspectives on the fashion industry’s current challenges. The group specifically focused on the use of more sustainable and innovative materials, as well as animal welfare.

The news follows shortly after H&M announced a new target of reaching 100% sustainable materials sourcing by 2030.

Daniel Ervér, CEO at H&M, added: “We are excited to start this dialogue that connects different voices and perspectives from across the fashion world. The Insights Board is a unique opportunity to listen, gain new insights and explore how we can move both ourselves and the fashion industry forward.”

Other members of the board include technologist and sustainability innovator Kiara Nirghin, model and brand ambassador Amelia Gray, fashion editor and journalist Susie Lau, model, actress and founder of Gurls Talk Adwoa Aboah and singer and global artist and activist Anitta.

Lau added: “Fashion thrives on dialogue, critique and curiosity. What draws me to the Insights Board is the chance to question assumptions and explore how sustainability can move beyond slogans and become something embedded in the culture and everyday practices of fashion.”
